Publication number: 20120197389Abstract: 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: ApplicationFiled: April 10, 2012Publication date: August 2, 2012Inventors: Clifton A. Alferness, John M. Adams, Mark L. Mathis, David G. Reuter, Cruz Beeson, Leonard Kowalsky

Patent number: 8182529Abstract: The invention is a method of delivering and deploying a tissue shaping device in a lumen within a patient, with the tissue shaping device including an anchor. In some embodiments the method includes the steps of: inserting a delivery catheter into the lumen; percutaneously delivering the device to a target site within the lumen through a delivery catheter; operating an actuator to expose an anchor; and operating the actuator to lock the anchor. In other, the method includes the steps of: inserting a delivery catheter into the lumen; moving the device from a cartridge into the delivery catheter; delivering the device to a target site within the lumen; operating an actuator to move the delivery catheter with respect to the anchor to expose the anchor; and expanding the anchor.Type: GrantFiled: September 20, 2004Date of Patent: May 22, 2012Assignee: Cardiac Dimensions, Inc.Inventors: Lucas S. Gordon, Mark L. Mathis, Gregory Nieminen, Leonard Kowalsky, Ryan Braxtan, Brian J. Doll
