    摘要: A resizable inflatable balloon, primarily for use with balloon catheters. The resizable inflatable balloon comprises a first portion and an adjacent second portion. The first portion is inflatable to a working diameter at a first pressure while the second portion does not substantially expand at the first pressure. The second portion does expand to the working diameter at a second pressure greater than the first pressure, so that subsequent inflation at the first pressure inflates the first portion and the second portion to the working diameter. The methods of resizing the inflatable members include placing the inflatable balloon in a mold and supplying inflation fluid to expand the second member to the working diameter. In practice, a catheter having the resizable inflatable balloon is guided through a patient's vasculature until the inflatable balloon is positioned in a desired region. Inflation fluid is supplied at the first pressure to inflate the first portion to the working diameter. The catheter is withdraw and the inflatable balloon is resized as described above. The catheter is reintroduced to the patient's vasculature and inflation fluid is then supplied at the first pressure to inflate both the first and second portions.

    摘要: An elongated intracorporeal device, more specifically, a balloon catheter having an elongate shaft with a distal section. The distal section of the shaft has a distal inner tubular member with an inflatable balloon disposed about the distal inner tubular member. A radiopaque marker formed at least in part of a polymer is disposed on the distal inner tubular member. The flexible radiopaque marker can be formed either by doping a desired portion of the distal inner tubular member with an appropriate radiopaque material, or preforming the radiopaque marker from a polymer doped with a radiopaque material and subsequently securing the radiopaque marker to the distal inner tubular member.
