  • Publication number: 20050137617
    Abstract: An elastically distensible folding member is disclosed. The folding member can be formed with a wall that is substantially shaped as a tube when the folding member is in a relaxed (i.e. unstressed) state. The tubular shaped folding member defines a tube axis and can have an axially aligned slit that extends through the wall. The folding member can be used to cover an incising element that is attached to the balloon and positioned in the lumen of the tubular folding member. During balloon inflation, the folding member can be deformed to expose the tip of the incising element to allow for a tissue incision.

  • Publication number: 20050137616
    Abstract: A sheath is provided to protect a blade when the blade is mounted on a balloon catheter. In particular, this protection is provided while the balloon is deflated for maneuver of the catheter through the vasculature of a patient. The sheath itself is a tubular shaped member that is bifurcated into substantially symmetric halves. Further, the sheath forms a channel for protecting the blade when its halves are juxtaposed. An adhesive bonds both halves of the sheath to the surface of the balloon. When the balloon is deflated, its halves are juxtaposed to cover the blade in the protective channel. On the other hand, when the balloon is inflated, the expanded surface of the balloon pulls the opposed sheath halves that are bonded to it from each other, to thereby expose the blade.

  • Patent number: 5336234
    Abstract: An apparatus and method of operation are disclosed for using an expandable balloon catheter to perform a combination angioplasty and atherectomy procedure on a stenotic blood vessel. The expandable balloon has a plurality of atherotomes attached to its outer surface, and longitudinal, transverse, or rotational oscillatory motion is imparted to the atherotomes to assist in incising the stenotic tissue, prior to or during dilatation of the stenotic segment of the blood vessel.

  • Patent number: 5209799
    Abstract: A method of manufacturing a folding balloon catheter for use as an angioplasty device, wherein the balloon catheter has atherotomes attached to the exterior of the balloon, includes inflating a balloon to its expanded state. A plurality of patches of a curable elastomer adhesive are then applied at selected locations on the outside surface of the inflated balloon, and an atherotome is attached to the balloon at each of the patches. The inflated balloon, with attached atherotomes, is then partially cured to more firmly attach the atherotomes to the balloon. The balloon is then deflated to a contracted configuration in a manner which forms a plurality of flaps in the balloon between the atherotomes. The deflated balloon is then cured to completion to establish a permanent set in the flaps which enable the balloon catheter to be repeatedly inflated and deflated during operation between predictable expanded and contracted configurations.
