Patent number: 11452603Abstract: An intravascular support device includes a support or reshaper wire, a proximal anchor and a distal anchor. The support wire engages a vessel wall to change the shape of tissue adjacent the vessel in which the intravascular support is placed. The anchors and support wire are designed such that the vessel in which the support is placed remains open and can be accessed by other devices if necessary. The device provides a minimal metal surface area to blood flowing within the vessel to limit the creation of thrombosis. The anchors can be locked in place to secure the support within the vessel.Type: GrantFiled: July 9, 2021Date of Patent: September 27, 2022Assignee: Cardiac Dimensions Pty. Ltd.Inventors: Mark L. Mathis, Gregory D. Nieminen, Nathan Aronson, Garrett R. Beget
