  • Patent number: 10646343
    Abstract: A method for improving the function of a valve in the heart of a patient, comprising attaching, to a leaflet of the valve, an element that is responsive to a magnetic field; positioning, outside of the heart of the patient, a coil connected to a source of electric energy; activating the source of electric energy to provide an oscillating current in the coil; and thereby providing an oscillating magnetic field through the coil to effect movement of the element and the leaflet.

  • Publication number: 20170246352
    Abstract: A stent is formed by encasing or encapsulating metallic rings in an inner polymeric layer and an outer polymeric layer. At least one polymer link connects adjacent metallic rings. The stent is drug loaded with one or more therapeutic agent or drug, for example, to reduce the likelihood of the development of restenosis in the coronary arteries. The inner and outer polymeric materials can be of the same polymer or different polymer to achieve different results, such as enhancing flexibility and providing a stent that is visible under MRI, computer tomography and x-ray fluoroscopy.

  • Publication number: 20160287418
    Abstract: The present invention is directed to a flexible expandable stent for implantation in a body lumen, such as a coronary artery. The stent generally includes a series of metallic cylindrical rings longitudinally aligned on a common axis of the stent and interconnected by a series of links which be polymeric or metallic. Varying configurations and patterns of the links and rings provides longitudinal and flexural flexibility to the stent while maintaining sufficient column strength to space the cylindrical rings along the longitudinal axis and providing a low crimp profile, enhanced stent security and radial stiffness.
