Abstract of corresponding document: US6482218
The present invention pertains to a wire-shaped ultrasonic catheter for ultrasonic angioplasty. The ultrasonic catheter head is provided with a diamond coating. The catheter has a cylindrical sonotrode and a thin ultrasound catheter which together form a resonant system. The catheter is made from a thin stainless steel ultrasound waveguide. The catheter is coupled to a mechanical connection system at one end and at the other end to a hardened, bulb-shaped stainless steel catheter tip having a cylindrical, spherical or rounded conical shape with a diamond powder coating.
