Embodiment Construction

[0034] 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.

[0035] 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.

[0036] figure 1 A perspective perspective view of an intracardiac implant 100 according to a first embodiment of the invention is shown. The intracardiac implant 100 includes a shell 101 , clamping parts 102 located at both ends of the shell, a hook body 103 mounted on the shell side, and two electrodes 104 mounted on the side walls...

Abstract

The invention discloses an intracardiac implant and a fixing method thereof. The intracardiac implant comprises a columnar shell, clamping parts and a hook body, wherein the shell has a side wall and two ends, the clamping parts are located at at least one end of the shell and used for being connected with an operation catheter, the hook body is installed on the side wall of the shell and comprises a fixed end on the side wall and a free end extending from the fixed end, the shell axially rotates around the shell under the operation of the operation catheter, the hook body is stretched out or drawn back in the radial direction of the shell in different rotating directions, the free end of the hook body pierces into and hooks up and holds myocardium in the stretched-out state, and therefore the intracardiac implant is fixed to the myocardium. The myocardium is fixed in a shell rotating mode, the fixing mode is easy and convenient to operate and stable and reliable, and therefore the safety and practicability of the intracardiac implant can be improved.

Description

technical field [0001] The invention relates to the field of implantable medical devices, and more specifically, to an implant in a cardiac cavity and a fixing method thereof. 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 body. Today, millions of people around the world ar...
