Patent ID: 8795288

Claim:
A device for providing access to a treatment site within the body of a patient, comprising: a tubular member having a proximal portion and a distal portion, said distal portion extending to a distal end, said tubular member having a first, generally elongated configuration for introduction into a first vessel in the body of the patient, and being deployable therein to a second configuration wherein said proximal portion and said distal end remain at least substantially in the generally elongated configuration, and a segment of said distal portion proximal of said distal end is axially displaced from said generally elongated configuration of said proximal portion and said distal end, said tubular member comprising a side port disposed on said axially displaced segment, said tubular member further comprising a first lumen communicating with said side port, said axially displaced segment and said side port alignable in said first vessel for passage therethrough of an interventional device for delivery to said treatment site in a second vessel, said second vessel branched from said first vessel; and an actuating wire extending through a second lumen of said tubular member, said first and second lumens being separated from each other, said second lumen and said actuating wire extending along said tubular member to a first port adjacent a proximal side of said axially displaced segment, said actuating wire exiting said second lumen and said tubular member through said first port and extending external of said tubular member and parallel therewith, said actuating wire reentering said second lumen and said tubular member through a second port adjacent a distal side of said axially displaced segment, said actuating wire extending through said second lumen to said distal end of said tubular body, said second lumen being closed off adjacent said distal end of said tubular body, and a distal end of said actuating wire being attached to said tubular body adjacent said distal end of said tubular body; wherein said segment of said tubular body is axially displaced in response to tension exerted on said actuating wire.
