Abstract:
1. A thrombectomy catheter comprising: a manifold having a central elongated tubular body with a proximal end and a distal end; an elongated flexible catheter tube having a proximal end and a distal portion, said proximal end of said catheter tube extending into and distally from said distal end of said central elongated tubular body of said manifold; said elongated flexible catheter tube continuous with an elongated distal section, said elongated distal section of said catheter tube having a proximal portion and a distal end; a fluid jet emanator having a plurality of spaced jet orifices, said fluid jet emanator secured between the proximal portion of the elongated distal section and the distal portion of the elongated flexible catheter tube; said elongated distal section having a first inflow orifice near said proximal portion thereof and distal relative to the secured fluid jet emanator; said elongated flexible catheter tube having a second inflow orifice near said distal portion thereof and proximal relative to the secured fluid jet emanator; a self-inflating balloon interposed between said first inflow orifice and said distal end of said elongated distal section; and an elongated flexible high pressure tube having a proximal end in fluid communication with a fluid source and a distal end in fluid communication with the fluid jet emanator, wherein the first inflow orifice is interposed between and in communication with the fluid jet emanator and the self-inflating balloon, and the self-inflating balloon is pressurized into an expanded configuration by a distal flow of fluid from the fluid jet emanator.
