Problems solved by technology

Therefore, the existing leadless pacemakers cannot be fixed in some narrow spaces, such as the vessel wall or interventricular septum, and these narrow spaces may be the best pacing positions
[0006] Therefore, the existing leadless pacemaker cannot be implanted in some optimal pacing positions with relatively narrow spaces, resulting in poor pacing effect

Embodiment Construction

[0053] In order to make the purpose and features of the present invention more obvious and understandable, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in different forms and should not be limited to the described embodiments. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. In addition, it needs to be further explained that the "head end" of a certain part mentioned in the present invention refers to the end that first enters the body when the part is implanted in the body. Correspondingly, the "tail end" of a certain part It refers to the end that enters the body last or the end that is exposed outside the body when the component is implanted in the body. The "axial directio...

Abstract

The invention provides a lead-free pacemaker and a lead-free pacemaker system. The lead-free pacemaker and the lead-free pacemaker system have the advantages that a shell of a pacemaker body of the lead-free pacemaker is designed to be of a bent pipe structure, accordingly, the lead-free pacemaker can be implanted in locations with narrow spaces in a bent manner and can effectively cling to myocardial tissues or vascular wall tissues which are of curved surface structures, good pace-making or perception effects can be realized, the patient application ranges can be expanded to a great extent,and large quantities of patients can be benefited.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a leadless pacemaker and a leadless pacemaker system. Background technique [0002] Since its introduction in 1958, cardiac pacemakers have become the first-line treatment for bradyarrhythmia diseases. After more than half a century of development and innovation, the pacemaker has been implanted with a single wire through the chest to pace the ventricle, and gradually developed into 2 to 3 wires implanted through the vein to provide atrioventricular physiological pacing and even biventricular synchronization. pacing. Lead-related complications such as lead dislocation, thrombosis, tricuspid regurgitation, and infection not only affect the normal work of the pacemaker, but also seriously endanger the life, health and quality of life of patients. Lead removal is difficult and risky and needs to be done by skilled physicians in larger electrophysiology centers. How to ove...
