Abstract
A cleaning catheter includes an inflatable element and an input module, which includes an inflation chamber coupled in fluid communication with the inflatable element. A flow regulator defines a suction port coupleable in fluid communication with a suction source. A mechanical suction-control button is configured to assume at least first and second spatial positions. A mechanical inflation-control button is configured to mechanically and non-electrically increase pressure in the interior of the inflation chamber during a transition of the mechanical inflation-control button from a first spatial position to a second spatial position; and a reversibly-engageable linking element, which is moveable with respect to the mechanical suction-control button and the mechanical inflation-control button, and is configured to assume at least a first spatial position, in which the linking element does not engage the mechanical suction-control button when the mechanical suction-control button is in its second spatial position; and a second spatial position.
