A catheter for insertion into a vascular system of a patient and for directing fluid flow includes a catheter body having a longitudinal axis and longitudinally spaced proximal and distal catheter ends with an intermediate catheter portion defined therebetween. An intermediate catheter outlet in the catheter body is located in the intermediate catheter portion and is spaced longitudinally from the proximal and distal catheter ends. A first lumen is defined within the catheter body and has longitudinally spaced proximal and distal first lumen ends with a reversing bend located therebetween, the first lumen providing fluid communication between the proximal catheter end and the intermediate catheter outlet. The reversing bend is located longitudinally between the intermediate catheter outlet and the distal catheter end. The reversing bend directs fluid flow to turn approximately 180° as the fluid flows through the first lumen.

A sheath assembly for an endoscope includes an elongate tubular body and a plug. The endoscope has a handle portion and a scope portion extending therefrom to a tip. The body includes first () and second () wall sections and extends along a longitudinal axis between first and second distal openings located at distal and proximal ends thereof, respectively. The first wall section () extends radially about the longitudinal axis to define a scope lumen (). The scope portion is receivable in the scope lumen with the distal and proximal ends. The second wall section () extends radially about a portion of the first wall section () and longitudinally between second distal and proximal end openings. The first and second wall sections define an integral suction lumen () in fluid communication with a first source of negative pressure. The plug is mated with the distal end opening and includes a lens surface through which energy is transmissible.

A medical device sheath that includes a relatively inelastic body having a proximal end longitudinally separated from a distal end and defining a first lumen, an aperture located at the proximal end in fluid communication with the lumen and configured to admit an elongate endoscope body into the first lumen, and a transparent tip located longitudinally adjacent to an endoscope lens when the elongate endoscope body is located within the first lumen. The endoscope sheath may also include an elongate secondary tube defining a secondary lumen. A method of using the medical device sheath is also described.
