Abstract:

A medical device such as a biopsy needle or probe has an integrated piezoelectric transducer. A power source is electrically coupled to the piezoelectric transducer. The power source is configured to generate a signal that causes the piezoelectric transducer to generate heat for cauterizing tissue. A signal analyzer receives a signal from the piezoelectric transducer, or from a sensor integrated into the biopsy needle or probe, to determine the extent of the cauterization.
