Abstract

A suture-based vessel closure device can perform the dilation of an arteriotomy puncture and does not require previous dilation of the arteriotomy puncture by a separate device or by a procedural sheath dilator. 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 hemostasis to the access site.

First claim

1 . A method of performing a procedure on a vascular or cardiac structure comprising:
inserting a first sheath into the common carotid artery through an arteriotomy in the wall of the common carotid artery; inserting at least one therapeutic device through the sheath to a treatment site, performing a therapeutic procedure, and removing the at least one therapeutic device from the sheath; inserting a suture delivery device into the common carotid artery through the arteriotomy; drawing at least one end of a suture outside the body of the patient using the suture delivery device such that the suture can be held until such time as the suture is to be tied off to create a permanent closure of the arteriotomy; removing the suture delivery device; and tying off the ends of the suture to close the arterial access site.

2 . A method as in claim 1 , further comprising the step of occluding the common carotid artery.

3 . A method as in claim 2 , wherein the first sheath includes a Y-arm connection to a flow line and further comprising the step of connecting the sheath to a reverse flow shunt.

4 . A method as in claim 1 , wherein the first sheath includes a detachable proximal extension tube, and further comprising the step of removing the proximal extension tube prior to inserting the suture delivery device.

5 . A method as in claim 11 , further comprising actuating a vessel wall locator for a first position which is generally in line with the elongate body to a second position which is generally extended away from said body.

6 . A method as in claim 1 , further comprising:
advancing a needle in a proximal to distal direction along at least a portion of the elongate body toward the arm, the needle being advanced through tissue of the common carotid artery; engaging a portion of the needle with the portion of the suture; and retracting the needle in a distal to proximal direction to draw the suture through the tissue.

7 . A method as in claim 1 , wherein the therapeutic device is a prosthetic aortic valve and the therapeutic procedure is transcatheter aortic valve implantation

8 . A method as in claim 1 , wherein the suture delivery device is inserted into the common carotid artery through the arteriotomy in exchange for the sheath.
