Method and device for suture manipulation
The invention relates to a suture manipulation device. The suture manipulation device includes a body and a snare. The snare is operatively connected to the body and is adapted to protract from the body, and after protracting from the body, rotate independent of the body. The snare is further adapted to ensnare a portion of suture passed through tissue while rotating, and secure the portion of the suture.
1. A suture manipulation device comprising:
a body;
a snare operatively connected to the body and adapted to:
protract from the body through an opening in the body;
ensnare a portion of suture passed through tissue;
secure the portion of the suture; and
wherein the snare includes, at a distal end, a hook; and
a slot located distally in the body and adapted to receive the hook to prevent the snare from retracting into the body through the opening in the body, wherein the slot is separate and distinct from the opening in the body.
2. The suture manipulation device of claim 1 , wherein the body has a length and comprises:
a shaft located inside the body and running proximally along the length of the body; and
a needle at a distal end of the body adapted to:
secure the portion of the suture;
pierce the tissue; and
release, after piercing the tissue, the portion of the suture.
3. The suture manipulation device of claim 2 , wherein the needle is curved.
4. The suture manipulation device of claim 2 , wherein the needle releases the portion of the suture before the portion of the suture is ensnared by the snare.
5. The suture manipulation device of claim 2 , wherein the needle comprises an angled slot forming a cavity large enough to allow the portion of the suture to pass.
6. The suture manipulation device of claim 2 , wherein the slot is located at a distal end of the needle.
7. The suture manipulation device of claim 1 , wherein the snare comprises a wire having a thickness and a bend proximal to the hook.
8. The suture manipulation device of claim 1 wherein the hook is substantially retracted into the slot when securing the portion of the suture.
9. The suture manipulation device of claim 8 , wherein the slot is located along the length of the body.
10. The suture manipulation device of claim 1 , wherein the snare is further adapted to rotate, after protracting from the body, independent of the body and to ensnare the portion of suture passed through tissue while rotating.
