[0035] The following disclosure provides several different implementations or examples for carrying out this application. To simplify the disclosure of this application, specific examples of components and methods are described below. Of course, these are merely examples and are not intended to limit this application. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0036] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a pacemaker device according to an embodiment of this application. Figure 2This is a schematic diagram of a pacing device with a removal adjustment structure and positioning guide according to an embodiment of this application. The pacing device provided in this embodiment is used to stimulate the heart 10 of a user. The pacing device includes a body 200, a pulse generator, an atrial electrode, and a ventricular electrode 300. The body 200 is disposed in the interatrial septum 11 of the user's heart 10. The pulse generator is disposed inside the body 200. The atrial electrode is disposed in the body 200 and contacts the atrium of the user's heart 10. The ventricular electrode 300 is disposed in the ventricle 12 of the user. The pulse generator is configured to be electrically connected to the atrial electrode and the ventricular electrode 300 and to send the pulse signals it generates 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 signals.
[0037] The pacing device provided in the embodiments of this application is directly installed in the interatrial septum 11 of the user's heart 10, which can reduce damage to the user's body during surgery. Furthermore, since the pulse generator is installed inside the main body 200, it can improve the problems that occur when the pulse generator is installed outside the heart, and there is no need to use an external power source to power the pacing device.
[0038] See Figure 3 , Figure 3 This is a schematic diagram of the structure of a body 200 according to an embodiment of the present application. In this embodiment, the body 200 may include a first part 210 and a second part 220. The first part 210 and the second part 220 are delivered to the user's heart 10 by an input device, and the first part 210 and the second part 220 are fixedly disposed in the interatrial septum 11. A pulse generator is disposed between the first part 210 and the second part 220.
[0039] The first part 210 and the second part 220 can be a retractable mesh structure. The first part 210 and the second part 220 are connected, and the first part 210 and the second part are located on both sides of the atrial septum. When the mesh structure is unfolded, it is fixed to the atrial septum. The atrial electrodes, pulse generator, and power supply are mounted on the mesh structure, so that the atrial electrodes, pulse generator, and power supply are also fixed to the atrial septum.
[0040] In some embodiments, the atrial electrode may be disposed on the outer side of the first part 210 so that it contacts the atrium of the heart 10.
[0041] In some embodiments, the pacing device further includes a ventricular electrode retraction device 400 and an adjustment structure 500. The ventricular electrode retraction device 400 is disposed in the first part 210, and the adjustment structure 500 is configured to cooperate with the ventricular electrode retraction device 400 to adjust the position of the ventricular electrode 300 when the ventricular electrode 300 is installed in the heart 10.
[0042] The ventricular electrode deployment and retraction device 400 may include, for example, a rotating shaft, with a portion of the ventricular electrode 300 wound around the ventricular electrode deployment and retraction device 400. The adjustment structure 500 is configured to drive the ventricular electrode deployment and retraction device 400 to rotate, thereby changing the length of the ventricular electrode 300 on the ventricular electrode deployment and retraction device 400 and thus adjusting the position of the ventricular electrode 300.
[0043] In some embodiments, the adjustment structure 500 is configured to access the user's atrium from the user's inferior vena cava 13, and the ventricular electrode retraction device 400 is adjusted to adjust the position of the ventricular electrode 300 in the ventricle 12.
[0044] In some embodiments, the ventricular electrode 300 is configured to extend from the body 200 toward the user's ventricle 12 and to have its end fixed to the user's interventricular septum 14.
[0045] See Figure 2 One end of the ventricular electrode 300 can be fixed to the user's interventricular septum 14. After the ventricular electrode 300 is fixed to the interventricular septum 14 using the adjustment structure 500 in conjunction with the ventricular electrode retraction device 400, the adjustment structure 500 can be removed from the user's inferior vena cava 13.
[0046] In some embodiments, the pacing device further includes a positioning guide 600 configured to position and guide the end portion 310 of the ventricular electrode 300 when the ventricular electrode 300 is secured to the user's interventricular septum 14.
[0047] By setting the positioning guide 600, the end 310 of the ventricular electrode can be positioned more accurately to the predetermined position and then fixed to the user's interventricular septum 14.
[0048] In some embodiments, the end portion 310 of the ventricular electrode is configured to be magnetic, and the positioning guide 600 is configured to be magnetic, so that the positioning guide 600 positions the end portion 310 of the ventricular electrode by the magnetic force between the two.
[0049] It is easy to understand that it is difficult to accurately position the ventricular electrode 300 by directly operating it. Positioning and guiding the ventricular electrode 300 by the positioning guide 600 makes the positioning more accurate. When it reaches the appropriate position, the ventricular electrode is accurately positioned to the predetermined position by the action of magnetic force.
[0050] 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. The positioning guide 600 is configured to extend along one side of the interventricular septum 14 and to guide and position the ventricular electrode 300 on the other side of the interventricular septum 14 using magnetic force.
[0051] like Figure 2 As shown, after the positioning guide 600 positions and fixes the ventricular electrode 300 to the interventricular septum 14, the positioning guide 600 is removed through the aorta 15.
[0052] In some embodiments, the end 310 of the ventricular electrode is provided with a barbed structure, and the positioning guide 600 magnetically attracts the barbed structure 310 to guide it to be fixed to a predetermined position in the interventricular septum 14.
[0053] When using the positioning guide 600 to guide and position the barbed structure 310, the positioning guide 600 can first guide the ventricular electrode 300 to move at a position far from the interventricular septum 14. After the barbed structure 310 moves to the predetermined position, the positioning guide 600 is brought close to the interventricular septum 14 to increase the magnetic force on the barbed structure 310, thereby causing the barbed structure 310 to pierce the interventricular septum 14 and fix it to the predetermined position of the interventricular septum 14.
[0054] According to another embodiment of this application, a pacing device for stimulating a user's heartbeat includes: a body disposed in the interatrial septum of the user's heart, the body including a pulse generator, a power supply, and an atrial electrode; and a ventricular electrode disposed in the ventricle of the user's heart, connected to the pulse generator and in contact with the atrium of the user's heart; the pulse generator is configured to be electrically connected to the atrial and ventricular electrodes and to send pulse signals generated therefrom to the atrial and ventricular electrodes, the atrial and ventricular electrodes stimulating the heartbeat according to the pulse signals.
[0055] In this embodiment, the pulse generator, power supply, and atrial electrodes are made into a stretchable mesh structure, and are made into a first part and a second part. The first part and the second part are delivered to the user's heart using an input device, and the first part and the second part are fixedly installed in the interatrial septum.
[0056] Specifically, the mesh structure, which includes a pulse generator, power supply, and atrial electrodes, first contracts together. After being input into a predetermined location in the user's heart using an input device, a portion of it begins to expand, followed by another portion. Furthermore, both the expanded portion and the second expanded portion are then fixed in the predetermined location. This predetermined location could be, for example, the atrial septum.
[0057] 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 here.
[0058] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.
[0059] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
