International Classification:

A61F002/06

US Classification:

623/001440

Abstract:

A vascular graft comprising a traditional graft material and an electrospun fibrous layer. The solvent used to reduce the material for the electrospun layer is also capable of reducing the graft material to a liquid solution. The electrospun layer is chemically bonded to the graft material, without adhesives, by either spraying the graft with the solvent prior to electrospinning or by assuring that a sufficient amount of residual solvent reaches the graft while electrospinning.

Manuel Marques - Newark NJ

Assignee:

Datascope Investment Corp. - Montvale NJ

International Classification:

A61N 1362

US Classification:

600 18

Abstract:

An improved intra-aortic balloon catheter with a balloon membrane, a tip, and a co-lumen extruded tube having an outer lumen and an inner lumen between the inner and outer surfaces of the co-lumen extruded tube. The portion of the co-lumen extruded tube that defines the inner lumen and which is disposed within the balloon membrane is made from polyimide, a lubricous material, to facilitate guide wire tracking. The polyimide inner tube portion demonstrates good kink resistance and flexural stiffness. In a first alternative embodiment of the invention the co-lumen tube comprises an outer tube with an inner tube embedded in the wall of said outer tube. In a second alternative embodiment of the invention a longitudinal signal pathway is provided.
