Abstract
Abstract A graft attachment device having an elongated body with a leading end and a trailing end, each defining an element for carrying a filament such as a suture. The body further defines at least one element for attaching to the body either a graft or a graft connection element which is in turn connected to the graft. The element for attaching enables the body to rotate relative to the graft from an initial insertion position, along an axis substantially parallel to the graft, to a final fixation position transverse to the graft to secure the graft relative to a bone.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
190 words
A graft attachment device for attaching an anterior cruciate ligament graft to a bone wherein a passage is drilled through the bone for attachment thereto, comprising: an elongated body sized to pass through the passage in the bone and having an upper surface, a lower surface, a leading end, and a trailing end, each said end having a hole defined by said elongated body configured to carry a filament, and said body further defining two adjacent openings for attaching to said body one of the graft and a graft connection element, said two adjacent openings being disposed between said hole in said leading end and said hole in said trailing end and enabling said body to rotate relative to the graft from an initial insertion position, along an axis substantially parallel to the graft, to a final fixation position transverse to the graft to secure the graft relative to the bone; filament releasably threaded through said holes defined in said leading end and said trailing end; and a graft connection element comprising a sling member, said sling member having a width sufficient to carry the graft during and after implantation.
Claim 2
Dependent Claim
190 words
A graft attachment device for attaching an anterior cruciate ligament graft to a bone wherein a passage is drilled through the bone for attachment thereto, comprising: an elongated body sized to pass through the passage in the bone and having an upper surface, a lower surface, a leading end, and a trailing end, each said end having a hole defined by said elongated body configured to carry a filament, and said body further defining two adjacent openings for attaching to said body one of the graft and a graft connection element, said two adjacent openings being disposed between said hole in said leading end and said hole in said trailing end and enabling said body to rotate relative to the graft from an initial insertion position, along an axis substantially parallel to the graft, to a final fixation position transverse to the graft to secure the graft relative to the bone; filament releasably threaded through said holes defined in said leading end and said trailing end; and a graft connection element comprising a sling member, said sling member having a width sufficient to carry the graft during and after implantation.
Claim 3
Dependent Claim
13 words
The graft attachment device of claim 1 in which said filament comprises suture.
Claim 4
Dependent Claim
19 words
The graft attachment device of claim 1 in which said sling member is a loop of polyester tape material.
Claim 5
Dependent Claim
49 words
The graft attachment device of claim 1 wherein said filament comprising a lead suture releasably connected to said hole defined in said leading end and a trailing suture releasably connected to said hole defined in said trailing end, said lead and trailing sutures being perceptibly different from one another.
Claim 6
Dependent Claim
20 words
The graft attachment device of claim 4 in which said lead suture has a larger diameter than said trailing suture.
Claim 7
Dependent Claim
25 words
The graft attachment device of claim 1 in which said elongated body is a rectangular, bar-shaped member with rounded longitudinal edges and curved end faces.
Claim 8
Dependent Claim
19 words
The graft attachment device of claim 1 in which said sling member has a width of about one-quarter inch.
Claim 9
Dependent Claim
177 words
A graft attachment device for attaching an anterior cruciate ligament graft to a bone wherein a passage is drilled through the bone for attachment thereto, comprising: a graft connection element comprising a sling member having a width sufficient to carry the graft during and after implantation; an elongated body sized to pass through the passage in the bone and having an upper surface, a lower surface, a leading end, and a trailing end, each said end having a hole defined by said elongated body configured to carry a filament, a portion of said body disposed between said hole in said leading end and said hole in said trailing end being configured for attaching to said body the graft connection element and enabling said body to rotate relative to the graft from an initial insertion position, along an axis substantially parallel to the graft, to a final fixation position transverse to the graft to secure the graft relative to the bone; and filament threaded through said hole in said leading end and said hole in said trailing end.
Claim 10
Dependent Claim
177 words
A graft attachment device for attaching an anterior cruciate ligament graft to a bone wherein a passage is drilled through the bone for attachment thereto, comprising: a graft connection element comprising a sling member having a width sufficient to carry the graft during and after implantation; an elongated body sized to pass through the passage in the bone and having an upper surface, a lower surface, a leading end, and a trailing end, each said end having a hole defined by said elongated body configured to carry a filament, a portion of said body disposed between said hole in said leading end and said hole in said trailing end being configured for attaching to said body the graft connection element and enabling said body to rotate relative to the graft from an initial insertion position, along an axis substantially parallel to the graft, to a final fixation position transverse to the graft to secure the graft relative to the bone; and filament threaded through said hole in said leading end and said hole in said trailing end.
Claim 11
Dependent Claim
19 words
The graft attachment device of claim 8 in which said sling member is a loop of polyester tape material.
Claim 12
Dependent Claim
23 words
The graft attachment device of claim 9 in which said portion of said body includes two adjacent openings defined in said elongated body.
Claim 13
Dependent Claim
19 words
The graft attachment device of claim 10 in which said sling member has a width of about one-quarter inch.
