Patent Images
1. A device for releasing a medical workpiece at a target site in a patient'"'"'s body, comprising:
- an elongate member having a distal end;
a piezoelectric member coupled to the elongate member at or near its distal end;
a pair of electrical conducting members, each electrically coupled to the piezoelectric member; and
a medical workpiece coupled to the distal end of the elongate member via a detachable joint, the detachable joint being incorporated into or otherwise operatively coupled with the piezoelectric member, such that vibration energy generated by passing an electrical current through the respective electrical conductors and piezoelectric member causes the workpiece to detach from the elongate member.
