`INSTRUCTIONS FOR USE
`EXCLUDER BIFURCATED ENDOPROSTHESIS
`
`Carefully read all instructions prior to use. Observe all warnings and precautions noted
`throughout these instructions. Failure to do so may result in complications.
`DESCRIPTION
`The EXCLUDER Bifurcated Endoprosthesis (EXCLUDER Endoprosthesis) is a device that provides
`endovascular treatment of infrarenal abdominal aortic aneurysms (AAA).
`The EXCLUDER Endoprosthesis is comprised of two components, the Trunk-Ipsilateral Leg
`Endoprosthesis (Trunk) (Figure 1) and the Contralateral Leg Endoprosthesis (Figure 2). The graft
`material is expanded polytetrafluoroethylene and fluorinated ethylene propylene (ePTFE and FEP),
`and is supported by nitinol wire along its external surface. Nitinol anchors and an ePTFE/FEP sealing
`cuff are located near the aortic end of the trunk. An ePTFE/FEP sleeve is used to constrain the
`endoprostheses on the leading end of the delivery catheters (Figures 3A, 3B, and 3C).
`Deployment of both endoprosthesis components initiates from the leading (aortic) end and proceeds
`toward the trailing (iliac) end of the delivery catheter. The ePTFE/FEP sleeve remains in situ between
`the endoprosthesis and the vessel wall.

`INTENDED USE
`The EXCLUDER Endoprosthesis is intended to exclude the aneurysm from the blood circulation in
`patients diagnosed with infrarenal AAA disease and who have appropriate anatomy.
`CONTRAINDICATIONS
`Known contraindications include, but are not limited to:
`•
`Significant thrombus at the arterial implantation sites, specifically proximal aortic neck and distal
`iliac artery interface
`Severe proximal aortic neck angulation > 60°
`Infrarenal aortic neck < 15 mm in length
`Ilio-femoral access vessel morphology which is not compatible with vascular access techniques,
`devices and accessories.
`WARNINGS
`• Minimize handling of the constrained endoprosthesis during preparation and insertion to
`decrease the risk of endoprosthesis contamination and infection.
`Do not advance the device outside of the sheath.
`Do not rotate the Trunk or the Contralateral Leg delivery catheter while the endoprosthesis is
`inside the introducer sheath. Catheter breakage or premature deployment may occur.
`Do not rotate the Trunk delivery catheter beyond 360° to avoid delivery system damage and/or
`premature deployment.
`Do not rotate the Contralateral Leg delivery catheter during delivery. Catheter breakage or
`premature deployment may occur.
`Do not attempt to withdraw the undeployed endoprosthesis through the 18 Fr or 12 Fr introducer
`sheath valve. The sheath and catheter must be removed together.
`Do not attempt to reposition the endoprosthesis after deployment has been initiated. Vessel
`damage or device misplacement may result.
`Do not continue advancing any portion of the delivery system if resistance is felt during
`advancement of the guidewire, sheath, or catheter. Stop and assess the cause of resistance.
`Vessel or catheter damage may occur.
`Incorrect deployment or migration of the endoprosthesis may require surgical intervention.
`Do not cover significant renal or mesenteric arteries (exceptions are inferior mesenteric and ilio-
`femoral) with the endoprosthesis. Vessel occlusion may occur.
`Do not use delivery catheter for high pressure fluid injections.
`•
`PRECAUTIONS
`•
`Do not resterilize; for single use only.
`•
`Do not use if damaged or if sterile barrier has been compromised.
`•
`Do not use after the “use by” (expiration) date printed on the label.

`
`SUMMARY OF CLINICAL STUDIES
`
`OBJECTIVES
`The primary objective of the clinical study was to demonstrate that the EXCLUDER Bifurcated
`Endoprosthesis is a safe and effective alternative to open surgical repair in the primary treatment of
`infrarenal abdominal aortic aneurysms. Safety was determined by demonstrating that the EXCLUDER
`Bifurcated Endoprosthesis subjects would have a total proportion of major adverse events that is less
`than the subjects treated with open surgical repair as evaluated through one year follow-up.
`Effectiveness was based on exclusion of the aneurysm including the absence of an endoleak, the
`absence of aneurysm enlargement (≥ 5 mm), and the absence of major device efficacy adverse
`events evaluated through one year follow-up. Secondary objectives included an assessment of
`clinical benefit and quality-of-life measures.
`STUDY DESIGN
`This prospective, non-randomized, multi-center clinical study was designed to compare patients
`treated with endovascular repair to an open surgical repair control group. The control group included
`patients whose vascular anatomy (proximal aortic neck length, proximal neck angulation, and arterial
`implantation site condition) may not have been suitable for endovascular AAA repair. The planned
`ratio of EXCLUDER Bifurcated Endoprostheses to control subjects was approximately 2:1. Follow-up
`evaluations were scheduled for pre-discharge, 1-month, 3-months (if endoleak at 1-month),
`6-months and 12-months. An independent Core Lab facility reviewed CT scans and abdominal x-rays
`to assess aneurysm diameter changes, device and relative component migration, device integrity
`(wire and graft) and the presence and type of endoleaks.
`DESCRIPTION OF SUBJECTS
`Nineteen U.S. sites enrolled 235 EXCLUDER Bifurcated Endoprostheses and 99 control subjects.
`Given the epidemiology of AAA and surgical repair, males predominated over females
`(83% compared to 17%). The selection criteria for the study were based on enrolling subjects with
`the appropriate anatomy for endovascular repair. A total of 31 females were treated with EXCLUDER
`Bifurcated Endoprostheses and 26 with open surgical repair. For subjects treated with EXCLUDER
`Bifurcated Endoprostheses, there were no differences between males and females for results through
`one year for survival, freedom from major adverse events and cumulative adverse events. For open
`surgical repair subjects, females compared to males as follows: results at one year showed that
`females had a lower rate of cumulative adverse events (0.4 vs 0.8 with p=0.003), comparable
`freedom from major adverse events, and a slightly lower survival rate (87% vs 97% with p=0.07).

`Tables 4-11 describe results of the EXCLUDER Bifurcated Endoprosthesis subjects as reported by the
`Core Lab. Device performance factors analyzed by the Core Lab included device integrity (Table 4),
`device patency (Table 5), migration (Tables 6 and 7), and anuerysm exclusion (Tables 8-11). For
`device performance factors, more than one incident can occur to one subject and incidents are not
`necessarily viewed at every time point for one subject. Device integrity encompasses the structural
`findings of the wire-form via abdominal x-ray images at the corresponding follow-up timepoints.

`CONCLUSIONS FROM CLINICAL STUDIES
`As compared to conventional open surgery, the clinical benefits of the EXCLUDER Bifurcated
`Endoprosthesis are a lower rate of major complications, reduced blood loss and blood replacement
`volume, reduced need for an ICU stay, shorter hospitalization and faster return to normal activities.
`The risks include procedure- and/or device-related phenomenon, which include but are not limited to
`endoleaks and increase in aneurysm size.

`
`DIRECTIONS FOR USE
`
`•
`
`•
`
`Pre-Treatment Planning
`•
`Determine accurate size of anatomy and proper size of Trunk-Ipsilateral and Contralateral
`Endoprosthesis (Tables 14 and 15).
`Use high resolution, non-contrast and contrast enhanced computerized tomography (CT) at
`≤ 3 mm acquisition and reconstruction collimation.
`Use multiple view, digital subtraction angiography with a radiopaque marker catheter or spiral
`CT multi-planar reconstruction.
`For angiography, use correct imaging angulation (cranial-caudal, lateral-oblique) to accurately
`identify origin of branch vessel anatomy.
`Consider breath-hold technique to optimize digital subtraction angiography image quality.

`
`Anatomical Requirements
`For Trunk-Ipsilateral Leg Endoprosthesis: Proximal aortic neck angulation ≤ 60° with minimal
`•
`thrombus and/or calcification.
`Proximal aortic neck length ≥ 15mm.
`Non-aneurysmal iliac artery length ≥ 10 mm
`For Contralateral Leg Endoprosthesis: Non-aneurysmal iliac artery length ≥ 10 mm
`Ilio-femoral access vessel morphology should be compatible with vascular access techniques,
`devices and accessories.
`Arterial Access and Angiography
`1.
`Following standard practices, access the intended contralateral side via a percutaneous
`diagnostic sheath, and perform marker catheter digital subtraction angiography (AP, oblique and
`lateral views as necessary) to confirm the correct device component sizing, and deployment
`locations. Consider breath-hold technique to optimize image quality. Leave marker catheter in
`place at the level of the renal arteries.
`Following standard practices, perform percutaneous access and/or surgical exposure of the
`vessels selected to receive the Trunk-Ipsilateral and Contralateral side introducer sheaths.
`Following the manufacturer’s instructions for use, advance an 0.035” (0.89 mm) ‘super-stiff’
`guidewire, or acceptable equivalent to the level of the renal arteries.
`Following the manufacturer’s instructions for use, prepare and advance the 18 Fr diameter x 30 cm
`length, introducer sheath/dilator over the guidewire, through the ilio-femoral anatomy, aortic
`aneurysm and up to the level of the proximal aortic neck according to standard practice.
`5. Administer heparin according to standard practice.
`6. Use standard heparinized saline, pressure flush system technique to prevent thrombus formation
`in the introducer sheaths.
`7. Use an accurate radiopaque patient marking method to assure accurate device positioning and
`deployment locations.
`Catheter Preparation
`1. Use new, sterile gloves and minimize handling the endoprosthesis portion of the delivery
`catheters.
`2. Remove the appropriately sized Trunk-Ipsilateral and Contralateral Leg delivery catheters from
`their packaging and examine for possible damage.
`3. Remove protective packaging mandrel and packaging sheath(s) from the leading end of the
`delivery catheters (Figure 3A).
`Flush with heparinized saline through the flushing port on the trailing end of the delivery catheter
`(Figure 3A).
`Follow the manufacturer’s recommended method for size selection, preparation and use of aortic
`and iliac dilation balloons. Carefully inflate the balloon to avoid complications.
`Trunk-Ipsilateral Leg Endoprosthesis Positioning and Deployment
`1. Use fluoroscopic visualization for all guidewire, sheath and device catheter manipulations.
`2. Advance the Trunk delivery catheter over a 0.035” (0.89 mm) ‘super-stiff’ guidewire, through the
`18 Fr x 30 cm long introducer sheath into the aorta to the approximate level of intended
`positioning. Warning: The catheter should not be rotated while the endoprosthesis is within
`the introducer sheath to avoid premature deployment.
`3. While maintaining the delivery catheter in position, withdraw the introducer sheath back to the
`white shaft marker on the delivery catheter (Figure 3A).
`4. Magnify and center the fluoroscopic image on the proximal trunk. Reposition and rotate the
`Trunk-Ipsilateral delivery catheter as necessary to properly position the proximal device marker
`as well as orient the long contralateral, and short ipsilateral radiopaque markers and device
`position on the appropriate side of the anatomy. Maximize the separation between these two
`markers to achieve maximum lateral positioning of the iliac legs of the device. The long marker
`should be oriented toward the contralateral side (Figure 1).
`It is recommended to view and confirm the distal position of the iliac end of the device relative
`to the internal iliac artery to ensure accurate and desired deployment position of the distal
`aspect of device.
`If clinically acceptable, lower the patient’s blood pressure to 60-70 mm Hg during Trunk
`deployment and aortic balloon inflation to decrease blood flow and reduce the risk of
`endoprosthesis movement.
`7. Maintain a contralateral access side sheath, catheter or guidewire in position across the distal,
`native bifurcation to protect and ensure that contralateral access is maintained into the
`aneurysm sac and contralateral leg hole of the device during Trunk-Ipsilateral component
`deployment.

`
`8. Re-center and magnify the image on the proximal Trunk of the device to assure final desired
`position of proximal device relative to anatomy. Stabilize the Trunk delivery catheter at the level
`of entry into the introducer sheath and stabilize the sheath relative to the patient’s access site.
`9. Loosen the deployment knob. Confirm final device position and orientation and deploy the Trunk
`using a steady and continuous pull of the deployment knob to release the endoprosthesis. Pull
`the deployment knob straight out from the catheter side arm. Deployment initiates from the
`leading end toward the trailing end. Warning: Once deployment is initiated, do not attempt to
`reposition the endoprosthesis.
`10. Use fluoroscopic guidance during the withdrawal of the delivery catheter to assure safe removal
`from, and to avoid catching on, the endoprosthesis.
`11. Position the aortic balloon inside the proximal region of the trunk. Avoid balloon contact with the
`flow splitter which is aligned with the long and short radiopaque markers. Inflate and deflate the
`balloon quickly with dilute contrast solution to seat the aortic end of the endoprosthesis. Follow
`the manufacturer’s recommended method for size selection, preparation and use of aortic and
`iliac dilation balloons, carefully monitoring both volume and pressure to avoid complications.
`12. Use fluoroscopic guidance to ensure the balloon is completely deflated and is safely removed
`from the endoprosthesis.
`13. Advance and inflate the appropriate size PTA balloon catheter to seat the iliac end of the
`endoprosthesis. Follow the manufacturer’s recommended method for size selection, preparation
`and use of PTA balloons. Carefully inflate the balloon to avoid complication.
`Contralateral Endoprosthesis Positioning and Deployment
`1. Use fluoroscopic visualization for all guidewire, sheath and device catheter manipulations.
`2.
`Following manufacturer’s instructions for use, advance a 0.035” (0.89 mm) ‘superstiff’ guidewire
`into the contralateral leg hole of the Trunk according to standard practice.
`3. Verify that the guidewire is within the contralateral leg hole of the Trunk by rotating a formed
`pigtail catheter within the Trunk, or by standard practice used to verify guidewire location.
`Following manufacturer’s instructions for use, introduce the 12 Fr x 30 cm long contralateral
`introducer sheath and dilator. Advance the sheath over the guidewire and through the
`contralateral leg hole of the Trunk.
`5. Advance the prepped Contralateral Endoprosthesis delivery catheter to the level of the long
`radiopaque marker (Figure 1). Warning: Do not attempt to rotate the Contralateral Leg
`Endoprosthesis catheter at any point to avoid catheter breakage or premature deployment.
`6. Align the radiopaque marker at the proximal end of the Contralateral Leg Endoprosthesis with
`the long contralateral radiopaque marker on the Trunk-Ipsilateral Leg Endoprosthesis.
`7. While maintaining the delivery catheter in position, withdraw the introducer sheath back to the
`white shaft marker on the delivery catheter (Figure 3A).
`8. Stabilize the Contralateral Leg Endoprosthesis delivery catheter at the level of entry into the
`introducer sheath and stabilize the sheath relative to the patient’s access site.
`9. Loosen the deployment knob. Confirm final device position. Deploy the Contralateral Leg
`Endoprosthesis by using a steady, continuous pull of the deployment knob to release the
`endoprosthesis. Pull the deployment knob straight out from the catheter side-arm. Deployment
`initiates from the leading (aortic) end toward the trailing (iliac) end. Warning: Once deployment
`is initiated, do not attempt to reposition the endoprosthesis.
`10. Use fluoroscopic guidance during withdrawal of the delivery catheter to assure safe removal
`from the endoprosthesis.
`11. Following manufacturer’s instructions for use, advance and inflate a 14 mm PTA balloon catheter
`to seat the proximal end of the Contralateral Leg Endoprosthesis within the contralateral leg hole
`overlap region. Follow the manufacturer’s recommended method for size selection, preparation
`and use of aortic and iliac dilation balloons, carefully monitoring both volume and pressure to
`avoid complications.
`12. Following manufacturer’s instructions for use, advance and inflate the appropriate size PTA
`balloon to seat the iliac end of the Contralateral Leg Endoprosthesis. Follow the manufacturer’s
`recommended method for size selection, preparation and use of PTA balloons. Carefully inflate
`the balloon to avoid complications.
