1. A system for providing reduced pressure treatment to a wound bed that includes a fistula, the system comprising:
- a fistula-isolating device for isolating a fistula in the wound bed undergoing reduced-pressure treatment, the fistula-isolating device comprising;
an adjustable passageway member, wherein the adjustable passageway member is configured to move between a retracted position and an extended position and is substantially fluid impermeable, anda perimeter member comprising a fluid permeable material, the perimeter member positioned substantially around an exterior perimeter of the adjustable passageway member;
a distribution manifold having a fistula aperture for receiving the fistula-isolating device;
a sealing member for covering the fistula-isolating device and the distribution manifold to create a sealed space over at least a portion of the wound bed, wherein the sealing member has an ostomy-interface aperture;
a reduced-pressure source for supplying a reduced pressure to the sealed space; and
an ostomy appliance configured to be in fluid communication with the adjustable passageway member.

Abstract
Systems, methods, and devices are disclosed that involve a fistula-isolating device for use when reduced pressure is applied to a wound bed having a fistula. In one instance, the fistula-isolating device includes an adjustable passageway member and a perimeter member that contracts under reduced pressure and that automatically accommodates wound beds of different heights. In another instance, the fistula-isolating device involves a body shaped as a frustro-conical body that is readily sized for different depth wound beds. Other systems, methods, and devices are presented.
