A medical manipulator includes a wire movable in opposite directions, a driven wire having both ends thereof connected to the wire, an end effector of a distal-end working unit, a transmitting member, a crescent driven member integral with the transmitting member, and a return pulley. The transmitting member, the crescent driven member, and the return pulley are successively arranged in this order from the proximal end of the medical manipulator. When the driven wire is moved in opposite directions, the transmitting member also moves in opposite directions. At this time, the crescent driven member moves toward the return pulley, and the proximal-end portion of the return pulley enters a cavity of the crescent driven member.

An apparatus and method for mastopexy surgeries correcting a ptosis condition caused by tissue stretching, in the breast as a result of pregnancy, time, aging, and the effects of gravity and athletic activity provide an implant having homogeneously formed connectors extending from inside an implant wall for anchoring to the chest wall or chest muscles of a patient. Embedded reinforcements and anchoring tabs or sutures may be readily oriented along a rib or other defining physiological location in order to provide immediate, permanent, and symmetric installation of implants in a mastopexy reconstruction.

An implantable neurostimulator system for treating movement disorders includes a sensor, a detection subsystem capable of identifying episodes of a movement disorder by analyzing a signal received from the sensor, and a therapy subsystem capable of applying therapeutic electrical stimulation to treat the movement disorder. The system treats movement disorders by detecting physiological conditions characteristic of an episode of symptoms of the movement disorder and selectively initiating therapy when such conditions are detected.

A thermoelectric semiconductor module (10) includes a plurality of semiconductor pellets (14, 18) having Peltier characteristics are mechanically interconnected and arranged in an electrical series circuit with heat transferring means (12, 16, 20) with all interconnections being directly made. The means (12, 16, 20) can be of platelike construction with an L-shaped cross-section or, alternatively, with a U-shaped cross-section. A large number of modules (10) can be arranged in a two-dimensional or three-dimensional stack (30) with adjacent lines or planes of modules electrically interrelated by end segment connectors (32). In a further version, one side of a modular plane has heat exchanger fins (44-50) while the other side is electrically connected by ceramic segments (58) with deposited conductors (56). In yet another version, the modules are mounted onto rotating discs (94, 96) so as to act as a fluid impeller moving therepast enhancing thermal efficiency.

A method for manufacturing a conducting polymer composite with carbon nanotubes is described. A conducting polymer is compounded with the CNT film by in-situ electrochemical polymerization.

The present invention provides a composite structure having a supporting substrate between a piezoelectric substrate and a compensation layer. The materials used to form the piezoelectric substrate and the compensation layer in isolation, have higher thermal coefficients of expansion (TCE) relative to the TCE of the materials forming the supporting substrate. Once the composite structure is created, the piezoelectric substrate and compensation layer tend to expand and contract in a similar manner as temperature changes. The expansion and contraction forces applied to the supporting substrate by the piezoelectric substrate due to temperature changes are substantially countered by similar opposing forces applied by the compensation layer, resulting in the opposing forces substantially counteracting one another. Due to the counteraction, the composite structure resists bending or warping, reducing expansion and contraction and increasing stress of the piezoelectric substrate, and thus reducing the effective TCE and TCF of the piezoelectric substrate.

A carbon nanotube-conductive polymer composite includes a plurality of CNTs and conductive polymer fibers. The CNTs are connected with each other to form a network. The conductive polymer fibers adhere to surfaces of the CNTs and / or tube walls of the CNTs.
