  • Patent number: 10383750
    Abstract: A stent (scaffold) or other luminal prosthesis comprising circumferential structural elements which provides high strength after deployment and allows for scaffold to uncage, and/or allow for scaffold or luminal expansion thereafter. The circumferential scaffold may be formed from degradable material, or may be formed from non-degradable material and will be modified to expand and/or uncage after deployment.

  • Publication number: 20190201225
    Abstract: A stent or other luminal prosthesis is delivered by a catheter having a contoured balloon. The contoured balloon may include a central dome region flanked by at least one adjacent flat or cylindrical region. The central domed region and adjacent flat or cylindrical regions are joined at shallow angles to provide for an incrementally larger expansion of the center region of the stent while minimizing shear forces during expansion.

  • Patent number: 7238168
    Abstract: An intravascular balloon catheter includes 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lumen, and the catheter body may be left in place within a patient's vasculature while the balloon structure is withdrawn and optionally a second balloon structure introduced over the catheter body.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: 20070142898
    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 mizoribine 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 mizoribine into the body lumen to inhibit smooth muscle cell proliferation.
