Atraumatic blood access device

Abstract

Abstract A device for a traumatic access to a blood vessel of a living organism through the cutaneous surface thereof. The device includes in combination an implantable device comprising a tubular segment for access to the blood vessel; a valving element for the tubular segment; a mechanism for controlling the blood flow through the valving element; a cover for sealing the proximal end of the tubular segment in the absence of the blood control mechanism; and a porous coating adapted to be colonized by tissue ingrowth and at least partially surrounding the implantable device. The porous coating is formed from a carbon-carbon composite material comprising a reinforcement formed from a carbon fiber porous substrate embedded in a carbonaceous matrix design to densify only partially the fiber substrate while connecting the carbon fibers together.
