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

Publication number: 20220211502Abstract: The present invention relates to a tissue shaping device adapted to be disposed in a vessel near a patient's heart to reshape the patient's heart. The device comprises a first anchor and a second anchor adapted to be deployed by a catheter to engage a vessel wall while the first anchor is adapted to resist the compression of a first part of the first anchor and resist the expansion of a second part of the first anchor in response to a compressive force on the first part.Type: ApplicationFiled: March 22, 2022Publication date: July 7, 2022Inventors: Gregory D. NIEMINEN, Carly A. THALER

Patent number: 11285005Abstract: Methods of minimally-invasively treating mitral valve regurgitation. The methods include advancing a device in a collapsed configuration into a coronary sinus, causing a distal anchor of the device to expand, exposing a connecting member of the device, pulling proximally on the device, causing a proximal anchor of the device to expand, and releasing the device.Type: GrantFiled: September 3, 2021Date of Patent: March 29, 2022Assignee: Cardiac Dimensions Pty.
