`
`(57) Abstract
`
`Anapparatusforfacilitating the fusion of adjacent bone structures (V1, V2) includes an implant member (100) configured for insertion
`within a space defined between adjacent bone structures (V1, W2). The implant member (100) includes an entry end portion (114) and a
`trailing end portion (122) and defines a longitudinal axis. The implant member (100) includes at least a longitudinal portion (102) having
`a generally elliptical cross—sectional dimension with a major cross-sectional dimension (a) greater than a minor cross-sectional dimension
`(b). A system (200) for drilling a bore in adjacent vertebrae (V1, V2) to facilitate the insertion of a fusion implant (100) includes a surgical
`retractor (202) having a sleeve member (210) with proximal (212) and distal (214) end portions and defining a longitudinal opening and
`a drill instrument (204) positionable within the longitudinal opening of the surgical retractor (202). The retractor (202) is configured for
`insertion at least partially into an intervertebral space between adjacent opposed vertebrae (V1, V2) to distract the adjacent vertebrae (V1,
`V2) to a desired predetermined distracted position. At least one anchoring member may be associated with the surgical retractor (202) to
`facilitate mounting thereof to the vertebrae (V1, V2). The drill instrument (204) includes an elongate member (220) having a longitudinal
`passageway and defining at least one distal cutting surface and a drill member (224) disposed within the elongate member (220) and having
`a distal drill head. The drill member (224) is rotatably movable within the elongate member (220) and is also longitudinally fixed to the
`elongate member (220) such that advancementof the drill member (224) within the retractor (202) causes corresponding advancement of
`the elongate member(220) suchthat the distal cutting surface of the elongate member (220) and the distal drill head of the drill member
`(224) cooperate to cut a non-circular, e.g., an eliptical-shaped, bore in the adjacent vertebrae (V1, V2). Preferably, the elongate member
`(220) of the drill instrument (204) includes first and second diametrically opposed distal cutting surfaces. The cutting surfaces may be
`arcuately-shaped.

`Box! Observations where certain claims were found unsearchable (Continuation ofitem 1 offirst sheet)
`
`This International Search Report has not been established in respect of certain claims under Article 17(2){a) for the following reasons:
`
`
`
`
`Claims Nos.:

`
`-
`38
`1-
`becausethey relate to subject mattér not required to be searched bythis Authority, namely:
`
`
`Rule 39.1{iv)
`PCT - Methods for treatment of the human or animal body by
`surgery
`
`
`
`
`Claims Nos.:
`becausethey relate to parts of the international Application that do not comply with the prescribed requirements to such
`an extent that no meaningful International Search can be carried out, specifically:
`
`
`Claims Nos.:
`
`

`
`Boxil Observations where unity of invention is lacking (Continuation of item 2 of first sheet)
`
`
`This International Searching Authority found multiple inventions in this international application, as follows:
`
`
`
`see additional sheet
`
`
` As all required additional search fees were timely paid by the applicant, this International Search Report coversail
`searchable claims.
`
`
` As all searchable claims could be searched without effort justifying an additional fee, this Authority did not invite payment
`of any additional fee.
`
` As only some of the required additional search fees were timely paid by the applicant, this international Search Report
`covers only those claims for which fees were paid, specifically claims Nos.:
`
`
` No required additional search fees were timely paid by the applicant. Consequently, this International Search Report is
`restricted to the invention first mentioned in the claims; it is covered by claims Nos.:
`
`
`
`
`
`Remark on Protest[| The additional search fees were accompanied by the applicant's protest.
` No pretest accompanied the paymentof additional search fees.
