摘要： An endoscopic injection needle assembly and method of using the same. According to one embodiment, the assembly includes an endoscope, an injection needle, an endoscopic hood and a suction source. The endoscope is shaped to include a proximal end, a distal end, and a plurality of longitudinal channels. The distal end of the injection needle is positioned within a working channel of the endoscope. The injection needle is sized relative to the working channel to permit fluid to flow around the injection needle in the working channel. The endoscopic hood is mounted on the distal end of the endoscope and extends distally therefrom, the endoscopic hood being in fluid communication with the working channel and having an opening through which fluid may be drawn into the endoscopic hood. The suction source is applied to the proximal end of the working channel to cause fluid to be drawn into the endoscopic hood through the opening and then proximally through the working channel. In addition, suction causes tissue to be drawn into the endoscopic hood. The injection needle may then be operated to penetrate the suctioned tissued.

摘要： Disclosed are methods and devices for removing tissue from a site in a hollow organ, where the device has a low crossing profile and is capable of removing tissue at a high rate of speed. The device includes an elongate outer tube with a side opening and an inner tube moveably coaxially positioned within the outer tube. Tissue drawn into the side opening can be severed by moving the inner tube across the opening. Tissue may be removed through the device at a rate of at least about 1.4 cc per minute, through a lumen having a cross-sectional area of no greater than about 12.02 mm. Cutting may be accomplished by rotating the inner tube at a speed of at least about 4000 rpm, and axially reciprocating the inner tube at a rate of at least about 1.5 cycles per second. The window may have a rho value of no more than about 1, and the outside diameter of the device may be no more than about 3 mm.

摘要： An apparatus and method for ejecting fluid from a fluid delivery system. The fluid delivery system has a pneumatic assembly that when triggered injects gas into a hydraulic assembly, which in turn ejects fluid through an external interface. An electronic interface displays various measurements, for example, how much fluid has been ejected and if the hydraulic system is closed the pressure of the system. The pneumatic assembly can also be depressurized such that fluid can reenter the hydraulic assembly through the external interface.

摘要： Disclosed is a tissue removal device having an outer tube with a resection window and an inner tube disposed within the outer tube. The inner tube is slidable and rotatable relative to the outer tube so that the distal end of the inner tube moves back and forth across the resection window to sever tissue extending therethrough. The inner tube may be driven to rotate at a speed of at least about 1100 rpm, to axially translate at a rate of at least about 1.5 cps, and with an advance ratio of no more than about 0.25. The drive system for controlling axial reciprocation and rotation of the inner tube may be totally mechanical.

摘要： Optical assemblies for use in medical or other devices so as to image an object under examination onto an image sensor include a plurality of lens elements that can be retained in lens barrel. The lens elements and the lens barrel can be sealed with a compressible gasket. In one example, at least one lens element is made of an injection-moldable plastic and at least one lens element is made of a relatively dispersive optical glass. A lens barrel diameter or lens diameter can be selected to permit access to the object under examination with surgical or other tools. Aperture plates can be situated so as to reduce flare in the object image.
