Abstract: A pump includes a cylinder, a piston and a controller. The cylinder has first and second ends and includes first and second inlet-outlet ports, each of the first and second inlet-outlet ports is configured to alternately intake a fluid to the cylinder and output the fluid from the cylinder. The piston is configured to be moved within the cylinder between the first and second ends by alternately reversing a direction of movement of the piston, so as to pump the fluid through the first and second inlet-outlet ports. The controller is configured to control the movement of the piston within the cylinder, including: (a) choosing between first and second operational modes, (b) in the first operational mode, controlling the piston to oscillate over a predefined interval that does not exceed a predefined distance from the first end or from the second end, and (c) in the second operational mode, controlling the piston to move at a selected speed between the first end and the second end.

Abstract: A registration device, including a wand, a light guide passing through the wand, and a position sensor fixed to the wand. A light source outputs a modulated beam of light into a light guide proximal end, so that the light is emitted from a light guide distal end toward a surface in proximity to a wand distal tip. A detector receives, from the light guide proximal end, light reflected from the surface into the light guide distal end, and outputs a signal indicative of the reflected light intensity. A processor computes a distance from the distal tip of the wand to the surface by extracting a phase difference between the output beam and the reflected light from the signal, and computes a position of the surface in a sensor frame of reference responsively to the computed distance and the location of the distal tip found from the position sensor.

Abstract: An apparatus includes a relay and sampling unit, a pacing unit, a pacing detection circuit, and a processor. The relay and sampling unit receives multiple electrocardiogram (ECG) signals that are sensed by respective electrodes in a heart of a patient, and digitize a first subset of the ECG signals, and forward a second subset of the ECG signals un-digitized over analog lines. The pacing unit outputs pacing signals, which the pacing detection circuit detects and outputs a trigger in response. The processor receives the trigger and identities of ones of the electrodes via which the pacing signals are to be applied, and, in response to identifying that the electrodes, via which the pacing signals are to be applied, are currently associated with the digitized ECG signals, instructs the relay and sampling unit to switch the identified electrodes to the analog lines for transferring the pacing signals.

Abstract: A sinuplasty tool, consisting of a handle, and a rigid tube, containing a rigid tube lumen, having a rigid tube distal end and a rigid tube proximal end connected to the handle. The tool also has a resilient tube, containing a resilient tube lumen, having a resilient tube distal end and a resilient tube proximal end fixed to the rigid tube distal end so that the lumens align. The resilient tube has a multiplicity of separated openings partially encircling the resilient tube so as to form ribs in the resilient tube and permitting the resilient tube to bend. The resilient tube distal end may be inserted into a sinus of a living subject. The tool also has a wire, traversing the aligned lumens, connected to the resilient tube distal end and coupled to the handle, so that applying tension to the wire causes the resilient tube to bend.
