Solution Overview

Problem

Conventional nerve ablation procedures often cause undesirable damage to superficial tissues due to the shallow anatomical location of nerves, leading to scarring and disruption of neighboring nerves and blood vessels.

Innovation Solution

A treatment probe with an elongated body member and a needle portion, equipped with at least one electrode and one fluid port, is used to deliver electrical energy and a tumescent fluid, protecting superficial tissue planes from heat damage during nerve ablation by positioning the electrode away from the fluid ports to ensure targeted energy application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrical energy is applied to a target nerve for nerve ablation, then nerve conduction is interrupted to treat neuromuscular defects, but superficial tissue planes overlying the target nerve suffer inadvertent heat damage

Engineering Contradiction:
Improvenerve ablation effectivenessVSAvoidheat damage to superficial tissue
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary action by delivering tumescent fluid to the superficial tissue planes before applying electrical energy for nerve ablation. This pre-treatment creates a protective barrier that insulates the superficial tissues from subsequent thermal damage while allowing the electrical energy to effectively ablate the target nerve.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The tumescent fluid serves as an intermediary substance between the electrical energy source and the superficial tissue planes. It acts as a thermal insulator that mediates the interaction, allowing the electrical energy to reach the target nerve while preventing harmful heat transfer to the overlying superficial tissues.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If electrical energy is applied to a target nerve for nerve ablation, then nerve conduction is interrupted, but unwanted scarring and tissue disruption occur

Engineering Contradiction:
Improvenerve conduction interruptionVSAvoidscarring and tissue disruption
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The tumescent fluid is delivered in advance to the treatment site before electrical ablation occurs. This preliminary fluid delivery prepares the tissue environment by creating a protective barrier that reduces thermal spread, thereby minimizing collateral tissue disruption and scarring while maintaining effective nerve conduction interruption.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent converts the potentially harmful thermal energy that would cause scarring into a beneficial effect by using the tumescent fluid to contain and direct the heat. The fluid transforms the uncontrolled thermal damage into a controlled process that achieves nerve ablation while protecting surrounding tissues from scarring.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
