A leadless pacemaker () and trailing () and leading () components thereof are disclosed. The trailing component () includes a first connecting member () and a second connecting member (), and the leading component () includes a third connecting member () and a fourth connecting member (). The first connecting member () is configured to be detachably connected to the third connecting member () and the second connecting member () is configured to be detachably or non-detachably connected to the fourth connecting member (), thereby achieving interlocking between the trailing component () and the leading component (). Additionally, both the first connecting member () and the third connecting member () are non-biodegradable. At least one of the second connecting member () and the fourth connecting member () is biodegradable, or the second connecting member () is fitted and connected to the fourth connecting member () by an associated biodegradable connecting member. Thus, before the connecting member is degraded, it can be ensured that the trailing component () and the leading component () are firmly connected together by the four connecting members, facilitating overall retrieval or adjustment of the pacemaker (). Moreover, after the connecting member is degraded, the trailing component () can be easily retrieved.

Leadless pacemaker and tail end component and head end component thereof

A medical device for treating cardiac rhythm disorders, and a cardiac implantation device and a pacing system. The cardiac implantation device includes: a first connecting member having an end configured to be coupled to a pacemaker; and N support struts, each of the N support struts having a proximal end coupled to the other end of the first connecting member. The support struts are provided thereon with anchor(s) configured to secure during implantation. Distal ends of the support struts are free and are able to radiate outwardly or converge inwardly. The pacing system includes the implantation device and a pacemaker. A leadless pacemaker can be implanted into the superior vena cava in order to achieve atrial sensing and pacing. Moreover, the leadless pacemaker can be more easily retrieved after long-term implantation at a high success rate, promoting the application of leadless pacemakers and enhancing patients' use experience.

Cardiac implantation device and pacing system

A pacemaker fixation system, a leadless pacemaker system and a method of use thereof are disclosed. The leadless pacemaker system includes: a pacemaker fixation system including a leadless pacemaker and an elastic unfoldable element attached thereto, wherein in an unfolded configuration of the elastic unfoldable element, it fixes the leadless pacemaker at a target location in a blood vessel in communication with the heart; a delivery system for delivering the pacemaker fixation system to the target location; and a guide for guiding the delivery system into the blood vessel. According to the present invention, atrial pacing can be achieved by the leadless pacemaker through fixing the leadless pacemaker in the blood vessel in communication with the heart with the elastic unfoldable element.

Pace-making fixing system, lead-free pacemaker system, and use method therefor

An active cardiac electrical lead is disclosed, including a tip housing having a lumen, a soft tip plug and a marker band. The tip housing includes a body and an extension extending from a distal end of the body, and the body is of greater outer diameter than the extension. The soft tip plug fits over the extension and engaging the extension. The marker band is attached to an outer surface of the body or to an inner surface of the lumen.
