AI Technical Summary
Existing self-expanding valve prostheses suffer from non-uniform diameter release due to the properties of nickel-titanium alloys during deployment, resulting in unfriendly valve prosthesis displacement and positioning, and requiring special loading conditions.
Design a wire-controlled support bracket. By setting multiple layers of wave rods and connecting holes on the bracket and using a pull wire for constraint, it can achieve equal-diameter loading, release and retrieval. A conveying device is used for loading and conveying the wire-controlled support bracket.
It achieves isodiameter release and retrieval of the valve prosthesis, improving the stability and success rate of the surgery, simplifying the operation process, and reducing the impact on coronary blood flow.
