Solution Overview

Problem

Current occlusion devices for body vessels, such as plugs or multiple coils, are inefficient, costly, and time-consuming for placement, particularly in arterial and venous embolization procedures.

Innovation Solution

An occlusion device comprising a sleeve with tentacles that reverse direction to occlude the interior in response to fluid flow, combined with a self-expanding frame for deployment and retrieval, which can be delivered and retrieved using a specialized assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If plugs or multiple coils are used for occlusion, then occlusion can be achieved, but placement is inefficient, costly, and time-consuming

Engineering Contradiction:

Improveplacement efficiencyVSAvoidprocedure time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

Multiple coils are merged into a single integrated occlusion device with a sleeve and tentacle structure, allowing one device to perform the occlusion function that previously required multiple separate coils or plugs

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The occlusion device is segmented into functional components (sleeve, tentacles, frame) that can be deployed in a controlled sequence, with tentacles extending to occlude the vessel interior while the frame provides structural support

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If a self-expanding frame with tentacles is used, then deployment and retrieval are simplified, but device complexity increases

Engineering Contradiction:

Improvedeployment easeVSAvoiddevice structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The device transitions from a compressed delivery state to an expanded functional state through fluid flow activation, with tentacles dynamically extending and reversing direction to occlude the vessel interior

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The self-expanding frame automatically deploys and positions the tentacles in response to fluid flow without requiring additional manual manipulation, and the retrieval mechanism uses the same fluid flow to collapse and retrieve the device

Inventive Principle:

Principle #25Self-service

AI summary

An occlusion device and a method of occluding a body vessel with the occlusion device are provided. The occlusion device has a sleeve that extends from a first end to a second end. The sleeve has an interior that extends to an opening at the first end. The occlusion device has tentacles that are attached to the first end and extend away from the sleeve. The tentacles reverse direction and extend into the interior to occlude the interior in response to fluid flowing toward the opening. A frame is attached to the first end of the sleeve.
