Wireless pacemaker conveying catheter device controlled to turn by using memory alloy wires and production method

Abstract

The invention belongs to the field of interventional medical apparatuses, and particularly relates to a wireless pacemaker conveying catheter device controlled to turn by using memory alloy wires anda production method. The conveying catheter device structurally comprises a control handle, a conveying catheter, a specific device at a far end of the catheter and a control system. The wireless pacemaker conveying catheter device is mainly characterized in that electric currents passing through the memory alloy wires are integrally controlled through the handle; the change of a different lengthof each alloy wire is realized to realize a bending function of the conveying catheter; moreover, a bending angle is displayed on a display screen of the control system, so as to realize the digital control of the bending angle, wherein the control system has data recording and uploading function, and can be used for recording and uploading an implantation path of a medical device, so as to optimize the implantation path, wherein the conveying catheter is produced through a way of firstly gluing and then carrying out thermal shrinkage in the production method. The wireless pacemaker conveyingcatheter device can be used for accurately, conveniently and quickly realizing the digital control of the bending function of the catheter, is used for shortening an implantation time and improving implantation safety, and has a better application prospect in the conveyance of a wireless pacemaker.

Description

technical field [0001] The invention belongs to the field of interventional medical devices, and in particular relates to a method for controlling bending and turning by memory alloy wires and a wireless pacemaker delivery catheter device prepared by lamination heat shrinkage technology. Background technique [0002] Cardiac arrhythmia refers to any one or more abnormalities in the site of cardiac rhythm origin and cardiac frequency, rhythm, and impulse conduction. It is one of the common clinical cardiovascular diseases and can be roughly divided into two types: functional and organic. The functional ones are mostly related to emotional agitation, mental stress, autonomic dysfunction, cardiac neurosis, etc.; the organic ones are mostly caused by coronary heart disease, rheumatic heart disease, cardiomyopathy, etc., especially in acute myocardial infarction, which is the cause of death. important reason. Every year, 17 million people die from cardiovascular diseases in the ...

AI Technical Summary

Problems solved by technology

Although there are hundreds of thousands of routine pacemaker implantation operations every year, there are still some obvious deficiencies, such as the corrosion or even disconnection of the connection between the pulse generator and the wire, and the high rate of serious complications related to the wire. Morbidity, aesthetics after implant surgery, etc.
