Claim Text:
1. A device for applying a negative pressure to an endoluminal surface in the body of a patient to facilitate healing of a wound in the endoluminal surface, comprising: a flexible porous element with a peripheral outer face for contact with the wound, the outer face being defined between opposite proximal and distal ends of the porous element; 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 a negative pressure to the wound via the outer face of the porous element upon operation of the suction source, the porous element having at least one through passageway extending from its proximal end to its distal end for passage of bodily substances of the patient through the porous element separately from any exudate drawn from the wound into the porous element through its said outer face by the applied negative pressure, at least one of the proximal and distal ends of the porous element being otherwise sealed against egress of the bodily substances into the porous element; and a drainage tube for collection and drainage of the bodily substances from the patient, wherein the drainage tube is received in the through passageway of the porous element.
