The endoscope comprises an inner channel comprising a primary working channel, lens system, and light delivery system and an outer secondary working channel comprising an examination field cleaning system. The inner channel is approximately cylindrical and is encompassed by a rigid or flexible tube. The outer secondary working channel is encompassed by an outer cylinder that is concentric with and fully encompasses the inner channel and tube, wherein the examination field cleaning system may comprise one or more fluid delivery channels. The endoscope may further comprise an anchoring bridge, wherein the anchoring bridge secures the outer cylinder to the inner channel.

    摘要: A multi-!umen catheter assembly comprises an inner shaft, an outer shaft and one or more features. The inner shaft comprises an inner surface and an outer surface. The inner surface defines a first lumen. The outer shaft is coaxially disposed about the inner shaft and is deformabie inwardly toward the outer surface of the inner shaft. The outer shaft comprises an inner surface and an outer surface. The outer shaft is radially space from the inner shaft such that the inner surface of the outer shaft and the outer surface of the inner shaft together define a second lumen. The one or more features are configured to maintain patency through the second lumen as the outer shaft deforms inwardly toward the outer surface of the inner shaft.

    摘要: A catheter tube for insertion into a body of a patient is disclosed. The catheter tube includes a distal portion that remains stable during fluid infusion into the patient, thus reducing or eliminating whipping of the catheter distal tip, even during power injection. In one embodiment, the catheter tube defines at least one lumen and is formed from a tube material that defines a proximal portion and a distal portion of the catheter tube. The catheter tube is configured such that the arithmetic product of an elastic modulus and an area moment of inertia for at least a portion of the distal portion of the catheter tube defined by the catheter tube material is greater relative the arithmetic product of an elastic modulus and an area moment of inertia for at least a portion of the proximal portion of the catheter tube.
