Abstract
A method for advancing a stent through a constricted lumen of a patient, in which a medical device having an access tube is urged into the lumen via a slip wire. The access tube defines a tubular body having a slip wire connected thereto. The access tube is advanced into the lumen by feeding the slip wire to a point of partial blockage. The access tube is configured to radially compress or comply upon encountering a narrowed area of the lumen. A stent may then also be advanced to the point of blockage, where it enters the compliant access tube. The stent is then urged through the constricted portion of the lumen by traversing the compliant access tube. Preferably, the access tube has a slit running along its length, and is fabricated from a hydrophilic material.
