Abstract

The invention discloses a cardiac-pacing wire with a fixing device. The cardiac-pacing wire comprises a conduction fixing device and a limiting containing device. The conduction fixing device comprises two or more memory metal conductor arms expanding in the radial direction of the wire. Pacing electrode parts and insulating parts are arranged on the conductor arms. The limiting containing device controls the conduction fixing device to be in the expanded and unfolded state or the stored and folded state.

Description

technical field [0001] The patent of the present invention relates to a cardiac pacing lead, in particular to a cardiac pacing lead with a fixing device. Background technique [0002] At present, cardiac resynchronization therapy is one of the effective methods for the clinical treatment of heart failure. The pacing electrodes are placed in the left and right ventricles and the right atrium, respectively, and the pulse generator is connected to make the gap between the atrioventricular and the left and right ventricle With synchronous excitation, the heart returns to synchronous contraction, thereby correcting heart failure. Among them, the synchronous contraction of the left ventricle is very important, and the placement of the left ventricle electrode is also the most difficult part of resynchronization therapy. Usually, by inserting electrodes into the coronary vein through the right atrium, reaching the branches of the coronary vein, and connecting the pulse generator t...
