Abstract
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.
Claims36
A method comprising:
- creating a point of incision within tissue, the tissue comprising 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 TB-FN;
- inserting a cryogenic probe having a distal tip extending from an elongated body into the point of incision;
- bluntly dissecting the TPF while moving the cryogenic probe over the sDTF to place a treating portion of the cryogenic probe adjacent to a first treatment portion of the target nerve;
- and
- activating the cryogenic probe to create a first treatment zone at the first treatment portion of the target nerve to cause a therapeutic effect.
A method comprising:
- creating a point of incision within tissue, the tissue comprising a temporoparietal fascia-deep temporoparietal fascia layer (TPF-sDTF) beneath skin and a temporal branch of a facial nerve (TB-FN) extending along a portion of the TPF-sDTF, the point of incision being laterally displaced from the TB-FN;
- inserting a cryogenic probe having a distal tip extending from an elongated body into the point of incision;
- bluntly dissecting the TPF-sDTF using the cryogenic probe such that a treating portion of the cryogenic probe is directly adjacent to the TB-FN;
- and
- repeatedly moving and activating the treating portion of the cryogenic probe such that a plurality of treatment zones is created across the TB-FN.
A system comprising:
- a probe body;
- an elongated probe having a blunt distal tip;
- and
- a cryogen supply tube extending within the elongated probe, wherein the elongated probe and supply tube are configured to resiliently bend.
A method comprising:
- creating a point of incision within tissue, the tissue comprising skin, a layer of soft tissue and a layer of resilient tissue,
- inserting a cryogenic probe having a distal tip extending from an elongated body into the point of incision;
- bluntly dissecting the soft tissue using the cryogenic probe such that a treating portion of the cryogenic probe is directly adjacent to the resilient layer;
- advancing the cryogenic probe along the resilient layer;
- and
- repeatedly moving and activating the treating portion of the cryogenic probe such that a plurality of treatment zones is created across a nerve adjacent to the resilient layer.
