Abstract

A device for closing an opening in tissue includes a shaft having a proximal end, a distal end, and at least one pin associated with a distal end the shaft. A flexible guidebody extends from the distal end of the shaft, while a foot associated with the device is movable with respect to the shaft through the pin connected to at least one slot of the foot. Another device for closing an opening in tissue includes a shaft having a proximal end and a distal end. A plurality of feet are disposed proximate the distal end of the shaft, the plurality of feet being movable with respect to the shaft. The device further includes a flexible guidebody extending from the distal end of the shaft.

Claims

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

a shaft having a proximal end and a distal end, said shaft having at least one pin;

a pivotable foot having a proximal foot end, a distal foot end, and at least one slot, said at least one slot being formed in a side of said pivotable foot and receiving said at least one pin at said distal end of said shaft, said foot being movable with respect to said shaft and said at least one slot being axially moveable with respect to said at least one pin, said at least one slot and said at least one pin cooperating to rotate and proximally displace said foot with said at least one pin moving toward a distal end of said at least one slot; and

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

2. The device of claim 1, wherein said foot is rotationally movable about said at least one pin.

3. The device of claim 1, wherein said foot is moveable via motion of an actuation wire.

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

a shaft having a proximal end and a distal end, said shaft having at least one pin;

a pivotable foot on said distal end of said shaft, said pivotable foot having a proximal foot end, a distal foot end, and at least one slot, said at least one slot being formed in a side of said pivotable foot and receiving said at least one pin at said distal end of said shaft, said pivotable foot being movable with respect to said shaft and said at least one slot being axially moveable with respect to said shaft, said pivotable foot having at least one receptacle, said at least one receptacle having at least one slot oriented with respect to a surface of the at least one receptacle; and

a flexible guidebody abutting and extending directly from said distal foot end of said pivotable foot.

5. The device of claim 4, wherein said at least one slot extends substantially tangentially to said surface of said at least one receptacle.

6. The device of claim 4, wherein said at least one slot extends laterally through said foot.

7. The device of claim 4, further comprising a movable flap disposed over said at least one slot.

8. The device of claim 7, wherein a portion of said movable flap is affixed along one side of said at least one slot and another portion of said movable flap flexing into said at least one receptacle to release a suture disposed within the slot.

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

a shaft having a proximal end and a distal end;

a foot proximate said distal end of said shaft, said foot having a proximal foot end, a distal foot end, and a slot, said slot being configured to facilitate slidablilty of the foot with respect to said shaft, said foot being axially moveable with respect to said shaft; and

a flexible guidebody extending from said distal foot end of said foot, wherein said flexible guidebody abuts and is directly connected to said distal foot end of said foot.

10. The device of claim 9, wherein said foot is oriented about a longitudinal axis of said shaft.

11. The device of claim 9, wherein said foot further comprises at least one cuff pocket.

12. The device of claim 9, wherein said foot further comprises a cam surface.

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

a shaft having a proximal end and a distal end, said shaft having at least one pin;

a pivotable first foot on said distal end of said shaft, said first foot having a proximal foot end, a distal foot end, and at least one slot, said at least one slot being formed in a side of said pivotable foot and receiving said at least one pin at said distal end of said shaft, said pivotable foot being movable with respect to said shaft and said at least one slot being axially moveable with respect to said shaft, each of said proximal foot end and said distal foot end including a receptacle configured to receive a suture cuff, with said distal foot end having a generally tapered configuration, said receptacle oriented transverse to a longitudinal axis of said foot;

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

14. The device of claim 13, wherein first foot is pivotally associated with said shaft.
