`(Twice Amended ) A method of treating an angeological
`disease at a bifurcation site where a blood vessel branches into a first
`branched vessel and a second branched vessel using a birfucation prosthesis
`[stent] having a bifurcation, a proximal portion, a first distal portion, and an
`extension portion extending distally relative to said bifurcation, and using a
`second prosthesis [stent], said method comprising the steps of:

`59. (Amended) A bifurcated prosthesis [stent] for use [in
`juxtaposition] with an angeological bifurcation of a blood vessel into two
`branched vessels comprising a bifurcated proximal [stent] portion adapted to
`be disposed within said blood vessel [in juxtaposition with said bifurcation], a
`distal [stent] portion adapted to extend across the bifurcation into one of the
`branched vessels, and a separate distal [stent] segment joined to said proximal
`portion and adapted to allow blood to flow from the proximal portion into the
`other branched vessel.
`
`(Amended) A method as claimed in claim 55 further

`
`covering at least a portion of said proximal portion, said
`(d)
`first distal portion, and said second prosthesis [distal portion] with a graft
`layer.

`
`comprising:
`
`an upper limb, configured to fit within the lumen upstream of
`the bifurcation;
`
`a first lower limb, configured to extend into a first leg of said
`bifurcation when said first section is positioned in the lumen, and
`
`a second lower limb, shorter than said first lower limb, and
`configured so that when said first section is positioned in the lumen, said
`second lower limb does not extend into a second leg of said bifurcation.
`
`(Newly added) The apparatus of claim 89, further
`90.
`comprising a second section configured to be positioned separately within the
`lumen and joined to said second lower limb of the first section, effectively
`extending said second lower limb into said second leg of said bifurcation.
`
`REMARKS
`
`Response to Restriction Requirement
`
`Applicant hereby confirms the election of Group I, claims 55,
`59, and 62-65, for further prosecution in this application. This election is
`made without traverse. Claims 55, 59, and 62-65 were pending in this
`application as of the issuance of the Office Action. By this amendment,
`Applicant has added claims 88, 89 and 90, all of which are directed to the
`same invention as the elected claims.

`
`Response to Pending Rejection
`
`Claims 55, 59, and 62-65 stand rejected in the Official Action
`under 35 U.S.C. § 102(e) as anticipated by U.S. Patent No. 5,575,817
`(Martin).
`
`Martin was filed on August 19, 1994. The present application is
`a divisional of application Serial No. 08/317,763, filed October 4, 1994,
`which is in tum a continuation-in-part of application Serial No. 08/312,881,
`filed September 27, 1994. Both of these applications have effective filing
`dates based on two EPO applications, one filed February 9, 1994 and one
`filed June 10, 1994. The priority claim to the EPO applications antedates the
`August 19, 1994 filing date of Martin, thus eliminating the patent as a
`reference against this application. Eliminating this patent as a reference
`' obviates the claim rejections over Martin. Withdrawal of the rejection of the
`claims based on this reference is therefore respectfully requested.
`
`Priority of the same EPO applications is made and
`acknowledged in the parent and grandparent applications, and certified copies
`of the EPO priority applications were filed in both of those cases. Applicant
`understands that no certified copy need be filed in the present case because of
`the prev:ious filings in the parent cases, but Applicant will do so if requested
`by the Examiner.
`
`Claims 55, 59, and 63 have been amended, and claim 88 has
`been added, to better define Applicant's invention. Newly added claims 89
`and 90, copies of claims 1 and 2 in the cited Martin patent, are also clearly
`patentable to Applicants for the same reasons stated with regard to the
`pending rejections (see further discussion below regarding Applicant's request
`for an interference to be declared between this application and the Martin
`patent).
`
`\
`\
`
`In light of the above amendments and remarks, it is respectfully
`submitted that the claims of the present application are in condition for
`allowance, which action is earnestly solicited.

`
`-*'" Request for Declaration of Interference
`
`In view of the fact that the reference relied upon in the pending
`rejection is an issued patent, which issued within the past six months, and the
`recognition in the rejection statement that Applicant appears to be claiming the
`same invention as disclosed in the reference, Applicant respectfully suggests
`
`ll that an interference should be declared between this application and the cited
`\ reference. In furtherance of this suggestion, Applicant has added new claims
`ffl \ 89 and 90, which are copies of claims I and 2 of the cited patent.
`Accordingly, Applicant respectfully requests that an interference be declared
`with at least one count corresponding to each of claims 89 and 90 hereof
`(claims 1 and 2 of Martin).
`
`As explained above, the effective filing date of the present
`application is believed to be February 9, 1994 by virtue of the priority claims
`in this application. Because this effective filing date antedates Martin's filing
`date, Applicant should be senior party in any interference that is declared.
`
`As a matter of information, Applicant has also proposed that the
`Interference between Applicant and the Martin patent encompass claim 66 of
`Applicant's U.S. application Serial Number 312,881, filed September 27,
`1994, and claims 63 and 65 of Applicant's U.S. application Serial Number
`~63,987, filed June 5, 1995.
`
`Upon declaration of the Interference, Applicant will place each
`of the interfering claims of its various applications into a single application,
`request that they be added to the Interference, and cancel them from the
`respective applications in which they now appear.
