A medical device comprising:
- a. an elongated tubular body with a proximal control end and a distal functional end;
- b. at least one expandable element having a middle region, a distal end and a proximal end, said expandable element positioned at the distal functional end of the elongated tubular body;
- and
- c. a slidable constraint having at least two portions each surrounding at least a section of the expandable element so that upon expansion of the expandable element the at least two portions of the slidable constraint slide in opposing directions away from the middle region toward the distal end and the proximal end of the expandable element.
