Wound closure apparatus and method for its use
First Claim
1. A surgical apparatus for closing an incision or wound in a vessel wall within a living patient, the apparatus comprising:
- a tubular member dimensioned for insertion within an incision, said tubular member having a proximal end and a distal end and a center lumen extending longitudinally through said tubular member from said proximal end to said distal end;
a mesh assembly including an expandable portion, said mesh assembly dimensioned for insertion within said center lumen of said tubular member to reversibly position said expandable portion through an incision or wound into a vessel within a living patient, said expandable portion constructed to be configured between an expanded condition and a collapsed condition;
first and second side lumens longitudinally disposed along opposing sides of said center lumen and extending along said tubular member, each said side lumen dimensioned to receive a piercing element therein;
a pair of tubular piercing elements dimensioned to be slidably received within said side lumens, said piercing elements each having a pointed end capable of piercing the wall of a vessel to deliver first and second sutures within the vessel through the wall thereof.

Abstract
A wound closure apparatus and a method for its use are described. The apparatus includes a trilumen tubular member dimensioned to be positioned within a blood vessel through a conventional catheter sheath introducer. A mesh assembly extends longitudinally through the center lumen of the tubular member to position an expandable mesh portion within the vessel. The expandable mesh portion can be configured between a collapsed condition and an expanded condition by the attending surgeon or other medical personnel. Sutures are deposited into the blood vessel by a pair of medical needles inserted through the vessel wall adjacent the wound so that the leading ends of the sutures are deposited directly into the expandable mesh portion and are captured therein. The leading ends of the sutures can be withdrawn from the vessel through the center lumen of the trilumen body and pulled outside of the wound area where the surgeon can tie the ends thereof to close and seal the vessel wound.

9. A surgical apparatus for closing an incision or wound in a vessel wall within a living patient, the apparatus comprising:
-
a tubular member dimensioned for insertion within an incision, said tubular member having a proximal end and a distal end and a center lumen extending longitudinally through said tubular member from said proximal end to said distal end; a mesh assembly including an expandable portion, said mesh assembly dimensioned for insertion within said center lumen of said tubular member to reversibly position said expandable portion through an incision or wound into a vessel within a living patient, said expandable portion constructed to be configured between an expanded condition and a collapsed condition; first and second piercing members associated with said tubular member, each said piercing member having a proximal end and a distal end with a lumen extending therethrough, said distal end having a piercing point thereon to penetrate the wall of a vessel to deliver a suture through said piercing member lumen and within said vessel through said wall thereof. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for closing an incision or wound in a vessel wall within a living patient, comprising:
-
providing a tubular member having a proximal end and a distal end thereon with a center lumen extending through said tubular member from said proximal end to said distal end; inserting said distal end of said tubular member into a wound or incision within the wall of a vessel; advancing an expandable mesh through said center lumen past said distal end of said tubular member and within said vessel, said mesh constructed to be configured between a longitudinally collapsed condition and an expanded condition wherein at least a portion of said mesh is substantially perpendicular to the longitudinal axis of said tubular member; configuring said expandable mesh in said expanded condition; delivering first and second sutures within said vessel by injecting the leading ends thereof through the wall of said vessel adjacent said incision or wound; capturing said leading ends of said sutures within said expandable mesh; and withdrawing said expandable mesh and said leading ends of said sutures from said vessel through said wound and said center lumen of said tubular member so that said sutures are threaded first through said vessel wall adjacent said wound, into said vessel and exiting from said vessel through said wound to thereby be positioned outside of the body of a living patient where said sutures can be tied to close and seal said wound. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
