IMPLANTABLE AND REMOVABLE CUSTOMIZABLE BODY CONDUIT

摘要

An apparatus and method are provided to treat a stenosis. A delivery device is provided that has an elongate tubular member coupled therewith. The elongate tubular member has an outside surface that is configured to prevent adherence of in vivo matter. The tubular member has a proximal end and a distal end and is reinforced along its length to maintain open lumen under a transverse load. The tubular member is placed in the vasculature such that the distal end of the elongate tubular member is disposed distal of a stenosis. The proximal end of the elongate tubular member is disposed inside the vessel, preferably at a location proximal of the stenosis. Thereafter, after a therapeutic period, the elongate tubular member is removed intact.

主权项

1. A catheter for bypassing a stenosis, the catheter comprising:
an elongate body comprising a proximal portion, a distal portion, and a lumen extending therebetween along a longitudinal axis, wherein the proximal portion is configured to be positioned proximal of the stenosis and the distal portion is configured to be positioned distal of the stenosis; an inner surface of the elongate body defining the lumen and an outer surface of the elongate body surrounding the inner surface; and a braided structure embedded within the elongate body about the lumen; wherein the proximal portion of the elongate body and the braided structure are configured to respond to an axial force by expanding such that the lumen is enlarged for advancement over an engagement feature.
