Publication number: 20180345624Abstract: A composite intraluminal prosthesis which is preferably used as a vascular prothesis 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.Type: ApplicationFiled: July 30, 2018Publication date: December 6, 2018Applicant: MAQUET CARDIOVASCULAR LLCInventors: Krzysztof Sowinski, Ronald Rakos, Jerry Dong, Dennis Kujawski, Patrick A.

Patent number: 7806848Abstract: A graft, for example, an arterio-venous shunt graft, is provided, which in a first aspect of the subject invention, is formed with longitudinal ribs. With fibrotic tissue ingrowth between the ribs, a composite rib/tissue layer is formed about the graft. The ribs provide counteracting lateral force against the embedded tissue to seal punctures formed therethrough during hemodialysis procedures. To provide additional surface area for puncturing, the graft may be formed with a truncated cross-section. With a second aspect of the invention, the graft is mounted onto a strip to prevent kinking, twisting or bending during an implantation procedure.Type: GrantFiled: August 22, 2006Date of Patent: October 5, 2010Assignee: Boston Scientific Scimed, Inc.Inventors: Jamie S.
