StentEx – Surgical instrument for removal of vascular stents

The present invention provides a stent remover for open surgery which can be used to safely remove a stent without causing tissue damage. In a first step, at least three wires are threaded through the mesh of one end of the stent. Then, all wire ends are fed through a sleeve and fixed with a crimping device. Afterwards, the wires in the sleeve can easily be introduced into the funnel-shaped tube of the stent remover. By operating the turning knob of the device, a uniform and controllable pulling force is exerted to the wires. In this way, the stent constricts evenly and can easily be removed without serious tissue damage. In addition, stent removal with this novel device shortens the operation time, thereby reducing the potential for unforeseen complications. On behalf of RWTH Aachen University, PROvendis offers access to rights for commercial use as well as the opportunity for further co-development.
