Apparatus for suturing a blood vessel
First Claim
1. A suturing device comprising:
- a) an inner tubular member having an arcuate channel formed at a distal end thereof for carrying a pair of arcuate suture needles in back-to-back orientation;
b) a central tubular member having a distal driving stem extending into the channel of the inner tubular member and positioned between the pair of suture needles for sequentially driving the suture needles from the channel of the inner tubular member upon rotation of the central tubular member relative to the inner tubular member; and
c) an outer tubular member having a channel formed at a 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.

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. A vascular dilator having a tapered distal tip portion is supported within the inner tubular member and is dimensioned to extend beyond the distal end of the inner tubular member for positioning the suturing device at the incision in the wall of the blood vessel. The dilator is configured to direct blood flow from the distal portion of the dilator to a location remote from the blood vessel for observation to confirm the location of the device.
