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

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.
