Physician-modified Steerable Endovascular Catheter.

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.
