Patent ID: 7959644

Claim:
A hemostatic guiding catheter device for establishing a tubular passageway in a peripheral artery or vein from entry at a percutaneous site through an arteriotomy site to a site distal to said entry and for preventing blood from flowing out of said arteriotomy site, said hemostatic guiding catheter having an outside circumference and an inside circumference with a wall therebetween, a proximal end, a distal end, and a lumen therebetween, said lumen having a proximal opening and a distal opening; said hemostatic guiding catheter being smaller in said outside circumference than the inside circumference of said peripheral artery or vein; and being made of a hard, semi-flexible material such as wound stainless steel wire, flexible metal or polymers; said hemostatic guiding catheter having a permanently bent shape for pointing said distal opening away from said longitudinal axis and toward said arteriotomy site and deflecting elongated instruments or other objects guided inside said lumen; said distal opening having a saddle-shaped edge congruent with a shape of the arteriotomy site on said peripheral artery or vein; one or more annular balloons attached to said distal end of said hemostatic guiding catheter, the one or more annular balloons having a pre-selected shape when inflated that constitute one or more barriers to the flow of blood and made of such material as polyurethane or thermoplastic elastomers; one of said one or more annular balloons, always present and nominally called next most distal balloon, biased to inflate with an extreme overhang away from a point of attachment around said edge of the distal opening, like a foreskin over a penis, thus forming a tube shape ending in a saddle-shaped edge at a junction with said artery wall to constitute a first second barrier to the flow of blood into said arteriotomy, and expanding largely in the direction opposite to said arteriotomy site to push against said artery wall opposite said arteriotomy site and also in all directions to fill a space between said outside circumference of said hemostatic guiding catheter and said inside circumference of said peripheral artery to constitute a second barrier to the flow of blood, wherein at least a portion of said hemostatic guiding catheter located inside said next most distal balloon slides forward like a penis through said arteriotomy; and one or more flexible tubes for carrying fluid from outside said percutaneous opening to said one or more annular balloons, said flexible tubes being made of a polymeric material, wherein said hemostatic guiding catheter provides a tubular passageway for guiding elongated instruments and other objects through and out of said peripheral artery to form the arteriotomy and a bypass graft around an occlusion in said peripheral artery.
