Abstract: The present invention reduces pain and improves function long-term in persons with back pain using electrical stimulation in the back. This approach involves an electrical stimulation device including at least one electrode adapted for insertion within an animal body with back pain and at least one pulse generator operatively coupled with the at least one electrode, wherein the pulse generator delivers electrical stimulation activating at least a nerve innervating at least a paraspinal muscle in a back of the animal body for pain relief.

Abstract: Systems and methods are provided for treating chronic pain occurring secondarily to subacromial impingement syndrome in a human body. A system is provided to deliver percutaneous electrical stimulation through at least one electrode to neurological motor points of the posterior and middle deltoid muscles to mediate such pain. One-time, continued and/or periodic dosing of treatment methods according to the present invention may result in a change to central nervous system maladaptive neuroplasticity.

Abstract: A system and a method include a tool having an operative portion. The tool is disposed in relation to a first side of one or more components. An anvil is disposed in relation to a second side of the one or more components. The second side is opposite from the first side. The anvil includes a first portion separated from a second portion by a gap. A fluid circuit includes a fluid stream that extends through the gap. The fluid circuit is configured to remove foreign object debris generated in relation to the second side of the one or more components.

Abstract: A tissue culture chamber is disclosed. The chamber is a casing that provides for growth of three-dimensional tissue, and more specifically for the growth of skin tissue, that can be grown, preserved in frozen form, and shipped to the end user in the same aseptic container. The tissue culture chamber includes a casing comprising a substrate within the casing designed to facilitate three-dimensional tissue growth on the surface of the substrate. The casing includes an inlet and an outlet port which assist the inflow and outflow of media. The casing also includes at least one flow distributor. In one embodiment, the flow distributor is a baffle, which is used to distribute the flow of the media within the chamber to create a continuous, uniform piece of three-dimensional tissue. In a second embodiment, the flow distributor is a combination of deflector plates, distribution channels, and a flow channel.

Abstract: A sensing device which is suitable for use as a decelerometer comprises a magnetic field producing element and a Hall effect sensor element with one of the elements supported for movement relative to the other. The arrangement is such that when the device undergoes acceleration or deceleration the support allows relative movement between the elements so that the sensor element produces an output indicative of the change in field the sensor element detects from the field producing element due to the relative movement between the elements to thereby provide an indication of acceleration or deceleration of the device. The output of the sensor is connected to a differential amplifier, and the output of the amplifier is connected to a transistor in parallel with a capacitor. When the device undergoes deceleration, the output signal of the sensor increases, causing the output voltage of the differential amplifier to decrease, which in turn causes the voltage across the capacitor to discharge.
