    Abstract: A power plant configured for converting thermal energy to electricity includes a source of thermal energy provided by a temperature difference between a primary fluid having a first temperature and a secondary fluid having a second temperature that is different from the first temperature. The plant also includes a collector configured for enhancing the temperature difference between the primary and secondary fluids, and a heat engine configured for converting at least some thermal energy to mechanical energy. The heat engine includes a pseudoplastically pre-strained shape-memory alloy disposed in heat exchange relationship with each of the primary and secondary fluids. Further, the plant includes a generator driven by the heat engine and configured for converting mechanical energy to electricity. A method of utilizing a naturally-occurring temperature difference between air and/or water to change a crystallographic phase of the shape-memory alloy to convert the temperature difference into mechanical energy is disclosed.

    Abstract: A RF catheter system includes a catheter with a proximal portion, a distal portion having a distal end and a lumen extending from the proximal portion to the distal portion. Inner and outer coaxially aligned conductors extend within the catheter and are coaxial with the lumen. A deflectable catheter guide is disposed within the catheter lumen and extends proximally within the catheter lumen and terminates distally of the distal end of the catheter to define a biological ablation pathway. A radio-frequency antenna is disposed at the distal portion of the catheter and is in electrical communication with the inner and outer coaxially aligned conductors. The radio-frequency antenna is adaptable to receive and transmit radio-frequency energy for ablating biological tissue along the ablation pathway.

    Abstract: A catheter comprises a flexible shaft having a length for accessing the renal artery and a multiplicity of electrode sets each supported a support member. Each electrode set extends beyond the catheter's distal end and includes several elongated resilient members comprising a pre-formed curve and supporting an electrode. The resilient members are constrained to a low profile when encompassed by a wall of a removable sheath or a lumen wall of the catheter's shaft, and expand outwardly to assume a shape of their pre-formed curve when removed from the removable sheath or shaft lumen. The resilient members have a stiffness sufficient to maintain contact between the electrodes and an inner wall of the renal artery including irregularities of the inner wall of the renal artery. One or more temperature sensors can be situated at or proximate the plurality of electrode sets.

    Abstract: A drive unit for a micro valve comprises a housing, a spring and at least one shape memory alloy element which is attached to the housing in a deflectable manner. The shape memory alloy element is loaded by the spring towards a deflected position and is movable in response to a temperature increase and the shape memory effect activated thereby, into a position which is at least less deflected against an increasing load by the spring. A normally closed micro valve includes a fluid housing, at least one valve seat, a sealing element opposite the valve seat, and a drive unit of the type mentioned above. The shape memory alloy element cooperates with the sealing element and exerts an operating force on the sealing element for closing and opening the valve seat with or against a compression spring force.
