Embodiment 1

[0034] Such as Figure 1-11 As shown, a pacing electrode wire includes a connecting wire 1, an implanted end 2 and a connecting end 3; the implanted end 2 is used for connecting with the patient's myocardial tissue, and the connecting end is used for connecting with a cardiac pacemaker. The wire is used to connect the implant end and the connection end; specifically, the connection wire 1 includes an inner connection layer 11, an inner insulation layer 12, an outer connection layer 13 and an outer insulation layer 14, and the inner connection layer and the outer connection layer are made of conductive materials. The specific material type is not limited, as long as it meets the medical standard; both the inner connection layer and the outer connection layer are formed by synchronously coiling multiple metal wires, which are opened in a spiral structure and have elasticity; in this embodiment, The outer connection layer 13 is formed by bending and winding 4 metal wires (the 4 m...

Embodiment 2

[0045] Such as Figure 12-13 As shown, the difference between this embodiment and Embodiment 1 is that a hormone part 41 is installed on the end of the anode part 23, and the hormone part 41 is a hormone releasing ring, containing dexamethasone sodium phosphate hormone, so that when the hormone part After being in contact with the myocardium, it can release the dexamethasone sodium phosphate hormone, which has an anti-inflammatory effect, prevents the threshold from rising in the acute phase, and reduces impedance, and the hormone part 41 is made of insulating material, so that the anode part does not directly contact the myocardium. The contact prevents the capture of the anode part 23, so that the current output from the implant head 21 will not directly enter the anode part, ensuring the smooth progress of cardiac pacing.

[0046] In other embodiments, dexamethasone sodium phosphate hormone can also be directly applied on the anode part 23 .

[0047]Further, in this embodi...

Abstract

The invention discloses a pace-making electrode wire. The pace-making electrode wire comprises a connecting wire, an implantation end arranged at one end of the connecting wire and a connecting end arranged at the other end of the connecting wire. The implantation end comprises a shell, an implantation head, an implantation driving structure and a hormone part, the implantation head can rotate back and forth and extend-retract relative to the shell, and at least part of the implantation head can be implanted into a left bundle branch area; the implantation driving structure is used for drivingthe implantation head to rotate back and forth and extend-retract; and the hormone part is used for releasing hormone to myocardium. According to the pace-making electrode wire, through the arrangement of the implantation head and the implantation driving structure, pace-making of the left bundle branch area can be achieved, the pace-making part is closer to the physiological pace-making part, and the pace-making effect is better.

Description

technical field [0001] The invention belongs to the technical field of artificial cardiac pacemakers, in particular to a pacing electrode lead. Background technique [0002] Cardiac pacemaker is an electronic therapy device implanted in the body. It sends out electric pulses powered by batteries through the pulse generator, and through the conduction of the wire electrodes, it stimulates the myocardium in contact with the electrodes, so that the myocardium is excited and contracted, so as to achieve therapeutic effect. For the purpose of cardiac dysfunction due to certain arrhythmias and heart failure. [0003] However, the existing conventional electrode wire needs to rotate the whole electrode wire, which is inconvenient to rotate and fix, and the operation is difficult. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the present invention provides a pacing electrode wire with convenient fixing and simple operation. [0005] I...
