Patent number: 11963712Abstract: A transapical removal device that can be deployed in a catheter procedure to capture for removal or alteration a mitral valve clip or heart tissue, such as the anterior leaflet of the mitral valve, and methods of use are disclosed. The removal device includes a delivery catheter configured to be deployed near a mitral valve using a guide catheter. The delivery catheter has a snare head at the distal end, which assumes a collapsed state during movement of the delivery catheter through the guide catheter and deployed state for capturing a mitral valve clip or anterior leaflet. The snare head has one or more ablation delivery catheters configured to ablate tissue surrounding the pre-positioned mitral valve clip or anterior leaflet. In some arrangements within the scope of the present disclosure, the removal device includes a deployment mechanism for deploying a new transcatheter valve into the mitral valve.Type: GrantFiled: June 20, 2017Date of Patent: April 23, 2024Assignee: Evalve, Inc.Inventor: Eduardo De Marchena

Publication number: 20140074147Abstract: A system and method for preventing the movement of emboli away from a vascular region. The system generally includes a medical device having a clot capture assembly, a shaft, and a sheath disposed about the shaft, and a console. The clot capture assembly includes a first and second clot capture element, each of which is disposed between the shaft and sheath when in a first position. When the sheath is retracted, the first and second clot capture elements expand into a second position, at least a portion of the first and second clot capture elements being substantially in contact with at least a portion of an interior surface of a section of vasculature.Type: ApplicationFiled: May 23, 2012Publication date: March 13, 2014Applicant: University of Miami Intellectual Property Strategy and Licensing IPSLInventor: Eduardo De Marchena

Publication number: 20110184298Abstract: A system and method for measuring heart rate variability (HRV). The system includes at least one biosensor operable to measure at least one signal from the heart. A bioamplifier is also included, the bioamplifier is in communication with the at least one biosensor. The bioamplifier amplifies the at least one signal into at least one amplified analog signal. A portable device is included, the portable device is in communication with the bioamplifier and operable to digitize the at least one amplified signal into one or more digital signals and measure inter-beat intervals from the one or more digital signals and calculate HRV from the measured inter-beat intervals. A database is also included in communication with the portable device, wherein the measured HRV is indexed in the database by one or more criteria.Type: ApplicationFiled: September 25, 2009Publication date: July 28, 2011Applicant: University of MiamiInventors: Eduardo De Marchena, Suresh Atapattu

Patent number: 7957819Abstract: A low profile transvenous electrode system for use in an emergency to sequentially pace both the atrium and ventricle of the heart in a dual chamber mode that includes a plurality of pre-formed, pre-shaped resilient insulated electrical wires bundled together in a tubular, flexible retaining sheath that is used as a guide and delivery system during insertion and removal of the electrode system. When the sheath is retracted, it allows the wires to escape from the sheath and because of their pre-formed shape, each wire having memory, the wires spread out and contact the endocardial surfaces inside the ventricle and atrium chambers. Each of the wires have ball tips to provide high current density and sensitivity.Type: GrantFiled: December 19, 2006Date of Patent: June 7, 2011Inventors: Frank Avellanet, Eduardo de Marchena

Publication number: 20090099410Abstract: The surgical implantation of a link, which may be in the form of a tether or a looped band, is proposed to connect and reduce the spacing between papillary muscles, to reduce dilation of the left ventricle. The implanted link thus improves heart function by reducing left ventricular failure.Type: ApplicationFiled: May 19, 2006Publication date: April 16, 2009Inventor: Eduardo De Marchena

Publication number: 20090082619Abstract: The surgical implantation of a link, which may be in the form of a tether or a looped band, is proposed to connect and reduce the spacing between facing walls of the left ventricle, to reduce dilation of the left ventricle. Decreasing the distance between the facing portions of the ventricle may also more appropriately align the chordal apparatus to decrease mitral regurgitation. The implanted link thus improves heart function by reducing left ventricular failure.Type: ApplicationFiled: December 2, 2008Publication date: March 26, 2009Inventor: Eduardo DE MARCHENA
