Abstract: A prolapse prevention device formed by a continuous wire-like structure having a first end and a second end disconnected from each other. The continuous wire-like structure of the prolapse prevention device is substantially straight in a delivery configuration. The prolapse prevention device in a deployed configuration includes a centering ring of the continuous wire-like structure configured to seat adjacent to and upstream of an annulus of a heart valve in situ, a vertical support of the continuous wire-like structure which extends from the centering ring and includes an apex configured to seat against a roof of an atrium in situ, and a leaflet backstop of the continuous wire-like structure extending radially inward from the centering ring and configured to contact at least at least a first leaflet of the heart valve in situ to exert a pressure in a downstream direction on the first leaflet to prevent the first leaflet from prolapsing into the atrium.

Abstract: An introducer assembly includes a plurality of selectable side holes through which a fluid can be delivered. In some examples, an introducer assembly includes an outer elongated body defining a plurality of outer body side holes and an inner elongated body defining a plurality of inner body side holes. The inner elongated body is configured to rotate relative to the outer elongated body between a first rotational orientation in which a first subset of outer body side holes aligns with a first subset of inner body side holes and the inner elongated body blocks fluid flow out of the outer elongated body through a second subset of outer body side holes, and a second rotational orientation in which the second subset of outer body side holes aligns with a second subset of inner body side holes and inner elongated body blocks fluid the first subset of outer body side holes.

Abstract: A laryngoscope includes a blade having a distal end and a proximal end, wherein a blade includes a curved portion adjacent the distal end, a housing within the blade adjacent the curved portion, a light source positioned within the housing, and a handle adjacent the proximal end.

Abstract: An aerial delivery device which includes a frame, a top skin, a bottom skin, and a core associated with the top skin, and bottom skin. The core includes a spatial arrangement of, for example, geometric cells, having a cavity defined by walls which extend at least partially between the top skin and the bottom skin. A frame that provides a substantially contiguous boarder around a perimeter of the core may be included. The present invention includes a method of assembly, maintenance, and/or repair of an aerial delivery device, wherein a top skin, a bottom skin, an aerial delivery device frame, and/or additional parts associated with aerial delivery, are associated with one another and/or the core material or replacement core material and device elements.
