  • Publication number: 20190142579
    Abstract: A mitral valve repair system includes a delivery sheath, a mitral valve repair device, and an actuator. The mitral valve repair device is disposed in the delivery sheath in an extended condition. The mitral valve repair device is movable out of the delivery sheath while in the extended condition. The actuator is coupled to the mitral valve repair device, such that retracting the actuator reduces a length of the mitral valve repair device from the extended condition.

  • Publication number: 20190142580
    Abstract: A mitral valve repair system includes a delivery sheath, a mitral valve repair device, and an actuator. The mitral valve repair device is disposed in the delivery sheath in an extended condition. The mitral valve repair device includes a pair of barbed clasps. The barbed clasps are in a closed condition while the mitral valve repair device is in the extended condition in the delivery sheath.

  • Patent number: 9848755
    Abstract: A device and method for handling fluids released during a procedure employs a floormat with opposing surfaces. The floormat is formed, at least in part, of compressible and resilient material. An absorbent sheet is attached to one of the opposing surfaces of the floormat. At least part of the absorbent sheet is stacked to extend peripherally beyond the floormat. The floormat and absorbent sheet are placed where a user is expected to stand during the procedure, and are stacked with at least part of the absorbent sheet extending beyond the floormat. A user stands atop the floormat and absorbent sheet during at least part of the procedure. During the procedure, fluids that fall onto the absorbent sheet are absorbed into it. The floormat and absorbent sheet are vacated and discarded before starting another procedure.

  • Patent number: 9515910
    Abstract: Implementations described and claimed herein provide systems and methods for balancing network loads across distinct provider networks using enriched network traffic flow data. In one implementation, network traffic flow data representative of network traffic exchanged between a first provider network and a second provider network is generated. The network traffic flow data is enriched using at least one enrichment feed. A network load indication for the first provider network is calculated using the enriched network traffic flow data. The network load indication is a function of a bandwidth measurement and a distance measurement.

  • Patent number: 9497122
    Abstract: Implementations described and claimed herein providing systems and methods for modeling and visualizing interconnection relationships between a first provider network and a partner. In one implementation, a partner of a provider network is defined by at least one interconnection point where network traffic may be exchanged between the provider network and the partner. An interconnection relationship is generated based on the at least one interconnection point. The interconnection relationship is modeled.

  • Patent number: 9321242
    Abstract: Fluids are handled with a discardable floormat stacked with an absorbent sheet that extends beyond the floormat. The floormat is compressible and resilient, and may be a single or multiple sections. Atop the floormat are trip-avoiding channels feeding a gutter on a side whose height equals or exceeds the opposite side. The floormat has a border region, and a greater central region that is flat except for the channels. The border region has a height not exceeding that of the gutter, which has a draining outlet. In some cases the gutter is mostly free to fill fully and form a single exposed stream. In other cases, tubing occupies most of the gutter length, and has some intake apertures. Fluid entering the tubing can be sucked out, while fluid arriving at the absorbent sheet will be absorbed.
