  • Patent number: 10625068
    Abstract: A breakaway connector generally includes a first valve having a first rotating-type fluid control member, and a second valve that is attachable to the first valve and has a second rotating-type fluid control member. Each of the fluid control members has an open position in which fluid is permitted to flow through the respective valve, and a closed position in which fluid is prevented from flowing through the respective valve. Each one of the valves is configured to engage the fluid control member of the other one of the valves to move the fluid control member from the open position to the closed position upon detachment of the valves from one another.

  • Publication number: 20200060800
    Abstract: A multi-laminar repair matrix for repairing a tissue defect may comprise a top patch and a bottom compliant patch. The bottom compliant patch may be compressed and sized to fit through a tissue defect, and expand to a substantially planar state after being implanted to the tissue defect. The top and/or bottom patch may include adhesives. A tool for implanting a patch to a tissue defect may include a shaft, a plurality of arms pivotally connected to the shaft, and a control. The control may be configured to radially expand the plurality of arms upon actuation of the control.

  • Publication number: 20060129056
    Abstract: Methods, systems, and articles of manufacture provide for wireless communications of brain signals from electrode implants to an external receiver for analysis of the brain signals. The analyzed brain signals are used to locate abnormal brain activity in a subject, such as epileptic seizure foci, or to localize task-specific brain activity.

  • Publication number: 20050119687
    Abstract: Embolic devices and materials include an expansible polymer, and magnetically responsive material that allow the embolic devices and materials to be guided into, and held within, vascular defects, while the expansible polymer expands. In some embodiments, the expansion of the expansible polymer reduces the density of the magnetic material, so that subsequent magnetic surgery and magnetic imaging procedures can still employed.
