Abstract

A suture securing device includes a body with a distal end portion defining a suture receiving opening; a shaft and the body being assembled for relative reciprocal motion between a first position and a second position; and a tension coil spring operably attached to the body and operably attached adjacent a distal end portion of the shaft and disposed adjacent a suture receiving opening, When the body and shaft are in the first position, the tension coil spring is in a rest position, and when the body and/or the shaft are in the second position, the tension coil spring is in a tensioned position to form at least one gap therebetween to enable receipt of at least a portion of at least one suture.

wherein the suture securing device is configured and dimensioned such that, when said body and shaft are in the first position, the tension coil spring is in a rest position, and when at least one of the body and the shaft are in the second position, the tension coil spring is in a tensioned position at a point along a path defined by the relative reciprocal longitudinal motion of the tension coil spring to form at least one gap therebetween to enable receipt of at least a portion of at least one suture and

wherein relative reciprocal motion of the shaft with respect to the body effects the relative reciprocal motion between the first position and the second position.

2. The suture securing device according to claim 1, wherein the shaft and the body are assembled for relative reciprocal longitudinal motion between the first position, the second position and a third position.

3. The suture securing device according to claim 2, wherein the suture securing device is configured and dimensioned such that when the body and shaft are in the third position, the tension coil spring is in a position to enable securing of at least a portion of at least one suture by the tension coil spring.

4. The suture securing device according to claim 1, wherein the suture securing device is configured and dimensioned such that movement of at least one of the body and the shaft enables the coils of the coil spring to compress the at least one gap to enable the coils of the coil spring to grasp the at least a portion of at least one suture inserted within the at least one gap.

5. A suture securing device comprising:

a body having proximal and distal end portions, the distal end portion defining a suture receiving opening;

a shaft having proximal and distal end portions, the shaft at least partially disposed in the body, the shaft and the body being assembled for relative reciprocal longitudinal motion between a first position, a second position, and a third position;

a tension coil spring having a first end and a second end, the first end being operably attached to the distal end portion of the body and the second end being operably attached adjacent the distal end portion of the shaft, said tension coil spring disposed adjacent the suture receiving opening, said tension coil spring assembled for relative reciprocal longitudinal motion; and

a mounting member attached to the body, the first end of the tension coil spring being operably attached to the distal end portion of the body via the mounting member, the second end of the tension coil spring being operably attached to the distal end portion of the shaft via the mounting member,

wherein the suture securing device is configured and dimensioned such that, when said body and shaft are in the first position, the tension coil spring is in a rest position, and when at least one of the body and the shaft are in the second position, the tension coil spring is in a tensioned position at a point along a path defined by the relative reciprocal longitudinal motion of the tension coil spring to form at least one gap therebetween to enable receipt of at least a portion of at least one suture and

wherein relative reciprocal motion of the shaft or the body effects the relative reciprocal motion between the first position and the second position.

6. The suture securing device according to claim 5, wherein the suture securing device is configured and dimensioned such that when the body and shaft are in the third position, the tension coil spring is in a position to enable securing of at least a portion of at least one suture by the tension coil spring.

7. The suture securing device according to claim 6, wherein the suture securing device is configured and dimensioned such that movement of at least one of the body and the shaft extends the coils of the coil spring to form at least one gap therebetween that is sufficient to enable at least a portion of at least one suture to be inserted within the at least one gap.

8. The suture securing device according to claim 6, wherein the suture securing device is configured and dimensioned such that movement of at least one of the body and the shaft enables the coils of the coil spring to compress the at least one gap to enable the coils of the coil spring to grasp the at least a portion of at least one suture inserted within the at least one gap.

9. A suture securing device comprising:

a body having proximal and distal end portions, the distal end portion defining a suture receiving opening;

a shaft having proximal and distal end portions, the shaft at least partially disposed in the body, the shaft being longitudinally movable relative to the body between a first position and a second position; and
