20130172978 | Tethers for Prosthetic Mitral Valve - This invention relates to the design and function of a single-tether compressible valve replacement prosthesis which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed combats the process of wear on anchoring tethers over time by using a plurality of stent-attached, centering tethers, which are themselves attached to a single anchoring tether, which extends through the ventricle and is anchored to a securing device located on the epicardium. | 07-04-2013 |
20140214159 | PROSTHETIC VALVES AND RELATED INVENTIONS - This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve. | 07-31-2014 |
20140296971 | Alignment Device for Asymmetric Transcatheter Valve - This invention relates to relates to a alignment device for providing the correct valve alignment during deployment of an asymmetrical transcatheter valve while it is being deployed in a patient in need thereof, and methods of use thereof. | 10-02-2014 |
20140296972 | Deployment Compensator for Transcatheter Valve Delivery - This invention relates to a deployment compensator for reducing the expelling force of a compressed transcatheter valve while it is being deployed in a patient in need thereof, and methods of use thereof. | 10-02-2014 |
20140316516 | MULTI-COMPONENT CUFF DESIGNS FOR TRANSCATHETER MITRAL VALVE REPLACEMENT SUBVALVULAR SEALING APPARATUS FOR TRANSCATHETER MITRAL VALVES AND WIRE FRAMED LEAFLET ASSEMBLY - This invention relates to improved devices and methods for deploying and sealing a prosthetic cardiac valve, including (i) a mitral valve with a cuff or atrial sealing gasket formed from tissue or fabric-covered wire or laser cut metal originating from one end of an expandable stent, wherein such cuff or gasket is contoured to fill the zone of coaptation between the commissures of the native valve, (ii) an articulating cuff comprised of a series of radially extending tines having a loop terminus to improve sealing a prosthetic mitral valve against hemodynamic leaking, methods of fitting a prosthetic valve with such an articulating cuff wherein such cuff is contoured to fill the zone of coaptation between the commissures of the native valve, and/or (iii) an expandable leaflet assembly comprising tissue or fabric leaflets extending to cover a wire frame of three or more repeating arches. | 10-23-2014 |
20140324161 | RETRIEVAL AND REPOSITIONING SYSTEM FOR PROSTHETIC HEART VALVE - This invention relates to the design and function of a retrieval device for a prosthetic heart valve for re-positioning or removal of a previously implanted valve prosthesis from a beating heart without extracorporeal circulation using a transcatheter retrieval system. | 10-30-2014 |
20150142103 | MULTI-COMPONENT DESIGNS FOR HEART VALVE RETRIEVAL DEVICE, SEALING STRUCTURES AND STENT ASSEMBLY - This invention relates to the design and function of a device which allows for retrieval of a previously implanted valve prosthesis from a beating heart without extracorporeal circulation using a transcatheter retrieval system, including a guide component to facilitate the compression of the valve and retraction into a retrieval catheter, as well as an improved prosthetic transcatheter heart valve having one or more of: a series of radially extending tines having a loop terminus to improve sealing a deployed prosthetic mitral valve against hemodynamic leaking, a pre-compressible stent-in-stent design, or an articulating cuff attached to a covered stent-valve and a commissural sealing skirt structure attached to the underside of the articulating cuff. | 05-21-2015 |
20150196393 | DELIVERY SYSTEMS AND METHODS FOR TRANSCATHETER PROSTHETIC VALVES - This invention relates to a delivery apparatus and method for deployment of a mitral valve replacement. | 07-16-2015 |
