新型海波管抗扭结性能提高,确保血管整形手术安全

在血管整形手术过程中,通常必须施加巨大的力量,以引导导管穿过动脉。有时,病变部位阻塞严重,致使导管在动脉内难以行进,甚至会使海波管扭结。在这种情况下,很难正确地把球囊和支架放在适当位置上,而且扭结的海波管可能会影响球囊放气,导致球囊移除困难并增加病人的危险。严重时,海波管可能会折断,需要通过手术或其他复杂的方式取出断裂的管材。

Creganna公司推出的新型海波管抗扭结性能据称比现有产品高出40%。

美国波士顿Brigham & Women医院医学信息系统主任Frederic Resnic博士说: 放置支架或球囊的成功与否受若干因素影响,其中包括血管弯曲状态、血管钙化以及血管狭窄的程度。如果有力量过大会使导管轴扭结的疑虑,我会用另外的导管来代替。

Resnic博士参加的最新研究表明,新型海波管提高了抗扭结性能,能够减少外科手术时间,并且使心脏介入疗法更安全、更便宜。该项研究由Cambridge Consultants公司(英国剑桥; www.cambridgeconsultants.com)于去年底完成,对德国、英国和美国许多著名心脏病专家做了深入专访,他们一致认为需要改善海波管的抗扭结性能,否则导管很难穿过严重阻塞的扭曲动脉。Resnic博士表示, 提高海波管抗扭结性能,将有助于手术的成功,心脏病专家能够放心地使用更大力量推动支架。

该项研究发布之后,Creganna Medical Devices公司 (爱尔兰,Galway Parkmore West; www.creganna.com)宣布,它将生产比现有产品抗扭结性能提高40%的新型海波管。该公司在上述研究中与Cambridge Consultants公司合作,根据心脏病专家和医学设备制造商的需要,开发了PoleVault海波管。除改进抗扭结性能以外,该产品还能加快球囊放气速度。由于不易扭结,可让医生选择内径更小的导管。加快球囊放气速度能将病人的损伤减小到最低限度。PoleVault有良好的包装性能,生产组装时不易损坏。

2004年,仅美国就有500多万例心脏介入治疗,病人和医生对技术进步的要求刺激了药物缓释支架等产品的发展。但是PoleVault海波管的研发表明,即使是简单的设备也同样有发展的空间。

Cambridge Consultants公司的顾问Clare Beddoes与Creganna公司的Maura Leahy共同参与了此研究。她表示,技术创新不仅要面向高端市场,而且要重视看似简单的部件,这样才能取得最理想的成果。认真听取临床医生的意见,有助于我们发现影响医学设备性能的隐藏问题,从而对老产品进行创新,以便为医生和病人节省时间和金钱。
