Abstract: An end-firing surgical laser fiber suitable for Thulium Laser Fiber lithotripsy applications includes a standoff that extends beyond the distal end surface of the fiber to prevent contact between the end face of the fiber and a targeted stone. The standoff may either (1) extend along only one side of or partially around a circumference of the fiber, so that dust from the pulverized stone can freely flow downstream from the treatment site without being trapped by or accumulating on the standoff, or (2) include at least one flushing port that prevents dust accumulation by permitting passage of dust from within the standoff. Flushing of dust from within the standoff may be facilitated by including a source of fluid to entrain the dust and carry it through the flushing port.

Abstract: A surface cleaning head includes a housing having a front side and back side, a brush roll rotatably mounted to the housing within a suction conduit and having at least a portion proximate the opening of the suction conduit, a leading roller mounted to the housing in front of the brush roll, and a drive mechanism operatively coupled to the brush roll and the leading roller for driving the brush roll and the leading roller at same time. The brush roll includes an agitator body and a first bristle/flap arrangement comprising a first deformable flap extending from the agitator body and a first bristle strip and/or row of tufts extending from the agitator body and disposed adjacent to the first deformable flap. The first deformable flap is disposed at an aggressive angle and the first bristle strip and/or row of tufts is arranged at a passive angle.

Abstract: A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

Abstract: An abatement system is provided which includes 1) an abatement unit adapted to abate effluent; and 2) an ambient air supply system. The ambient air supply system includes an air moving device, wherein the ambient air supply system is adapted to supply ambient air to the abatement unit for use as an oxidant. Numerous other aspects are provided.

Abstract: An abatement system is provided, including an abatement unit adapted to abate effluent using ambient air; and an ambient air delivery system in fluid communication with the abatement unit and adapted to deliver ambient air to the abatement unit; wherein the ambient air delivery system allows sufficient ambient air to flow into the abatement unit to abate the effluent without compressed air. Numerous other aspects are provided.

Abstract: A non-deforming deflectable multi-lumen catheter with an outer jacket having a deflectable distal end portion, an eccentric pull wire lumen, coil and shim embedded therein. The deflectable distal portion optionally having one or more transaxial notches in the external surface of the outer jacket. A functional device is disposed within the lumen of an inner tube substantially coaxial with the outer jacket of the catheter. The distal tip of the functional device egressible from the distal tip of the catheter, and upon deflection, automatically aligns with the distal tip of the catheter and functional device.

Abstract: A modular drug delivery system for use by cardiothoracic surgeons and interventional cardiologists for delivery of molecular and cellular therapies that target genes, molecules and peptides. The regulated drug delivery devices comprise a modular mechanically actuated drug delivery module (DDM) that can be attached to either a surgical viewing endoscope hand-piece or specialized catheter for interventional procedures. The DDM provides metering of drugs to treatment sites and allows for quick interchangeability with other component parts such as a viewing scope end portion for MIS or other surgical procedures or a flexible catheter shaft for percutaneous procedures.
