Abstract
Description
Conductive components, electrodes, stimulators and medical systems CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to the Chinese patent application filed on December 19, 2023, with application number 202311750934.2 and titled “Conductive components, electrodes, stimulators and medical systems”. Technical Field
[0002] The present invention relates to the technical field of electrical stimulation therapy, and in particular to a conductive component, an electrode, a stimulator and a medical system. Background Art
[0003] With the development of modern medicine, electrical stimulation therapy technology has become an important treatment method. It uses pulsed currents of different frequencies to stimulate nerve or muscle tissue to treat pain, promote recovery or improve the symptoms of certain diseases (such as Parkinson's disease and epilepsy).
[0004] When applying electrical stimulation therapy, a stimulator is typically used to apply electrical stimulation. The stimulator consists of a pulse generator and electrodes. The pulse generator generates electrical stimulation pulses that are transmitted to the electrodes. The electrodes are implanted in the body and apply electrical stimulation to the target area, thereby exerting a therapeutic effect.
[0005] In actual use, the electrodes will be affected by external forces, and there is a risk of short circuit. Summary of the Invention
[0006] Based on this, it is necessary to provide a conductive component and an electrode to address the above problems.
[0007] In order to solve the above problems, the present invention provides the following technical solutions:
[0008] A conductive component includes: an inner support member; a plurality of guide wires, at least one of which is fitted on the inner support member, and an insulating separator is provided between adjacent guide wires; and a first sleeve, which is sleeved on the outside of the inner support member and clamps the guide wire together with the inner support member.
[0009] The conductive component has at least the following beneficial effects:
[0010] On the one hand, because the guide wire is clamped by the inner support and the first sleeve, the guide wire will not undergo a large displacement relative to the contact object when subjected to external force. This can prevent the guide wires from coming into close contact with each other, which is beneficial to avoiding the risk of short circuit. It can also reduce the degree of friction between the guide wire and the contact object when subjected to external force, thereby protecting the guide wire and improving the stability and reliability of the electrode.
[0011] On the other hand, adjacent guidewires are separated by insulating separators. Even if a guidewire is subjected to external forces and rubs, squeezes, or collides with the separators, it cannot contact other guidewires, thus eliminating the risk of contact short circuits between the guidewires. Furthermore, the guidewires are clamped together by the inner support member and the first sleeve. When subjected to external forces, the guidewires will not undergo significant displacement relative to the objects they are in contact with. This prevents the guidewires from crossing the separators and contacting other guidewires when subjected to external forces, thus avoiding the risk of contact short circuits between the guidewires.
[0012] In addition, the inner support and the first sleeve jointly clamp the guide wire, which is also beneficial to prevent the guide wire from deviating from its original position and being pulled when subjected to external force, thereby preventing the guide wire from being torn off, and preventing the connection between the guide wire and the stimulation contacts and connection contacts from being loosened or torn off, which is beneficial to improving the stability and reliability of the electrode.
[0013] In one embodiment, the first sleeve and the inner support member jointly clamp the partition.
[0014] With this arrangement, the separator contacts both the first sleeve and the inner support member, and the spaces where adjacent guide wires are located are isolated by the inner support member therebetween, which ensures that adjacent guide wires are separated by the separator.
[0015] In one embodiment, the separator is arranged to fit the adjacent guide wire.
[0016] With this arrangement, the guide wire is in contact with the first sleeve, the inner support and the two adjacent partitions, and the position of the guide wire is completely restricted by the first sleeve, the inner support and the two adjacent partitions, which helps prevent the guide wire from undergoing a large displacement relative to the contacting object when subjected to external force, thereby reducing the degree of friction between the guide wire and the contacting object when subjected to external force.
[0017] In one embodiment, the partition is fixed to the inner support member.
[0018] With this arrangement, the separator is fixed to the inner support member, and relative movement between the separator and the inner support member does not occur, thereby preventing the guide wire and the separator from making slight displacement relative to the inner support member and the first sleeve.
[0019] In one embodiment, the guide wire is at least partially helically wound around the inner support.
[0020] This arrangement provides the guide wire with a certain amount of deformation margin, allowing it to stretch, bend, and flex, thus allowing the electrode to stretch, bend, and flex. Even if the guide wire is stretched, bent, or flexed by external forces, the deformation margin prevents the guide wire from being torn, and the connection between the guide wire and the stimulation contacts and the connection contacts from being loosened or torn off, thereby improving the stability and reliability of the electrode.
[0021] In one embodiment, the guide wire includes a conductive core for conducting electricity and an insulating layer covering the outside of the conductive core.
[0022] Such an arrangement can further prevent short circuits between the guide wires.
[0023] In one embodiment, the first sleeve and / or the inner support member and / or the separator are made of TPU or silicone.
[0024] Such an arrangement is helpful in preventing rejection reactions of biological tissues.
[0025] In one embodiment, the conductive component further includes a second sleeve, and the second sleeve is snugly sleeved on the first sleeve.
[0026] With this arrangement, during assembly, the first sleeve is first sleeved on the outside of the inner support to jointly clamp the guide wire and the separator, and then the assembled guide wire and separator are inserted into the second sleeve. In this way, during the final assembly process, the guide wire and the separator are subjected to less friction and their positions will not change significantly, which can improve assembly efficiency.
[0027] In one embodiment, the inner support member is a hollow tubular structure.
[0028] This arrangement makes the hollow tubular inner support more easily stretchable, bendable, and flexible, facilitating electrode implantation in a living organism and helping the electrode adapt to the movements of the implant site. Furthermore, both the first sleeve and the inner support are implemented as hollow tubular structures. This ensures that the inner side of the guidewire is always supported by the inner support and the outer side of the guidewire is always pressed by the first sleeve, facilitating the first sleeve and the inner support to stably hold the guidewire. It also makes the conductive assembly more compact, thereby reducing its volume.
[0029] The present invention also provides an electrode, which includes the above-mentioned conductive component.
[0030] Because the electrode includes the above-mentioned conductive component, the electrode has the technical effect of the above-mentioned conductive component.
[0031] The present invention also provides a stimulator, which includes the above-mentioned electrode.
[0032] Because the stimulator includes the above-mentioned electrodes, the stimulator has the technical effects of the above-mentioned electrodes.
[0033] The present invention also provides a medical system, which includes the stimulator mentioned above.
[0034] Because the medical system includes the above-mentioned stimulator, the medical system has the technical effects of the above-mentioned stimulator. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0049] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0050] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0051] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0052] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.
[0053] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.
[0054] Referring to Figures 1 to 4, one embodiment of the present invention provides a conductive component 1, which is used to connect the stimulation contact 2 and the connection contact 3 on the electrode. It may include an inner support 11, a guide wire 12 and a first sleeve 14. There are multiple guide wires 12, at least one of which is fitted on the inner support 11. The first sleeve 14 is sleeved on the outside of the inner support 11 and clamps the guide wire 12 together with the inner support 11. Because the guide wire 12 is clamped by the inner support 11 and the first sleeve 14, the guide wire 12 will not be displaced significantly relative to the contact object when subjected to external force. This can prevent the guide wires 12 from coming into close contact with each other, which is beneficial to avoiding the risk of short circuits. It can also reduce the degree of friction between the guide wire 12 and the contact object when subjected to external force, thereby protecting the guide wire 12 and improving the stability and reliability of the electrode.
[0055] It should be noted that the aforementioned displacement refers to relative displacement, and the direction of displacement includes both the radial direction and the axial direction of the first cannula 14. In other words, because the guide wire 12 is clamped by both the inner support member 11 and the first cannula 14, when an external force is applied to the guide wire 12, it will not undergo significant displacement relative to the contacting object in either the radial or axial direction of the first cannula 14.
[0056] The inner support member 11 and the first sleeve 14 are constructed of an elastic material to allow the conductive component 1 to stretch, bend, and flex, thereby facilitating electrode implantation in a living organism and enabling the electrode to adapt to the movements of the implant site. It should be noted that the aforementioned living organisms include, but are not limited to, humans, other primates, and seals; and the movements of the implant site include, but are not limited to, muscle contraction and expansion.
[0057] It is worth mentioning that the inner support member 11 and the first sleeve 14 jointly clamp the guide wire 12, which is also beneficial to prevent the guide wire 12 from deviating from its original position and being pulled when subjected to external force, thereby preventing the guide wire 12 from being torn off, and preventing the connection between the guide wire 12 and the stimulation contact 2 and the connection contact 3 from being loosened or torn off, which is beneficial to improving the stability and reliability of the electrode.
[0058] In some embodiments, portions of some guidewires 12 are in contact with the inner support 11 and the first sleeve 14, so as to be clamped by the inner support 11 and the first sleeve 14. Some portions of these guidewires 12 are allowed to detach from the inner support 11 and / or the first sleeve 14. The clamping of portions of these guidewires 12 can also limit the large displacement of the guidewires 12 and reduce the degree of friction between the guidewires 12 and contacting objects.
[0059] Preferably, in order to limit the guide wire 12 from large displacement and reduce the degree of friction between the guide wire 12 and the contacting object as much as possible, each guide wire 12 is arranged in a close fit on the inner support member 11.
[0060] Referring to Figures 1, 2, and 4, the conductive component 1 can further include an insulating separator 13, and a separator 13 is provided between every two adjacent guide wires 12. In this way, adjacent guide wires 12 are separated by the insulating separator 13. Even if the guide wire 12 is subjected to an external force, the guide wire 12 cannot cross the separator 13 and contact the adjacent guide wire, so there is no risk of contact short circuit between the guide wires 12. Moreover, the guide wire 12 is clamped together by the inner support member 11 and the first sleeve 14. When the guide wire 12 is subjected to an external force, it will not undergo a large displacement relative to the object it contacts. This further prevents the guide wire 12 from crossing the separator 13 and contacting other guide wires 12 when subjected to an external force, which is conducive to avoiding the risk of contact short circuit between the guide wires 12.
[0061] Preferably, referring to Figures 1, 2, and 4, the first sleeve 14 and the inner support 11 jointly clamp the separator 13. In this way, the separator 13 contacts both the first sleeve 14 and the inner support 11, and the spaces between adjacent guide wires 12 are isolated by the inner support 11 therebetween, which ensures that adjacent guide wires 12 are separated by the separator 13.
[0062] It is understood that in another embodiment of the present invention, the separator 13 may also be connected to the inner support member 11 and spaced apart from the first sleeve 14. As long as the spacing between the separator 13 and the first sleeve 14 is small enough, adjacent guide wires 12 can still be separated by the separator 13. Of course, in other embodiments of the present invention, the separator 13 may also be connected to the first sleeve 14 and spaced apart from the inner support member 11, which will not be described in detail in the present invention.
[0063] Preferably, referring to Figures 2 and 4 , the separator 13 is disposed in close contact with the adjacent guide wires 12. Thus, the guide wire 12 is in contact with the first sleeve 14, the inner support 11, and the two adjacent separators 13. The position of the guide wire 12 is completely restricted by the first sleeve 14, the inner support 11, and the two adjacent separators 13, which helps prevent the guide wire 12 from significantly displacing relative to the contacting object when subjected to an external force, thereby reducing the degree of friction between the guide wire 12 and the contacting object when subjected to an external force.
[0064] More preferably, the separator 13 conforms to the adjacent guidewire 12. For example, if the guidewire 12 is a thin cylinder, the contact portion of the separator 13 with the guidewire 12 is arc-shaped. Thus, when the separator 13 and the adjacent guidewire 12 are attached together, the two adjacent separators 13 cover most of the guidewire 12 between them, which helps to fully restrict the position of the guidewire 12 and prevent the guidewire 12 from significantly displacing relative to the contacting object when subjected to external forces.
[0065] Optionally, the separator 13 is bonded to the inner support 11. In this way, the separator 13 is fixed to the inner support 11, and relative movement between the separator 13 and the inner support 11 is prevented, thereby preventing the guide wires 12 and the separator 13 from undergoing slight displacement relative to the inner support 11 and the first sleeve 14. Specifically, during the manufacturing process of the conductive component 1, the guide wires 12 can be first mounted on the inner support 11, and then the gaps between adjacent guide wires 12 can be filled with silicone. After drying, the silicone forms the separator 13 and adheres to the inner support 11.
[0066] It is understood that in other embodiments of the present invention, the separator 13 may also be bonded to the first sleeve 14, or integrally formed with the inner support 11, or integrally formed with the first sleeve 14, so as to be fixedly disposed on one of the inner support 11 and the first sleeve 14. For example, the separator 13 and the inner support 11 may be integrally formed by injection molding using TPU (Thermoplastic Polyurethane) or silicone.
[0067] Preferably, referring to Figures 1, 2, and 4, the guide wire 12 is spirally wound around the inner support 11, which allows the guide wire 12 to have a certain deformation margin, so that the guide wire 12 can stretch, bend, and fold to allow the electrode to stretch, bend, and fold. On the one hand, this facilitates the implantation of the electrode into the organism and helps the electrode adapt to the activities of the implantation site. On the other hand, even if the guide wire 12 is stretched, bent, or folded due to the action of an external force, due to the presence of the deformation margin, the guide wire 12 will not be torn off, and the connection between the guide wire 12 and the stimulation contact 2 and the connection contact 3 will not be loosened or pulled off, which is conducive to improving the stability and reliability of the electrode. Referring to Figures 1, 2, and 4, in this embodiment, because the separator 13 is provided between adjacent guide wires 12, and the adjacent guide wires 12 are spirally wound around the inner support 11, the separator 13 is also spirally wound around the inner support 11.
[0068] It is worth mentioning that compared with the spiral structure formed by spirally winding adjacent guide wires together in the traditional technology, in the embodiments shown in Figures 1, 2, and 4, due to the provision of the separator 13, the lead of the spiral structure formed by the spiral winding of the guide wire 12 is increased, which can reduce the number of turns of the spiral structure formed by the guide wire 12, reduce the length of the guide wire 12, save the amount of the guide wire 12, and reduce the production cost of the electrode.
[0069] It is understandable that the guide wire 12 can be completely spirally wound around the inner support 11, or it can be partially spirally wound around the inner support 11. For example, the two ends of the guide wire 12 are straight or curved, and the middle part of the guide wire 12 is spiral. In another embodiment of the present invention, the guide wire 12 as a whole can also be arc-shaped, so that the guide wire 12 is in a relaxed state, thereby allowing the guide wire 12 to bend, bend and allow the size of the guide wire 12 along the axis of the first sleeve 14 to change, so as to allow the electrode to bend, bend and stretch, thereby facilitating the implantation of the electrode into the organism, helping the electrode to adapt to the activities of the implantation site and preventing the guide wire 12 from being torn off, preventing the connection between the guide wire 12 and the stimulation contact 2 and the connection contact 3 from being loosened or pulled off. Of course, in other embodiments of the present invention, the guide wire 12 as a whole can also be in other curved shapes, as long as the guide wire 12 is in a relaxed state.
[0070] It is noteworthy that, according to the above-mentioned embodiment of the present invention, because the insulating separator 13 has separated the adjacent guide wires 12, an insulating layer may not be provided on the guide wire 12. In one embodiment of the present invention, in order to further prevent different guide wires 12 from contacting and short-circuiting, the guide wire 12 is implemented to include a conductive core for conducting electricity and an insulating layer coated on the outside of the conductive core. As previously mentioned, because the guide wire 12 is clamped together by the inner support 11 and the first sleeve 14, the guide wire 12 will not undergo a large displacement relative to the object in contact when subjected to an external force, which can reduce the degree to which the insulating layer of the guide wire 12 rubs against the object in contact when subjected to an external force, thereby reducing the risk of the conductive core being partially exposed due to damage to the insulating layer due to rubbing, avoiding the risk of short-circuiting between exposed guide wires 12, and improving the stability and reliability of the electrode.
[0071] Optionally, the conductive core is made of a material with good biocompatibility. Exemplarily, the conductive core is made of platinum or a platinum-iridium alloy.
[0072] Optionally, the insulating layer is made of a material with good biocompatibility. Preferably, the insulating layer is made of polytetrafluoroethylene or polyimide, which have good wear resistance and are conducive to preventing the insulating layer from being damaged by scratches during long-term use.
[0073] Preferably, the first sleeve 14 is made of TPU or silicone with good biocompatibility, so that the first sleeve 14 will not cause a rejection reaction of the biological tissue after contacting the biological tissue. The first sleeve 14 can serve as the outermost layer of the conductive component 1 to separate its internal structure from the biological tissue.
[0074] Preferably, the inner support member 11 and the separator 13 are also made of TPU or silicone, so that even if the inner support member 11 and the separator 13 accidentally contact the implantation site, the inner support member 11 and the separator 13 will not cause a rejection reaction of the biological tissue.
[0075] More preferably, the inner support member 11 is made of TPU and the first sleeve 14 is made of silicone. Compared to silicone, TPU has better wear resistance, strength and hardness. The inner support member 11 made of TPU has certain wear resistance, strength and hardness, and will not be easily worn, which is conducive to extending the service life of the conductive component 1. Compared to TPU, silicone has better biocompatibility. The first sleeve 14 made of silicone can better prevent the rejection reaction of biological tissue; silicone is also softer. The first sleeve 14 made of silicone can better adapt to the activities of the implant site and is not easy to damage biological tissue. Therefore, the first sleeve 14 made of silicone is suitable as the outermost layer of the conductive component 1, used to separate its internal structure from biological tissue.
[0076] Preferably, referring to Figures 1, 2, and 4, the conductive assembly 1 may further include a second sleeve 15, which is snugly sleeved on the first sleeve 14. During assembly, the first sleeve 14 is first sleeved on the outside of the inner support member 11 to jointly clamp the guide wire 12 and the separator 13, and then the assembled guide wire 12 and separator 13 are inserted into the second sleeve 15. In this way, during the final assembly process, the guide wire 12 and the separator 13 are subjected to less friction and their positions will not change significantly, which can improve assembly efficiency.
[0077] More preferably, the inner support member 11 and the first sleeve 14 are made of TPU, and the second sleeve 15 is made of silicone. This ensures that both the inner support member 11 and the first sleeve 14 possess a certain degree of wear resistance, strength, and hardness, preventing them from easily wearing out. This facilitates their long-term and stable joint clamping of the guidewire 12 and the separator 13. The second sleeve 15, made of silicone, can better prevent rejection reactions from biological tissue, better adapt to the movement of the implant site, and is less likely to damage biological tissue. It is therefore suitable as the outermost layer of the conductive component 1, isolating its internal structures from biological tissue.
[0078] Referring to Figures 1, 2, and 4, since the first sleeve 14 is a hollow tubular structure, the first sleeve 14 can cover the inner support member 11 and the guide wire 12 inside it, thereby sealing the inner support member 11 and the guide wire 12 to isolate the inner support member 11 and the guide wire 12 from the outside world, thereby protecting the inner support member 11 and the guide wire 12.
[0079] Preferably, referring to Figures 1, 2, and 4, the inner support member 11 is also implemented as a hollow tubular structure. Compared to a solid structure, the hollow tubular inner support member 11 is easier to stretch, bend, and fold, making it easier to implant the electrode into the body and helping the electrode adapt to the movement of the implanted site.
[0080] It is worth mentioning that the first sleeve 14 and the inner support member 11 are both implemented as hollow tubular structures. On the one hand, this can ensure that the inner side of the guide wire 12 is always supported by the inner support member 11, and that the outer side of the guide wire 12 is always pressed by the first sleeve 14, which is conducive to the first sleeve 14 and the inner support member 11 to jointly and stably clamp the guide wire 12; on the other hand, this also makes the structure of the conductive component 1 compact, which is conducive to reducing the volume of the conductive component 1.
[0081] Optionally, in an embodiment where the inner support member 11 is made of silicone, since silicone is relatively soft and easily stretched, bent and folded, the inner support member 11 may also be implemented as a solid structure. The structure of the inner support member 11 is not limited herein.
[0082] Preferably, referring to FIG2 , the number of guide wires 12 is 4, and the separators 13 are of the same shape and number as the guide wires 12, and are spirally or partially spirally wound side by side around the inner support member 11. Of course, in other embodiments, the number of guide wires 12 may also be 2, 3, or 8, etc., which is not limited here.
[0083] Referring to Figures 5 and 6 , one embodiment of the present invention further provides an electrode 100 comprising a stimulation contact 2, a connection contact 3, and the aforementioned conductive component 1. The ends of a guidewire 12 are connected to the stimulation contact 2 and the connection contact 3, respectively. Because electrode 100 includes the aforementioned conductive component 1, it exhibits the technical effects of the aforementioned conductive component 1. Since the relevant technical effects have been fully described above, they will not be repeated here.
[0084] Referring to Figures 5 and 6, the stimulation contact 2 and the connection contact 3 are both annular, and the conductive component 1 is in the shape of a thin cylinder. The stimulation contact 2 and the connection contact 3 are both sleeved on the outermost layer of the conductive component 1 and are both tightly pressed against the circumferential surface of the outermost layer of the conductive component 1. The two ends of the guide wire 12 pass through the outermost layer of the conductive component 1 to electrically connect the stimulation contact 2 and the connection contact 3, respectively. Specifically, the two ends of the guide wire 12 can be made to contact the stimulation contact 2 and the connection contact 3, respectively, and UV glue (ultraviolet light curing glue) can be applied to the connection between the guide wire 12, the stimulation contact 2, and the connection contact 3. The UV glue is irradiated with ultraviolet light to fully solidify the UV glue, thereby fixing the two ends of the guide wire 12 to the stimulation contact 2 and the connection contact 3, respectively.
[0085] Referring to Figures 5 and 6, the stimulation contacts 2, the connection contacts 3, and the guide wire 12 are each provided with a plurality, and the stimulation contacts 2, the connection contacts 3, and the guide wire 12 are arranged in a one-to-one correspondence. In other words, the two ends of each guide wire 12 are respectively connected to a stimulation contact 2 and a connection contact 3. In this way, different stimulation contacts 2 can be made to contact different target sites, which can meet the need for applying electrical stimulation to multiple target sites at the same time. The multiple connection contacts 3 in this embodiment can be respectively connected to different channels on the pulse generator 200. By controlling the power-on state of different channels, the stimulation contacts 2 that need to exert electrical stimulation can be energized as needed, while the stimulation contacts 2 that do not need to exert electrical stimulation can be de-energized.
[0086] Referring to FIG6 , one embodiment of the present invention further provides a stimulator, comprising a pulse generator 200 and the aforementioned electrode 100. The electrode 100 is electrically connected to the pulse generator 200 via a connection contact 3. The electrical stimulation pulses generated by the pulse generator 200 are sequentially transmitted through the connection contact 3 and the guidewire 12 to the stimulation contact 2. The stimulation contact 2 is implanted in a living body and applies electrical stimulation to a target area, thereby exerting a therapeutic effect.
