Solution Overview

Problem

Implantable medical devices capable of both cardiac and neural stimulation often require different implantation procedures for each type of therapy, leading to inefficiencies and potential operational challenges when only one type of stimulation is initially enabled, necessitating time-consuming lead and sensor configuration determination by physicians.

Innovation Solution

A system and method that enable the implantable medical device or external programming device to automatically determine the lead and sensor configuration through port usage, configuring programmable parameters accordingly, and displaying visual indications to prevent configuration of unsupported therapies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an implantable medical device is programmed with multiple therapy types (cardiac and neural stimulation), then the device can address diverse patient needs, but the configuration process becomes complex and time-consuming requiring physicians to manually determine lead and sensor configuration

Engineering Contradiction:
Improvetherapy type supportVSAvoidconfiguration process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system enables the implantable medical device to automatically determine its own lead and sensor configuration by detecting port usage, eliminating the need for physicians to manually configure parameters. The device self-identifies which therapy types are supported based on physical connections, automatically enabling or disabling corresponding programmable parameters to prevent configuration of unsupported therapies.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The external device accelerates the configuration process by using port usage detection to rapidly determine lead configuration and automatically configure programmable parameters, significantly reducing the time required compared to manual physician determination of each parameter setting.

Inventive Principle:
Principle #38Strong oxidants (Accelerated oxidation)

2Ease of manufacture

If a device capable of both cardiac and neural stimulation is implanted with leads for only one type of therapy, then the implantation procedure is simplified, but the programmable features related to the other therapy type remain active creating operational challenges

Engineering Contradiction:
Improveimplantation procedureVSAvoidoperational correctness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The system continuously monitors port usage to detect which leads are actually connected to the device. Based on this feedback, the system automatically enables or disables programmable parameters corresponding to supported and unsupported therapy types, ensuring that only configurations matching the physical implantation are available for programming.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system proactively prevents configuration errors by disabling programmable parameters for therapy types that are not supported by the implanted leads before the physician can attempt to program them. This preliminary action eliminates the risk of configuring unsupported therapies.

Inventive Principle:
Principle #9Preliminary anti-action

3Measurement precision

If physicians manually determine lead and sensor configuration, then accurate therapy programming is achieved, but valuable patient time is wasted during the configuration process

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidconfiguration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system replaces the manual mechanical process of physician determination with an automated electronic detection system that identifies lead configuration by monitoring port usage. This substitution maintains configuration accuracy while dramatically reducing the time required, as the electronic detection occurs automatically without manual intervention.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs configuration determination automatically during device initialization or connection, before the physician needs to program therapy parameters. This preliminary action eliminates the time-consuming manual determination step while ensuring accurate configuration is established in advance.

Inventive Principle:
Principle #10Preliminary action
