Abstract

A device for closing an opening in tissue includes a shaft having a proximal end, a distal end, and a channel disposed between the proximal and distal ends. A pair of pins are disposed within the channel and cooperate with a slidable and axially movable foot. The foot extends distally from the channel with a flexible guidebody extending from a distal foot end of the foot.

Claims

1. A device for closing an opening in tissue, the device comprising:

a shaft having a proximal end, a distal end, and a channel disposed between said proximal end and said distal end and extending proximally from said distal end of said shaft;

a foot received within said channel, said foot having a proximal foot end and a distal foot end, a portion of said foot being longitudinally slidable within the channel and being laterally movable with respect to said shaft such that the proximal foot end extends laterally beyond the channel of the shaft; and

a flexible guidebody extending from said distal foot end of said foot.

2. The device of claim 1, wherein said foot is axially movable within said channel.

3. The device of claim 1, further comprising needles slidably disposed within the shaft and needle receptacles formed in said foot, said needle receptacles being adapted to receive said needles.

4. The device of claim 1, wherein said guidebody extends from said shaft at a fixed angle.

5. The device of claim 1, wherein said foot is separate from said shaft and being axially moveable with respect to said shaft.

6. A device for closing an opening in tissue, the device comprising:

a shaft having a proximal end, a distal end, and a channel disposed between said proximal end and said distal end and extending proximally from said distal end of said shaft;

a pair of pins disposed within said channel;

a foot slidingly received within said channel and cooperating with said pair of pins, said foot having a proximal foot end and a distal foot end, said foot being movable with respect to said shaft; and

a flexible guidebody coupled to and extending directly from said distal foot end of said foot.

7. The device of claim 6, wherein said foot is axially movable within said channel and is pivotally mounted to said pair of pins.

8. The device of claim 7, further comprising an actuation wire coupled to said foot, said foot being moveable via motion of an actuation wire.

9. The device of claim 6, further comprising needles slidably disposed within the shaft and needle receptacles formed in said foot, said needle receptacles being adapted to receive said needles.

10. The device of claim 6, wherein said foot includes a slot configured to cooperate with said pair of pins.

11. The device of claim 10, wherein said foot slides relative to said shaft and said pair of pins.

12. The device of claim 6, wherein said foot is separate from said shaft and being axially moveable with respect to said shaft.

13. A device for closing an opening in tissue, the device comprising:

a shaft having a proximal end, a distal end, and a channel disposed between said proximal end and said distal end and extending proximally from said distal end of said shaft;

a pair of pins disposed within said channel;

a separate foot slidingly received within said channel and cooperating with said pair of pins, said foot having a proximal foot end and a distal foot end, said proximal foot end cooperating with said pair of pins and said distal foot end extending distally from said channel; and

a flexible guidebody directly attached to and extending from said distal foot end of said foot.

14. The device of claim 13, said distal foot end including an attachment member, said flexible guidebody being mounted to said attachment member and extending distally from said attachment member.

15. The device of claim 14, wherein said foot is slidably and axially movable to said pair of pins.

16. The device of claim 15, further comprising an actuation wire coupled to said foot, said foot being moveable via motion of an actuation wire.

17. The device of claim 16, further comprising needles slidably disposed within the shaft and needle receptacles formed in said foot, said needle receptacles being adapted to receive said needles.

18. The device of claim 17, wherein said guidebody extends from said shaft at a fixed angle.

19. The device of claim 17, wherein said shaft includes a bend adjacent said guide-body.

20. The device of claim 18, wherein said needle receptacle includes a cuff coupled to a link.
