Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing implant delivery methods often require invasive procedures, which can cause significant tissue damage and complications, and there is a need for minimally invasive techniques that allow for the delivery of implants into subcutaneous and soft-tissue implant pockets while maintaining their functionality.

Innovation Solution

Development of compressible implants that can be reconfigured from a compressed state for delivery through minimally invasive incisions to an uncompressed state within implant pockets, with specific dimensions and features to ensure proper positioning and functionality, including therapeutic agent delivery, vascularization, and neurostimulation capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional implant delivery methods are used, then implants can be delivered into implant pockets, but invasive procedures cause significant tissue damage and complications

Engineering Contradiction:

Improvetissue damageVSAvoiddelivery method

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The implant is compressed into a smaller configuration that can be nested within a delivery device or catheter, allowing it to pass through minimally invasive incisions. The implant is then deployed from this nested state into its functional configuration within the implant pocket, resolving the contradiction between minimal incision size and implant functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The implant transitions from a static compressed state during delivery to a dynamic expanded state within the implant pocket. This dynamic transformation allows the same implant structure to satisfy both the minimal incision requirement during delivery and the functional size requirement within the implant pocket.

Inventive Principle:

Principle #15Dynamics

2Object-affected harmful factors

If implants are compressed for minimally invasive delivery, then tissue damage is reduced, but the implant must be reconfigured to maintain functionality within the implant pocket

Engineering Contradiction:

Improvetissue damageVSAvoidreconfiguration mechanism

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The implant utilizes changes in physical parameters such as pressure, temperature, or shape memory properties to transition from its compressed delivery configuration to its functional deployed configuration. This parameter-based transformation simplifies the reconfiguration mechanism compared to complex mechanical assembly systems.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The implant is designed to automatically reconfigure from its compressed to functional state through self-actuating mechanisms such as elastic recovery, shape memory effects, or pressure-driven expansion, eliminating the need for complex external reconfiguration devices or manual assembly procedures.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If minimally invasive incisions are used, then tissue damage is reduced, but the incision size is limited in terms of allowing implant passage

Engineering Contradiction:

Improvetissue damageVSAvoidincision size

Core Design Contradiction:

Object-affected harmful factorsVSLength of moving object

Solution Approach 1:

The implant is compressed in the dimensional direction perpendicular to its functional plane, allowing it to pass through a small incision and then expand back to its functional size within the implant pocket. This dimensional transformation resolves the contradiction between incision size and implant size.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Principle #7Nested doll (Nesting)

AI summary

Systems and methods involving implants positioned within implant pockets through minimally invasive entrance incisions, along with related neurostimulatory implants. In some implementations, implants may be folded, rolled, or otherwise compressed to fit within subcutaneous implant pockets, after which they may be decompressed to fit within an implant pocket having one or more dimensions substantially larger than the entrance incision. Such implants may be used for a variety of purposes, including generating electrical energy for various other implants, including neurostimulatory implants located throughout the body.
