SURGICAL APPARATUS FOR ANEURYSMS

摘要

A surgical apparatus for aneurysms includes a stent(1), a delivery guide wire(2), an introducer sheath(3), and a microcatheter(4). The stent(1) is a self-expanding stent; the delivery guide wire(2) outside which the stent(1) is restrained is provided in a lumen of the introducer sheath(3); the introducer sheath(3) is connected with the microcatheter(4), with lumens communicating, to form a passageway through which the delivery guide wire(2) and the stent(1) are delivered into a human body. The surgical apparatus for aneurysms is able to deliver and release the stent(1) which has high density and is super soft to a vascular lesion. A lattice structure of the stent(1) is of high coverage at the vascular lesion such that the stent(1) released into the vessel produces the same effects as healing of parent vessel, and thus improves the treatment of vascular aneurysms.
