Systems And Methods For Treating A Carotid Artery

摘要

Systems and methods are adapted for treating the carotid artery. The systems include interventional catheters and blood vessel access devices that are adapted for transcervical insertion into the carotid artery. Embodiments of the systems and methods can be used in combination with embolic protection systems including blood flow reversal mechanisms, arterial filters, and arterial occlusion devices.

主权项

1. A method for treating a carotid artery, comprising:
inserting an arterial access device into a common carotid artery, wherein the access device includes a distal sheath adapted to be transcervically introduced into a carotid artery through a penetration in a wall of the carotid artery; inserting an interventional catheter adapted for transcervical insertion into the carotid artery via the arterial access device, wherein the interventional catheter is adapted to deploy a stent and wherein the interventional catheter includes a first hemostasis valve positioned on a proximal end of the arterial access device, and wherein the interventional catheter is formed of:
(a) an elongated inner member having a distal region on which the stent may be mounted, the elongated inner member further having a protrusion on a proximal portion of the elongated inner member;(b) an elongated stent containment sheath coaxially positioned over the inner member, the stent containment sheath formed by an annular side wall, wherein an opening is formed through a proximal portion of the annular side wall of the stent containment sheath, and wherein the protrusion of the inner member extends outward through the opening such that the protrusion of the inner member may be accessed by a user at a location outside the stent containment sheath; treating an artery using the interventional catheter.
