  • Publication number: 20240108449
    Abstract: Apparatus and methods for retrieving a foreign body from a vasculature are provided. The devices can be Funnel-trap type retrieval devices. The devices can include a compressible support member extending from the distal end of an elongate shaft, the compressible support member having an expanded configuration, a compressed configuration, a plurality of independent elongate support elements that have a memory for the funnel-shaped expanded configuration, and a cover material that covers the compressible support member and forms a pocket configured for capturing the foreign body in the interior of the compressible support member.

  • Publication number: 20060229712
    Abstract: A method of mounting a drug delivery stent on a balloon of a balloon catheter. The method securely mounts the drug delivery stent on the balloon without damaging the drug delivery layer of the stent. In one embodiment, the method generally comprises positioning a drug delivery stent on a balloon of a balloon catheter, and positioning the balloon with the drug delivery stent thereon within a polished bore of a mold formed at least in part of a metallic material. The balloon is pressurized and heated within the mold as the mold radially restrains the stent from expanding, to mount the stent on the balloon without damaging the drug delivery layer of the stent.

  • Patent number: 5605696
    Abstract: The drug loaded polymeric material containing a therapeutic drug can be applied to a structure of an intravascular stent. A therapeutically effective amount of a therapeutic drug is incorporated into such a layer of polymeric material, without significantly increasing the thickness of the stent, to avoid interfering with the function of the stent. The drug loaded polymer coating of the stent can formed to include pores, can be multi-layered to permit the combination of a plurality of different drug containing materials in a single stent, and can include a rate controlling membrane to allow for controlled retention and delivery of selected drugs within the affected blood vessel upon implantation. The layer of polymeric material is manufactured by combining the selected polymeric material with a relatively high loading of the therapeutic drug in a thermal process, such as coextrusion of the therapeutic drug with the polymeric material.
