Implantable cardiac resynchronization pace-making defibrillator of His-Purkinje system

Abstract

The invention provides an implantable cardiac resynchronization pace-making defibrillator of a His-Purkinje system. The implantable cardiac resynchronization pace-making defibrillator has two models FD-F and FD-1. The FD-F is provided with an F mark, a His-Purkinje F IS-1 jack, right ventricular and right atrium IS-1 jacks, two suture fixing holes, superior vena cava and right ventricular DF-1 jacks, a left ventricular IS-1 jack, six electrodes, a communication coil, a pace-making circuit, a battery, a shell, a capacitor, a sealing groove and the like. The F mark is convenient to identify beside the His-Purkinje F IS-1 jack. Compared with the model FD-F, the model FD-1 has the advantages that one jack and one electrode are omitted, and the remaining structure and the connection mode are the same as those of the model FD-F. The defibrillator can adjust the pace-making sensing function of the F jack, is used for His-Purkinje mediated cardiac resynchronization pace-making defibrillation,can be specially used for His-Purkinje resynchronization pace-making defibrillation, and can also be used for wide QRS and left ventricle electrodes to jointly participate in resynchronization pace-making defibrillation treatment. The defibrillator is suitable for different implantation connection requirements, and related complications caused by excessive electrodes in a bag are reduced.

Description

technical field [0001] The invention belongs to medical equipment, and relates to an implantable cardiac resynchronization pacing defibrillator of the Hipster system, which is a heart synchronization pacing defibrillator for heart failure combined with a wide QRS Hipster system. It is a kind of cardiac resynchronization pacing defibrillation device used for hippu resynchronization pacing defibrillation or wide QRS combined with left ventricular electrode fusion pacing in the hippo electrode jack. Background technique [0002] Cardiac resynchronization pacing therapy is an important treatment for heart failure with wide QRS. Left ventricular electrodes are implanted in a special position in the coronary vein, that is, commonly used biventricular pacing (BVP). BVP can partially correct heart failure combined with complete left bundle branch block (LBBB), improve cardiac synchronous contraction, and improve cardiac function, but there is still a 30% non-response rate; at the sa...

AI Technical Summary

Problems solved by technology

[0003] Therefore, the current treatment status of cardiac resynchronization pacing and defibrillation devices in the market has the following problems: 1. The effect of conventional BVP cardiac synchronization is limited, and the therapeutic effect is affected by the anatomical phrenic nerve; There is no HOT-CRT dedicated cardiac resynchronization pacing and defibrillator; 3. HOT-CRT treatment can increase the synchronization effect and treatment response, but due to the lack of dedicated jack Problems such as socket wire embedding and possible clinical perception problems

4. In the CRT-D model, the HP electrode is connected to the left ventricle hole, and the left ventricle electrode is connected to the right ventricle hole, which leads to misdischarge problems due to far-field sensing problems.
