Abstract
A radial compression mechanism includes a constraining structure with a cut-out defined by a plurality of bearing surfaces. A plurality of die are carried by the constraining structure and arranged in a circular pattern about a central axis. Each die has a base side positioned in parallel juxtaposition to a corresponding bearing surface and each die is constrained to move reciprocally and linearly along the corresponding bearing surface. Working surfaces of the plurality of die cooperate to form a cavity that is movable between an open position and a closed position. A driving mechanism is coupled to at least one of the plurality of die to drive all of the die in unison between the open position and the closed position.
