Intracardiac Implants, Pacemakers, Implanted Devices

Abstract

The present application discloses an intracardiac implant and a device for respectively implanting two interconnected implants into two cardiac chambers at one time. The intracardiac implant includes: a cylindrical shell, the shell includes a side wall, a first end and a second end; a first connecting portion disposed at the first end of the shell, used for connecting with the implant device and a hook body arranged on the side wall of the housing, the hook body includes a fixed end on the side wall and a free end extending from the fixed end, wherein the hook body and the side wall Form a clamping structure between the free ends, the free end includes a tip at the top, the tip is used to penetrate the myocardium, and through the clamping between the hook body and the side wall, the heart cavity is implanted fixed on the myocardium. The intracardiac implants, cardiac pacemakers, and implant devices in this application enable the intracardiac implants to be better fixed on the myocardium, the implantation process is safer and easier, and can realize dual-chamber starting without wires. fight.

Description

technical field [0001] The present invention relates to the field of implantable medical devices, and more particularly, to intracardiac implants, miniature leadless cardiac pacemakers and implanted devices. Background technique [0002] The placement of micro-implants in the heart cavity is the latest diagnostic and therapeutic method in modern medicine. Micro-implants in cardiac chambers, including sensors for obtaining parameters such as ECG, blood pressure, blood flow, and blood biochemistry, as well as micro-therapeutic devices for performing treatments such as drug release and cardiac pacing. In order to place the micro-implant into the heart cavity, a transcatheter intervention is required to deliver the implant to a specific location in the heart cavity and fix it to prevent the micro-implant from dislodging or dislodging, causing the implant Complications such as failure or embolism. [0003] Pacemakers are widely used implants in the human body. Today, millions ...

AI Technical Summary

Problems solved by technology

Due to the impact of heartbeat and blood, the wireless miniature pacemaker is easy to detach from the myocardium, shift and move in the heart chamber, causing embolism or poor contact between the electrode and the myocardium, affecting the perception of ECG and pacing effects, and the lack of mesh in the atrium Tissues, using existing fixtures, cannot achieve atrial pacing and cardiac dual-chamber pacing, and it is difficult to guarantee the effect and safety of pacing
