  • Patent number: 11648136
    Abstract: This invention provides for a radially expandable stent having superior strength and reduced foreshortening properties. The stents have a mixed configuration of straight and arcuate connector segments that serve to join annular segments that make up the body of the stent. Surprisingly the described mixed configuration provides superior resistance to flip deformation while maintaining desired flexibility.

  • Publication number: 20180289550
    Abstract: Methods, materials, articles, assemblies, systems, devices, kits and computer hardware/software for improving medical procedures, including, but not limited to, hemodialysis. Particular beneficial designs and uses of disinfecting patches, scab removal patches, hemostatic patches, healing patches and artificial scabs are included. For example, scab removal patches that avoid tenting, hemostatic patches with needle stabilizing elements, hemostatic patches applying pressure at a skin puncture site and a vessel puncture site, artificial scabs that release antimicrobial agents, etc.

  • Publication number: 20060229706
    Abstract: An intravascular stent and method for inhibiting restenosis, following vascular injury, is disclosed. The stent has an expandable, linked-filament body and a drug-release coating formed on the stent-body filaments, for contacting the vessel injury site when the stent is placed in-situ in an expanded condition. The coating releases, for a period of at least 4 weeks, a restenosis-inhibiting amount of the macrocyclic triene immunosuppressive compound everolimus. The stent, when used to treat a vascular injury, gives good protection against clinical restenosis, even when the extent of vascular injury involves vessel overstretching by more than 30% diameter. Also disclosed is a stent having a drug-release coating composed of (i) 10 and 80 weight percent of a polymer substrate and (ii) 20-90 weight percent of an anti-restenosis compound.

  • Publication number: 20060069427
    Abstract: A radially expandable, endovascular stent designed for placement at a site of vascular injury, for inhibiting restenosis at the site, a method of using, and a method of making the stent. The stent includes a radially expandable body formed of one or more metallic filaments and a liquid-infusible mechanical anchoring layer attached to or formed in outer surface of the filaments. A drug coating in the stent is composed of a substantially polymer-free composition of an anti-restenosis drug, and has a substratum infused in the anchoring layer and a substantially continuous surface stratum of drug that is brought into direct contact with the vessel walls at the vascular site. Thus, the rate of release of the anti-restenosis drug from the surface stratum into said vascular site is determined solely by the composition of said drug coating.

The stent has an expandable, linked-filament body and a drug-release coating formed on the stent-body filaments, for contacting the vessel injury site when the stent is placed in-situ in an expanded condition. The coating releases, for a period of at least 4 weeks, a restenosis-inhibiting amount of a monocyclic triene immunosuppressive compound having an alkyl group substituent at carbon position 40 in the compound. The stent, when used to treat a vascular injury, gives good protection against clinical restenosis, even when the extent of vascular injury involves vessel overstretching by more than 30% diameter. Also disclosed is a stent having a drug-release coating composed of (i) 10 and 60 weight percent poly-d/-lactide polymer substrate and (ii) 40-90 weight percent of an anti-restenosis compound, and a polymer undercoat having a thickness of between 1-5 microns.
