AI Technical Summary
In the existing technology, the release of a double-layer particle-carrying stent requires two delivery systems, which increases the cost of medical device use and operation time. Furthermore, the relative positions of the inner and outer stents are easily affected by human factors, leading to deviations in the release position.
A dual-layer particle-carrying stent delivery device was designed, which adopts an inner and outer cylindrical self-expanding stent. Through the combination structure of guide head, inner tube, inner stent tube and outer stent tube, the dual-layer stent can be released in one insertion into the human body cavity. The control handle and imaging ring ensure accurate release position.
It achieves precise release of the double-layer stent, saves a delivery system, reduces patient costs, shortens operation time, and ensures precise and controllable relative positions of the inner and outer stent layers.
