A biocompatible, mechanical, micromachined pressure sensor and methods of manufacturing such a pressure sensor are provided. The pressure sensor of the current invention includes a high-aspect-ratio curved-tube structure fabricated through a one-layer parylene process. The pressure sensor of the current invention requires zero power consumption and indicates the pressure variation by changes of the in situ in-plane motion of the sensor, which can be gauged externally by a direct and convenient optical observation. In one embodiment, the pressure sensor of the current invention has been shown to work as an IOP sensor for eye implantation where the intraocular in-plane motion of the sensor can be recorded from outside of the eye, such that the intraocular pressure in glaucoma patients can be constantly monitored.

A cable guide and system are disclosed for maintaining a desired bend radius. The cable guide includes two substantially curved tube halves, each tube half comprising a curved portion having a predetermined radius. The cable guide also includes a hinge joining the tube halves and a fastening member configured to fasten the tube halves together. A first end of each of the tube halves is shaped to adhere to a cable connector. The cable connector terminates a cable. The tube halves have an open configuration and a closed configuration. When in the closed configuration, the tube halves are fastened together by the fastening member. In the closed configuration, the tube halves form a tubular sleeve. The tubular sleeve includes a lumen through which a cable may extend.

A stent comprises a flexible tube having a proximal end, a distal end, and a passageway extending from said proximal end toward said distal end. A first generally straight tube segment extends from the proximal end while a first generally curved segment extends from an end region of the first generally straight tube segment disposed away from the proximal end of the stent. A second generally straight tube segment extends from an end region of the first curved segment away from the first generally straight tube segment and is arranged at an acute angle relative to the first generally straight tube segment. A second generally curved tube segment extends from one end of the second generally straight tube segment and includes a channel on an exterior surface of the second generally curved tube segment. The first generally curved tube segment and the second generally straight tube segment further include at least one cavity irrigation hole extending from the tube passageway, for providing irrigation fluids into the cavity into which the stent is inserted. At least one segments includes a channel on an exterior surface. The channel is sized to serve as a reservoir to contain a predetermined amount of at least one form of medication for delivery, over a period of time, of the medication to a cavity region proximate which the stent has been inserted.

A cooling system for an annular stator housed within a transmission casing includes a first curved tube sufficiently sized to at least partially circumscribe the stator when the tube is placed within the casing. The first tube has a plurality of circumferentially spaced fluid openings. An intake conduit connects the first tube to the transmission casing to deliver fluid through the tube for flow through the fluid openings to cool the stator. Preferably, a second like curved tube is also provided and a connector tube connects the first and second tubes to allow fluid flow therebetween. A method of assembling a cooling system is also provided.

A fastening-type pipe supporting apparatus capable of supporting a curved pipe against loads acting on a curved portion of the pipe via clamps having curved surfaces and being easily attached to and detached from the curved portion of the pipe. The fastening-type pipe supporting apparatus includes: a first clamp having a semicircular cross-sectional shape and a curved surface with a curvature to surround the curved portion of a pipe; a second clamp having a semicircular cross-sectional shape and a curved surface with a curvature to surround the curved portion of the pipe, the second clamp being coupled to the first clamp; a connection bolt coupling the first clamp with the second clamp; and a washer placed around the connection bolt.

A Coriolis flow meter is disclosed that uses the deflection of a torsion member (430) to balance the vibration of a single curved flow tube (308). The two ends of the torsion member are attached to, and vibrate with, a center section of the single flow tube (308). A balance member (432) is attached to a center section of the torsion member (430) and vibrates in the opposite phase of the single flow tube (308) causing the torsion member (430) to be deflected in torsion.
