Background: Current endovascular procedures to treat vascular diseases use a variety of metallic devices (eg, guidewires, stents, filters and coils). One of the most popular materials used for the endovascular metallic devices is NiTi/nitinol. A nitinol endovascular device having an enhanced rate of endothelialization and neointima coverage as well as an enhanced affinity of the device with a native vascular tissue brings a positive impact on clinical practice.

Materials and Methods: Nitinol sheets were treated with UV irradiation, and the surface energy of each sheet was evaluated by the contact angle …
