Problems solved by technology

The disadvantages of this system and technology are: 1) It is necessary to repeatedly screw in and out the wire to find the left bundle branch during the operation, which is time-consuming and increases the risk of infection during the operation; 2) the right bundle branch is damaged during the process of screwing in the wire; 3) During the operation, the right bundle coronary septal branch was damaged during the wire insertion process; 4) The tip of the wire is very close to the left ventricle of the ventricular septum, and there may be perforation of the ventricular septum after the operation, which directly affects the pacing parameters and requires reoperation

Abstract

The invention discloses a leadless pacing system for achieving left bundle branch pacing on the left ventricle side of an interventricular space, and relates to the field of surgical instruments. Thesystem includes: a pulse generator; and a delivery system for delivering the pulse generator to cause the pulse generator to screw into the myocardium and contact the left branch.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a leadless pacing system for realizing left bundle branch pacing at the left ventricle side of the interventricular septum. Background technique [0002] At present, the lead wire used to achieve left bundle branch pacing is the lead wire of a traditional cardiac pacemaker. After puncturing the left or right subclavian vein, the lead wire is implanted along the vein to the right ventricle. The leading end of the lead is a helical structure, which can be screwed into the interventricular septum and reach the left bundle branch or the myocardium in the left bundle branch region, and the tail end is connected to the pulse generator. The disadvantages of this system and technology are: 1) It is necessary to repeatedly screw in and out the wire to find the left bundle branch during the operation, which is time-consuming and increases the risk of infection during the operation; 2) t...
