Embodiment Construction

[0040] figure 1 is a perspective view of a vessel access and closure device 100 according to the present invention, shown in a partially deployed position for placement of a continuous suture into the wall of a vessel V. FIG. figure 2 yes figure 1 An exploded view of the vessel access and closure device 100 of FIG. image 3 is showing figure 1 A cross-sectional view of the internal structure of the blood vessel access and closure device 100.

[0041] Vascular access and closure device 100 has an elongated shaft portion 104 with a proximal end 106 and a distal end 108 . Proximal handle 102 is connected to elongated shaft portion 104 at proximal end 106 . The proximal handle 102 has a fixed portion 110 and a rotating portion 112 proximate to the fixed portion 110 . Preferably, the turning portion 112 of the proximal handle 102 will have a contour 116 and / or texture configured to facilitate the operator's grip to apply torque to turn the turning portion 112 . Additional...

Abstract

A vessel access and closure device places a running suture in the wall of a blood vessel using a rotating helical suture needle that carries the suture along a helical path passing through the vessel wall, then reverses rotation to release a suture anchor attached to the distal end of the suture. A loose helical coil of suture is left behind as the helical suture needle withdraws. The device is withdrawn and replaced with a vessel dilator and an introducer sheath that opens up a larger access opening into the blood vessel and creates a pathway that passes though the helical coil of suture for introducing an interventional device into the blood vessel. After the interventional procedure is completed, the interventional device and the introducer sheath are withdrawn and the running suture is tightened and secured with a suture lock to close the access opening into the vessel.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 210,018, filed March 14, 2009, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to devices and methods for obtaining percutaneous access to the lumen of a blood vessel and for subsequently closing the access site into the blood vessel. The invention is particularly advantageous for facilitating percutaneous access and closure of blood vessels with larger diameter interventional devices. Background technique [0004] Minimally invasive, catheter-based interventions have revolutionized the treatment of vascular disease in many ways. In many interventional procedures, the interventional device is introduced into the body via the patient's femoral artery or vein (percutaneously). The average diameter of the femoral artery in an adult patient is about 12 mm in outer diameter...
