  • Publication number: 20220008194
    Abstract: Systems, apparatuses, and methods for treating native heart valves are disclosed herein. A system for delivering a prosthetic device into a heart of a patient includes an elongated catheter body and a delivery capsule. The delivery capsule can be hydraulically driven to deploy at least a portion of a prosthetic heart valve device. The delivery capsule can release the prosthetic heart valve device at a desired treatment site in a patient.

  • Patent number: 10741759
    Abstract: A diffusive memristor device and an electronic device for emulating a biological synapse are disclosed. The diffusive memristor device includes a bottom electrode, a top electrode formed opposite the bottom electrode, and a dielectric layer disposed between the top electrode and the bottom electrode. The dielectric layer comprises silver doped silicon oxynitride (SiOxNy:Ag). In an alternate implementation, the dielectric layer comprises silver doped silicon oxide (Ag:SiO2). An electronic synapse emulation device is also disclosed. The synapse emulation device includes a diffusive memristor device, a drift memristor device connected in series with the diffusive memristor device, a first voltage pulse generator connected to the diffusive memristor device, and a second voltage pulse generator connected to the drift memristor device. Application of a signal from one of the first voltage pulse generator or the second voltage pulse generator allows the synapse emulation device to exhibit long-term plasticity.

  • Publication number: 20060169116
    Abstract: A device for cutting pieces of material comprising a base, a bridge assembly and a lever arm. The bridge assembly includes a gear assembly operatively connected to the base. The lever arm is coupled to the gear assembly, and a linking member is coupled to the gear assembly; A material clamp is operatively connected to the linking member, and a cutting blade is operatively connected to the linking member. The movement of the lever arm of the first position towards the second position results in the gear assembly and the linking member cooperating to cause the material clamp to move towards the base and affix the position of pieces of material located between the base and the material clamp. The cutting blade comes into contact with and severs the pieces of material after the position of the pieces of material has been fixed by the material clamp.
