[0017] The following disclosure provides a plurality of different embodiments or examples for implementing the present application. In order to simplify the disclosure of the present application, the components and methods of specific examples are described below. Of course, they are merely examples and the purpose is not to limit the present application. In the description of embodiments of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly specified.

[0018] Referring to FIG. 1 and FIG. 2, FIG. 1 is a structural schematic diagram of a pacing device according to an embodiment of the present application, and FIG. 2 is a structural schematic diagram of the pacing device with a retrieval adjustment structure and a positioning guide according to an embodiment of the present application. The pacing device provided by the embodiment is used to stimulate the heart 10 of a user to beat, and the pacing device comprises a body 200, a pulse generator, an atrial electrode and a ventricular electrode 300. The body 200 is arranged at the atrial septum 11 of the heart 10 of the user, the pulse generator is arranged in the body 200, the atrial electrode is arranged in the body 200 and contacts the atrium of the heart 10 of the user, and the ventricular electrode 300 is arranged in the ventricle 12 of the user. The pulse generator is arranged to be electrically connected with the atrial electrode and the ventricular electrode 300, and sends the pulse signal generated thereby to the atrial electrode and the ventricular electrode 300. The atrial electrode and the ventricular electrode 300 stimulate the heart 10 to beat according to the pulse signal.

[0019] The pacing device provided by the embodiment of the present application is directly arranged at the atrial septum 11 of the heart 10 of the user, which can reduce the damage to the body of the user during the operation. In addition, since the pulse generator is arranged in the body 200, the problems of arranging the pulse generator outside the heart can be improved, and the pacing device does not need to be powered by an external power source.

[0020] Referring to FIG. 3, FIG. 3 is a structural schematic diagram of the body 200 according to an embodiment of the present application. In the embodiment, the body 200 can comprise a first part 210 and a second part 220. The first part 210 and the second part 220 are delivered to the heart 10 of the user by using an input device, and are fixedly arranged at the atrial septum 11. The pulse generator is arranged between the first part 210 and the second part 220.

[0021] The first part 210 and the second part 220 can be a mesh structure capable of being stretched and contracted. The first part 210 and the second part 220 are connected, and the first part 210 and the second part are respectively located on two sides of the atrial septum. When the mesh structure is expanded, it is fixed to the atrial septum. The atrial electrode, the pulse generator and the power source are arranged on the mesh structure, so that the atrial electrode, the pulse generator and the power source are also fixed to the atrial septum.

[0022] In some embodiments, the atrial electrode can be arranged on the outside of the first part 210, so as to contact the atrium of the heart 10.

[0023] In some embodiments, the pacing device further comprises a ventricular electrode retraction device 400 and an adjustment structure 500. The ventricular electrode retraction device 400 is arranged in the first part 210, and the adjustment structure 500 is arranged to cooperate with the ventricular electrode retraction device 400 when the ventricular electrode 300 is installed in the heart 10, so as to adjust the position of the ventricular electrode 300.

[0024] The ventricular electrode retraction device 400 may, for example, include a spool around which a portion of the ventricular electrode 300 is wound, and the adjustment structure 500 is configured to rotate the spool to change the length of the ventricular electrode 300 wound around the spool, thereby adjusting the position of the ventricular electrode 300.

[0025] In some embodiments, the adjustment structure 500 is configured to enter the user's atrium from the user's inferior vena cava 13 and adjust the ventricular electrode retraction device 400 to adjust the position of the ventricular electrode 300 in the user's ventricle 12.

[0026] In some embodiments, the ventricular electrode 300 is configured to extend from the body 200 to the user's ventricle 12 and to secure its end to the user's interventricular septum 14.

[0027] Referring to FIG. 2, one end of the ventricular electrode 300 can be secured to the user's interventricular septum 14, and the adjustment structure 500 can be removed from the user's inferior vena cava 13 after the ventricular electrode 300 is secured to the interventricular septum 14 using the adjustment structure 500 in cooperation with the ventricular electrode retraction device 400.

[0028] In some embodiments, the pacing device further includes a positioning guide 600 configured to position and guide the end 310 of the ventricular electrode 300 when the ventricular electrode 300 is secured to the user's interventricular septum 14.

[0029] By providing the positioning guide 600, the end 310 of the ventricular electrode 300 can be more accurately positioned to a predetermined position and secured to the user's interventricular septum 14.

[0030] In some embodiments, the end 310 of the ventricular electrode 300 is configured to be magnetic, and the positioning guide 600 is configured to be magnetic, such that the positioning guide 600 positions the end 310 of the ventricular electrode 300 by magnetic force between the two.

[0031] As can be readily appreciated, it is more difficult to accurately position the ventricular electrode 300 by directly manipulating the ventricular electrode 300, and the positioning guide 600 provides more accurate positioning of the ventricular electrode 300 by positioning and guiding the ventricular electrode 300, and accurately positioning the ventricular electrode to a predetermined position by magnetic force when it reaches the appropriate position.

[0032] In some embodiments, the positioning guide 600 enters the user's left ventricle 121 through the user's aorta 15, and the ventricular electrode 300 is located in the user's right ventricle 122, and the positioning guide 600 is configured to extend along one side of the interventricular septum 14 and guide and position the ventricular electrode 300 on the other side of the interventricular septum 14 using magnetic force.

[0033] As shown in Fig. 2, after the positioning guide 600 positions and fixes the ventricular electrode 300 to the interventricular septum 14, the positioning guide 600 is taken out through the aorta 15.

[0034] In some embodiments, the end portion 310 of the ventricular electrode is provided in a barb structure, and the positioning guide 600 magnetically attracts the barb structure 310 to guide it to be fixed to the predetermined position of the interventricular septum 14.

[0035] When the positioning guide 600 is used to guide and position the barb structure 310, the positioning guide 600 can first guide the ventricular electrode 300 to move at a position far from the interventricular septum 14, and when the barb structure 310 moves to the predetermined position, the positioning guide 600 is close to the interventricular septum 14 to increase the magnetic force on the barb structure 310, so that the barb structure 310 penetrates into the interventricular septum 14 to be fixed to the predetermined position of the interventricular septum 14.

[0036] According to another embodiment of the present application, a pacing device for stimulating a user's heart to beat comprises: a body arranged at an atrial septum of the user's heart, the body comprising a pulse generator, a power supply and an atrial electrode; a ventricular electrode arranged in contact with the atrial electrode and arranged in contact with an atrium of the user's heart, the ventricular electrode arranged in a ventricle of the user's heart; the pulse generator arranged in electrical connection with the atrial electrode and the ventricular electrode and arranged to transmit a pulse signal generated thereby to the atrial electrode and the ventricular electrode, the atrial electrode and the ventricular electrode arranged to stimulate the heart to beat in response to the pulse signal.

[0037] In this embodiment, the pulse generator, the power supply and the atrial electrode are formed in a telescopic mesh structure, and are formed in a first portion and a second portion, the first portion and the second portion being arranged to be delivered to the user's heart using an input device and arranged to be fixed at the atrial septum.

[0038] In particular, the mesh structure having the functions of the pulse generator, the power supply and the atrial electrode is first contracted together, and after being delivered to a predetermined position in the user's heart using the input device, a first portion of the mesh structure is caused to expand, and then a second portion of the mesh structure is caused to expand, and further, the expanded first portion and the expanded second portion are fixed at the predetermined position. The predetermined position can be, for example, the atrial septum.

[0039] The other structures of the pacing device in this embodiment are the same as those in the previous embodiment, and will not be described in detail.

[0040] It should be noted that the embodiments of the present application can be combined with each other to obtain new embodiments without conflict.

[0041] The above merely describes specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and the protection scope of the present application should be subject to the protection scope of the claims.
