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

Embodiment Construction

[0049] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.

[0050] In the following examples, intracardiac implants are described using a pacemaker as an example. However, it should be understood that the intracardiac implant of the present invention is not limited to a pacemaker, but may be any one selected from a pacemaker, a physiological parameter monitoring device, and a drug supply device.

[0051] figure 1 A schematic diagram of an intracardiac implant 100 according to a first embodiment of the present invention is shown. The intracardiac implant 100 includes a shell 110, a first end 120 at the bottom of the shell, a second end 130 at the top of the shell, a hook 140 arranged on the side wall of the shell, and two hook...

Abstract

The invention discloses an intracardiac implant, and a device and a method for respectively implanting two interconnected implants into two heart cavities at one time. The intracardiac implant comprises a columnar shell. The shell comprises a side wall, a first end and a second end. A first connecting part is arranged at the first end of the shell and is used for being connected with an implantation device. A hook body is arranged on the side wall of the shell. The hook body comprises a fixed end on the side wall and a free end extending from the fixed end. A clamping structure is formed between the hook body and the side wall. The free end comprises a tip located at the top, and the tip is used for piercing the myocardium. Through the clamping effect between the hook body and the side wall, the intracardiac implant is fixed on the myocardium. According to the intracardiac implant, the cardiac pacemaker, the implantation device and the implantation method of the invention, the intracardiac implant can be better fixed on the myocardium. The implantation process is safer and more convenient. Meanwhile, the lead-free and double-cavity pacing can be realized.

Description

technical field [0001] The invention relates to the field of implantable medical devices, more specifically, to an implant in a cardiac cavity, a miniature leadless cardiac pacemaker, an implant device and an implant method. Background technique [0002] Placing micro-implants in the heart cavity is the latest diagnosis and treatment method in modern medicine. Micro-implants in the heart chamber, including sensors used to obtain parameters such as ECG, blood pressure, blood flow, and blood biochemistry, as well as micro-therapeutic devices used to perform treatments such as drug sustained release and cardiac pacing. In order to place the micro-implants into the heart chamber, transcatheter intervention is required to deliver the implant to a specific position in the heart chamber and fix it to prevent the micro-implant from dislodging or falling off, causing the implant Complications such as failure or embolism. [0003] Pacemakers are widely used implants in the human bod...
