Abstract: A medical instrument comprises a shaft, a work element at the distal end of the shaft, a handle with at least one movable part for actuating the work element and a securing element for securing an endoscope which has an endoscope shaft and an eyepiece. The distal end of the endoscope is able to be arranged in the area of the distal end of the shaft, and the proximal end of the endoscope is able to be arranged in the area of the handle of the instrument, and the endoscope is displaceable in the longitudinal direction of the shaft. The securing element is designed in such a way that the endoscope can be arranged on the outside of the instrument, the eyepiece of the endoscope, in the state when the latter is arranged on the instrument, lying outside the longitudinal axis of the shaft of the instrument.

Abstract: A balloon catheter has an elongated flexible shaft made of a metal and at least one inflatable balloon mounted on a distal end area of the flexible shaft. A wall of the shaft providing the mechanical properties for flexibility and pushability is entirely made of metal, the wall has a sheet-like shape, and the wall has an outer diameter up to 0.5 mm and a wall thickness in a range from 0.02 mm to 0.1 mm.

Abstract: The description relates to a medical and especially an endoscopic instrument having a manipulator with a guide channel on which are arranged at least one drive and at least one guide wheel or roller the peripheral surface of which can be engaged with the outer contour of an instrument part in such a way that this instrument part can be moved to and from along its longitudinal axis in relation to the manipulator. The instrument of the invention is distinguished in that, to fit different outside diameters of the instrument part to be moved, at least one of the wheels can be moved at least in the direction perpendicular to the guide channel and/or at least one of the wheels has an elastic coating on its outer periphery.
