Endoscopic Petal Body for Hemostatic Patch Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for bleeding ulcers in the gastrointestinal tract, such as injection therapies, thermal therapies, and hemostatic powders, are often expensive, time-consuming, and ineffective for larger surface areas, and minimally-invasive procedures to position patches are cumbersome and less accurate.
Innovation Solution
A medical device comprising a handle with a movable body, a cap, and a petal body that transitions between closed and open configurations to deploy a biocompatible hemostatic patch radially outward from the endoscope, allowing for precise positioning and deployment of patches within the GI tract.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional treatments (injection, thermal, mechanical therapies) are used for bleeding ulcers, then hemostasis can be achieved, but the procedures are expensive and time-consuming
Solution Approach 1:
The hemostatic patch is pre-loaded onto the petal body structure within the endoscope assembly before insertion. This preliminary preparation allows the patch to be immediately deployed at the ulcer site without requiring additional preparation time during the procedure, thus reducing overall procedure time while maintaining hemostatic effectiveness
Solution Approach 2:
The patent replaces conventional mechanical and thermal hemostasis methods with a biocompatible patch delivery system that utilizes the endoscope's existing mechanical structure (petal body) to deploy the patch. This substitution eliminates the need for time-consuming injection or thermal therapies while achieving reliable hemostasis
2Reliability
If conventional therapies are applied, then hemostasis can be achieved, but they cannot effectively treat larger surface areas
Solution Approach 1:
The hemostatic patch is designed as a separate, removable component that can be independently sized and shaped to match the ulcer surface area. The patch is coupled to the petal body through a removable connection mechanism, allowing it to be deployed as a discrete unit that can cover larger surface areas more effectively than conventional point-based therapies
Solution Approach 2:
The patent transitions from point-based or small-area hemostasis methods to a patch-based approach that operates in two dimensions. The petal body structure allows the patch to be deployed radially outward, covering a significantly larger surface area at the ulcer site compared to conventional linear or punctual treatment methods
3Duration of action of stationary object
If gastric bypass is used to treat chronic ulcers, then long-term healing can be achieved, but the procedure is more difficult, time-consuming, and costly
Solution Approach 1:
The patent employs a disposable hemostatic patch that is applied directly to the ulcer site and allows natural healing to occur. This approach replaces complex surgical procedures like gastric bypass with a simple, single-use patch application, significantly reducing procedure complexity while still achieving long-term healing through the patch's biocompatible materials and hemostatic properties
Solution Approach 2:
The invention substitutes major surgical intervention (gastric bypass) with a minimally invasive endoscopic patch delivery system. The patch, delivered through the endoscope's petal body mechanism, provides the necessary hemostasis and healing support without requiring complex abdominal surgery, thereby reducing procedure complexity and cost
4Object-affected harmful factors
If minimally-invasive procedures are used to position patches, then tissue damage is reduced, but the procedures are cumbersome and less accurate
Solution Approach 1:
The endoscope assembly integrates multiple functions into a single device: navigation through the GI tract, visualization of the ulcer site, and deployment of the hemostatic patch. The petal body structure serves both as a delivery mechanism and as a positioning platform, allowing precise control of patch placement while minimizing tissue damage through the existing endoscopic access pathway
Solution Approach 2:
The petal body acts as an intermediary structure between the endoscope and the hemostatic patch. It provides a controlled interface that allows the patch to be precisely positioned at the ulcer site while maintaining the minimally-invasive nature of the procedure. The removable coupling mechanism enables accurate placement without requiring complex surgical intervention

AI summary
A medical device may comprise a handle, wherein the handle includes a movable body and a main body; a cap configured to be coupled to a distal end of a scope; a patch, wherein the patch is moveable relative to the cap; and a petal body. The patch may be removably coupled to the petal body. The medical device may further comprise an actuator body coupling the patch to the moveable body such that movement of the moveable body extends the patch from the cap. The petal body may be configured to transition between a closed configuration in which the patch is retracted, and an open configuration in which the patch is extended radially-outward from a central longitudinal axis of the scope.
