Claim 0:
1. A catheter for guiding a body fluid of a subject, comprising:
an elongated body having a proximal tip, a distal tip and further including a first portion, a second portion and a flexible portion between the first and the second portions, the first portion and the second portion are co-axial, and the second portion includes a circumferential wall defining a passageway for the body liquid, the passageway further includes an inlet and an outlet; and
an adjusting mechanism with opposing first and second ends, the first end engages the first portion and a first valve mechanism is configured at the second end, the first valve mechanism engages the second portion proximate to the inlet of the passageway, the body fluid can enter the passageway via the inlet when the first valve mechanism is retracted within the elongated body to open the passageway and the body fluid is blocked from entering the passageway when the first valve mechanism is not retracted and engages the first portion;
wherein the adjusting mechanism has a first, second and third state during use whereby in the first state the flexible portion expands to anchor the catheter inside the subject, in the second state the adjusting mechanism causes the flexible portion to contract to allow insertion or withdrawal of the catheter into/from the subject, and in a third state causes the flexible portion to expand beyond the expansion point of the first state and causes the first valve mechanism to open so the body fluid is directed to enter the passageway via the inlet of the second portion and exit via the outlet of the second portion.
