USPTO Patent Application: Cryo-ablation System for Sympathetic Nervous System Hyperactivity
Summary
The USPTO has published a patent application detailing a cryo-ablation system designed to treat sympathetic nervous system hyperactivity. The system utilizes a catheter with a configurable heat transfer element and deployable temperature probes to measure tissue temperature and optimize ablation.
What changed
This document is a USPTO patent application (US20260083490A1) for a cryo-ablation system intended to treat conditions related to sympathetic nervous system hyperactivity. The application describes a catheter with a heat transfer element that can change shape and deployable temperature probes to measure tissue temperature in real-time. A computational control system uses this data to model isotherm progression and optimize the ablation process, including vessel occlusion during treatment.
As this is a patent application, it does not impose direct compliance obligations on regulated entities. However, it signals potential future technological advancements in the medical device sector, particularly for treatments targeting the sympathetic nervous system. Companies involved in developing or manufacturing medical devices for cardiovascular or neurological applications should be aware of this patented technology.

Abstract
A cryo-ablation system treats conditions associated with sympathetic nervous system hyperactivity using a catheter with a configurable heat transfer element that transitions from a flat delivery profile to deployed configurations including helical shapes. The system includes deployable temperature probes that directly measure tissue temperature at target locations inside or outside blood vessels. A computational control system processes temperature data from multiple sensors and deployable probes to calculate real-time lethal isotherm progression using heat transfer modeling algorithms. The system provides vessel occlusion during treatment and real-time feedback for treatment optimization. Methods include introducing the catheter into a renal artery, deploying the heat transfer element, occluding the vessel, deploying temperature probes to target locations within or outside the vessel, delivering cryogenic temperatures while monitoring probe temperatures, and terminating treatment based on computational analysis of temperature data to achieve target ablation depths.
