Lithotripsy eye treatment

摘要

A lithotripsy probe is used to break up cataracts, sinus blockages and other body masses, where the broken materials may be removed by suction. The lithotripsy probe may have a spark generator, a fluid motion generator, or other component for breaking up the body mass.

主权项

1. A method of treating a cataract in an eye, the method comprising:
advancing a distal end of a lithotripsy probe into the eye in proximity with the cataract; activating the lithotripsy probe to break the cataract into multiple pieces by causing fluid to move forward from a nozzle at the distal end of the lithotripsy probe, wherein causing fluid to move forward from the nozzle comprises generating a shock wave in the nozzle near the distal end of the lithotripsy probe, and wherein an hourglass shape of the nozzle increases a speed of the shock wave at an output opening of the nozzle; and aspirating the multiple pieces of the cataract out of the eye using suction.
