Abstract:
A forwardly directed fluid jet crossing catheter having a distally directed cylindrical flow fluid jet stream to cross a chronic total occlusion is set forth. The distal end of the device includes a formable catheter tip region having flexible internal components. Low and high pressure cavities are formed substantially by joined proximal and distal catheter tubes having an adhesive plug seal in common therebetween which partially defines one end of each of the low pressure and high pressure cavities. A guidewire tube and a high pressure tube are aligned along and within the low pressure and high pressure cavities and through the adhesive plug seal. The high pressure tube openly terminates in the high pressure cavity, whereby pressurized fluid transfers from the high pressure cavity in the guidewire tube entry hole to subsequently pass along the guidewire lumen and co-located guidewire to exit as a cylindrical fluid jet stream.
