Patent ID: 8142424

Claim:
A surgical probe, comprising: a relatively short shaft defining a distal portion and a proximal portion, the distal portion comprising a multi-lumen support structure and a mandrel within a central lumen defined by the multi-lumen support structure, a distal end of the mandrel being secured to a distal tip member, the distal tip member being secured to a distal end of the support structure; an inflatable cryogenic element attached to and positioned around the multi-lumen support structure such that a fluid transmission space is defined between an inner surface of the inflatable cryogenic element and an outer surface of the multi-lumen support structure; and at least one temperature sensor positionable between a portion of the inflatable cryogenic element and a portion of the tissue surface to measure a temperature of the tissue during cryoablation of the tissue, the at least one temperature sensor being connected to at least one signal wire extending through a signal wire lumen defined by the multi-lumen support structure.
