Abstract

A suturing system including a sheath, a handle assembly proximal the sheath, an elongate body disposed between the sheath and the handle, a plurality of needles disposed distal the elongate body in a pre-deployed configuration and movable into the elongate body in a deployed configuration, each of the plurality of needles including a needle tip, each needle tip being orientated proximally towards the elongate body in the pre-deployed configuration, and a needle capture assembly disposed between a distal end of the elongate body and the handle, the needle capture assembly including two needle engaging edges longitudinally spaced with respect to each other, with each being configured to interlock with at least one of the plurality of needles.

First claim

What is claimed is:

1 . A suturing system comprising:
an elongate body; a needle disposed distal the elongate body in a pre-deployed configuration, the needle comprising a needle tip being orientated proximally towards a handle disposed proximal the elongate body; a needle capture assembly disposed between a distal end of the elongate body and the handle, the needle capture assembly comprising two needle engaging edges longitudinally spaced with respect to each other; and a suture attached to at least one of the two needles.

2 . The suture system of claim 1 , wherein each needle comprises a distally facing surface configured to interlock with one of the two needle engaging edges.

3 . The suture system of claim 1 , wherein one of the two needles comprises a notch configured to interlock with one of the two edges.

4 . The suture system of claim 1 , further comprising two slots longitudinal spaced with respect to each other.

5 . The suturing system of claim 4 , wherein one of the two needle engaging edges is associated with one of the two slots.

6 . The suturing system of claim 1 , wherein the needle capture assembly comprises a distal guide configured to direct one of the two needles towards one of the two needle engaging edges.

7 . The suturing system of claim 1 , wherein the needle capture assembly comprises a distal guide configured to direct one of the two needles towards both of the two needle engaging edges.

8 . The suturing system of claim 1 , wherein comprises a needle receptacle configured to receive and direct one of the two needles towards one of the two needle engaging edges.

9 . The suturing system of claim 1 , further comprising a central aperture extending through the needle capture assembly, the central aperture to receive an elongate member.

10 . A suturing system comprising:
a sheath; a handle assembly proximal the sheath; an elongate body disposed between the sheath and the handle; a plurality of needles disposed distal the elongate body in a pre-deployed configuration and movable into the elongate body in a deployed configuration, each of the plurality of needles comprising a needle tip, each needle tip being orientated proximally towards the elongate body in the pre-deployed configuration; and a needle capture assembly disposed between a distal end of the elongate body and the handle, the needle capture assembly comprising two needle engaging edges longitudinally spaced with respect to each other, with each being configured to interlock with at least one of the plurality of needles.

11 . The suturing system of claim 10 , wherein the needle capture assembly comprises a plurality of distal guides configured to direct the plurality of needles towards the two needle engaging edges.

12 . The suturing system of claim 11 , wherein a second guide is disposed between the needle engaging edges.

13 . The suturing system of claim 10 , wherein the needle capture assembly comprises a distal guide to direct one of the plurality of needles towards the two needle engaging edges, the needle selectively cooperating with each of the two needle engaging edges.

14 . The suturing system of claim 10 , wherein the needle capture assembly comprises a body having a peripheral surface formed, at least in part, from the two needle engaging edges.

15 . The suturing system of claim 14 , wherein each needle engaging edge forms less than a complete generally circumferential periphery surface of the body.

16 . The suturing system of claim 10 , further comprising a plurality of slots, each slot being associated with one of the two needle engaging edges.

17 . The suturing system of claim 16 , further comprising a securing material filling the plurality of slots.

18 . The suturing system of claim 10 , wherein one needle tip is proximal a proximal-most needle engaging edge of the two needle engaging edges in the deployed configuration.

19 . A suturing system comprising:
a sheath; a handle assembly proximal the sheath; an elongate body disposed between the sheath and the handle; a plurality of needles disposed distal the elongate body in a pre-deployed configuration and movable into an interior of the elongate body in a deployed configuration, each of the plurality of needles comprising a needle tip, each needle tip being orientated proximally towards the elongate body in the pre-deployed configuration; and a needle capture assembly disposed between a distal end of the elongate body and the handle, the needle capture assembly comprising a plurality of engaging edge segments, wherein the plurality of engaging edge segments comprise two longitudinally spaced engaging edge segments and two circumferentially spaced engaging edge segments, each engaging edge segment being configured to interlock with at least one of the plurality of needles.

20 . The suturing system of claim 19 , wherein one engaging edge segment is both one of the two longitudinally spaced engaging edge segments and one of the two circumferentially spaced engaging edge segments.
