Solution Overview

Problem

Current anchorage devices for implantable medical devices face challenges in managing postoperative bleeding, particularly in Cardiac Implantable Electronic Device (CIED) procedures, where pocket hematomas are common and increase the risk of infection, requiring a large inventory of devices with varying hemostatic agents to accommodate different types of devices and patient sizes.

Innovation Solution

A kit comprising an anchorage device with a mesh substrate coated with a polymer that elutes an active agent, separate from a hemostatic agent, which can be delivered before, during, or after implantation to reduce bleeding and infection, featuring a soluble polymer and active agents like tranexamic acid, collagen, and antibiotics to control bleeding effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hemostatic agents are incorporated into anchorage devices, then bleeding control is improved, but device complexity and inventory requirements increase

Engineering Contradiction:
Improvebleeding controlVSAvoidinventory requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent separates the hemostatic agent from the anchorage device into distinct components. The anchorage device contains only the mesh substrate and polymer without embedded hemostatic agents, while hemostatic agents are provided as separate items that can be applied independently. This segmentation allows each component to be standardized and simplifies inventory management while maintaining effective bleeding control through the combination of components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal anchorage device design that can be used with multiple types of implantable medical devices (pacemakers, ICDs, etc.) without requiring device-specific hemostatic agent combinations. The standardized anchorage device paired with separate hemostatic agent options provides multi-functionality across different surgical scenarios while reducing the need for specialized inventory items for each device type.

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

2Reliability

If multiple types of hemostatic agents are used for different device types and patient sizes, then treatment effectiveness is improved, but ease of operation decreases

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidsurgical preparation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By segmenting the hemostatic agents into separate, pre-packaged items rather than incorporating them into the anchorage device, the patent allows surgical teams to select and prepare only the specific hemostatic agents needed for each procedure. This eliminates the complexity of managing multiple anchorage device variants with different hemostatic agents while maintaining the ability to provide effective treatment for different device types and patient sizes.

Inventive Principle:
Principle #1Segmentation

3Reliability

If hemostatic agents are incorporated into the anchorage device, then bleeding control is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvebleeding controlVSAvoidmanufacturing process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent divides the product into separately manufacturable components: the anchorage device (mesh substrate and polymer) and the hemostatic agents. This segmentation allows each component to be manufactured independently using optimized processes, avoiding the complexity of incorporating hemostatic agents during anchorage device manufacturing. The separate components can then be assembled or applied during surgery as needed.

Inventive Principle:
Principle #1Segmentation
