This invention discloses a coherent electrical stimulation method for idiopathic scoliosis combined with exercise therapy, belonging to the field of electrical stimulation methods for idiopathic scoliosis. It aims to address the problem of how to dynamically adjust stimulation parameters based on individual differences to improve treatment efficacy. The method includes acquiring raw image sequences of the patient's spine through MRI scans, preprocessing the raw image sequences to construct a three-dimensional geometric model of the spine, configuring simulated electrical property parameters for the tissue structures, and then adding coherent electrical surface electrodes to the model. The electrode placement area on the three-dimensional geometric model of the spine is initially defined, and a coherent electrical stimulation signal is generated using a function generator. A comprehensive evaluation index value is calculated through finite element analysis to dynamically adjust the coherent electrical stimulation signal. Based on the coherent electrical stimulation signal parameters and its comprehensive evaluation index value, a coherent electrical stimulation scheme is determined, and ultrasound-guided technology is used to locate the electrode positions and implement coherent electrical stimulation therapy.

This invention proposes a mitral valve capture mechanism for transcatheter interventional therapy, comprising: a capture unit, sleeved outside a control rod and located behind a clamping device, comprising: a base with an axially extending through-hole for the control rod to pass through, the front end of which is connected to a plurality of circumferentially distributed shape memory alloy units; a rigid unit, correspondingly arranged and connected to the shape memory alloy units, comprising an anterior rigid plate and a posterior rigid plate, wherein the anterior and posterior rigid plates do not contact each other, nor does the posterior rigid plate contact the base; a limiting ring, located in front of the shape memory alloy units and connected to the anterior rigid plate; a first cable control unit and a second cable control unit. This invention can effectively solve the problem of valve floating due to blood flow during mitral valve edge-to-edge repair, leading to clamping failure.

The application discloses a ventricular support drainage device, which comprises a drainage tube, a self-expanding support bracket, a delivery tube and a support strip. The self-expanding support bracket is arranged outside the drainage tube, and the support bracket in an expanded state is used for supporting the ventricular wall. A small protrusion is arranged inside the support bracket, and the small protrusion is in close contact with the drainage tube in a compressed state. The delivery tube is sleeved outside the drainage tube and the support bracket, and is used for maintaining the drainage tube and the support bracket in the compressed state. The support strip is arranged inside the drainage tube in the compressed state, and is used for supporting the whole structure during delivery. The support strip is used for delivering the drainage tube and the support bracket compressed in the delivery tube to a drainage position under the support of the support strip, and maintaining the position of the drainage tube unchanged when the delivery tube is withdrawn. The support strip is blocked at the first end of the drainage tube. The arrangement guarantees that the drainage device is effectively delivered, and the support bracket plays a supporting role and the drainage tube plays a drainage role after being delivered.
