  • Publication number: 20070213591
    Abstract: A cap, which is detachably connectable to an optical head of an endoscope, has a tubular housing, which is manufactured by injection molding from translucent plastic material. The housing includes a rear open end and a frontal end closed by a frontal face and an antiglare ring for preventing a viewer of the optical head from viewing parasitic reflections. The antiglare ring is embedded within the frontal face of the cap and said optical head can view an object of interest through a portion of the frontal face which is confined by the antiglare ring. The antiglare ring is provided with at least one discontinuity region through which the plastic material can flow during injection molding of the cap.

  • Publication number: 20060252989
    Abstract: An apparatus for endoscopic examination of a body passage includes a flexible endoscope and an inflatable sleeve, which upon inflation is capable of propelling the endoscope within the body passage. The endoscope is provided with a proximal end and with a distal end, which comprises an insertion tube, a bending section and a probe. The sleeve comprises a rear folded portion and a frontal unfolded portion. The sleeve is detachably coupled with the insertion tube, wherein the rear portion of the sleeve is located behind the bending section. During the endoscopic examination the rear portion unfolds upon inflation and propels the endoscope within the body passage, while the frontal portion remains deflated and covers the bending section and the probe.

  • Publication number: 20050256376
    Abstract: A connector is described, which is suitable for establishing flow communication between passages of a multilumen tubing used with an endoscopic apparatus and between tubes for supplying fluid medium to the multilumen tubing. The connector is adapted for insertion and retraction of a surgical instrument therethrough. The connector comprises a main body portion provided with a through-going bore, which longitudinally extends along the main body portion. The main body portion further comprises a plurality of lateral ports, which are in flow communication with the through going bore. The bore is adapted for insertion thereinto and removal therefrom of a proximal end of the multilumen tubing. The lateral ports are adapted for receiving thereinto the tubes for supplying the fluid medium.

  • Patent number: 6908428
    Abstract: Apparatus for sheathing an endoscopic tool includes a sheathing assembly, which includes a sleeve dispenser and a port adapter for mating with a proximal port of an endoscopic working channel so as to permit the endoscopic tool to be advanced through the sheathing assembly into the working channel. A flexible sleeve in the sheathing assembly has a distal end, which is fixed to the sleeve dispenser, and a proximal end, which is adapted to engage the endoscopic tool as the endoscopic tool is retracted from the working channel, causing the sleeve to extend out of the dispenser in a proximal direction so as to sheath the endoscopic tool.
