What changed

This document is a publication of a new patent application, US20260083491A1, filed by Pacira CryoTech, Inc. The application describes a novel method and device for cryogenic blunt dissection of tissue, particularly the temporoparietal fascia-deep temporoparietal fascia layer (TPF-sDTF). The technique involves creating an incision laterally displaced from a target nerve, inserting a cryogenic probe, and using it to dissect tissue and apply cryogenic treatment directly adjacent to a portion of the target nerve to achieve a therapeutic effect.

As this is a patent application, it does not impose immediate regulatory obligations or compliance deadlines on regulated entities. However, it signals potential future developments in medical devices and therapeutic techniques within the healthcare sector. Companies involved in prosthetics, medical devices, or surgical procedures should monitor the progress of this patent application and related technologies for potential competitive or licensing implications.

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.
