1. A vascular suturing device comprising:
- a) an elongated tubular body defining opposed proximal and distal end portions and having a longitudinal axis extending therethrough, the body including an inner tubular member, an outer tubular member and a central tubular member disposed between the inner and outer tubular members, the inner tubular member and the central tubular member mounted for movement relative to the outer tubular member about the longitudinal axis of the tubular body, and wherein;
i) the inner tubular member has an arcuate channel formed at the distal end thereof for carrying a pair of arcuate suture needles in back-to-back orientation within a plane extending generally perpendicular to the longitudinal axis of the body;
ii) the central tubular member has a distal driving stem extending into the arcuate channel of the inner tubular member and positioned between the pair of suture needles for sequentially driving the suture needles from the arcuate channel of the inner tubular member upon rotation of the central tubular member relative to the inner tubular member; and
iii) the outer tubular member has an arcuate channel formed at the distal end thereof for receiving the pair of arcuate suture needles after the suture needles have been sequentially driven from the arcuate channel of the inner tubular member by the driving stem of the central tubular member; and
b) an actuator operatively associated with the proximal end portion of the tubular body for effectuating the relative movement of the inner tubular member and the central tubular member relative to the outer tubular member so as to cause sequential passing of the suture needles from the arcuate channel of the inner tubular member to the arcuate channel of the outer tubular member.

Abstract
A vascular suturing device is disclosed which includes an elongated tubular body defining opposed proximal and distal end portions and having a longitudinal axis extending therethrough, the body including an inner tubular member, an outer tubular member and a central tubular member disposed between the inner and outer tubular members. The inner tubular member and the central tubular member are mounted for movement relative to the outer tubular member about the longitudinal axis of the body for sequentially driving a pair of suture needles through the wall of a blood vessel to close an incision formed therein.

18. A method of suturing comprising the steps of:
-
a) positioning a distal end portion of an elongated tubular body having a longitudinal axis extending therethrough adjacent an incision in a wall of a blood vessel, the body including a first tubular member and a second tubular member, the first tubular member mounted for movement relative to the second tubular member about the longitudinal axis of the tubular body, and carrying first and second suture needles connected to one another by an elongated suture;
b) passing the first suture needle from the first tubular member, through the wall of the blood vessel, to the second tubular member;
c) passing the second suture needle from the first tubular member, through the wall of the blood vessel, to the second tubular member; and
d) withdrawing the elongated tubular body from the wall of the blood vessel. - View Dependent Claims (19, 20)
