Apparatus and method for positive closure of an internal tissue membrane opening
First Claim
1. A method for closure of an opening in a membrane of a blood vessel, the membrane having a distal side and proximal side, said method comprising:
- introducing at least two needles in a distal direction through an opening in the skin above the blood vessel opening;
advancing the two needles through the blood vessel membrane at two suture locations adjacent the blood vessel opening to form penetrations;
positioning suture material through the penetrations to span the opening in the blood vessel membrane; and
drawing the suture locations together with said suture material.

Abstract
The invention provides a device having two components: a needle advancing apparatus slidable longitudinally along a catheter to advance needles into a tissue membrane, such as a blood vessel wall, around an opening in the membrane; and, a suture retrieval assembly insertable through the catheter beyond a distal side of the tissue membrane. The needle advancing apparatus advances suture through the tissue wall. The suture retrieval assembly grabs the suture on the distal side of the tissue membrane for extraction thereof through the opening in the tissue membrane. A method for suturing a membrane beneath the patient'"'"'s skin is also disclosed.

7. A method for closure of an opening in a membrane of a blood vessel, the membrane having a distal side and a proximal side, said method comprising:
-
advancing a needle through an opening in the skin above the opening in the blood vessel membrane to penetrate the membrane adjacent the opening to form a first suture location; advancing a needle through the opening in the skin above the opening in the blood vessel membrane to penetrate the membrane adjacent the opening to form a second suture location; positioning suture material through the first and second penetrations to span the distal side of the blood vessel opening; drawing the suture locations together with said suture material. - View Dependent Claims (8, 9, 10, 11)

12. A method for closure of an opening in a membrane of a blood vessel, the membrane having a distal side and a proximal side, said method comprising:
-
introducing suture material through a first penetration in the blood vessel membrane adjacent to the opening therein; capturing a free end of the suture material; pulling the free end of the suture material through a second penetration in the blood vessel wall to span the distal side of the opening; and drawing the penetrations together with the suture material. - View Dependent Claims (13, 14, 15, 16)
