  • Patent number: 6569180
    Abstract: An intravascular balloon catheter comprises a tubular catheter body having a balloon structure removably mounted over the catheter body. The catheter body has a guidewire lumen , and the catheter body may be left in place within a patient's vasculature while the balloon structure is withdrawn and optionally a second balloon structure introduced over the catheter body. The catheter and methods of the present invention are particularly suitable for performing angioplasty and subsequent procedures, such as stent placement, which are best performed using successive interventional balloon structures.

  • Publication number: 20030083646
    Abstract: The present invention provides improved stents and other prostheses for delivering substances to vascular and other luminal and intracorporeal enviroments. In particular, the present invention provides luminal prostheses which allow for a programmed and controlled substance delivery protocols for a variety of purposes. The prostheses comprise a scaffold which is implantable within a body lumen and a substance reservoir present over at least a portion of the scaffold. Usually, a rate-controlling element will be formed over the substance-containing reservoir to provide for a number of different substance release characteristics.

  • Publication number: 20030050692
    Abstract: Devices and methods for reducing, inhibiting, or treating restenosis and hyperplasia after intravascular intervention are provided. In particular, the present invention provides luminal prostheses which allow for controlled release of at least one therapeutic capable agent with increased efficacy to selected locations within a patient's vasculature to reduce restenosis. An intraluminal prosthesis may comprise an expandable structure and a source adjacent the expandable structure for releasing the therapeutic capable agent into a body lumen to reduce smooth muscle cell proliferation.

  • Publication number: 20030017190
    Abstract: The present invention provides improved devices and methods for minimizing and/or inhibiting restenosis and hyperplasia after intravascular intervention. In particular, the present invention provides luminal prostheses which allow for programmed and controlled mycophenolic acid delivery with increased efficacy to selected locations within a patient's vasculature to inhibit restenosis. An intraluminal delivery prosthesis may comprise an expansible structure and means on or within the structure for releasing mycophenolic acid at a rate selected to inhibit smooth muscle cell proliferation.
