Introducer Sheath Thrombus-Inducing Coating for Hemostasis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for percutaneously introducing catheters into the body often result in prolonged physical burden on patients due to extended hemostasis times after the introducer sheath is removed.
Innovation Solution
An introducer sheath with a thrombus inducing material disposed on its outer surface, which promotes thrombus formation at the insertion site before removal, reducing the time necessary for hemostasis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a balloon or similar device is used to press the introduction part for hemostasis, then hemostasis can be achieved, but the patient experiences prolonged physical burden
Solution Approach 1:
The patent applies preliminary action by coating the catheter outer surface with thrombus inducing material before introduction. This material promotes thrombus formation at the introduction part beforehand, so that when the catheter is removed, hemostasis occurs more rapidly without requiring prolonged external compression, thereby reducing patient physical burden while maintaining hemostasis effectiveness
Solution Approach 2:
The patent converts the potentially harmful uncontrolled bleeding into a beneficial controlled thrombus formation. By introducing thrombus inducing material that promotes clotting at the introduction part, the natural hemostatic mechanism is enhanced and directed to occur at the desired location and time, transforming the harmful bleeding risk into a beneficial self-hemostasis effect
2Reliability
If hemostasis is performed by prolonged compression of the introduction part, then bleeding can be controlled, but the treatment time is extended
Solution Approach 1:
The thrombus inducing material is applied to the catheter surface before the procedure, preparing the introduction part in advance to promote rapid thrombus formation. This preliminary preparation eliminates the need for prolonged post-removal compression, significantly reducing hemostasis time while ensuring reliable bleeding control
Solution Approach 2:
The patent enables self-service hemostasis by allowing the thrombus inducing material to automatically promote clot formation at the introduction part after catheter removal. This self-hemostatic mechanism eliminates or reduces the need for prolonged manual compression or balloon inflation, thereby shortening treatment time while maintaining hemostasis control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The introducer sheath effectively shortens hemostasis time by promoting thrombus formation at the insertion site, thereby reducing the physical burden on patients.
Implementation Method 1
the formation of the thrombus at the introduction part can be promoted before removing the introducer sheath

AI summary
An introducer sheath is disclosed capable of reducing a physical burden on a patient by shortening a time necessary for hemostasis at an introduction part after removing the introducer sheath percutaneously introduced into a body lumen. The introducer sheath includes a catheter main body, which is percutaneously introduced into a body lumen, a hub, which is connected to a proximal side of the catheter main body, and a tube member which includes a thrombus inducing material M. The tube member is disposed at a proximal side of an outer surface of the catheter main body.
