Abstract: An apparatus for moving an elongate rod longitudinally and rotationally, and a method of moving the elongate rod longitudinally and rotationally, are provided. A translation member has a first translation member end held relatively stationary and a longitudinally spaced second translation member end which is selectively movable longitudinally with respect to the first translation member end via actuation of the translation member. The second translation member end is operatively connected to selectively impart longitudinal motion to the elongate rod. A rotation member has a first rotation member end held relatively stationary and a longitudinally spaced second rotation member end which is selectively rotatable with respect to the first rotation member end via actuation of the rotation member. The second rotation member end is operatively connected to selectively impart rotational motion to the elongate rod.

Abstract: A system and apparatus for performing transforaminal therapy utilizes a cannula positioned in the foramen ovale and a probe that is operable through an actuator to access the brain via the cannula. According to one aspect, the actuator can be a manual mechanical actuator. According to another aspect, the actuator can be a robotic actuator. According to a further aspect, the actuator can be adapted for use in an imaging environment, such as a magnetic resonance imaging (MRI) system.

Abstract: The present invention is a distributed piston elastomeric accumulator which stores energy when its elastomeric member stretches from its original length in response to the flow of a pressurized fluid. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid as its elastomeric member returns to its original length and moves the piston to its initial position. At least one part of the novelty of the invention is that the accumulator is not subject to radial strain gradients and the accumulator allows for precise pressure and linear position measurements. Accordingly, the invention allows for optimization of the energy strain storage capacity of a given elastomer.

Abstract: Described are pumps structured for moving fluids with pulsatile flow. The pumps lack valves and pistons and provide pulsatile flow through the gentle rotation of a single, one-piece, sliding vane. The vane is situated inside a slot of a rotary cylinder positioned in a hollow central opening of a housing. Generally, the vane makes minimal contact with the walls of the housing. A gap positioned between the vane and the walls and provides pulsatile fluid movement through the pump with low shear stress on the fluid. Also described are fluidic systems connected to the pumps and methods of operating the pumps and systems.

Abstract: The invention is a combination accumulator and reservoir which stores energy when the accumulator deforms from its original shape in response to the flow of a pressurized fluid from the reservoir. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid and returns to its original shape. At least one part of the novelty of the invention is that the accumulator and the fluid reservoir reside in the same housing such that the volume of each varies inversely. Accordingly, the invention is more compact and weighs less than conventional accumulators. Another feature of the invention is that fluid is located around the bladder accumulator to lubricate contact between the bladder and sides of the reservoir.
Abstract translation: 本发明是一种组合蓄能器和贮存器，其在储存器响应于来自贮存器的加压流体的流动而从其初始形状变形时储存能量。 当流体流动反向并且蓄能器排放流体并返回到其原始形状时，储存的能量返回。 本发明的新颖性的至少一部分是蓄能器和流体储存器位于相同的壳体中，使得每个容积的体积相反地变化。 因此，本发明更紧凑，重量小于常规蓄能器。 本发明的另一个特征是流体位于气囊蓄积器周围以润滑气囊和储液器侧面之间的接触。
