摘要： Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.

摘要： A method of retrieving calculus in a living body and relocating the calculus to a different location in the living body involves positioning an elongated member in the living body in which the calculus is located, drawing the calculus in the living body toward the elongated member while the elongated member is positioned in the living body so that the calculus is retained by the elongated member; moving the elongated member so that the elongated member is located at a position in the living body that is different from the position of the elongated member in the living body during the drawing of the calculus toward the elongated member; and releasing the calculus from the elongated member so that the calculus is at a position in the living body different from a location of the calculus in the living body while the calculus is being drawn toward the elongated member.

摘要： A device for removing viscous or semi-viscous material from an individual is disclosed. The device uses suction which may be provided by a vacuum source. The device includes a tube. The tube has a proximal opening and a distal opening, and a first stop at a first lengthwise position on an inner wall of the tube. The distal opening is in pneumatic communication with the vacuum source. The device also includes an agitator rotatably disposed in the tube. The agitator has a helical blade, a first end, and a second end. The first end is configured to engage the first stop such that the agitator is rotatable about the axis of the helical blade while being at a substantially fixed position along the length of the tube.

摘要： An endoscope for removing tissue at a surgical site includes an elongated tubular body insertable within a mammalian cavity of a patient. An instrument channel extends between a first opening at a distal end and a second opening at a proximal end of the tubular body and is sized and configured to receive a surgical cutting assembly that includes an aspiration channel configured to remove material entering the endoscope via a distal end of the surgical cutting assembly. A torque generation component configured to generate torque is positioned within the distal end and configured to provide the generated torque to a coupling component. The coupling component is positioned at the distal end of the elongated tubular member and configured to actuate a cutting component of the surgical cutting assembly responsive to actuation of the torque generation component.

摘要： A reciprocating surgical file system for precisely removing bone and/or other tissue is described. The system allows a user to maneuver the system and navigate into hard-to-access sites under a direct vision mechanism. A transmission mechanism converts rotary motion from a motor into reciprocating motion and provides it to the surgical file for precision removal of bone or other tissue. A pulsatile pump mechanism is operatively coupled with the transmission mechanism and provides irrigating fluid to the surgical site.

摘要： A dental handpiece is disclosed including a turbine construction creating a radial in flow of air onto the impeller blades about the whole circumference of the turbine. An air guide inserted into the turbine housing and extending about the turbine defines a drive air supply chamber separated from the turbine housing and communicating with a drive air supply conduit. The air guide has a plurality of inlet openings for radially inwardly directing pressurized air from the drive air supply chamber into the turbine housing onto the turbine.
