Abstract:
1. A catheter assembly for restoring blood flow to a traumatized blood vessel, comprising: a catheter body, in a tubular shape, comprising: a first and a second tip, each configured to permit insertion into a blood vessel without damaging an inner wall of a blood vessel lumen; a first and a second set of a plurality of fenestrations, disposed proximate to each tip extending a length of the catheter body away from each tip towards a center portion of the tubular catheter body; a first and a second inflatable device, placed circumferentially and longitudinally about the catheter body, configured such that when uninflated each is capable of sliding over a section of the catheter body, and when inflated an inner annulus of each presses against an outer perimeter of the catheter body; a first and a second pleat, spaced apart by a midsection, located in the center portion of the catheter body between the first and the second inflatable device; at least one obstructing stop, located on the outer perimeter of the catheter body in a section longitudinally adjacent to each of the first and the second set of the plurality of fenestrations towards the center portion, to obstruct the first or the second inflatable device from sliding over the first or second set of a plurality of fenestrations proximate to the first or the second tip of the catheter body, and a first and a second flexible tube connected to the first and the second inflatable device, respectively, and adapted to allow fluid communication from a pumping device with the first and the second inflatable device, wherein the first and the second pleats are capable of expanding on one side relative to another side to enable curving and bending of the catheter body in a vicinity of the first and the second pleats, and wherein the midsection is configured to receive an external clamp.
