  • Composite ePTFE/textile prosthesis
    Patent number: 7828833
    Abstract: A composite intraluminal prosthesis which is preferably used as a vascular prosthesis includes a layer of ePTFE and a layer of textile material which are secured together by an elastomeric bonding agent. The ePTFE layer includes a porous microstructure defined by nodes interconnected by fibrils. The adhesive bonding agent is preferably applied in solution so that the bonding agent enters the pores of the microstructure of the ePTFE. This helps secure the textile layer to the ePTFE layer.

  • BLOOD ACESS APPARATUS AND METHOD
    Publication number: 20080306580
    Abstract: A blood access for dialysis includes a radially distensible support structure having an open lattice structure defining a support wall having interstitial open areas and defining exterior and luminal wall surfaces; a first porous polymeric portion having a plurality of pores, the first porous polymeric portion being securably disposed over at least a portion of the exterior wall portion of the support structure; a second porous polymeric portion having a plurality of pores, the second porous polymeric portion being securably disposed over at least a portion of the luminal portion of the support structure; and a biodegradable and/or bioabsorbable material disposed within the pores of the first polymeric portion and/or pores of the second polymeric portion.
