Claim 14:
15. A method for treating a wound about an insertion tube passing through the wound into an underlying internal lumen of the patient, the wound opening to exterior of the body of the patient through the skin of the patient, and the method comprising:
locating a flexible porous element mounted on the insertion tube into the wound whereby the insertion tube protrudes externally from the wound opening in the skin and extends from the wound into the lumen through an opening in a surrounding wall defining the lumen, and the porous element has a peripheral outer face defined between opposite proximal and distal ends of the porous element, the porous element being in fluid communication with a suction source externally of the patient's body for application of a negative pressure to the wound around the insertion tube via the peripheral outer face of the porous element with operation of the suction source, and wherein the insertion tube comprises a balloon for being inflated in the lumen to anchor the insertion tube in position in the wound, and the balloon is located on the insertion tube forwardly of the porous element;
inflating the balloon in the lumen to anchor the insertion tube in position in the wound; and
applying the negative pressure to the wound via the peripheral outer face of the porous element.
