SYSTEM AND METHOD FOR DELIVERING ENERGY TO TISSUE

摘要

Methods and apparatus for treating a patient include an ablation device for ablating a target tissue of a patient. The device includes a housing having proximal and distal ends, and an energy source adjacent the distal end of the housing. The energy source comprises an active portion and an inactive portion surrounded by and extending continuously within the active portion. The active portion comprises a first solid material and is configured to emit ablation energy towards the target tissue when the energy source is energized to create a partial or complete zone of ablation in the target tissue. The inactive portion comprises a second solid material different from the first solid material and does not actively emit energy when the energy source is energized.

主权项

1. A device for ablating a target tissue within a patient, said device comprising:
a housing having a proximal end and a distal end, the housing dimensioned to be positionable within the patient; and an energy source adjacent the distal end of the housing, the energy source comprising an active portion and an inactive portion, the active portion comprising a single, continuous active portion and the inactive portion surrounded by and extending continuously within the active portion, wherein the active portion comprises a first solid material and is configured to emit ablation energy towards the target tissue when the energy source is energized to create a partial or complete zone of ablation in the target tissue, and wherein the inactive portion comprises a second solid material different from the first solid material and does not actively emit energy when the energy source is energized.
