    Abstract: Systems, methods and devices are provided for treating heart failure patients suffering from various levels of heart dilation. Such heart dilation is treated by reshaping the heart anatomy with the use of shape memory elements. Such reshaping changes the geometry of portions of the heart, particularly the right or left ventricles, to increase contractibility of the ventricles thereby increasing the stroke volume which in turn increases the cardiac output of the heart. The shape memory elements have an original shape and at least one memory shape. The elements are implanted within the heart tissue or attached externally and/or internally to a surface of the heart when in the original shape. The elements are then activated to transition from the original shape to one of the at least one memory shapes. Transitioning of the elements cause the associated heart tissue areas to readjust position, such as to decrease the width of the ventricles. Such repositioning is maintained over time by the elements, allowing the damaging effects of heart dilation to slow in progression or reverse.

    Abstract: Methods and devices are provided for providing a protective framework for treating an aneurysm with embolic coils and preventing mitigation of the embolic coils from the aneurysm. A dynamically remodelable stent having a first and a second configuration is delivered into the blood vessel patient, such as a human or other animal, and positioned adjacent an ostium of an aneurysm while in the first, linear configuration. The dynamically remodelable stent may then be activated to assume a second, expanded configuration and thereby provide a protective framework spanning the neck of the aneurysm during and after delivery of embolic devices, such as embolic coils, to the aneurysm. The stent can be activated within the body of a patient in a minimally invasive or non-invasive manner such as by applying energy percutaneously or external to the patient's body. The energy may include, for example, acoustic energy, radio frequency energy, light energy and magnetic energy. In certain embodiments, the stent include a shape memory material that is responsive to changes in temperature and/or exposure to a magnetic field.

    Abstract: Methods and devices for reshaping or reforming tissue, such as a mitral valve of a heart, are described. An implant includes a generally flexible body and a plurality of magnetic portions such that the magnetic portions interact to cause a change in the shape of the implant, which, in turn, effects a change in shape of the subject tissue. In one example, at least one implant is positioned within a coronary sinus to affect the shape of the mitral valve annulus. The implant may further include fixation mechanisms for securing the implant within a vessel and may provide for removability after desired deformation of the subject tissue has taken place.

    Abstract: Tissue shaping methods and devices are provided for reinforcing and/or remodeling heart valves. In certain embodiments, magnetic tissue shaping devices are implanted in tissue adjacent heart valve leaflets. The devices are mutually attractive or repulsive so as to remodel the heart tissue and improve heart valve function. In certain other embodiments, one or more tissue shaping devices including shape memory material are implanted in a patient's body within or on tissue adjacent a heart valve leaflet. The shape memory material can be activated within the patient in a less invasive or non-invasive manner, such as by applying energy percutaneously or external to the patient's body. The shape memory tissue shaping devices are implanted in a first configuration and then activated to remember a second configuration that displaces tissue so as to remodel the heart valve geometry and improve heart valve function. In certain other embodiments, a brace is crimped to the base of a heart valve leaflet to support the leaflet and improve valve closure.
