Abstract

A closure device for closing an opening in tissue is provided. The closure device includes an elongate member through which needles may be deployed. The closure device also includes a foot portion having one or more feet slidably mounted relative thereto. The feet are movable between a deployed position and a delivery position. The feet include cuffs removably mounted therein, with sutures connected between the cuffs. When the feet are in the deployed position and the needles are advanced, the needles securely engage the cuffs and draw the cuffs and suture through the lumen wall so that the opening in the lumen wall can be closed with the sutures.

Claims

1. A device for closing an opening in a body lumen, comprising:

an elongate member having a plurality of needle lumens;

a plurality of needles disposed within and advanceable from the plurality of needle lumens, a proximal end of the plurality of needles being mounted to a housing having a first portion and a second portion, the first portion and the second portion being separable to separate a first plurality of needles of the plurality of needles from a second plurality of needles of the plurality of needles;

a foot portion disposed distal a distal end of the plurality of needle lumens, the foot portion having a central axis; and

a plurality of feet slidably mounted on the foot portion and slidable both proximally along a length of the foot portion and radially away from the central axis of the foot portion, each foot of the plurality of feet having a cuff removably mounted therein.

2. The device as recited in claim 1, wherein a length of suture connects pairs of cuffs.

3. The device as recited in claim 1, wherein each foot of the plurality of feet being slidable between a delivery position and a deployed position.

4. The device as recited in claim 3, wherein each foot is slidable proximally along the length of the foot portion and radially away from the central axis of the foot portion when moving from the delivery position to the deployed position.

5. The device as recited in claim 1, further comprising a track and a track guide that facilitates movement of the plurality of feet.

6. The device as recited in claim 5, wherein the track guide is angled relative to the central axis of the foot portion.

7. The device as recited in claim 1, wherein the foot portion comprises an actuator lumen extending at least partially therethrough.

8. The device as recited in claim 1, wherein the plurality of needles comprise at least one needle having a shaft and a plurality of needle tips extending from a distal end of the shaft.

9. The device as recited in claim 1, further comprising a plunger operatively associated with the plurality of needles, wherein distal movement of the plunger advances the plurality of needles from the plurality of needle lumens.

10. A device for closing an opening in a body lumen, comprising:

an elongate member having a proximal end, a distal end, a central passage and a plurality of needle lumens extending from the proximal end toward the distal end;

a plurality of needles disposed within and advanceable from the plurality of needle lumens;

a foot portion disposed at the distal end of the elongate member, the foot portion having a central axis;

a plurality of feet slidably mounted on the foot portion, each foot of the plurality of feet being slidable between a delivery position and a deployed position, the plurality of feet moving both proximally along a length of the foot portion and radially away from the central axis of the foot portion when moving from the delivery position to the deployed position, each foot of the plurality of feet having a cuff removably mounted therein, with a length of suture being connected between each pair of cuffs; and

a track and track guide system that facilitates movement of the plurality of feet between the delivery and deployed positions, the foot portion includes a plurality of track guides and each foot includes a track.

11. The device as recited in claim 10, wherein the plurality of track guides are angled relative to the central axis of the foot portion, an angled configuration of the track guides facilitating radial movement of the plurality of feet.

12. The device as recited in claim 10, wherein the foot portion comprises an actuator lumen extending at least partially therethrough.

13. The device as recited in claim 12, further comprising an actuator extending through the central passage and the actuator lumen, the actuator being operatively associated with the plurality of feet such that proximal movement of the actuator causes the plurality of feet to move from the delivery position to the deployed position.

14. The device as recited in claim 10, wherein the plurality of needles comprise at least one needle having a shaft and a plurality of needle tips extending from a distal end of the shaft.

15. The device as recited in claim 10, further comprising a plunger operatively associated with the plurality of needles, wherein distal movement of the plunger causes the plurality of needles to advance from the plurality of needle lumens and engage the cuffs when the plurality of feet are in the deployed position.
