Patent ID: 8012117

Claim:
A thrombectomy catheter device for use in treating neurological anatomy comprising a manifold having a main body with a longitudinal axis, said main body having an upstream end and a downstream end, a liquid input port connected to said upstream end of said main body, an exhaust branch connected to said main body near said upstream end of said main body, and an elongated flexible catheter connected to said downstream end of said main body, said flexible catheter having a distal end and an internal high pressure tube for receiving and transmitting therethrough a liquid from said input port, said internal high pressure tube having a fluid jet emanator at a downstream end thereof said fluid jet emanator has a downstream termination in the form of a semi-loop in an arc of about 160 degrees and said flexible catheter having spaced output and input orifices upstream from said fluid jet emanator wherein said internal high pressure tube comprises successive flexible sections made from stainless steel, nitinol, and stainless steel whereby a nitinol to stainless steel bond is formed near the downstream end, said bond being formed via laser swaging with gold plating and said distal end of said flexible catheter has a diameter of about 3 French.
