Abstract: A method of preparing a hydrophilic plastic cartridge by centrifugally casting polymerizable hydrophilic material in a rotating polymerization tube whose longitudinal axis is maintained parallel to the ground. The speed of rotation causes radial outward displacement of the polymerizable material which upon assuming a predetermined shape within the rotating tube is then polymerized to the predetermined solid configuration. The resulting plastic cartridge is characterized by smooth, unscored internal and external cylindrical surfaces. The cartridges are used as a rate-limiting membrane in drug delivery devices. Sterilized kits containing a disposable needle/syringe or trocar-like instrument and the drug delivery device are used for subcutaneous implantation of the device in an animal body.

Title: Orthosis with distraction through range of motion
Inventor: BONUTTI PETER M
IPC: G04F5/02
Filed: 1992-04-15
Granted: 1998-07-28
Abstract: An orthosis for stretching tissue that limits compressive forces on the soft tissue around a joint during movement of the joint. The orthosis includes two relatively pivotable cuff arms with a cuff on each arm. The cuffs clamp onto the body portions on either side of the joint. The pivot axis of the cuff arms is spaced from the pivot axis of the joint, so that movement of the cuff arms to extend the joint results in distractive forces being applied to the joint. The cuffs are selectively moved on the cuff arms, during extension and flexion, to provide the proper amount of distractive forces to the joint and to limit compressive forces on the joint. A mechanical advantage is gained through the use of a gear drive mechanism for transmitting to the joint the force applied by the patient. This allows the orthosis to be relatively small and light weight. The orthosis also provides a portable system for continuous passive motion therapy for a joint. The orthosis may be operated by a manual plus electric drive cycling it between extremes of motion. Provision is made for monitoring the range of motion or the force applied.

Title: Hydraulically powered repetitive impact hammer
Inventor: OTTESTAD JACK B
IPC: B25D17/24
Filed: 1990-12-20
Granted: 1995-07-11
Abstract: A hydraulically powered repetitive impact hammer (20) has internal features for ensuring continued automatic repetitive operation under adverse conditions, and fluid cushioning of internal parts to prevent damage from abrupt metal-to-metal contact. The hammer head (31) of the impact hammer (20) has an internal poppet (55) which automatically closes to enable the buildup of pres-sure in a compression chamber during reloading in preparation for the hammer head's next blow (31), and automatically opens to enable the pressure in the compression chamber (47) to drive the hammer head (31) to strike an impact tool (25). To prevent inadvertent stalling of the hammer dur-ing reloading if the impact tool (25) is pressed forcibly into contact with the working face (30) after striking a blow, the amplification ratio of the hammer head (31) is made greater than the amplifica-tion ratio of the poppet (55). Fluid cushioning of the hammer head (31) to prevent abrupt metal-to-metal contact with the frame (21) of the hammer (31) at the end of the driving stroke is provided by a temporary fluid restriction which operates only when the hammer head (31) is near the end of its driving stroke. Fluid cushioning of the poppet (55) to prevent abrupt contact with the hammer head (31) is provided by mating fluid cushioning surfaces (195, 197) formed on the hammer head (31) and poppet (55), respectively, for enclosing fluid in a confined space as the poppet (55) approaches one or the other extremity of its range of movement in the hammer head (31).
