The present invention relates to devices and methods for providing controlled environments for surgical procedures, as well as transplantation and wound healing. In particular, one embodiment of the present invention provides devices and methods to provide an anaerobic environment for incision sites. In other embodiments, the present invention provides devices and methods to maintain anaerobic conditions during the collection, transport, and implantation of organs, tissues, cells, and other transplant material. In further embodiments, the present invention provides devices and methods for the production and maintenance of an anaerobic environment surrounding sites of trauma or tissue injury. In particular, the present invention provides devices and methods which allow the operator to strictly control the environment for surgical procedures, transplantation and wound healing, etc. Thus, the present invention also finds use in specialized settings where hyperoxic conditions are desireable.
A device for maintaining a surgical field in an isolated environment comprising an enclosure for separating said surgical field from an atmosphere ambient to said device, a means for evacuating said isolated environment, a means for refilling said isolated environment, and at least one access port, wherein said access port enables admission into said enclosure.
A device for maintaining a surgical field in an isolated environment comprising an enclosure for separating said surgical field from an atmosphere ambient to said device, a means for filling said isolated environment, and at least one access port, wherein said means for filling produces an environment with adjusted oxygen tension and said access port enables admission into said enclosure.
A device for maintaining an injured area in an isolated environment comprising an enclosure for separating said injured area from the atmosphere ambient to said device, a means for evacuating said isolated environment, and a means for refilling said isolated environment, wherein the oxygen tension of said isolated environment is controllable.
A device for maintaining an injured area in an isolated environment comprising an enclosure for separating said injured area from the atmosphere ambient to said device, and a means for filling said isolated environment, wherein said means for filling produces an environment with adjusted oxygen tension.
A device for maintaining transplant material in an isolated environment comprising an enclosure for separating said transplant material from an atmosphere ambient to said device, a means for evacuating said isolated environment, and a means for refilling said isolated environment, wherein the oxygen tension of said isolated environment is controllable.
A device for maintaining transplant material in an isolated environment comprising an enclosure for separating said transplant material from an atmosphere ambient to said device, and a means for filling said isolated environment, wherein said means for filling produces an environment with adjusted oxygen tension.
