Abstract:
1. A system for treating a target tissue of a patient, said system comprising: a handpiece having a size and a shape suitable for being supported in a hand of an operator, and at least one cooling fluid supply path disposed in the handpiece; a probe detachably coupled to the handpiece so as to be replaceable with respect to the handpiece, the probe comprising a probe body and an array of tissue penetrating needles extending distally from the probe body, wherein each tissue penetrating needle of the array of tissue penetrating needles comprises a proximal portion, a distal portion, a lumen extending distally from the probe body, a supply tube extending distally from the probe body within the lumen, the supply tube being detachably and fluidly coupled to the at least one cooling fluid supply path, and comprising a sealed and sharpened distal end insertable into the target tissue of the patient through a skin surface, wherein each tissue penetrating needle of the array of tissue penetrating needles has a size suitable for insertion through the skin surface without leaving a visible scar following removal thereof; and a cooling fluid source coupled to the at least one cooling fluid supply path, such that when cooling is initiated, cooling fluid flows into the lumens of the array of tissue penetrating needles so as to cool the target tissue below the skin surface to remodel the target tissue, wherein the supply tube comprises a fused silica supply tube.
