Description

经皮介入的射频消融电极导管 Percutaneous radiofrequency catheter ablation electrode

技术领域 FIELD

[0001] 本发明属于医疗器械领域,具体涉及一种通过去肾交感神经来治疗高血压的经皮介入的射频消融电极导管。 [0001] The present invention belongs to the field of medical devices, particularly to relates to a process for treating hypertension in renal sympathetic Percutaneous radiofrequency ablation catheter electrode.

背景技术 Background technique

[0002] 高血压是严重影响人们生存质量和危及生命的常见疾病,也是全球导致死亡的主要病因,每年全世界七百万人因高血压死亡。 [0002] Hypertension is a serious impact on people's quality of life and life-threatening diseases common, is the world's major cause of death worldwide every year seven million people died due to high blood pressure. 2004年10月12日国务院新闻办新闻发布会上发布的“中国居民营养与健康状况调查报告”中指出:我国成人高血压患病率为18.8%,而人群高血压知晓率、治疗率和控制率仅为30.2%,24.7%和6.1%。 October 12, 2004 issued by the State Council Information Office press conference, "Nutrition and health survey of Chinese residents," pointed out: My adult prevalence of hypertension was 18.8%, while the population of hypertension awareness, treatment and control rate was 30.2%, 24.7% and 6.1%. 即使在美国,高血压近年的治疗的控制率也不足30%。 Even in the US, the treatment of hypertension control rate in recent years was less than 30%. 目前,我国是世界上高血压危害最严重的国家之一,估计全国高血压患者已超过2亿。 At present, China is one of the most serious hypertension in the world, estimated that the country has more than 200 million patients with hypertension.

[0003] 国内外流行的高血压治疗是药物治疗。 [0003] popular at home and abroad is the treatment of hypertension drug treatment. 其治疗的目的是通过药物作用于导致血压升高的各个环节,干扰引起体内血压升高的诸多要素而控制血压;治疗所用的药物其中最受关注且起主要作用的是钙通道阻滞剂、血管紧张素转化酶抑制剂和血管紧张素II受体拮抗剂,而且尤以后两类药物为主要,而这后两类药物的作用都在肾素-血管紧张素系统。 Its purpose is achieved by drug treatment in all aspects of increased blood pressure, many elements causing disturbance within the control of blood pressure and blood pressure; drugs used in the treatment of most concern and which play a major role is a calcium channel blocker, angiotensin converting enzyme inhibitors and angiotensin II receptor antagonists, and particularly the latter two as the main drugs, which are the effect of two drugs in the renin - angiotensin system. 该类药物的长期联合用药治疗,将不仅需要长期服用而且价格不菲、副作用突出,最主要的是因其个体差异、副作用较多、控制率不佳,导致其治疗效果依然不理想。 Long-term combination therapy of these drugs, will require not only expensive but long-term use, side effects prominent, most notably because of individual differences, more side effects, poor control rates, leading to its therapeutic effect is still not ideal. 特别是顽固性高血压在临床上较常见,致病因素众多,发病机制不明确,药物治疗效果很差。 Especially resistant hypertension is more common in clinical practice, a number of risk factors, pathogenesis is not clear, poor drug treatment.

[0004] 医学界一直认为,肾脏的交感神经兴奋和血压升高关系密切。 [0004] the medical profession has been that the kidney sympathetic nervous excitement and high blood pressure are closely related. 肾脏的交感神经过度兴奋时,肾脏血管收缩,减少肾脏的排泌,使水分和盐滞留在体内,同时促进肾脏分泌肾素,导致了血液中血管紧张素II和醛固酮的增加,而后两种物质,正是血压升高的因素。 When kidney sympathetic overactivity, renal vasoconstriction, reduce renal excretion, moisture and salt retention in the body, while promoting renal renin secretion, resulting in an increase in blood angiotensin II and aldosterone, the latter two substances , it is high blood pressure factor. 早期的研究是采用切除支配肾交感神经节的方法,该方法虽能达到降压的目的,但是损伤大,并发症多。 Early research method is the use of disposable resection of renal sympathetic ganglia, although this method can achieve step-down, but the damage, complications. 2009年3月,在美国奥兰多举行的美国心脏学院(ACC)第58届科学大会上,澳大利亚Monash大学的Krum教授提出了一种全新的治疗顽固性高血压的非药物方法一一射频消融去除支配肾脏的交感神经,即通过股动脉穿刺和血管造影,将特制的射频消融导管导入肾动脉,发出射频能量破坏支配肾脏的交感神经来治疗高血压,从而显著降低顽固性高血压病人的血压。 March 2009, held in Orlando American College of Cardiology (ACC) 58th Annual Scientific Conference, Professor Krum Monash University in Australia proposed a new treatment resistant hypertension eleven non-drug methods to remove disposable radiofrequency ablation kidney sympathetic, i.e., through the femoral artery and angiographic puncture, the special radiofrequency ablation catheter into the renal arteries, radiate radio frequency energy to destroy the kidney sympathetic innervation treating hypertension, thus significantly reducing blood pressure in hypertensive patients with refractory. 这种降压治疗新方法的理论基础是:肾脏的交感神经传入和传出纤维分布在肾动脉壁下方的浅表部位,其活性与高血压的发生和维持密切相关,在肾动脉局部进行射频消融能损毁肾脏交感神经而不累及其他腹部、盆腔或下肢的神经组织。 This theoretical basis of antihypertensive therapy is a new approach: incoming and outgoing renal sympathetic fiber distribution in the superficial parts below the renal artery wall, its activity and the occurrence of hypertension and maintenance are closely related, in partial renal artery radiofrequency ablation can damage the renal sympathetic nerve tissue without involving other abdominal, pelvic or lower extremities. 疗效方面,研究经过12月的观察可知,治疗后I个月时,病人血压明显降低,3个月时其血压进一步降低,I年时血压降低的效果依然非常显著,同时亦未发现明显的神经再生。 Terms of efficacy, study after observing December found that when the treatment I months, the patient's blood pressure decreased, blood pressure further reduced at 3 months, when I in the blood pressure lowering effect of still very significant, but has not found significant neurological regeneration. 由此可见,这种疗法方法简便而安全。 Thus, this treatment method is simple and safe.

[0005]因此,利用去肾交感神经射频消融导管系统从肾动脉管腔内传输射频能量,消融环绕肾动脉的肾传入交感神经和肾传出交感神经的研究和报道日益增多。 [0005] Thus, the use of radiofrequency ablation catheter to the renal sympathetic nervous system from within the renal artery lumen transmit radio frequency energy ablation of renal sympathetic nerves around the renal artery afferent and efferent renal sympathetic nerve studies and reports are increasing. 最初的射频消融导管多为单电极的结构,为了切断围绕肾动脉的肾交感神经,必须多次环绕肾动脉进行多次消融,这需要重复对抵在肾动脉内膜处的消融电极(发射器)进行定位,且需要多次发生射频,对导管操作的要求较高,也可能会漏掉一些肾交感神经,导致治疗不完全。 First radiofrequency catheter ablation for the structure of a single multi-electrode, in order to cut around the renal sympathetic nerve renal artery, renal artery must be repeatedly performed a plurality of times around the ablation, which need to be repeated (the emitter contact ablation electrode at the renal artery intima ) to locate, and RF needs to happen many times higher requirements for the operation of the catheter, it may miss some of the renal sympathetic nerves, leading to incomplete treatment. 为了达到更好的治疗效果,人们尝试采用不同的方法和技术,例如,用肾动脉消融导管进行射频消融治疗时,医生操纵手柄将消融导管的远端拉弯使之与肾动脉血管壁贴合,同时转动手柄上的旋扭来控制消融导管远端的转动,移动消融位置,达到在不同部位进行消融,然而,通常在对肾动脉上的交感神经消融时,必须设定较高的功率和高的阻抗才能打断肾动脉血管内壁的交感神经,射频消融时阻抗高达300 Ω,因此对血管内壁损伤很大。 In order to achieve better therapeutic effect, it has been tried using different methods and techniques, for example, the renal artery with radiofrequency ablation catheter ablation treatment, the doctor bar handle of the ablation catheter distal end bending so bonded with renal arterial wall while rotating the control knob on the handle to the distal end of the ablation catheter is rotated, the moving position of the ablation, to achieve ablation at different sites, however, usually when the sympathetic nerve renal artery ablation, and must be set higher power high impedance sympathetic to break the blood vessel wall of the renal artery, up to 300 Ω impedance when radiofrequency ablation, therefore a lot of blood vessel wall injury. 例如,研发人员尝试采用将电极嵌入到肾动脉消融导管远端的球囊上来多点同时进行消融(如VESSIX公司的肾动脉消融导管),但是采用球囊导管的这种方式进行去肾交感神经射频消融,将在射频消融的过程中阻碍肾动脉的血流,如果手术时间过长,将会损伤肾脏功能,而且该产品工艺复杂,成本高。 For example, researchers try to use the ablation electrode is inserted into the renal artery balloon catheter distal end up multi-point simultaneous ablation (e.g. VESSIX ablation catheter's renal artery), but this approach is to use a balloon catheter renal sympathetic nerve radiofrequency ablation, will hinder the renal artery during radiofrequency ablation of the blood flow, if the operation time is too long, will damage kidney function, and the product process is complicated and costly. 例如,专利号为ZL200920172984.6的中国专利提供了一种螺旋环状肾动脉肾交感神经射频消融电极导管,其采用螺旋状的消融电极,对血管壁形成一个非封闭环的连续接触。 For example, Chinese patent No. ZL200920172984.6 is to provide a spiral cyclic renal sympathetic nerve renal artery radiofrequency ablation electrode catheter ablation using a spiral electrode is formed on the vessel wall a closed continuous non-contact ring. 但此专利只有一根固定直径的螺旋电极,使用时需先行股动脉穿刺,在X光造影机透射下,根据肾动脉造影结果,再从不同直径的产品中选出适合患者的产品。 However, this patent only a fixed diameter helical electrode, when used for an advance femoral artery, under X-ray imaging machine transmission, according to the renal artery angiography, a patient will then select the appropriate product from products of different diameters. 患者痛苦时间长,手术程序复杂,医生的操作难度大。 Patients with pain for a long time, surgical procedures are complicated and difficult to operate large physician. 现有技术中还有采用治疗心律失常的消融导管来消融肾动脉上的交感神经,以达到治疗顽固性高血压的目的,此种消融导管直径较粗大,在肾动脉血管内操纵不方便,而且消融面积较大,对肾动脉造成较大的损伤。 There are prior art treatment of arrhythmia using ablation catheter to ablate the sympathetic nerve renal artery, in order to achieve treatment of refractory hypertension, such large diameter ablation catheter coarse convenient manipulation within the renal artery, and ablation area is large, resulting in greater damage to the renal arteries.

[0006] 因此,现在急需一种能够减小对肾动脉的损伤,医生操作方便,并且同一规格可适用不同患者的射频消融导管。 [0006] Accordingly, an urgent need capable of reducing damage to the renal arteries, convenient for doctors to operate, and the same specifications applicable to different patients RF ablation catheter.
