Problems solved by technology

This problem limits the further development and promotion of this new technology
The existing fixing devices for wireless miniature pacemakers either use active screw-like devices to screw into the myocardium, which can easily cause heart perforation, cardiac tamponade, and life-threatening; or they can be fixed by hooking the reticular myocardial structure in the ventricle On the one hand, it is easy to fall off, causing embolism; on the other hand, the electrode is not in good contact with the myocardium, which affects the perception of ECG and pacing effects, and there is a lack of mesh tissue in the atrium. Using existing fixing devices, it is impossible to achieve atrial pacing and double-chamber heart Pacing, the effect, physiology and safety of pacing are difficult to be guaranteed

Embodiment Construction

[0033] 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.

[0034] In the following embodiments, the implant fixation device is described by taking a miniature pacemaker as an example.

[0035] Figure 1a and 1b The three-dimensional schematic diagrams of the heart implant according to the first embodiment of the present invention when it is in the sleeve and in the free state are respectively shown.

[0036] In this embodiment, the cardiac implant is a miniature pacemaker 100 . The miniature pacemaker 100 includes a casing 110 , a first electrode 111 and a second electrode 112 . The first electrode 111 and the second electrode 112 are, for example, metal conductors exposed on the sidewall of the casing 110 , and are insulat...

Abstract

The invention discloses a heart implant and a fixation method thereof. The heart implant comprises a housing comprising a side wall and an end portion; a first electrode and a second electrode which are arranged on the housing and are mutually electrically insulated; and a memory alloy gripper which is arranged on the housing, comprises a fixed end used for fixation on the housing and a free end used for clamping an atrial septum or grapping trabecular muscles / papillary muscles and is in a first shape at a conduit transmission state and in a second shape at a fixed state. The heart implant employs the memory alloy gripper as a fixation apparatus, such that the stability, the safety and the practicality of the heart implant can be improved.

Description

technical field [0001] The invention relates to the field of medical equipment, more specifically, to a heart implant and a fixing method thereof, mainly aiming at the fixing of atrial wireless miniature pacemakers. Background technique [0002] Placing heart implants in the heart chamber is the latest diagnosis and treatment method in modern medicine. Cardiac implants in the heart chamber, including sensors for obtaining parameters such as ECG, blood pressure, blood flow, and blood biochemistry, as well as miniature therapeutic devices for performing sustained drug release, cardiac pacing, and other treatments. In order to place a cardiac implant into the heart cavity, transcatheter intervention is required to deliver the implant to a specific location in the heart cavity and fix it to prevent the heart implant from dislodging or falling off, causing the implant to Complications such as failure or embolism. [0003] Pacemakers are widely used implants in the human body. ...
