Abstract

A reduced pressure treatment appliance is provided for enclosing and providing reduced pressure treatment to a portion of a body of a patient. The reduced pressure treatment appliance may be used to treat wounds and other conditions, such as lymphedema, varicose veins, venous insufficiency and stasis, and other infirmities. In some embodiments, the appliance includes an enclosure that encloses the portion of the body to be treated for purposes of applying a reduced pressure to the enclosed portion of the body. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the portion of the body to be treated in the volume under the enclosure. Finally, methods are provided for using various embodiments of the treatment appliance.

a one-piece enclosure comprising a flexible material and having an opening and an enclosed volume opposite the opening, wherein the enclosure is sized to be placed over and completely enclose an extremital body portion to be treated and adapted to maintain reduced pressure in the volume under the enclosure at the extremital body portion to be treated, wherein at least a portion of the enclosure is configured to deform to substantially conform to a majority of the contours of the extremital body portion to be treated when reduced pressure is present under the enclosure, wherein the extremital body portion to be treated is selected from the group consisting of a hand, a foot, a finger and a toe, and wherein the enclosure comprises a plurality of preformed channels via which fluid from the portion of the body to be treated is removed;
wound contacting material configured to be positioned primarily at the wound within the enclosure to provide a desired effect on wound tissue, wherein the wound contacting material is separate from the enclosure;
sealing means to seal the opening to the extremital body portion, wherein the sealing means is configured to maintain reduced pressure in the volume under the enclosure at the extremital body portion to be treated;
and
reduced pressure supply means to operably connect the enclosure to a reduced pressure supply source that provides a supply of reduced pressure to the enclosure, so that the volume under the enclosure at the extremital body portion to be treated is supplied with reduced pressure by the reduced pressure supply source, the reduced pressure supply means configured to supply reduced pressure to the enclosure in an amount sufficient to treat the wound.
