Solution Overview

Problem

Existing anchorage devices for implantable medical devices require multiple sizes to accommodate different device dimensions, necessitating a large inventory for medical practitioners.

Innovation Solution

A customizable anchorage device with a substrate that can be folded and adjusted to create pockets of varying sizes by selectively removing nonstick material from adhesive bonding areas, allowing a single device to fit multiple device sizes, and optionally incorporating hemostatic and active pharmaceutical agents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple different size anchorage devices are provided to accommodate different size implantable medical devices, then the compatibility with various device sizes is improved, but the device complexity and inventory requirements increase

Engineering Contradiction:
Improvecompatibility with various device sizesVSAvoidinventory requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The anchorage device is divided into multiple bonding areas (first bonding area, second bonding area, third bonding area) that can be selectively engaged. This segmentation allows a single device to be configured in multiple ways to accommodate different implantable medical device sizes, eliminating the need for multiple different sized devices in inventory.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The anchorage device is designed with multiple bonding areas and removable nonstick materials that enable a single universal device to accommodate various sizes of implantable medical devices. The device can be configured differently by selectively removing nonstick material from different bonding areas, making it multi-functional rather than requiring separate specialized devices for each size.

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

2Device complexity

If a single anchorage device design is used for all implantable medical devices, then the device complexity is reduced, but the adaptability to different device sizes deteriorates

Engineering Contradiction:
Improvedevice design simplicityVSAvoidcompatibility with various device sizes
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The anchorage device incorporates dynamic elements including removable nonstick materials and selectively engageable bonding areas. This allows the device to be dynamically reconfigured during use to match different implantable medical device sizes, maintaining simplicity in the base design while enabling adaptability when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different bonding areas (first, second, third bonding areas) are positioned at different locations along the substrate, allowing local engagement or disengagement of specific bonding regions. This local quality approach enables a single device design to adapt to different sizes by selectively activating only the necessary bonding areas for each specific application.

Inventive Principle:
Principle #3Local quality

3Strength

If the substrate is made rigid to maintain structural stability, then the strength is improved, but the ease of customization to create different pocket sizes deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidcustomizability
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The substrate is designed as a flexible structure that can be folded along the longitudinal axis to create pockets of varying sizes. This flexible shell approach maintains sufficient structural stability through the bonding areas while enabling easy customization by folding and selective bonding, eliminating the need for rigid structures that would be difficult to customize.

Inventive Principle:
Principle #30Flexible shells and thin films
