Apparatus for vascular hole closure
First Claim
1. An apparatus for facilitating wound closure of an opening in tissue, which comprises:
- a) a handle portion dimensioned to be gripped by the hand of a user;
b) an elongate body portion connected to the handle portion and extending distally therefrom, the elongate body portion defining a longitudinal axis and having proximal and distal end portions;
c) a jaw mechanism including a stationary jaw affixed to the distal end portion of the elongate body portion and a movable jaw movably mounted to the distal end portion of the elongate body portion and movable between an initial closed position and a deployed open position;
d) a suture assembly including a length of suture supported by the jaw mechanism, the suture assembly at least partially positionable within the opening in the tissue;
e) first and second suture engaging members operatively associated with the stationary jaw and the movable jaw, respectively, the first and second suture engaging members engagable with end portions of the suture;
f) a deployment mechanism operable to move the movable jaw between the initial position and the deployed position; and
g) an actuator mechanism operatively associated with the first and second suture engaging members, the actuator mechanism configured to move the first and second suture engaging members from a first position remote from the free ends of the suture to a second position wherein the first and second suture engaging members engage respective end portions of the suture.

Abstract
An apparatus for facilitating wound closure of an opening in tissue includes a handle portion dimensioned to be gripped by the hand of a user, an elongate body portion connected to the handle portion and extending distally therefrom, a jaw mechanism including a stationary jaw affixed to the distal end portion of the elongate body portion and a movable jaw movably mounted to the distal end portion of the elongate body portion and movable between an initial closed position and a deployed open position, a suture assembly including a length of suture supported by the jaw mechanism, and being at least partially positionable within the opening in the tissue, first and second suture engaging members respectively operatively associated with the stationary jaw and the movable jaw, a deployment mechanism operable to move the movable jaw between the initial position and the deployed position, and an actuator mechanism operatively associated with the first and second suture engaging members and configured to move the first and second suture engaging members from a first position remote from the free ends of the suture to a second position wherein the first and second suture engaging members engage respective free ends of the suture. A method for facilitating closure of an opening in a tissue, e.g., a blood vessel wall is also disclosed.

11. An apparatus for facilitating closure of an opening in tissue, which comprises:
-
a handle; an elongate body extending distally from the handle, and having proximal and distal end portions, and defining a longitudinal axis; a jaw assembly mounted to the distal end of the elongate member and having a stationary jaw and a movable jaw, the movable jaw movable between an initial position adjacent the stationary jaw such that the stationary jaw and the movable jaw are configured to fit through an opening in tissue to a deployed position wherein the movable jaw is spaced apart from the stationary jaw, the stationary jaw and the movable jaw each defining a recess for receipt of an edge of tissue forming the opening in the tissue; a suture assembly mounted to the jaw assembly, the suture assembly including a length of suture having first and second suture end portions; and first and second suture engaging members movably mounted within the stationary and the movable jaw such that the first suture engaging member is movable to traverse the recess in the stationary jaw to engage the first suture end portion and the second suture engaging member is movable to traverse the recess in the movable jaw to engage the second suture end portion. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for facilitating closure of an opening in a tissue, comprising the steps of:
-
introducing an elongate body of a surgical apparatus through an opening in a tissue section such that a distal and portion of the surgical apparatus is disposed within a space behind the opening in the tissue section, the distal end portion including a stationary jaw and a movable jaw, the stationary and movable jaws supporting free ends of a length of suture thereon; moving a distal end of the movable jaw away from a distal end of the stationary jaw; advancing first and second suture engaging members operatively associated with the elongate body through opposed sides of the opening in the tissue section; engaging the first and second suture engaging members with respective free ends of the length of suture; retracting the first and second suture engaging members such that the free ends of the length of suture engaged by the first and second suture engaging members are drawn through the opposed edges of tissue and an intermediate portion of the length of suture extends across the opening; and securing the free end portions of the length of suture to facilitate closure of the opening.
