Vessel wound closure device
First Claim
Patent Images
1. A vessel wound closure device for use with a vessel wound comprising:
- a sheath having a proximal end and a distal end;
a first hollow vessel penetrating member associated with the sheath and a second hollow vessel penetrating member associated with the sheath, wherein the first and second vessel penetrating members are movable from a first position to a second position beyond the distal end of the sheath to penetrate through a vessel wall adjacent the vessel wound;
a suture slidably housed within the first hollow vessel penetrating member; and
a single filament snare loop slidably housed within the second hollow vessel penetrating member, wherein the snare loop is positionable to capture the suture when the first and second vessel penetrating members are in the second position.

Abstract
A vessel wound closure device that separately deploys a suture and a snare within a vessel to produce a stitch across a puncture site of a vessel. Once deployed within the vessel, the suture is captured within the snare, withdrawn, and then secured to provide a stitch across the puncture site of the vessel. The vessel wound closure device minimizes the amount of material introduced or left within the vessel or between edges of the puncture site, maximizes healing of the puncture site, and renders the vessel amenable to subsequent interventional or therapeutic procedures at or near the same site.

12. A method for closing a vessel wound in a vessel of a patient, the method comprising:
-
deploying a first hollow vessel penetrating member and a second hollow vessel penetrating member through a vessel wall and into the vessel adjacent the vessel wound;
deploying a suture from the first hollow vessel penetrating member;
deploying a single filament snare loop from the second hollow vessel penetrating member; and
capturing the suture within the single filament snare loop within the vessel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A vessel wound closure device comprising:
-
a sheath having a proximal end and a distal end;
a thumb grip between the proximal end and the distal end of the sheath;
the sheath extending distally from the thumb grip and having a first exit port, a second exit port, and a movable stabilizer foot at a distal end thereof;
a first hollow vessel penetrating member extending through the sheath;
a second hollow vessel penetrating member extending through the sheath;
a slidable suture extending through the first hollow vessel penetrating member;
a slidable snare loop extending through the second hollow vessel penetrating member; and
a first rail extending proximally from the thumb grip, the first rail having a first slide mounted thereon for regulating movement of the first hollow vessel penetrating member and a second slide mounted thereon for regulating movement of the suture. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A method of closing a vessel wound in a vessel, the method comprising:
-
deploying a first hollow vessel penetrating member and a second hollow vessel penetrating member through a vessel wall and into the vessel adjacent the vessel wound;
deploying a suture into the vessel from the first hollow vessel penetrating member;
deploying a snare loop into the vessel from the second hollow vessel penetrating member; and
capturing the suture within the snare loop. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
