Embodiment approach

[0021] 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 a special transmission device, and the electrodes are placed against 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.

[0022] Please refer to the schematic diagram of the multi-electrode wireless cardiac pacemaker invented by this patent figure 2 , the schematic diagram of interconnection of wireless pacemaker components is shown in image 3 . The implantable wireless cardiac pacemaker 10 includes a casing...

Abstract

The invention discloses a multi-electrode pace-making modulatable wireless cardiac pacemaker system and a manufacturing method. The wireless pacemaker system comprises a closed shell, a plurality of fixing hooks arranged on the shell, at least one or more stimulation electrodes arranged on the fixing hooks, a plurality of pace-making and sensing passage modules arranged in the shell and a battery.The pacemaker system has an electrode 'compensation' function, wherein when a single electrode is disabled, the other electrode can be controlled in vitro for pace making without a second surgery. Inaddition, the pacemaker system can remotely control the use number of the electrodes according to an actual clinical condition of a patient. The system increases the probability of an electrode target contacting the myocardium, reduces the risk of perforation when the pacemaker is implanted, reduces the frequency of re-implantation for a patient with myocardial necrosis, and prolongs the servicelife of the implant device, the stimulation intensity can also be different for different patients, and the referential significance and application value for active implant devices are great.

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...
