  • Publication number: 20240293231
    Abstract: An anchor assembly is configured to implant a cardiac anchor into a heart wall of a patient to anchor a suture configured to extend from a valve leaflet of the heart as an artificial chordae. The anchor assembly can include an anchor hub defining an open interior and a helical coil extending distally from the anchor hub and having a sharpened tip configured to embed the helical coil into the heart wall upon rotation of the helical coil. A spring can be disposed within the open interior of the anchor hub. Compressing the spring distally can create an open space within the open interior of the anchor hub for a suture extending through the anchor hub to slide freely and releasing compression on the spring can cause the spring to expand in a proximal direction to clamp the suture within the open interior of the anchor hub.

  • Publication number: 20140036619
    Abstract: A material processing machine having a rotating element formed of a core rotatable about a generally vertical axis, and a top cap having a pair of facets which abut together at a join line. The join line extends downward from perpendicular to the generally vertical axis at an angle. The core has a continuous outer wall that is substantially vertical, and the facets extend inward from the outer wall to the join line at a non-perpendicular angle. Each of the facets extends inward from the outer wall to the join line at an angle that is different from angle of the other facet.

  • Publication number: 20140008253
    Abstract: A condensate sensor enclosure to house an electromechanical control system to limit the level of condensate within a drain pan of an air conditioning system comprising a control system compartment and cover coupled together by a coupling assembly including a first coupler and a second coupler to enclose the electromechanical control system therein and a pair of probe housings each extending downwardly from the bottom of the control system compartment to operatively receive and house at least a portion a corresponding pair of electrically conductive sensor probes operatively coupled to the electromechanical control system to sense when the condensate within the drain pan reaches a predetermined level.
