Method and apparatus for passing a suture
First Claim
1. A suture passing instrument comprising:
- an operation handle having at least one actuator movable between a first position and a second position and a slider mechanism operable by the actuator and including first and second pivotally attached slide members, the first slide member movable longitudinally along and inside a central cavity formed inside the handle body and the second slide member movable longitudinally along and inside a curved channel formed inside the handle body;
a needle member extending from the operation handle, the needle member having a curved end portion with a distal end and defining an eyelet extending therethrough at the distal end of the curved end portion wherein the needle member is cannulated and includes an interference member movable within the needle member to lock the suture within the eyelet; and
a suture holder assembly extending from the operation handle and being external to the needle member, the suture holder assembly has a movable suture carrier at a distal end configured to hold a suture, the movable suture carrier having a suture pusher telescopically and movably received in the movable suture carrier, wherein the suture carrier is movable between a retracted position and an extended position, wherein the suture pusher is movable beyond the suture carrier to carry the suture from outside the needle member and through the eyelet transversely to the distal end of the needle member.

Abstract
A suture passing instrument including an operation handle, a needle member, and a suture holder assembly. The operation handle has at least one actuator movable between a first position and a second position. The needle member extends from the operation handle. The needle member has a curved end portion and defines an eyelet extending therethrough. The suture holder assembly extends from the operation handle and has a movable suture carrier at a distal end configured to hold a suture. The movable suture carrier has a suture pusher telescopically and movably received in the movable suture carrier. The suture carrier is movable between a retracted position and an extended position. The suture pusher is movable beyond the suture carrier to carry the suture through the eyelet.

15. A suture passing instrument comprising:
-
an operation handle having an actuator movable between a first position and a second position; a cannulated needle member having an internal bore and extending from the operation handle, the needle member having a straight portion along a first longitudinal axis, a curved end portion extending from the straight portion and defining an eyelet extending therethrough at the distal end of the curved end portion; and a suture holder assembly extending from the operation handle, the suture holder assembly has a movable suture carrier at a distal end configured to hold a suture, the movable suture carrier having a suture pusher telescopically and movably received in the movable suture carrier along a second longitudinal axis parallel to the first longitudinal axis and outside the bore of the needle member, wherein the suture carrier is movable between a retracted position and an extended position, wherein the suture pusher is movable beyond the suture carrier to carry the suture through the eyelet of the needle member; and a flexible longitudinal interference member received within the internal bore of the cannulated needle member and movable from a retracted position in the straight portion to an extended position in the curved end portion to lock the suture within the eyelet of the needle member. - View Dependent Claims (16, 17, 18, 19, 20)

21. A suture passing instrument comprising:
-
an operation handle having a handle body, an actuator received in the handle body and movable between a first position and a second position and a slider mechanism operable by the actuator and including first and second pivotally attached slide members, the first slide member movable longitudinally along and inside a central cavity formed inside the handle body and the second slide member movable longitudinally along and inside a curved channel formed inside the handle body; a cannulated needle member having an internal bore and extending from the operation handle, the needle member having a straight portion along a first longitudinal axis, a curved end portion extending from the straight portion and defining an eyelet extending therethrough at the distal end of the curved end portion; a suture holder assembly extending from the operation handle, the suture holder assembly has a movable suture carrier at a distal end configured to hold a suture, the movable suture carrier having a suture pusher telescopically and movably received in the movable suture carrier along a second longitudinal axis parallel to the first longitudinal axis and outside the bore of the needle member, wherein the suture carrier is movable between a retracted position and an extended position, wherein the suture pusher is movable beyond the suture carrier to carry the suture through the eyelet of the needle member; and
an interference member movable within the cannulated needle member to retain the suture within the eyelet. - View Dependent Claims (22, 23)
