Abstract

Surgical connection apparatus comprises a support having a proximal portion with a distal end and a proximal portion. The support forms a pathway between the proximal and distal portions. A plurality of self-closing clips are slidably disposed in the pathway and a pusher is arranged to slidably move in the pathway and push the clips in a distal direction. The apparatus facilitates partial ejection of a clip after which the remainder of the clip is withdrawn therefrom. In one embodiment, the support comprises a tubular needle with the distal end being pointed. The needle can be used to penetrate the tissue or material to be joined and to manipulate or approximate tissue or material to be joined before the clip is partially ejected.

Claims

1. Surgical connection apparatus comprising:

a tubular needle having a proximal portion and a distal portion with a pointed distal end, said tubular needle forming an interior pathway at least a portion of which being within said tubular needle between said proximal and distal portions;

a plurality of self-closing clips, each clip being slidably disposed in said pathway; and

a pusher having a portion arranged to slidably move in said at least a portion of said pathway and push and move said clips in a distal direction, including said pusher arranged to fully deploy a distal-most one of said clips from said distal end without movement of said needle relative to said pusher

wherein each clip has a first end and a second end, and both of said ends are ball shaped.

2. Surgical connection apparatus comprising:

a support having a distal portion having a distal end and a proximal portion, said support forming an interior pathway between said proximal and distal portions, said pathway being circumferentially closed along said distal portion and open at said distal end;

a plurality of self-closing clips, each clip being slidably disposed in said pathway;

a pusher having a portion arranged to slidably move in said pathway and push said clips in a distal direction; and

a stop member in contact with and extending from said distal portion of said support;

wherein said support comprises a tubular member, which forms at least a portion of said pathway, each clip has a memory set closed configuration, when said clips are disposed in said tubular member, said tubular member biases said clips away from said closed configuration, and when said clips are released from said tubular member, said clips move toward their memory set closed configuration, wherein each clip has a ball shaped first end and a ball shaped second end.

3. The apparatus of claim 2 wherein said support comprises a tubular member and said self-closing clips are slidably disposed in said tubular member and serially arranged.

4. The apparatus of claim 2 wherein said support distal portion is curved.

5. The apparatus of claim 2 wherein said support distal portion has a spiral portion.

6. The apparatus of claim 2 wherein said support member comprises a tubular member and said distal end is pointed.

7. The apparatus of claim 6 wherein said tubular member comprises a hypo-needle.

8. The apparatus of claim 7 wherein said hypo-needle has a slot formed therein, said slot extending toward said distal end of said support and said pusher having a portion extending through said slot.

9. The apparatus of claim 2 wherein said clips have a loop shaped memory set closed configuration.

10. The apparatus of claim 9 wherein said support comprises a tubular member and said self-closing clips are slidably disposed in said tubular member and serially arranged.

11. The apparatus of claim 2 wherein said distance ranges from about ⅛

inch to about 1 inch.

12. The apparatus of claim 2 wherein support comprises a tubular needle and said stop member extends radially from said needle.

13. The apparatus of claim 12 wherein said stop member is secured to said tubular needle.

14. The apparatus of claim 13 wherein said stop member is disk shaped.

15. The apparatus of claim 2 wherein said support comprises a tubular needle, at least a portion of said pathway is within said tubular needle, and said pusher has a portion arranged to slidably move in said at least a portion of said pathway and push said clips in a distal direction.

16. The apparatus of claim 2 wherein each clip is a discrete, separate element.

17. Surgical connection apparatus comprising:

a support having a distal portion having a distal end and a proximal portion, said support forming a pathway between said proximal and distal portions;

a plurality of self-closing clips, each clip being slidably disposed in said pathway; and

a pusher having a portion arranged to slidably move in said pathway and push said clips in a distal direction, said pusher having a first state where it is releasably locked in a first position in said support with one of said clips being in the distal portion of said support and a second state where it is releasably locked in a second position in said support with said one of said clips being partially ejected from said support;

wherein said support comprises a tubular member and said distal end is pointed;

wherein said tubular member comprises a hypo-needle;

wherein said hypo-needle has a slot formed therein, said slot extending toward said distal end of said support and said pusher extending through said slot; and

including a second tubular member surrounding a portion of said support and having a slot formed therein and aligned with said slot in said hypo-needle, said pusher extending through both slots;

wherein said second tubular member has a plurality of recesses and said pusher has a recess, further including a spring loaded button disposed in said pusher recess and said pusher being movable to align said spring loaded button with said second tubular member recesses.

18. Surgical connection apparatus comprising:

a tubular clip support having a distal portion having a distal end and a proximal portion, said support forming a pathway between said proximal and distal portions, said support having a slot formed therein;

a plurality of self-closing clips, each clip being slidably disposed in said pathway;

a tubular sleeve surrounding at least a portion of said tubular clip support and having a slot aligned with said slot in said tubular clip support; and

a pusher arranged to slidably move in said pathway and push said clips in a distal direction, said pusher extending through said slots;

wherein said pusher has a first state where it is releasably locked in a first position in said support with one of said clips being within the distal portion of said support and a second state where it is releasably locked in a second position in said support with said one of said clips being partially ejected from said support;

wherein said tubular sleeve has a plurality of recesses and said pusher has a recess, further including a spring loaded button being disposed in said pusher recess and said pusher being movable to align said spring loaded button with said tubular sleeve recesses.
