We demonstrate a simple, intraoperative modification to a 65 cm Beacon Tip Kumpe catheter (Cook Medical) using readily-available components in order to increase its functionality during endovascular procedures. The steerable endovascular catheter has near-spherical range, improving accessibility to challenging anatomy over conventional catheters as demonstrated by our qualitative modeling. In addition, the modification provides structural reinforcement at the catheter tip leading to precise wire advancement. Use of the steerable catheter was demonstrated in vivo during contralateral gate cannulation of an endovascular aneurysm repair, however it holds broad applications in visceral, branched and fenestrated cannulations. Physician-modified devices offer the potential to improve endovascular techniques and reduce additional procedure costs while avoiding regulatory board approval required of novel steerable endovascular devices.
我们展示了一种简单的术中修改方法，用于修改 65 厘米长的 Beacon Tip Kumpe 导管（库克医疗），使用现成的组件来增加其在血管内手术过程中的功能。这种可操纵的血管内导管具有近乎球形的范围，与传统导管相比，提高了对挑战性解剖结构的可达性，这一点已通过我们的定性模型得到证实。此外，这种修改在导管尖端提供了结构加固，从而实现了精确的导丝推进。在血管内动脉瘤修复的对侧门腔插管的体内演示中使用了可操纵导管，但它在内脏、分支和开窗插管中具有广泛的应用。医生修改的设备有可能改进血管内技术并降低额外的程序成本，同时避免了新型可操纵血管内设备所需的监管部门批准。
