Solution Overview

Problem

Current implantable medical devices (IMDs) lack effective methods for storing and retrieving patient-specific anatomical images, which are crucial for precise therapy delivery and monitoring, as they typically store image data rather than graphics processing data that can be used to render images, leading to inefficiencies in data storage and rendering processes.

Innovation Solution

The techniques involve storing graphics processing data associated with implantable medical devices, allowing for the generation of patient-specific images by applying this data during a rendering process, enabling clinicians to view and adjust therapy delivery more accurately without performing the rendering process on the device itself.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If image data is stored in the implantable medical device, then complete patient-specific anatomical images can be retrieved, but data storage requirements and device complexity increase

Engineering Contradiction:
Improveimage data completenessVSAvoiddata storage requirements
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts only the essential geometric and positional parameters needed to reproduce anatomical images, storing them as compact graphics processing data in the implantable device while leaving the full rendering capability in external systems. This separation reduces the data storage burden on the implanted device while preserving complete image reconstruction capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of storing complete image data and processing it locally in the implantable device, the patent inverts the approach by storing minimal graphics processing data and performing the computationally intensive rendering process externally. This reversal significantly reduces device complexity and storage requirements.

Inventive Principle:
Principle #13The other way round (Inversion)

2Device complexity

If graphics processing data is stored instead of image data, then data storage requirements are reduced, but the device must not be configured to perform rendering process

Engineering Contradiction:
Improvedata storage requirementsVSAvoidrendering capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent makes the external programming device serve multiple functions: it stores the graphics processing data, performs the rendering process, and displays the resulting images. This multi-functionality compensates for the implantable device's lack of rendering capability, maintaining overall system versatility while reducing implantable device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If patient-specific anatomical images are stored and retrieved, then therapy delivery accuracy is improved, but data transfer time and privacy concerns increase

Engineering Contradiction:
Improvetherapy delivery accuracyVSAvoiddata transfer time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent extracts only the critical geometric parameters needed for accurate therapy delivery and stores them as compact graphics processing data in the implantable device. This extraction reduces data transfer time while preserving the precision needed for accurate anatomical image reconstruction and therapy planning.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

In one example, a device includes a telemetry module configured to retrieve graphics processing data from a device that is not configured to perform a rendering process using the graphics processing data and that is associated with delivering therapy to a therapy target of a patient, and a control unit configured to apply the graphics processing data while performing the rendering process to generate an image of an anatomical feature of the patient, wherein the anatomical feature comprises the therapy target for an implantable medical device (IMD), and to cause a display unit of a user interface to display the image, wherein the image of the anatomical feature is specific to the patient. The graphics processing data may include a list of vertices or a transform to be applied to a non-patient-specific anatomical atlas. The data may also include a location of a therapy element of the IMD.
