Abstract

A device for treating a tissue opening includes a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough; a pair of arms movably housed within the lumen of the capsule such that the pair of arms are movable between an open configuration and a closed configuration, the pair of arms being biased toward the open configuration such that when the pair of arms are moved distally with respect to the capsule, distal ends of the pair of arms are separated from one another to receive target tissue therebetween; a needle releasably connected to a first one of the pair of arms, the needle extending laterally inward toward a second one of the pair of arms and including a connecting structure extending along a portion thereof, the second one of the pair of arms including an opening located so that, when the pair of arms are moved to the closed configuration, the connecting structure of the needle engages the opening; and a suture extending from a portion of the needle proximally through the capsule.

First claim

1 - 15 . (canceled)

16 . A device for treating a tissue opening, comprising:
a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough; a pair of arms movably housed within the lumen of the capsule such that the pair of arms are movable between an open configuration and a closed configuration, the pair of arms being biased toward the open configuration such that when the pair of arms are moved distally with respect to the capsule, distal ends of the pair of arms are separated from one another to receive target tissue therebetween; a needle releasably connected to a first one of the pair of arms, the needle extending laterally inward toward a second one of the pair of arms and including a connecting structure extending along a portion thereof, the second one of the pair of arms including an opening located so that, when the pair of arms are moved to the closed configuration, the connecting structure of the needle engages the opening; and a suture extending from a portion of the needle proximally through the capsule.

17 . The device of claim 16 , wherein the needle is connected to the first one of the pair of arms via a frangible link designed to break when the connecting structure of the needle engages the opening and the needle disengages from the first arm when the pair of arms are moved to the open configuration.

18 . The device of claim 16 , wherein the connecting structure includes barbs.

19 . The device of claim 16 , wherein the opening of the second one of the pair of arms includes a barb feature and the connecting structure is a groove extending around a portion of the needle for receiving the barb feature.

20 . The device of claim 16 , further comprising:
a control member connected to the pair of arms for moving the pair of arms between the open configuration and the closed configuration.

21 . The device of claim 20 , further comprising:
a handle assembly connected to the capsule via a flexible member which is releasably coupled to the capsule, the control member extending through the flexible member to the handle assembly.

22 . The device of claim 16 , further comprising:
a locking mechanism for locking the pair of arms in the capsule in the closed configuration.

23 . The device of claim 22 , wherein, when the pair of arms are locked within the capsule, the suture becomes wedged so that it is restrained from distal translation.

24 . The device of claim 23 , further comprising:
a cutting feature cutting a portion of the suture extending proximally of a wedged portion of the suture.

25 . A device for closing a tissue opening, comprising:
a clip including a pair of arms movable between an open configuration in which distal ends of the pair of arms are separated from one another to receive target tissue therebetween and a closed configuration in which the pair of arms drawn toward one another to grip the target tissue therebetween; a needle releasably connected to a first one of the pair of arms, the needle extending laterally inward toward a second one of the pair of arms and including a connecting structure extending along a portion thereof, the second one of the pair of arms including an opening extending laterally therethrough located so that, when the pair of arms are moved to the closed configuration, the connecting structure of the needle engages the opening, the being frangible link designed to disengage when the pair of arms are moved to the open configuration after the connecting structure of the needle has engaged the opening; and a suture extending from a portion of the needle proximally through a portion of the device.

26 . The device of claim 25 , further comprising:
a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough, the lumen slidably receiving proximal ends of the pair of arms, the pair of arms being biased toward the open configuration such that moving the pair of arms distally with respect to the capsule permits distal ends of the pair of arms to separate from one another, in the closed configuration, the pair of arms being drawn proximally into the capsule so that contact with the capsule draws the pair of arms into the closed configuration.

27 . The device of claim 26 , further comprising:
a control member connected to the pair of arms for moving the pair of arms between the open configuration and the closed configuration; and a handle assembly connected to the capsule via a flexible member which is releasably coupled to the capsule, the control member extending through the flexible member to the handle assembly.

28 . The device of claim 26 , further comprising:
a locking mechanism for locking the pair of arms in the closed configuration.

29 . The device of claim 28 , wherein, when the pair of arms are locked within the capsule, the suture becomes wedged so that it is restrained from distal translation

30 . The device of claim 29 , further comprising:
a cutting feature cutting a portion of the suture extending proximally of a wedged portion of the suture.

31 . A method for treating a tissue opening, comprising:
inserting a clip to a target area within a patient body, the clip including a pair of arms movable between an open configuration in which distal ends of the pair of arms are separated from one another and a closed configuration in which distal ends of the pair of arms are drawn toward one another to grip tissue received therebetween, and a needle releasably connected to a first one of the pair of arms, the needle extending toward a second one of the pair of arms; positioning the pair of arms over a first portion of tissue along a tissue opening with the clip in the open configuration such that the first portion of tissue is received between the distal ends of the pair of arms; moving the pair of arms to the closed configuration such that the needle pierces the first portion of tissue and engages an opening extending laterally through a second one of the pair of arms; and moving the pair of arms to the open configuration such that the frangible link breaks, the needle remains engaged to the opening of the second one of the pair of arms and a suture extending proximally from a portion of the needle is threaded through the first portion of tissue.

32 . The method of claim 31 , further comprising:
after moving the pair of arms to the open configuration with the suture passed through the first portion of tissue, positioning the pair of arms over a second portion of tissue along the tissue opening substantially opposing the first portion with the clip in the open configuration with the second portion of tissue is received between the distal ends of the pair of arms; moving the pair of arms to the closed configuration such that the pair of arms grip the second portion of tissue between distal ends of thereof.

33 . The method of claim 32 , further comprising:
pulling the suture proximally relative to the clip to draw the first portion of tissue toward the second portion of tissue.

34 . The method of claim 33 , further comprising:
locking the clip in the closed configuration.

35 . The method of claim 34 , wherein locking the clip includes locking the suture relative to the clip and cutting a portion of the suture extending proximally from the clip.
