US Patent 10888366 Cryogenic blunt dissection methods and devices

A point of incision is created within tissue, the tissue having a temporoparietal fascia-deep temporoparietal fascia layer (TPF-sDTF) beneath skin and a temporal branch of a target nerve extending along a portion of the TPF-sDTF, the point of incision being laterally displaced from the target nerve. A cryogenic probe having a distal tip extending from an elongated body is inserted into the point of incision. The TPF-sDTF is bluntly dissected using the cryogenic probe such that a treating portion of the cryogenic probe is directly adjacent to a first treatment portion of the target nerve. The cryogenic probe is activated to create a first treatment zone at the first treatment portion of the target nerve to cause a therapeutic effect.
