Claim 0:
1. A device for applying a negative pressure to a wound opening through the skin to the exterior of the body of a patient, wherein the wound further opens into an underlying internal lumen of the patient through an opening in a surrounding wall defining the lumen, the device comprising:
an insertion tube for being inserted into the wound through the opening of the wound in the skin;
a flexible porous element for being inserted into the wound such that the porous element is pressed against the wound around the insertion tube for application of the negative pressure to the wound in use via a peripheral outer face of the porous element between opposite proximal and distal ends of the porous element; and
a suction tube for being connected to a suction source externally of the patient's body and which is in fluid communication with the porous element to apply the negative pressure to the porous element with operation of the suction source, the porous element being mounted on the insertion tube and the insertion tube being for extending from the porous element to protrude externally from the wound opening in the skin;
wherein the insertion tube is for extending from the wound into the internal lumen when the insertion tube is located in position in the wound, the insertion tube comprising a balloon for being inflated in the lumen to anchor the insertion tube in position in the wound, and the balloon being mounted on the insertion tube forwardly of the porous element.
