Solution Overview

Problem

Current treatments for chronic pain and cosmetic defects, such as wrinkles and cellulite, often involve invasive procedures, systemic side effects, and temporary results, while existing cryogenic techniques face challenges in temperature control and target tissue accuracy.

Innovation Solution

The use of a cryogenic probe with a distal tip for blunt dissection and cooling treatment zones along tissue layers, allowing precise remodeling of target tissues like nerves and muscles, minimizing collateral damage and invasiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments (pharmaceuticals, neurostimulators, neurolysis) are used for chronic pain, then pain relief is achieved, but systemic side effects and invasiveness increase

Engineering Contradiction:

Improvepain relief effectivenessVSAvoidsystemic side effects

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cryogenic probe applies localized cooling directly to the target nerve or tissue, creating a focused treatment zone that eliminates pain without affecting other body systems. This localized approach replaces the systemic side effects of pharmaceuticals with a targeted physical treatment.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The invention replaces pharmacological and electrical treatment systems with a cryogenic cooling system. By using extreme cold to disrupt nerve conduction and promote tissue remodeling, the system achieves pain relief without the need for addictive opioids or systemic medications.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If invasive procedures (surgical implantation, nerve damage) are used for pain treatment, then pain relief is achieved, but recovery time and risk increase

Engineering Contradiction:

Improvepain relief effectivenessVSAvoidrecovery time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The cryogenic treatment is applied in controlled periodic cycles, allowing the tissue to undergo gradual freezing and thawing processes that promote healing. This periodic application enables pain relief while minimizing tissue damage and reducing recovery time compared to surgical interventions.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The invention changes the physical parameter of temperature to achieve therapeutic effects. By controlling the temperature to reach subzero levels locally, the system creates a non-invasive treatment that avoids surgical risks and reduces recovery time while maintaining effective pain relief.

Inventive Principle:

Principle #35Parameter changes

3Temperature

If cryogenic cooling is applied to treat tissue, then temperature control is achieved, but target tissue accuracy and collateral damage control are challenging

Engineering Contradiction:

Improvecooling temperature controlVSAvoidtarget tissue accuracy

Core Design Contradiction:

TemperatureVSManufacturing precision

Solution Approach 1:

The cryogenic probe acts as an intermediary device that delivers controlled cooling from the treatment source to the target tissue. The probe's design includes insulation and positioning features that ensure accurate delivery of cold to the intended target while protecting surrounding tissues from collateral damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system incorporates temperature monitoring and control mechanisms that provide feedback during the cryogenic treatment. This feedback allows real-time adjustment of cooling intensity to maintain precise temperature control and ensure accurate targeting of the intended tissue while preventing excessive cooling of adjacent structures.

Inventive Principle:

Principle #23Feedback

AI summary

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.
