[0055]Low Profile Guiding System

[0056]Specific embodiments of the present disclosure are now described with reference to the FIGS., where like reference numbers indicate identical or functionally similar elements. The present disclosure is directed to a device and method for closing an arteriotomy after a procedure in which a vessel was punctured to gain access to the vessel lumen. FIGS. 1-10 show cross-sectional views of body tissue 100 with a vessel 102 disposed therein. FIG. 1 shows a procedural device 108, such as a balloon catheter, disposed partially within a lumen 104 of vessel 102. The distal end of procedural device 108 is shown riding along a guidewire 110. Procedural device 108 passes through a procedural sheath 106, which maintains access to lumen 104 through a tissue track 101 in tissue 100 and arteriotomy 132 in the wall of vessel 102.

[0057]As the intra-luminal procedure, such as balloon angioplasty, is completed, procedural device IDS is removed from vessel 102 and ti...

Abstract

A method for closing an arteriotomy includes providing a guiding system and a closure system. The guiding system is mounted over a dilator, and advanced along a guidewire through the arteriotomy and into the blood vessel lumen. The guiding system includes two stabilization wire guides. A retention foot is disposed at a distal portion of each stabilization wire guide, the foot being deployable into contact against an inner surface of the vessel wall. The guidewire and dilator are withdrawn from the patient, leaving the stabilization wire guides in place. The closure system carries a stapler and is advanced along the stabilization wire guides to an extraluminal position. The stapler is then activated to close the arteriotomy. The retention feet are undeployed and the guiding and closure systems are withdrawn from the body, leaving a staple to hold the arteriotomy closed.

Description

FIELD OF THE INVENTION [0001]The present disclosure relates to system and method for closing an opening in a vessel wall after a medical procedure, and in particular, to a system and method for closing a puncture arteriotomy after an intracranial procedure such as catheterization.BACKGROUND OF THE INVENTION [0002]Catheters / catheterization procedures for diagnosis or treatment of cardiovascular and / or peripheral vascular diseases are well known, and typically involve the Seidinger technique to make insertions through layers of tissue and through a wall of the femoral artery. After a diagnostic or interventional catheterization, the arteriotomy puncture formed by the catheter or introducer sheath must be closed. The puncture opening in the artery typically ranges from 5 French (0.0655 inch, 1.67 mm) such as for a diagnostic angiography procedure to as large as 30 French (0.393 inch, 10.00 mm) for an interventional procedure such as implanting an inferior vena cava (IVC) filter. Tradit...
