Systems and methods for treating a carotid artery
First Claim
Patent Images
1. A system for treating a carotid artery, comprising:
- an arterial access device wherein the access device includes a distal sheath adapted to be transcervically introduced into a carotid artery, the arterial access device further including a proximal extension having a distal end, a proximal end, and a lumen therebetween, wherein the distal end of the proximal extension is connected to a proximal end of the distal sheath at a junction so that the lumens of each are contiguous;
a proximal extension connected to the distal sheath and having a distal end, a proximal end, and a lumen therebetween, wherein the distal end of the proximal extension is connected to a proximal end of the distal sheath at a junction so that the lumens of each are contiguous;
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;
wherein the interventional catheter is formed of;
an elongated inner member having a distal region on which a stent may be mounted, the elongated inner member further having a protrusion on a proximal portion of the elongated member;
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.

Abstract
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.
