Solution Approach 1:

The patent changes the electrical parameters by using bipolar electroporation with specific pulse configurations (high voltage, short duration pulses) that enable effective nerve modulation while minimizing thermal damage to blood vessels. The parameter optimization includes controlling pulse width, frequency, and amplitude to achieve therapeutic effects without causing coagulum formation.

Inventive Principle:

Solution Approach 1:

The patent applies local quality by concentrating the electroporation energy precisely at the target neural structures in the renal area while preserving surrounding tissue architecture. The bipolar electrode configuration creates a localized electric field that affects only the intended tissue, leaving blood vessels and other structures intact.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses dynamic pulse delivery with varying amplitude and duration to achieve effective electroporation while monitoring and preserving tissue architecture. The system adapts pulse parameters in real-time to maintain therapeutic efficacy without causing excessive tissue damage or altering tissue structure.

Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent employs periodic electroporation pulses with specific frequency and duty cycle that enable effective neural modulation while allowing tissue recovery between pulses. This periodic action prevents continuous heating and reduces the risk of coagulum formation that occurs with conventional continuous or high-duty-cycle stimulation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The bipolar electrode configuration acts as an intermediary that delivers electrical energy through a controlled pathway, focusing the electric field between the two electrodes and minimizing interaction with blood vessels. This intermediary approach prevents direct energy deposition into blood vessels, reducing coagulum formation risk.

Inventive Principle:
Principle #24Intermediary (Mediator)
