Abstract
Apparatus for reducing the size of an object disposed in a generally closed fluid medium includes a handpiece having an axis extending from a housing at a proximal end to a probe at an opposing distal end. A reducer at the distal end of the probe is adapted for insertion into the fluid medium where it is rotatable to reduce in size the object. The reducer is configured to create a fluid flow in the fluid medium so that the handpiece can be maintained laterally and axially stationary while the object is moved by the fluid flow into contact with the reducer. An associated method includes the steps of rotating the rotary member at a speed sufficient to reduce the size of the object, and in a manner to produce a flow of the fluid sufficient to move the object into the rotary member.
