Embodiment approach

[0017] Please refer to FIG. 1 , which is a schematic diagram of a potential heart location of an implanted device. The wireless cardiac pacemaker 10 is implanted in the right ventricle 11 through the tricuspid valve through the right atrium 13 through the special transmission equipment, and the electrodes are placed in the endocardium to send pulses to stimulate cardiac pacing. If the clinical situation occurs: the patient at the implantation site suffers from myocardial necrosis and myocardial incrustation, as shown in the dotted circle frame in Figure 1(b), electrodes 2, 3, and 4 will not work, but there is no need to re-implant at this time , No. 1 electrode can play a pacing effect.

[0018] Please refer to the schematic diagram of the multi-electrode wireless cardiac pacemaker invented by this patent figure 2 . The implantable wireless cardiac pacemaker 10 includes a battery 15 , a circuit 16 , a hook-shaped fixing part 17 , and electrodes 18 installed on the fixing par...

Abstract

The invention discloses a controllable wireless cardiac pacemaker system with multi-electrode pacing, which belongs to the field of electrical stimulation medical devices. The wireless pacemaker system has four or more fixed hooks, the pacing electrode is positioned on the anchoring hooks of the implant device, as long as one of the fixation hooks is punctured in the myocardium, it can function asa pacing. The pacemaker system has an electrode 'compensation' function, and when a single electrode is lost, the other electrode is controlled to be used for pacing without performing a second operation. In addition, the pacemaker system employs a chip (e. g., 74 LS148 and the like.) that can control the number of uses of the electrodes remotely according to the actual clinical situation of thepatient, achieve simultaneous stimulation of the four electrodes, or three electrode stimulation, or both electrode stimulation, or any of the electrode stimulation, and the stimulation intensity is adjustable. The system of the invention increases the probability of the electrode targets to contact the myocardium, reduces the risk of perforation during implantation of the pacemaker, reduces the number of re-implantation of the myocardial necrosis patient, prolongs the service life of the implantation device, and the simulation intensity varies according to patients, and it has great referencevalue and application value to the active implantation device.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a multi-electrode pacing implantable in the body and an externally adjustable wireless cardiac pacemaker system. Background technique [0002] A cardiac pacemaker is an electronic device that sends out electrical pulses through a pulse generator, conducts them through wire electrodes, stimulates the myocardium to excite and contract the heart, and is implanted in the patient's body. It is mainly used to treat arrhythmia and other diseases. Every year, nearly 250,000 pacemakers are implanted in China, and 700,000 pacemakers are implanted worldwide. With the continuous research and development of the molding process, the pacemaker has developed from a wired pacemaker to a wireless pacemaker, from a volume of 9.7cm 3 to 0.8cm 3 Miniaturization development. [0003] Leaded pacemakers have frequent complications caused by leads, such as lead dislocation, infection, perf...
