AI Technical Summary

Technical Problem

Most of the artificial heart valves with anchors in the prior art need to be hardly connected and released through inserts, locks, guides, etc., resulting in the anchor being too long, the valve stent system structure is complex, and the manufacturing process requirements are high.

Method used

A valve including a stent body, an anchor and a connecting wire is designed. The anchor has a locking state and an expanded state. Through the cooperation of external cues and thread knots, the flexible movement and release of the anchor is achieved, reducing stimulation to blood vessels.

Benefits of technology

This design reduces the stimulation of the anchor to the blood vessels, simplifies the structure of the valve stent system, reduces the complexity and cost of the manufacturing process, and improves the flexibility and safety of the valve implantation.

Abstract

The invention provides a valve and a valve conveying device.The valve comprises a support body, an anchoring piece and a plurality of connecting wires, the anchoring piece comprises an anchoring clamping jaw and a plurality of self-locking units arranged at the distal end of the anchoring clamping jaw, and at least one self-locking unit is provided with a limiting groove; one end of any connecting wire is connected with the support body, and the other end of the connecting wire is slidably connected with the anchoring clamping jaw. Wherein the anchoring piece has a locking state and an expansion state; in a locking state, the self-locking units are mutually connected to form a ring shape, and a knot on the external cable is suitable for abutting against the limiting groove so as to pull the valve to move; in the expansion state, the self-locking units are separated from one another, and the thread knots on the threads are separated from the limiting grooves, so that the situation that an extension arm is arranged at the telecentric end of the anchoring part can be avoided, the anchoring part is released through the threads, stimulation of the anchoring part to the blood vessel is reduced, and normal blood flow in the implantation process cannot be affected.
