Abstract
A probe for performing an ablation treatment includes a shell defining an outer surface and a cryogen supply conduit positioned in the shell. The probe also includes a flexible circuit positioned on at least a portion of the outer surface of the shell. The flexible circuit includes at least one radio frequency (RF) emitter for delivering RF energy to a target tissue.
Claims19
A probe for performing an ablation treatment comprising:
- a shell defining an outer surface;
- a cryogen supply conduit positioned in the shell;
- and a flexible circuit board comprising a flexible substrate and a plurality of measurement points coupled to the flexible substrate, wherein the flexible substrate is positioned on at least a portion of the outer surface of the shell, and wherein the outer surface of the shell is exposed between portions of the flexible substrate.
A method comprising:
- delivering a cryogen to a probe to perform a freezing cycle of an ablation treatment;
- obtaining measurement data from one or more measurement points mounted on a flexible substrate of a flexible circuit, the flexible substrate positioned on an outer surface of the probe, wherein the outer surface of the probe is exposed between portions of the flexible substrate;
- and delivering a radio frequency (RF) signal to an RF emitter on the flexible circuit.
