Patent number: 10130472Abstract: A system for treating mitral valve regurgitation includes a tensioning device having a plurality of helical anchors and a tensioning filament. One embodiment of the invention includes a method for attaching a tensioning device to the annulus of a mitral valve in a trans-leaflet configuration, and applying a tension force to the tension filament in order to exert force vectors on the annulus, thereby reshaping the mitral valve annulus so that the coaption of the anterior and posterior leaflets of the mitral is improved during ventricular contraction.Type: GrantFiled: August 25, 2016Date of Patent: November 20, 2018Assignee: Medtronic Vascular, Inc.Inventors: Patricia O'Beirne, Nasser Rafiee

Patent number: 8873900Abstract: An apparatus and method for determining an expanded diameter of a catheter balloon. An optical sensor includes an elongated optical fiber with at least one diffraction grating formed in a core of a distal portion thereof. The fiber distal portion is coupled to the inflatable balloon. Broadband light is transmitted to the diffraction grating by an optical interrogator. A portion of the light is reflected from the diffraction grating and is received by a wavelength detector. The wavelength of the reflected portion of light is dependent on the strain applied to the diffraction grating. The wavelength detector determines the strain in the balloon and correlates the strain to the diameter of the balloon.Type: GrantFiled: April 21, 2011Date of Patent: October 28, 2014Assignee: Medtronic Vascular, Inc.Inventors: Patricia O'Beirne, Aram Jamous, John Kelly

Patent number: 8016799Abstract: A catheter is disclosed that has a detachable tip for delivery of a therapeutic substance to a chronic total occlusion (CTO) within a body vessel. The tip is made from a biodegradable material and includes an active agent dispersed therethrough. The detachable tip pierces into the calcified lesion, detaches from the catheter, and remains embedded within the lesion as the tip degrades, thereby releasing the active agent. The active agent is a therapeutic substance effective to treat of a CTO. The active agent may be a drug, an enzyme, bacteria, or a parasite that degrades or softens the calcified lesion.Type: GrantFiled: April 22, 2008Date of Patent: September 13, 2011Assignee: Medtronic Vascular, Inc.Inventors: Stephen Nash, Patricia O'Beirne, David Johnson, Stephen Gormley, Grace Kelly
