  • Patent number: 7077862
    Abstract: Devices and methods for treating heart valves include members that assist the valve in closing during at least a portion of the cardiac cycle. Such devices include members configured to alter the shape of a valve annulus, reposition at least one papillary muscle, and/or plug an orifice of the valve so as to provide a coaptation surface for the valve leaflets.
    Type: Grant
    Filed: June 15, 2004
    Date of Patent: July 18, 2006
    Assignee: Myocor, Inc.
    Inventors: Robert M. Vidlund, Jason E. Kalgreen, Todd J. Mortier, Cyril J. Schweich, Jr., Richard Schroeder, David Kusz
  • Publication number: 20060149123
    Abstract: A splint assembly for placement transverse a heart chamber to reduce the heart chamber radius and improve cardiac function has a tension member formed of a braided cable with a covering. A fixed anchor assembly is attached to one end of the tension member and a leader for penetrating a heart wall and guiding the tension member through the heart is attached to the other end. An adjustable anchor assembly can be secured onto the tension member opposite to the side on which the fixed pad assembly is attached. The adjustable anchor assembly can be positioned along the tension member so as to adjust the length of the tension member extending between the fixed and adjustable anchor assemblies. The pad assemblies engage with the outside of the heart wall to hold the tension member in place transverse the heart chamber. A probe and marker delivery device is used to identify locations on the heart wall to place the splint assembly such that it will not interfere with internal heart structures.

  • Publication number: 20060100699
    Abstract: Devices and methods for improving the function of a valve (e.g., mitral valve) by positioning an implantable device outside and adjacent the heart wall such that the device alters the shape of the heart wall acting on the valve. The implantable device may alter the shape of the heart wall acting on the valve by applying an inward force and/or by circumferential shortening (cinching). The shape change of the heart wall acting on the valve is sufficient to change the function of the valve, and may increase coaptation of the leaflets, for example, to reduce regurgitation.

  • Publication number: 20060036317
    Abstract: Devices and methods for improving the function of a valve (e.g., mitral valve) by positioning a spacing filling device outside and adjacent the heart wall such that the device applies an inward force against the heart wall acting on the valve. A substantially equal and opposite force may be provided by securing the device to the heart wall, and/or a substantially equal and opposite outward force may be applied against anatomical structure outside the heart wall. The inward force is sufficient to change the function of the valve, and may increase coaptation of the leaflets, for example. The space filling device may be implanted by a surgical approach, a transthoracic approach, or a transluminal approach, for example. The space filling portion may be delivered utilizing a delivery catheter navigated via the selected approach, and the space filling portion may be expandable between a smaller delivery configuration and a larger deployed configuration.

  • Publication number: 20050148815
    Abstract: A method and implantation tools for placing a transventricular splint including a tension member. The method includes gaining access to the patient's hearts and identifying entry or exit points for the tension member, marking those locations and delivering the tension member. Anchors for the tension member are also delivered. The length of the tensions member is measured and the walls of the heart drawn together. The pads are secured to the tension member and the tension member is trimmed to length. The pads are secured to the heart surface.
