Robotic tool with wristed monopolar electrosurgical end effectors
ActiveUS20060079884A1Improve mobilityKeep the lengthDiagnosticsSurgical instrument detailsElectrical conductorEngineering
A surgical instrument for use with a robotic surgical system is described. The instrument includes an elongate shaft having a proximal end and a distal end. An electrically live wrist member is disposed at the distal end of the shaft. An electrocautery end effector is mounted to the wrist member. An interface is disposed at the proximal end of the shaft. The interface is removably connectable to the robotic surgical system. A conductor extends from the interface to the end effector so as to deliver electrical energy to tissue engaged by the end effector. A tip cover is disposed over the wrist member so that electrical current can only be conducted to tissues through the exposed end effector (e.g., to promote blood coagulation during usage) and not to other parts of the patient's body.

Tubular stent with oval struts
InactiveUS7153322B2Enhance crimping and symmetric expansion of stentLength of tubeStentsBlood vesselsLongest DiameterEndoluminal stent
A vascular or endoluminal stent is adapted for deployment in a vessel or tract of a patient to maintain an open lumen. The stent constitutes a scaffold formed from a single open-ended tube having a multiplicity of through-holes in its wall. The through-holes are defined by a plurality of struts that bound the holes. Each of the struts has an optimized cross-section of oval shape with a long diameter generally aligned with the length or circumference of the tube wall and a short diameter generally aligned with the thickness of the tube wall. The oval shape of the struts provide several advantages including enhancing flexibility of the stent, easing advancement of the stent through a lumen of the vessel or tract for deployment at a target site therein, protecting the balloon of a balloon catheter on which the stent is tightly crimped, and enhancing expansion of the stent during deployment while maintaining its capability to withstand compression in response to recoil of the vessel or tract following deployment.

The present invention relates to an improvement in an exhaust system structure for a motorcycle. A motorcycle has an engine disposed between front and rear wheels, an exhaust pipe extending from the engine, and a silencer connected to the exhaust pipe for discharging exhaust gases. The silencer, which is a heavy object, is of the type having a gas outlet disposed near a gas inlet. The silencer is disposed below the engine with the gas inlet facing toward the rear wheel, and the exhaust pipe extends to a position near the rear wheel and is connected to the gas inlet of the silencer. By elongating the length of the exhaust pipe and placing the silencer under the engine, the exhaust system performs sufficiently with high output engines, while at the same time lowers the center of gravity of a motorcycle body and balances the weight of the motorcycle body in its longitudinal direction.

Multiplexer hardware and software for control of a deformable mirror
InactiveUS7013183B1Low costReduce power consumptionMirrorsPiezoelectric/electrostriction/magnetostriction machinesPower modeElectricity
A multiplexer (MUX) driver system controls a deformable mirror, in part, by enabling and disabling individual or multiple actuators, mechanically coupled to the deformable mirror, through use of switches (e.g., solid-state switches) electrically coupled between the actuators and a reference node. In operation, the driver system enables actuator(s) by closing respective switch(es) and driving the enabled actuator(s) to deform respective portions of the deformable mirror in a controlled manner. The driver system disables the actuator(s) by opening the respective switch(es) to decouple the actuator(s) from the reference node. The switches, in the open state, prevent respective actuators from discharging, thereby allowing a desired surface figure of the deformable mirror to be maintained for long periods of time without having to refresh the actuators. The multiplexer driver system supports low-power modes of operation and is well suited for driving a deformable mirror in larger systems, such as space-based telescopes.
