Embodiment Construction

[0057] Specific embodiments of the present invention will now be described with reference to the drawings, wherein like reference numerals indicate identical or functionally similar elements. The terms "distal" and "proximal" are used in the description below in conjunction with position or orientation relative to the treating clinician. "Distal" and "distal" are positions away from or in a direction away from the clinician, and "proximal" and "proximally" are positions near or toward the clinician direction.

[0058] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Although the present invention is described in the context of the treatment of an arteriotomy (which is used herein to refer to an opening, incision, or incision of an artery), the present invention may also be used in any other blood vessel or bodily access that is deemed useful. . For example, the device ma...

Abstract

A suturing device includes a handle, an elongated body, at least one suture snag, at least one pair of needles, and at least one suture pair. The suture snag is moveable between a deployed position in which two distal arm portions thereof radially extend away from the elongated body and a retracted position in which the two distal arm portions are disposed within the elongated body. The suture pair is slidingly disposed through the needle pair. The suturing device deploys the suture snag within a vessel adjacent to an arteriotomy, extends the needle pair through a vessel wall around the arteriotomy and through the deployed suture snag, extends the suture pair beyond the distal ends of the needle pair, and then utilizes the suture snag to capture the extended suture pair by retracting the suture snag to pull first or distal ends of the sutures back into the suturing device.

Description

technical field [0001] The present invention relates to medical suturing devices, and more particularly to suturing devices for closing openings in walls of arteries or other biological tissue that are not directly accessible to the user. Background technique [0002] Various cardiovascular procedures such as angioplasty, stenting and atherectomy require gaining access to the vasculature. 1 and 2, access to the vasculature of patient 100 is typically through the femoral artery and is percutaneous, involving a needle (not shown) and in some cases a dilator (not shown) in the region of the groin Insertion to form a path 104 through the subcutaneous tissue 106 and puncture the vessel wall V of the femoral artery W and create an arterial incision in the vessel wall V A . Then, the guidewire GW is advanced through the needle and into the femoral artery. The needle and dilator (if present) are then removed. The catheter or other interventional device 102 is then advanced over...
