Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a shock wave balloon catheter device. Background Art

[0002] As heart disease patients age and the disease progresses, plaques in peripheral blood vessels and coronary arteries gradually calcify. This bone-like structure analogue causes vascular stenosis, reduces vascular blood flow, and may eventually lead to complete vascular occlusion. A shock wave balloon catheter device is provided for vascular calcification lesions; during treatment, the balloon on the catheter is pushed into the vascular calcification area; the balloon is then inflated and pressurized with liquid to make it contact with the inner wall of the blood vessel; a high-voltage pulse is applied to the electrode pair in the balloon, causing the electrode pair to discharge and generate shock waves in the liquid, which are then transmitted to the inner wall of the blood vessel to rupture the calcified plaque.

[0003] In some cases, in the circumferential direction of the blood vessel, only some arc segments may have calcified lesions, which are the treatment areas that require shock wave therapy; the remaining arc segments have no calcified or slightly calcified lesions and are non-treatment areas. However, in existing shock wave balloon catheter devices, the shock waves are basically uniformly propagated radially to the inner wall of the contacting blood vessels, applying shock wave energy to the treatment area and the non-treatment area. The shock wave energy applied to the non-treatment area may cause damage to the inner wall of the blood vessel in the non-treatment area.

[0004] For example, the blood vessel between the left ventricle and the aorta has an aortic valve, which is composed of three leaflets. The accumulation of calcium deposits on the leaflets will cause the leaflets to harden significantly and impair their ability to open and close effectively, leading to aortic valve stenosis and obstructing blood flow. The shock wave balloon catheter device can be used to break up the calcium deposits on the leaflets. However, in some cases, there may be only one or two leaflets with calcium deposits, which are therapeutic leaflets that require shock wave therapy; leaflets with no calcification deposits or slight calcification deposits are non-therapeutic leaflets that do not require shock wave therapy; and existing shock wave balloon catheter devices can only apply shock waves to the three leaflets basically evenly, and shock waves applied to leaflets with no calcification deposits or slight calcification deposits may also cause damage to them. Summary of the invention

[0005] The embodiments of the present application provide a shock wave balloon catheter device, which can apply shock waves to a treatment area where calcified lesions exist in the circumferential direction of a blood vessel; and at the same time, can reduce the shock wave energy applied to a non-treatment area in the circumferential direction of the blood vessel.

[0006] In one embodiment of the present application, a shock wave balloon catheter device is provided, comprising:

[0007] a first balloon and a second balloon; in a treatment state, the first balloon and the second balloon are configured to be distributed along the circumference of the blood vessel; one of the first balloon and the second balloon is configured to be filled with liquid, and the other balloon is configured to be filled with gas;

[0008] A first electrode assembly is disposed in the first balloon; when the first balloon is filled with liquid and a voltage is applied to the first electrode assembly, the first electrode assembly can generate a discharge arc in the liquid in the first balloon;

[0009] A second electrode assembly is disposed in the second balloon; when the second balloon is filled with liquid and a voltage is applied to the second electrode assembly, the second electrode assembly can generate a discharge arc in the liquid in the second balloon.

[0010] In another embodiment of the present application, a shock wave balloon catheter device is provided, comprising:

[0011] a first balloon; the first balloon is filled with liquid, and a first electrode assembly is disposed in the first balloon; when a voltage is applied to the first electrode assembly, the first electrode assembly can generate a discharge arc in the liquid of the first balloon;

[0012] a second balloon; the second balloon is filled with gas; in a treatment state, the first balloon and the second balloon are configured to be distributed circumferentially along the blood vessel.

[0013] In the embodiments provided by the present application, in the treatment state, the first balloon and the second balloon are configured to be distributed along the circumference of the blood vessel; one of the first balloon and the second balloon is configured to be filled with liquid and contact the treatment area, and the other balloon is configured to be filled with gas and contact the non-treatment area; voltage is applied to the electrode assembly in the liquid-filled balloon and shock waves are generated, so that shock wave energy can be applied to the treatment area; and because the conduction capacity of gas for mechanical shock waves is lower than that of liquid, the balloon filled with gas can attenuate the shock wave energy, thereby reducing the shock wave energy applied to the non-treatment area.

[0018] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope. After reading the present invention, modifications of various equivalent forms of the present invention by those skilled in the art all fall within the scope defined by the present application.

[0019] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an element in the middle. 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 element in the middle. The "proximal end" in this application refers to the side close to the operator, and the "distal end" refers to the side away from the operator.

[0020] The following will be combined Figures 1 to 3 The shock wave balloon catheter device of the embodiment of this specification is explained and described. It should be noted that in the embodiment of the present invention, the same reference numerals represent the same components. For the sake of brevity, the detailed description of the same components is omitted in different embodiments, and the descriptions of the same components can be referenced and quoted to each other.

[0021] As heart disease patients age and the disease progresses, plaques in peripheral blood vessels and coronary arteries gradually calcify. This bone-like structure can cause narrowing of the vessels, reduce blood flow in the vessels, and may eventually lead to complete occlusion of the vessels.

[0022] The indications of the shock wave balloon catheter device include interventional treatment of vascular calcification lesions. The shock wave balloon catheter device includes a catheter, a balloon sealed around the outer circumference of the catheter, and at least one electrode pair arranged in the balloon; the balloon can be filled with liquid; each of the electrode pairs includes a first electrode and a second electrode; when a voltage is applied between the first electrode and the second electrode, a plasma arc is formed in the liquid in the balloon between the first electrode and the second electrode, thereby generating bubbles in the liquid, which expand and collapse, and then forming a mechanical shock wave in the balloon, which is mechanically transmitted through the liquid and the balloon to apply mechanical force or pressure to split any calcified plaque on or in the wall of the vascular system.

[0023] When the device is in clinical use, the balloon on the catheter is pushed into the vascular calcification area, and the balloon is pressurized to ensure close contact with the blood vessel wall; then a voltage is applied between the first electrode and the second electrode, and a shock wave is formed in the liquid in the balloon between the first electrode and the second electrode. The shock wave impacts and destroys the calcified lesions of the blood vessel, causing the calcification of the intima and the media to break. The modification effect of the calcified lesions can be judged by evaluating the symmetrical expansion of the balloon.

[0024] The shock wave balloon catheter device efficiently and safely destroys superficial and deep calcifications, thereby significantly improving vascular compliance. The device is effective not only for superficial and deep calcifications, but also for eccentric and non-eccentric lesions, reducing the risk of complications such as dissection and perforation.

[0025] In some cases, in the circumferential direction of the blood vessel, only some arc segments may have calcified lesions, which are the treatment areas that require shock wave therapy; the remaining arc segments have no calcified or slightly calcified lesions and are non-treatment areas. However, in existing shock wave balloon catheter devices, the shock waves are basically uniformly propagated radially to the inner wall of the contacting blood vessels, applying shock wave energy to the treatment area and the non-treatment area. The shock wave energy applied to the non-treatment area may cause damage to the inner wall of the blood vessel in the non-treatment area.

[0026] The blood vessel between the left ventricle and the aorta has the aortic valve, such as Figure 3 As shown, the aortic valve inhibits the blood flow injected into the aorta from flowing back into the left ventricle. The aortic valve is composed of three leaflets 5. The accumulation of calcium deposits 501 on the leaflets 5 will cause aortic valve stenosis and hinder blood flow. The shock wave balloon catheter device can be used to break up the calcium deposits 501 on the leaflets 5; and compared with the calcified plaques in other vascular parts, the calcified tissue of the aortic valve requires greater shock wave energy to complete the treatment. However, there may be only one or two leaflets 5 with calcium deposits 501, which are the treatment leaflets that require shock wave treatment; for leaflets 5 with no calcification deposits or slight calcification deposits, they are non-treatment leaflets that do not require shock wave treatment; and the existing shock wave balloon catheter device can only apply shock waves to the three leaflets 5 basically evenly, and the shock waves applied to the leaflets 5 with no calcification deposits or slight calcification deposits may also cause damage to them.

[0027] To solve the above problems, an embodiment of the present application provides a shock wave balloon catheter device, comprising:

[0028] a first balloon and a second balloon; in a treatment state, the first balloon and the second balloon are configured to be distributed along the circumference of the blood vessel; one of the first balloon and the second balloon is configured to be filled with liquid, and the other balloon is configured to be filled with gas;

[0029] A first electrode assembly is disposed in the first balloon; when the first balloon is filled with liquid and a voltage is applied to the first electrode assembly, the first electrode assembly can generate a discharge arc in the liquid in the first balloon;

[0030] A second electrode assembly is disposed in the second balloon; when the second balloon is filled with liquid and a voltage is applied to the second electrode assembly, the second electrode assembly can generate a discharge arc in the liquid in the second balloon.

[0031] In the treatment state, the first balloon and the second balloon are configured to be distributed along the circumference of the blood vessel; one of the first balloon and the second balloon is configured to be filled with liquid and contact the treatment area, and the other balloon is configured to be filled with gas and contact the non-treatment area; applying voltage to the electrode assembly in the liquid-filled balloon and generating shock waves can apply shock wave energy to the treatment area; and because the conduction capacity of gas for mechanical shock waves is lower than that of liquid, the gas-filled balloon can attenuate the shock wave energy, thereby reducing the shock wave energy applied to the non-treatment area.

[0032] The balloons in the above embodiment can be two or more and can be used for shock wave treatment of calcified lesions in coronary vessels, peripheral blood vessels and aortic valves.

[0033] Optionally, the device of this embodiment further includes

[0034] a first catheter; the first balloon is sealed around the outer circumference of the first catheter; the first catheter is provided with a first fluid channel connected to the first balloon;

[0035] a second catheter; the second balloon is sealed around the outer circumference of the second catheter; and a second fluid channel connected to the second balloon is provided on the second catheter;

[0036] The first fluid channel and the second fluid channel are isolated from each other, so that the corresponding balloon can be filled with liquid or gas, or the liquid or gas filled in the corresponding balloon can be replaced as needed.

[0037] Optionally, the device of this embodiment further includes:

[0038] A first power supply circuit; the first power supply circuit is used to provide voltage to the first electrode assembly;

[0039] A second power supply circuit; the second power supply circuit is used to provide voltage to the second electrode assembly;

[0040] The first power supply circuit and the second power supply circuit are connected to a pulse voltage generator and are configured to be independently controllable so that voltage can be applied to the electrode assembly in the balloon filled with liquid as needed, while no voltage can be applied to the electrode assembly in the balloon filled with gas.

[0041] Optionally, during treatment, the first balloon contacts the treatment area and is configured to be filled with liquid; the second balloon contacts the non-treatment area, and the second balloon and the third balloon are both configured to be filled with gas. Applying voltage to the first electrode assembly in the first balloon and generating shock waves can apply shock wave energy to the treatment leaflet; and because the conduction capacity of gas for mechanical shock waves is lower than that of liquid for mechanical shock waves, the second balloon can attenuate the shock wave energy, thereby reducing the shock wave energy applied to the non-treatment area.

[0042] After the treatment of the treatment area corresponding to the first balloon is completed, if the non-treatment area needs to be treated again, there are two options:

[0043] The first solution is to replace the liquid in the first balloon with gas, and replace the gas in the second balloon with liquid, and then apply voltage to the second electrode assembly in the second balloon to generate shock waves;

[0044] The second solution is to rotate and move the position of the first balloon so that it contacts the treatment area; then apply voltage to the first electrode assembly in the first balloon to generate shock waves.

[0045] In another optional embodiment, another shock wave balloon catheter device is provided, such as Figure 1 As shown, including:

[0046] A first balloon 101, a second balloon 201 and a third balloon 301; in a treatment state, the first balloon 101, the second balloon 201 and the third balloon 301 are configured to be distributed along the circumference of the blood vessel; among the first balloon 101, the second balloon 201 and the third balloon 301, at least one balloon is configured to be filled with liquid, and at least one balloon is configured to be filled with gas;

[0047] A first electrode assembly 102 is disposed in the first balloon 101; when the first balloon 101 is filled with liquid and a voltage is applied to the first electrode assembly 102, the first electrode assembly 102 can generate a discharge arc in the liquid of the first balloon 101;

[0048] A second electrode assembly 202 is disposed in the second balloon 201; when the second balloon 201 is filled with liquid and a voltage is applied to the second electrode assembly 202, the second electrode assembly 202 can generate a discharge arc in the liquid of the second balloon 201;

[0049] A third electrode assembly 302 is disposed in the third balloon 301 ; when the third balloon 301 is filled with liquid and a voltage is applied to the third electrode assembly 302 , the third electrode assembly 302 can generate a discharge arc in the liquid in the third balloon 301 .

[0050] This embodiment can be used for shock wave treatment of calcified lesions of coronary vessels, peripheral blood vessels and aortic valves, but is particularly suitable for shock wave treatment of calcified lesions of aortic valves.

[0051] When the shock wave balloon catheter device of this embodiment is used to treat calcified lesions of the aortic valve, the outer wall of the first balloon 101, the outer wall of the second balloon 201, and the outer wall of the third balloon 301 are connected to the three leaflets of the aortic valve in a one-to-one correspondence;

[0052] Among the first balloon 101 , the second balloon 201 , and the third balloon 301 , the balloon contacting the treatment leaflet is configured to be filled with liquid, and the balloon contacting the non-treatment leaflet is configured to be filled with gas.

[0053] Optionally, the device of this embodiment further includes

[0054] A first catheter 103; the first balloon 101 is sealed around the outer circumference of the first catheter 103; the first catheter 103 is provided with a first fluid channel connected to the first balloon 101;

[0055] The second catheter 203; the second balloon 201 is sealed around the outer circumference of the second catheter 203; the second catheter 203 is provided with a second fluid channel connected to the second balloon 201;

[0056] A third catheter 303; the third balloon 301 is sealed around the outer periphery of the third catheter 303; the third catheter 303 is provided with a third fluid channel connected to the third balloon 301;

[0057] The first fluid channel, the second fluid channel and the third fluid channel are isolated from each other, so that liquid or gas can be filled into the corresponding balloon as needed, or the liquid or gas filled in the corresponding balloon can be replaced.

[0058] Optionally, the device of this embodiment further includes:

[0059] A first power supply circuit; the first power supply circuit is used to provide voltage to the first electrode assembly 102;

[0060] A second power supply circuit; the second power supply circuit is used to provide voltage to the second electrode assembly 202;

[0061] A third power supply circuit; the third power supply circuit is used to provide voltage to the third electrode assembly 302;

[0062] The first power supply circuit, the second power supply circuit and the third power supply circuit are connected to the pulse voltage generator 4 and are configured to be independently controllable, so that voltage can be applied to the electrode assembly in the balloon filled with liquid as needed, and no voltage can be applied to the electrode assembly in the balloon filled with gas.

[0063] Optional, when treating, e.g. Figure 2 As shown, calcium deposits 501 are accumulated on one of the leaflets, which serves as a treatment leaflet. The first balloon 101 contacts one treatment leaflet, and the first balloon 101 is configured to be filled with liquid; the second balloon 201 and the third balloon 301 contact the other two non-treatment leaflets respectively, and the second balloon 201 and the third balloon 301 are configured to be filled with gas. Applying voltage to the first electrode assembly 102 in the first balloon 101 and generating shock waves can apply shock wave energy to the treatment leaflet; and because the conduction capacity of gas for mechanical shock waves is lower than that of liquid for mechanical shock waves, the second balloon 201 and the third balloon 301 can attenuate the shock wave energy, thereby reducing the shock wave energy applied to the other two non-treatment leaflets.

[0064] After the treatment of the treated leaflet corresponding to the first balloon 101 is completed, if it is necessary to treat at least one of the other two non-treated leaflets, there are two options:

[0065] Solution 1 is to replace the liquid in the first balloon 101 with gas, and replace the gas in the balloon corresponding to the next valve leaflet to be treated with liquid, and then apply voltage to the electrode assembly in the balloon filled with liquid to generate shock waves;

[0066] Solution 2 is to rotate and move the position of the first balloon 101 so that it contacts the next valve leaflet to be treated; then apply voltage to the first electrode assembly 102 in the first balloon 101 to generate shock waves.

[0067] It is known that, according to need, liquid can be simultaneously filled into two balloons, and voltage can be applied to the corresponding electrode assemblies respectively, so that only one balloon is filled with gas.

[0068] Another embodiment of the present application provides yet another shock wave balloon catheter device, comprising:

[0069] a first balloon; the first balloon is filled with liquid, and a first electrode assembly is disposed in the first balloon; when a voltage is applied to the first electrode assembly, the first electrode assembly can generate a discharge arc in the liquid of the first balloon;

[0070] The second balloon is filled with gas; in the interventional treatment state, the first balloon and the second balloon are configured to be distributed along the circumference of the blood vessel.

[0071] In the treatment state, the first balloon and the second balloon are configured to be distributed along the circumference of the blood vessel; the first balloon is configured to be filled with liquid and contact the treatment area, and the second balloon is configured to be filled with gas and contact the non-treatment area; applying voltage to the first electrode assembly in the first balloon and generating shock waves can apply shock wave energy to the treatment area; and since the conduction capacity of gas for mechanical shock waves is lower than that of liquid, the second balloon can attenuate the shock wave energy, thereby reducing the shock wave energy applied to the non-treatment area.

[0072] In this embodiment, the electrode assembly may not be disposed in the second balloon, so the second balloon is not used to generate shock waves, but is specifically used to attenuate shock wave energy.

[0073] Another embodiment of the present application provides yet another shock wave balloon catheter device, comprising:

[0074] a first balloon; the first balloon is filled with liquid, and a first electrode assembly is disposed in the first balloon; when a voltage is applied to the first electrode assembly, the first electrode assembly can generate a discharge arc in the liquid of the first balloon;

[0075] A second balloon; the second balloon is filled with gas;

[0076] a third balloon; the third balloon is filled with liquid, and a third electrode assembly is arranged in the third balloon; when a voltage is applied to the third electrode assembly, the third electrode assembly can generate a discharge arc in the liquid of the third balloon;

[0077] In the treatment state, the first balloon, the second balloon and the third balloon are configured to be distributed along the circumference of the blood vessel; the first balloon and the third balloon are configured to be filled with liquid and contact the treatment area, and the second balloon is configured to be filled with gas and contact the non-treatment area; voltage is applied to the first electrode assembly in the first balloon and the third electrode assembly in the third balloon to generate shock waves, so that shock wave energy can be applied to the treatment area; and because the conduction capacity of gas for mechanical shock waves is lower than that of liquid, the second balloon can attenuate the shock wave energy, thereby reducing the shock wave energy applied to the non-treatment area.

[0078] In this embodiment, the electrode assembly may not be disposed in the second balloon, so the second balloon is not used to generate shock waves, but is specifically used to attenuate shock wave energy.

[0079] Another embodiment of the present application provides yet another shock wave balloon catheter device, comprising:

[0080] a first balloon; the first balloon is filled with liquid, and a first electrode assembly is disposed in the first balloon; when a voltage is applied to the first electrode assembly, the first electrode assembly can generate a discharge arc in the liquid of the first balloon;

[0081] A second balloon; the second balloon is filled with gas;

[0082] A third balloon; the third balloon is filled with gas;

[0083] In the treatment state, the first balloon, the second balloon and the third balloon are configured to be distributed along the circumference of the blood vessel; the first balloon is configured to be filled with liquid and contact the treatment area, and the second balloon and the third balloon are configured to be filled with gas and contact the non-treatment area; applying voltage to the first electrode assembly in the first balloon and generating shock waves can apply shock wave energy to the treatment area; and because the conduction capacity of gas for mechanical shock waves is lower than that of liquid, the second balloon and the third balloon can attenuate the shock wave energy, thereby reducing the shock wave energy applied to the non-treatment area.

[0084] In this embodiment, the electrode assembly may not be provided in the second balloon and the third balloon, so the second balloon and the third balloon are not used to generate shock waves, but are specifically used to attenuate shock wave energy.

[0085] Optionally, the gas filled in the balloon in the above embodiment is nitrous oxide. When the balloon filled with gas ruptures accidentally in a blood vessel, the nitrous oxide can quickly combine with red blood cells after entering the blood, so it is not easy to cause air embolism.
