AI Technical Summary
Technical Problem
Catheters used to deploy stents suffer from kinking, lack of flexibility in navigating curved regions, and tubular wall damage during deployment, particularly in treating cerebral venous sinus stenosis.
Method used
A catheter tube design featuring a dual-layer reinforcement structure with a coiled wire and braided wire assembly, combined with a smooth inner conduit and hydrophilic outer layer, to resist radial deformation and facilitate precise deployment of medical devices, such as stents, while minimizing vessel trauma.
Benefits of technology
The catheter tube maintains a circular cross-sectional shape, reduces vessel trauma, and enhances navigation and visualization, enabling accurate placement of medical devices like stents in complex anatomies.

Abstract
A catheter tube (102) includes an inner conduit (108) and a reinforcement structure (112). The reinforcement structure includes a coiled wire (118) surrounding the inner conduit and a braided wire assembly (120) surrounding the coiled wire. The reinforcement structure is configured to cause the inner conduit to resist radial deformation as a medical device is moved through the inner conduit. A medical intervention system includes the example catheter and an example medical device that can be deployed and implanted using the catheter (100).
