Patent ID: 8112857

Claim:
A system for crimping a prosthesis comprising: a plurality of wheels, wherein: each wheel is rotatably mounted on an axle; each wheel has an outer circumferential surface configured to apply a radially inward force on the prosthesis; the wheels are mounted so as to be positionable in relation to each other such that a diameter of each wheel radiates outwardly from a central axis, wherein the outer circumferential surfaces of the wheels are positionable equidistant from the axis by a first smallest possible distance to define a first space that includes the axis; and a first number out of the plurality of wheels are mounted so as to be restrained from further advancing toward the axis, thereby leaving a number of remaining wheels mounted to be capable of further advancing toward the axis, wherein the outer circumferential surfaces of the remaining wheels are positionable equidistant from the axis by a second smallest possible distance to define a second space that includes the axis, the second space being smaller than the first space.
