Claim 19:
20. A pinch valve comprising:
a housing having a lumen therein between a first opening and a second opening;
a deformable member positioned within the housing along the lumen, wherein the deformable member is movable between a first position having a first internal diameter and a second position having a second internal diameter that is smaller than the first internal diameter;
a containment sleeve positioned radially outward from the deformable member, wherein the containment sleeve is movable between a first containment sleeve position having a first containment sleeve internal diameter and a second containment sleeve position having a second containment sleeve internal diameter that is smaller than the first containment sleeve internal diameter; and
a fluid channel configured to selectively introduce fluid pressure from a fluid pressure source into a cavity formed between the housing and the containment sleeve to cause the containment sleeve to move from the first containment sleeve position to the second containment sleeve position which causes the deformable member to move from the first position to the second position.
