Patent ID: 7500973

Claim:
A modular cryoablation system for performing endometrial ablation, comprising: an elongated tubular cannula having a proximal end, a distal end, and a longitudinal axis; a probe tip comprising a center tube having an internal fluid path and at least two extensions that are each expandable and retractable outwardly relative to the longitudinal axis of the cannula and that each comprise an internal fluid path that is in fluidic communication with the internal fluid path of the center tube, wherein the probe tip is coupled to the distal end of the cannula, and wherein each of the extensions comprises a first end that extends from a distal end of the center tube and a second end spaced from the first end; a probe handle extending from the proximal end of the cannula and in fluidic communication with the internal fluid path of each of the extensions through the cannula and the center tube; and a source of compressed refrigerant fluidly connected to the probe handle.
