Patent ID: 8162878

Claim:
An exhaust-pressure-operated balloon catheter thrombectomy system for use within a vessel comprising: a. a manifold including: (1) a central tubular body; (2) a high pressure branch including an integral threaded connector port extending angularly from the central tubular body; (3) an exhaust branch including an integral threaded connector port extending angularly from the high pressure branch; and, (4) a cavity body, having a hemostatic nut assembly, extending proximally from the central tubular body; b. a catheter tube formed from a first material, including an exhaust lumen, extending distally from the manifold through a strain relief and toward a distally located tapered tip; c. a plurality of outflow and inflow orifices on the catheter tube and in communication with the exhaust lumen in close proximity to the tapered tip; d. a high pressure tube connectively extending from the high pressure branch, through the manifold and through the catheter tube to a fluid jet emanator located distal to the plurality of outflow and inflow orifices, and a fluid distally carried under high pressure from the manifold to the fluid jet emanator; e. an inflatable thin walled section balloon formed from the first material of the catheter tube and aligned between two sections of full wall catheter tube proximal to the plurality of outflow and inflow orifices, where the outflow and inflow orifices are between the fluid jet emanator and the thin walled section balloon, and the outflow and inflow orifices are in communication with the thin walled section balloon and the emanator through the exhaust lumen; and f. the exhaust lumen of the catheter tube communicating with the thin walled section balloon, the exhaust lumen and thin walled section balloon of the catheter tube being sustainably pressurized by a proximal exhaust flow of the fluid from the fluid jet emanator and an entrained fluid from the inflow and outflow orifices, the proximal exhaust flow crossing the inflow and outflow orifices between the emanator and the thin walled section balloon and combining with the entrained fluid, and the proximal exhaust flow including the fluid from the fluid jet emanator and the entrained fluid inflating the thin walled section balloon into an expanded configuration.
