    Abstract: Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.

  • Publication number: 20160032252
    Abstract: The invention is in the field of virology and relates to the deformed wing virus (DWV). A new strain of deformed wing virus (DWV) has been identified that is predominant in bees infested with Varroa mites. This particular strain of DWV can be used in diagnostics to identify at risk colonies. Also, inhibitors of the particular strain may be used in the treatment and/or prevention of DWV.

  • Publication number: 20150182334
    Abstract: A heart valve delivery system is provided wherein a prosthetic valve is carried on a valve catheter inside a delivery sleeve. A step balloon protrudes from the delivery sleeve and provides a tapered surface for facilitating advancement through a body vessel. The step balloon also aids in crossing the leaflets of a native valve. After the prosthetic valve is positioned within the native valve, the delivery sleeve is retracted to expose the prosthetic valve. If necessary, the step balloon may be expanded to securely seat the prosthetic valve at the site of the native valve. The prosthetic valve is preferably coupled to the valve catheter by a plurality of flexible extension arms which allow the prosthetic valve to be collapsed after initial deployment such that the prosthetic valve may be repositioned if necessary.

  • Publication number: 20140267525
    Abstract: An embodiment of an applicator wheel, which applies ink to embossed designs on gutters. This is accomplished during manufacturing process of gutter as gutters exit any gutter machine. The embodiment attaches to any gutter machine, and by a simple process applies ink or paint to any design that is raised/embossed. Ink is held in a well, which distributes through a roller to a transfer roller to applicator wheel pad. Two offset rims keep the pad at correct distance from un-embossed portion of gutter and applicator wheel pad paints only the embossed portion of a design. (FIG. 10). Between flexibility of pad and this offset rim distance, ink is applied only to raised/embossed portion of any design by application wheel roller, rolling along the gutter as it exits gutter machine. Another embodiment applies a design directly onto un-embossed gutters. Again, using the applicator wheel, except this embodiment uses a different applicator wheel pad with a design on the pad. (FIG. 11).

  • Patent number: 8777968
    Abstract: A tissue fastening device includes a suture clip holder and a suture cutter. A suture clip can be releasably secured to the suture clip holder, and a suture line or lines can pass through the clip and adjacent the suture cutter. A first movement of a control handle causes the suture clip to be released from the suture clip holder, and a second movement of the control handle causes the suture cutter to cut the suture line or lines. The first movement is different from the second movement. The first movement can be rotational, with the second movement being longitudinal. Alternatively, the first movement can be longitudinal, with the second movement being rotational. The device may include a main body, an inner body, and an outer body.

  • Publication number: 20140058502
    Abstract: Embodiments of the present disclosure provide a delivery apparatus for delivering a prosthetic heart valve to a native valve site via the human vasculature without the need for a separate introducer sheath. The delivery apparatus is particularly well-suited for advancing a prosthetic valve through the aorta (i.e., in a retrograde approach) for replacing a stenotic aortic valve.
