  • Hemocompatibility of superhemophobic titania surfaces
    Patent number: 11484630
    Abstract: In this work, we investigated the blood platelet adhesion and activation of truly superhemophobic surfaces and compared them with that of hemophobic surfaces and hemophilic surfaces. Our analysis indicates that only those superhemophobic surfaces with a robust Cassie-Baxter state display significantly lower platelet adhesion and activation. The understanding gained through this work will lead to the fabrication of improved hemocompatible, superhemophobic medical implants.
    Type: Grant
    Filed: April 17, 2018
    Date of Patent: November 1, 2022
    Assignee: Colorado State University Research Foundation

  • Surface treatments for vascular stents and methods thereof
    Patent number: 9597434
    Abstract: Surface modified medical devices with nanotubes and polyelectrolyte multilayers, methods of promoting endothelialization, and methods of modifying a medical device surface are disclosed. Nanotubes may be formed on the surface of the medical device and may further be coated with polyelectrolyte multilayers of a polycation and a polyanion. The surface modification is characterized by a nanopattern on the surface of the medical device, with biomimetic properties.
