  • Publication number: 20230414350
    Abstract: A prosthetic implant delivery assembly includes a prosthetic implant and a catheter. The prosthetic implant includes a plurality of apices with apertures. Each apex of the plurality of apices is circumferentially-spaced apart relative to an adjacent apex. The catheter includes a plurality of arms and a plurality of locking elements. Each of the arms includes an opening configured to receive a respective apex of the prosthetic implant. Each of the locking elements is configured to extend through the aperture of a respective apex of the prosthetic implant. A length of at least one of the locking elements is different than a length of another locking element such that when the prosthetic implant is coupled to the catheter by the locking elements, a longitudinal axis of the prosthetic implant can be held at a tilted position relative to a longitudinal axis of the catheter.

  • Publication number: 20230390060
    Abstract: A delivery apparatus for delivering a prosthetic implant includes a handle and a shaft assembly having an inner shaft and an outer shaft. A carriage member is disposed within a cavity of the handle and coupled to the outer shaft. An annular groove to receive a seal member is defined within the carriage member by a proximal end of the outer shaft and a stepdown shoulder formed within the carriage member. The inner shaft extends through a lumen of the outer shaft and includes one or more fluid ports that fluidly connect a lumen of the inner shaft to the lumen of the outer shaft. The implant is coupled to the inner shaft by a frame connector having a recess to receive a connector tab of the implant. The recess includes an undercut wall that transfers tensile force applied to the connector tab to radial force on the connector tab.

  • Patent number: 11779460
    Abstract: A prosthetic implant delivery assembly includes a prosthetic implant including an expandable stent and a catheter for delivering the prosthetic implant. The expandable stent includes apices circumferentially-spaced apart relative to each other. At least some of the apices include an aperture disposed therein. The catheter includes arms disposed at an end of a shaft, and the arms are moveable between a radially compressed state and a radially expanded state via a sheath. The arms each include a hook portion for releasably engaging the apertures of the apices. The arms are configured to move from the radially compressed state to the radially expanded state when the plurality arms is exposed from within the sheath such that the hook portion disengages from the apices of the prosthetic implant and releases the expandable stent from the catheter.

  • Patent number: 6057858
    Abstract: Method and apparatus for rendering characters on one or more output devices using multiple media fonts; one type of a multiple media font being a multiple color font ("MCF"). An MCF is a scalable font (a font used to render characters in multiple sizes and output device pixel resolutions) that enables the use of one or more types of color scheme (color design) data and character shape data in conjunction with one or more types of transformation data (shapes and visual looks) to render characters. Inventive multiple media fonts can be embodied for use: (a) in coordination with present operating systems; (b) as an annex to applications programs; (c) in coordination with, or as an integral part of, an operating-environment; and (d) over the Internet or other computer networks.
