Embodiment Construction

[0036] In order to make the purpose, advantages and features of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0037] As used herein, the terms "proximal" and "distal"; and "caudal" and "leading" refer to the relative orientation, relative position, relative position, relative position, direction, although "proximal" and "distal" are not limiting, but "proximal" and "tail" generally refer to the end of the medical device that is close to the physician during normal operation, while "distal", " "Tip end" generally refers to the end that first enters the patient.

[0038] As used in this specification and the appended claims, the singular forms "a," "an," and "the" inc...

Abstract

The invention provides an electrode lead wire. In the case of an abnormal sinoatrial node, pace making of a pacemaker on the sinoatrial node can be achieved. The electrode lead wire comprises a main electrode body and a fixing mechanism, and the main electrode body is arranged on the fixing mechanism; the fixing mechanism comprises an outer tube and an expandable and contractible bracket; the outer tube is provided with a hollow passage which is through axially; the bracket is arranged on the outer tube and abuts against the side wall of an implanted object; the main electrode body is partially accommodated in the hollow passage, and the distal end of the main electrode body extends out of the outer tube to sense the predetermined object and / or conduct pace making on the predetermined object.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an electrode lead. Background technique [0002] Since its introduction in 1958, cardiac pacemakers have become the first-line treatment for bradyarrhythmia diseases. [0003] The basic structure of a cardiac pacing system generally includes a pacemaker and electrode leads. The pacemaker includes a pulse generator, and the pacemaker uses the pulse generator to send out a pulse current, and the pulse current stimulates the diseased organ through the electrode wire implanted in the heart, blood vessels and other human tissues, so as to treat some dysfunction of the diseased organ . [0004] The existing electrode leads are mainly fixed in the ventricle or atrium to realize single-chamber or double-chamber pacing. However, the pacing of a normal heart starts from the sinoatrial node of the atrium, and the automatically generated excitement is transmitted to various pa...
