Abstract
A catheter is provided having a main body defining two lumens and a connection structure at a proximal end of the main body. This structure includes a housing attached directly to the main body and defining a pair of passages connecting one to each of the lumens, and a pair of rotary valves operable to open and close the passages. The rotary valves are operable manually about individual axes by operators attached to the valves to turn the valves. The operators may be ganged for movement together to move both valves simultaneously between open and closed positions.
