20150272737 | TRANSCATHETER MITRAL VALVE STENT FRAMES - A prosthetic heart valve may include a stent having an inflow end, an outflow end, a collapsed condition, and an expanded condition. The prosthetic valve may also include a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets. The prosthetic valve and/or stent may include features to anchor the prosthetic valve to a native valve annulus and to seal the prosthetic valve with respect to the native valve annulus, such as planar and/or nonplanar annular sealing members coupled to ends of the stent. The stent may include one or more circumferential rows of anchor members or hooks extending radially outwardly from the stent. These hooks may be configured to extend in a particular direction when the stent is in the collapsed condition to facilitate resheathing of the stent if, upon deployment, a user determines the prosthetic heart valve is not positioned optimally. | 10-01-2015 |
20150327995 | TRANSCATHETER VALVE WITH PARAVALVULAR LEAK SEALING RING - A prosthetic heart valve includes a collapsible and expandable stent extending from an inflow end to an outflow end and a plurality of prosthetic valve leaflets coupled to the stent. The prosthetic heart valve may also include a sealing ring coupled to the inflow end of the stent, the sealing ring comprising a tube extending circumferentially around the inflow end of the stent. The tube may be formed from a wire coiled into a repeating shape, such as a rectangle or a diamond, so that the tube is collapsible. A covering may at least partially surround the tube. The sealing ring may include a first filler positioned within the tube and/or a second filler positioned between the tube and the covering. | 11-19-2015 |

20160095701 | Bi-Leaflet Mitral Valve Design - A prosthetic mitral valve includes a collapsible and expandable elliptical or āDā-shaped stent. The stent includes first and second commissure attachment features and a collapsible and expandable valve assembly disposed therein. The valve assembly includes two leaflets, each leaflet having a first edge operably coupled to the stent and a second free edge. Each leaflet may include first and second tabs connecting first and second ends of the first and second edges, respectively. Each leaflet includes a height measured from a midpoint of the first edge to a midpoint of the second edge and a width measured from a junction of the first edge with the first tab to a junction of the first edge with the second tab. The ratio of the height to the width may be between about 0.4 and about 0.65. | 04-07-2016 |

20100258691 | DETACHABLE SCREEN PROTECTOR ASSEMBLY FOR LARGE FLAT PANEL DISPLAYS - A screen protector assembly for use with a flat panel display having a display panel located on a front surface thereof. The screen protector assembly comprises a transparent screen panel having a pair of slots formed therein adjacent a top edge of the screen panel and a pair of c-shaped hanger clamps for detachably securing the screen panel to the flat panel display. Each clamp hanger comprises a top portion for engaging a top surface of the flat panel display, an arm extending downwardly from the top portion, and a tail portion end for providing a clamping force between the screen panel and the back surface of the front panel display. The arm has a tab protruding rearwardly from the arm with an upwardly extending hook forming a neck for supporting a top surface of the slot. The tab is shaped to fit within the slot of the screen panel such that a top surface of the slot rests on the neck and hangs thereform. A space is formed between a rear surface screen and a front surface of the flat panel display to permit airflow therebetween for ventilation of the display. | 10-14-2010 |
