  • Patent number: 10758332
    Abstract: A prosthetic repair system includes a prosthesis for repairing a defect in a tissue or muscle wall. A material delivery device is provided for delivering a material, such as an adhesive material, to a surface of the prosthesis and/or to particular locations between the prosthesis and the tissue or muscle wall to attach the prosthesis to the wall. The delivery device may be coupled to the prosthesis and configured to distribute the material from one side of the prosthesis to an opposite side that is to face the defect. The delivery device may include a manifold and conduits for delivering the material from the manifold to one or more desired locations. The conduits may penetrate into and/or through the thickness of the prosthesis. After delivery and distribution of the material, the delivery device may be removed from the prosthesis and withdrawn from) a patient.

  • Patent number: 6774460
    Abstract: The present invention relates to an impact ionisation avalanche transit time (IMPATT) diode device comprising an avalanche region and a drift region, wherein at least one narrow bandgap region, with a bandgap narrower than the bandgap in the avalanche region, is located adjacent to or within the avalanche region in order to generate within the narrow bandgap region a tunnel current which is injected into the avalanche region. This improves the predictability with which a current can be injected into the avalanche region and enables a relatively narrow pulse of current to be injected into the avalanche region in order to enable a relatively noise free avalanche multiplication. The narrow bandgap region may be located between a heavily doped contact region and the avalanche region and is preferably arranged to generate a tunnel current at the peak reverse bias applied to the diode.

  • Patent number: 6545340
    Abstract: A semiconductor device of the invention in the form of a superlattice-heterojunction bipolar transistor (SL-HBT) 10 incorporates a superlattice region 16 within an emitter mesa 21. The superlattice region 16 provides a non-linear response to a sufficiently high level of device current to counteract thermal runaway. This protects the device from damaging levels of current. The device 10 may be a radio-frequency SL-HBT with performance equivalent to that of a conventional heterojunction bipolar transistor. The invention may also be implemented as a semiconductor laser.

  • Patent number: 5611485
    Abstract: A method for dispensing a substance including the steps of housing the substance in a container in a substantially flowable state; establishing a path in proximity to the substance for movement of the substance from the container; and applying pressure to the substance within the container to force the substance from the container and along the path. An apparatus for dispensing a flowable substance including a container having an interior adapted to receive the flowable substance; an assembly adapted operably to be connected to the container and having a first passage through which the flowable substance is to be dispensed and communicating with the interior of the container through an opening; an assembly defining a second passage communicating with the interior of the container; and a mechanism for individually pressurizing the first and second passages to cause the flowable substance to be forced from the interior of the container through the opening and into the first passage to be dispensed.
