Devices and methods for treatment of fistulas and complex wounds

摘要

An enteric fistula healing device, configured for application over a fistula or other wound to physically separate the fistula from the remainder of the wound area, such that any effluent from the intestine or bowel, or other enteric substances, that pass through the fistula are prevented from communicating with the wound area. The device is configured to collapse from a first height to a shorter second height.

主权项

1. A device to manage effluent drainage from a wound such as a fistula, the wound including a wound opening, and a wound bed surrounding the wound opening, the device comprising:
a liquid containment vessel having a first end and an interior volume defined by a sidewall configured to collapse from a first height to a second height less than the first height, the liquid containment vessel having an outer diameter at the first end, the first end defining a primary vessel opening providing liquid communication between the interior volume and the wound opening; a flexible and trimmable annular skirt depending from the first end of the vessel; and a wound sealing flange proximate the primary vessel opening, the flange having an outer diameter greater than the vessel outer diameter at the first end, wherein the device is configured to be applied to the wound bed such that the sidewall and the skirt surround the wound opening, the skirt at least partially extending around or within the wound opening, and the flange forms a seal around the wound opening, thereby physically isolating the wound opening from the wound bed.
