Abstract: A saw blade for an oscillating saw can include a plate having cutting teeth arranged in an arcuate tooth pattern at a cutting path. Cutting teeth on opposite sides of the centerline of the plate may be arranged to face oppositely. Each cutting tooth can have primary and secondary relief surfaces at different angles to the cutting path. Cutting teeth may be offset outwardly from the plate, with tips of some of the cutting teeth having outward-facing kerf surfaces parallel to the plate. The plate may be of bimetal construction, so that the cutting teeth and bulk of the plate are made of different materials. The cutting teeth may be formed by a coining process.

Abstract: Here is disclosed a reusable pneumatic distraction device having a housing which encloses a first and a second gas reservoir which are configured to contain a quantity of high and low pressure gas, respectively. A valve member seals off an exhaust in the first gas reservoir, the valve member movable between a closed position sealing the exhaust and an open position. The device also includes a pneumatic drive for urging the valve towards its opened position. The pneumatic drive configured to apply a lower urging force followed by a larger urging force as the valve opens. The device is also provided with a lock pin releasably coupled to the valve for preventing the valve from moving towards its open position. Finally, the device includes a delay mechanism to delay the opening of the piston when the lock pin is released.

Abstract: An apparatus for conditioning mammalian blood for subsequent use in a medical procedure includes a cabinet having a secure environment and a door providing the only access to the environment. An input system transports a blood charge from a source to the cabinet and a flask is removably contained in the secure environment and coupled to the charge input system to receive the charge. Stressors are coupled to the cabinet and positioned for operation to create a conditioned charge in the flask. An output system is coupled to the flask and includes a receiver for the conditioned charge. The apparatus includes an automated control system operable upon closing the door to lock the door and to then condition the charge, and to then cause the charge to move from the flask to the receiver.
