Anti-dislocation left ventricle electrode wire

Abstract

The embodiment of the invention discloses an anti-dislocation left ventricle electrode wire which comprises a spindly catheter, wherein the catheter comprises a near end and a remote end; the near end is configured as a connector connected with a heart pacemaker; an end pacing electrode is arranged at the tip of the remote end; the remote end is bent twice to form a first oblique angle and a second oblique angle in sequence; lateral fixing wings are arranged on the side, approaching the near end, of the second oblique angle, and comprise folded elastomers which protrude in the normal direction of the catheter; when the folds of the elastomers extend or contract in the axial direction of the catheter, the lateral fixing wings contract or extend correspondingly in the normal direction of the catheter. The anti-dislocation left ventricle electrode wire provided by the embodiment of the invention adopts the design of double oblique angles, so that the position fixed effect of the anti-dislocation left ventricle electrode wire in a target vein can be greatly enhanced; moreover, the lateral fixing wings are arranged on the side, approaching the near end, of the second oblique angle, and the folds of the lateral fixing wings extend and are supported on the wall of a target vessel during use, so that the position fixed effect of the anti-dislocation left ventricle electrode wire can be further enhanced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dislocation-preventing left ventricle electrode lead. Background technique [0002] Cardiac resynchronization therapy (CRT) is the treatment of heart failure patients with asynchronous ventricular systole through ventricular pacing, which is a revolution in the field of heart failure treatment. During cardiac resynchronization therapy, a pacemaker provides therapeutic stimulation to the heart by delivering pacing, cardioversion, or defibrillation pulses through implantable leads. The pulses are delivered to the heart via electrodes disposed on the lead, such as typically near the distal end of the lead. In this case, the lead leads allow the electrodes to be positioned in various locations relative to the heart to enable the pacemaker to deliver pulses to the appropriate locations. If the electrodes are dislocated during the treatment process due to poor fixation of t...
