Abstract:
A valve, comprising:a flexible elongate tubular body having a proximal end and a distal end, and a lumen having a longitudinal axis extending between the proximal and distal end, the lumen having an opening at the proximal end; an expandable member on the distal end of the tubular body, the expandable member being in fluid communication with the lumen; an access opening on the tubular body, the access opening being in fluid communication with the lumen to permit the expandable member to be actuated by pressurizing the access opening; a sealing member having a sealer portion which seals against a surface of the tubular body, said portion of the sealing member being movable along the longitudinal axis relative to said surface of the tubular body between two positions, one of the positions positioning the sealer portion in contact with said surface at a location which blocks the flow of fluid to and from the expandable member through the access opening to maintain actuation of the expandable member, the other of the positions positioning the sealer portion at a location which permits the flow of fluid to and from the expandable member through the access opening to permit actuation or deactuation of the expandable member.
