  • Patent number: 11950784
    Abstract: Described here are devices for closing one or more tissues, and handles for controlling these devices. Generally, the devices described here comprise a snare loop assembly, wherein the snare loop assembly comprises a snare and a suture loop, and a handle for controlling the snare loop assembly. In some variations the snare loop assembly may comprise a retention member that may releasably connect the suture loop to the snare. In other variations the devices comprise one or more force-reducing suture locks to help prevent the suture loop from inadvertently disengaging from the snare loop assembly. In still other variations, the excess-suture management features. The handles described here may be configured to remove excess suture from a suture loop, and may also be configured to release the suture loop from the snare loop assembly.

  • Publication number: 20070045359
    Abstract: A vertical blade in the spout of a container, on the inside lip of a container or across the top diameter of a container. The blade forms a triangle in the center of the spout. In a spoutless container, the blade extends from the top lip horizontally inside the container for up to two inches, then diagonally down to the inside of the container. Placed across the diameter of a container, the top of the blade is flush with the top of the container and extends down to a maximum of two inches, making a rectangle across the container. Splattering is prevented because liquid is cut, then pulled toward the center. Cohesion pulls liquid toward the blade. Adhesion brings the liquid together after it passes the blade.
