Problems solved by technology

Additionally, the three-layer conduit structure of the '294 patent has limitations in wall thickness because of the need to be able to handle and assemble the three layers of the conduit during production.
Additionally, the catheter structure makes it difficult to have a large lumen diameter while maintaining flexibility and / or kink resistance against very sharp bends in the vessel

Embodiment Construction

[0019] FIG. 1 shows a schematic diagram of an exemplary catheter 105. The catheter 105 is an elongated body, which has an outer dimension that is sized and shaped to be inserted into a blood vessel. In one embodiment, the size and shape of the catheter 105 are configured to be inserted into the carotid artery access system described in the U.S. Patent Application Serial No. 12 / 834,869 entitled "System and Method for Treating Carotid Artery", for example. Into the sheath, the said US patent application is incorporated herein in its entirety by reference. US Patent Application Serial No. 14 / 537,316, titled "Method and Device for Transcarotid Access" and filed on November 10, 2014, is also incorporated herein by reference in its entirety. The proximal region of the catheter 105 may have one or more mechanical or electromechanical control mechanisms for controlling different components on or near the distal end of the catheter 105. For example, the control mechanism can be used t...

Abstract

An interventional catheter for treating an artery includes an elongated body sized and shaped to be transcervically introduced into a common carotid artery at an access location in the neck. The elongated body has an overall length such that the distal most section can be positioned in an intracranial artery and at least a portion of the proximal most section is positioned in the common carotid artery during use.
