Patent number: 11925558Abstract: Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. A protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.Type: GrantFiled: May 26, 2020Date of Patent: March 12, 2024Assignee: The United States of America, As Represented By The Secretary, Department of Health and Human ServicesInventors: June-Hong Kim, Robert J.

Patent number: 10835710Abstract: Disclosed herein are segmented MRI-compatible interventional devices, such as catheters and guidewires, that provide desired mechanical properties while avoiding undesired interactions with MRI fields. Disclosed devices can include helical wires with insulated breaks at intervals along each wire so that the insulated wire segments are individually short enough to avoid substantial resonance and heat being generated in the wires due to an applied MRI field. The segmented wires can be organized into a braided/woven tubular configuration or a non-braided intercalated/parallel tubular configuration that provides the desired mechanical properties similar to conventional metallic braided catheters. The helical wire segments can be insulated such that the wires do not touch each other at points where they cross over each other.Type: GrantFiled: September 14, 2016Date of Patent: November 17, 2020Assignee: THE UNITED STATES OF AMERICA, AS REPRESENTED BY THE SECRETARY, DEPARTMENT OF HEALTH AND HUMAN SERVICESInventors: Robert J.
