  • Patent number: 10327834
    Abstract: A method for manufacturing an end effector assembly includes providing first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second, approximated position. One of the first and second jaw members includes a cavity defined therein and the other of the first and second jaw members includes a stop member configured to be inserted into the cavity. A gap-setting gauge is grasped between the first and second jaw members to define a gap-distance between the jaw members equivalent to a thickness of the gap-setting gauge. The first and second jaw members are set such that the jaw members are prevented from approximation beyond the gap-distance.

  • Patent number: 9226732
    Abstract: Devices for extracting bone marrow from a bone of a patient are disclosed. The device includes a housing defined in part by a cannula and a hollow needle disposed within the cannula. The hollow needle is movable axially relative to the cannula and extendable therefrom. The hollow needle is configured to aspirate bone marrow within a bone. A depth adjustment mechanism coupled to the hollow needle and the cannula is used to adjust the depth of the hollow needle relative to the cannula to control the distance of the needle within the bone. The device is attachable to an extraction device to extract bone marrow from the patient through the hollow needle. Methods of using these devices and methods of extracting bone marrow are also included.

  • Patent number: 8765396
    Abstract: Methods of screening a test agent for activity to modulate an oxidative demethylation enzyme are provided according to embodiments of the present invention which includes preparing a test reaction comprising an oxidative demethylation enzyme, a substrate for the oxidative demethylation enzyme, a test agent and 4-amino-3-penten-2-one under conditions which allow generation of formaldehyde by oxidative demethylation of the substrate by the enzyme in the absence of the test agent; detecting fluorescence in the test reaction, the fluorescence indicative of reaction of formaldehyde and 4-amino-3-penten-2-one in the test reaction; and comparing fluorescence detected in the test reaction with a control, wherein a difference in detected fluorescence is indicative of a change in activity of the oxidative demethylation enzyme in the presence of the test agent.

  • Patent number: 8348887
    Abstract: A container (2) receives anhydrous material to be hydrated and hydrating fluids. The hydrating fluids are introduced into the container through a fluid port (8) by one or more containers having hydrating fluid. The hydrating fluids may be a mixture of fluids provided in any desired proportion. The hydrated material is then ejected from the container.

  • Publication number: 20060243133
    Abstract: A gas generating system (S) has a plurality of product gas generating modules (18) each of which comprises a plurality of molecular sieve beds (bed 1, bed 2) generating a product gas acting in a repetitive cycle with each cycle having a period of the cycle with peak product gas flow (106). A manifold (52) combines the product gas from the plurality of modules (18). The processor (58) generates a control signal that is communicated to the gas generating modules (18) such that the peak product gas flow period (106) of the repetitive cycle of the modules (18) is adjusted in response to the control signal. The processor (58) causes the peak period (106) for the modules (18) to be timed across the repetitive cycles in a controlled distribution.

  • Publication number: 20060062707
    Abstract: An electronic controller (16) controls the operation of an electrochemical oxygen generating system (14) producing a desired gas. The product gas is fed to a storage unit (12) or a regulator (28) and pulsing valve (28) controlling the gas flow to a user. A two-stage system (180) combines a low pressure 100 and a high pressure (150) gas generating subsystems. The low pressure subsystem (100) uses IMAT's (106) to pump oxygen from ambient air to generate a low-pressure. The high pressure subsystem (150) uses IMAT's (160) to pump oxygen to high-pressure oxygen storage devices (194).

  • Patent number: 6236809
    Abstract: An intravenous fluid heater is provided that is dimensioned so as to be wearable adjacent a patient's intravenous fluid infusion situs. In one embodiment, the heater includes a heat exchanger for defining a flow path through the heater for fluid to be infused via the infusion situs. At least one controllable heating element is provided for heating the fluid in the flow path by heat conduction thereto through the heat exchanger. Sensors are included for sensing respective temperatures of entering and exiting fluids of the flow path. A controller controls, based upon the temperatures of the exiting fluids, heating of the fluid in the flow path by the heating element so as to cause the fluid in the flow path to be substantially uniformly heated to a desired infusion temperature prior to exiting the heater.
