Abstract: A system and method for treatment of diabetic peripheral neuropathy is illustrated and described. The system is a portable massage system for application with the feet. The system includes a frame to resist flexure and configured to hold a rod assembly. The rod assembly is elevated by the frame and configured to rotate upon the application of a tangential force to a surface of the rod assembly. The rod assembly includes a rod having two ends. Each end of the rod is inserted into a portion of the frame. Additionally, the assembly includes a grip configured to surround a portion of the rod and used to increase friction upon contact. Rotation of the rod assembly selectively applies pressure to stimulate blood flow.

Abstract: A bridge plug arrangement includes a plug having an upper end and a bottom end. The bridge plug arrangement also optionally includes a cylindrical seat. The bridge plug arrangement further includes a tubular member. The tubular member may be part of a casing string. The tubular member is configured to receive the plug and, when used, the seat. The plug and/or the seat may be fabricated from a frangible material. Also disclosed is a method for diverting fluids in a wellbore using the bridge plug arrangement. The method may include landing the plug onto the seat within the wellbore below a subsurface zone of interest. Treatment fluids are then injected into the wellbore, where they are diverted through perforations and into a formation. The plug and/or seat is then optionally broken into a plurality of pieces through use of a downward mechanical force.

Abstract: A low swage load fastening system is provided for installing swage-type fasteners to secure a plurality of workpieces together. The fastener includes a pin member having an elongated pin shank to be located in aligned openings in the workpieces. An enlarged head at one end of the pin engages one side of the workpieces. A grooved pin portion extends past an opposite side of the workpieces. A collar includes a shank portion adapted to be swaged into the pin lock grooves in response to a relative axial swage load applied by an installation tool. As one aspect of the system, the collar is as-headed and does not require thermal processing yet provides an optimum balance of reduced collar shank wall thickness and increased hardness, whereby the swage load is minimized. A low swage load thread form for the lock grooves of the pin is also provided, a reduced diameter, relatively short pull portion pin extension, installation tool improvements, and an associated method of use are also disclosed.

Abstract: A locking fastener that includes an elongated tubular member and a pin member. The elongated tubular member has a body with an internal diameter, a first end, and a second end, the second end having a head. The pin member has a first end, a second end and a mechanical lock portion. The pin member first end has a diameter about the same as the tubular member body internal diameter. The pin member first end further has a head, the head having a diameter larger than the tubular member body internal diameter. The mechanical lock portion is disposed between the pin member first end and the second end. The pin member is disposed in the tubular member with the pin head extending from the tubular member first end.
