Suture Delivery Device

摘要

A suture-based vessel closure device is configured to close a carotid artery puncture site. The suture-based vessel closure device can place one or more sutures across the vessel access site such that, when the suture ends are tied off after sheath removal, the stitch or stitches provide hem ostasis to the access site. The sutures can be applied either prior to insertion of a procedural sheath through the arteriotomy or after removal of the sheath from the arteriotomy.

主权项

1. A device for closing an aperture in a wall of a blood vessel, the device comprising:
a body having a distal tip sized and shaped to be inserted through an arteriotomy into an artery; at least one suture element held within the body; and at least one suture capture rod within the body, the suture capture rod being operatively associated with the suture element and arranged to pass the suture element through the vessel wall such that opposed portions of the suture element extend from the vessel wall and the suture element defines a knot between opposed portions thereof after the suture element has been passed through the vessel wall; and; a guidewire lumen located in the distal tip, wherein the guidewire lumen forms a first opening at a distalmost end of the distal tip and a second opening located between the distalmost end and a vessel wall locator device that positions against a blood vessel when the device is in use.
