  • Device for neurocryo analgesia and anesthesia
    Patent number: 7458968
    Abstract: A catheter system and method for selectively cooling or freezing target neuronal tissue to induce lesions along the neuroaxis and produce cryoanalgesia by impairing nerve conduction of the targeted neuronal tissue. The system includes a catheter that has cryogenic capability for variable cooling or freezing of neuronal tissue. The catheter also includes temperature sensing and electrodiagnostic capabilities. A pressurized fluid source is included for inflating a portion of the catheter body. The system includes electrodiagnostic equipment for stimulating and monitoring sensory evoked potentials in the patient. The method involves placement of the catheter tip in the subarachnoid space of the spinal canal and location of the tip on the neuronal target using imaging and electrodiagnostic techniques.
