  • Patent number: 11911523
    Abstract: An embodiment includes a wound dressing comprising: a shape memory polymer (SMP) foam, including open cells, having first and second states; and a hydrogel (HG) included within the cells; wherein (a) in a first position a composite, including the SMP foam and the HG, is configured to be located proximate a hemorrhagic tissue with the SMP foam in the first state; (b) in a second position the composite is configured to be expanded to the second state against the hemorrhagic tissue when the SMP foam is plasticized at 37° C. depressing a glass transition temperature (Tg) of the SMP foam to below 25° C. Other embodiments are described herein.

  • Publication number: 20150216688
    Abstract: The present invention provides a braided coil catheter to delivery of a vascular implant through a catheter including a braided coil adapted to at least partially retain a vascular implant comprising a braided coil distal tip, a braided coil proximal end connected by a braided coil body having a lumen with a lumen diameter; a friction plug comprising a proximal friction plug end, a distal friction plug end connected by a friction plug body with a friction plug diameter greater than the lumen diameter to frictionally fit into the lumen of the braided coil distal tip; a vascular implant having an implant mating end, an implant non-mating end connected by an implant body wherein the implant mating end is connected to the distal friction plug end; and a pusher catheter inserted into the lumen and to contact the proximal friction plug end and force the friction plug from the lumen.
