Abstract: A medical device for capturing one or more stone fragments includes a sheath having a proximal end and a distal end, a handle at the proximal end of the sheath, and a basket operable with the handle. The basket includes a plurality of wires that capture the stone fragments and has a collapsed configuration when the basket is positioned within the sheath and an expanded configuration when the basket is positioned beyond the distal end of the sheath. The medical device further includes an indicator that communicates to an operator of the medical device that the size of the stone fragments exceeds a predetermined limit and a release mechanism that releases the stone fragments from the plurality of wires when the size of the stone fragments exceeds the predetermined limit. The plurality of wires are able to reset into an operable position after releasing the stone fragments.

Abstract: Sterilizable electronic video cameras for an endoscope are provided. The electronic video camera comprises an enclosure, a lens cell, a lens cell holder, an image sensor, a motorized focusing system, and switch control. The enclosure comprises a housing and a cover, the housing defining a cavity therein. The cover has a window disposed therein, the housing and cover adapted for hermetic coupling. The lens cell is slidably disposed in the lens cell holder. The image sensor is in optical communication with the lens cell and window. The motorized focusing system is adapted to axially reciprocally move the lens cell relative to the lens cell holder controlled by the switch. The switch control is activated external to the enclosure and is hermetically sealed therewith. The lens cell, lens cell holder, image sensor, and the motorized focusing system, as an assembly, are coupled to the cover and disposed within the cavity.

Abstract: Hermetically sealed enclosures and constructions are disclosed for use in endoscopic systems, particularly endoscopic systems with electronic imaging and illumination systems in the enclosures. Compound optical windows are also disclosed for use in the systems. The compound optical windows may have separate panes for an imaging system and an illumination system, and contrast-reducing optical boundaries are between panes.

Abstract: Calibration apparatus is disclosed for a jet printer including a recording medium support having a support surface, and at least one nozzle that is operative to emit an ink jet toward the support surface and is movable along the support surface in a translation direction. The apparatus includes a probe positioned proximate the support surface that includes a plurality of edge portion pairs separated by different distances in a direction along the translation axis, and located at different distances along a test direction perpendicular to the translation direction and proximate the support surface. The apparatus also includes detection circuitry responsive to the probe, and calibration logic responsive to the detection circuitry and having a calibration result output.
