1. A crimping device including:
a housing defining a bore having an axis, which housing comprises a first part and a second part that are rotatable relative to each other about the axis; and
at least three extendable mechanisms angularly equispaced about the axis of the bore, each of which extendable mechanism including:
a first elongate arm hingedly connected at or near a first axial end of the first arm to the first part of the housing;
a second elongate arm hingedly connected at or near a first axial end of the second arm to the second part of the housing,
wherein:
the first axial ends of the first and second arms are circumaxially displaceable relative to each other;
the first and second arms are hingedly connected at or near their second axial ends to each other; and
the first and second arms are of the same length; and
means for rotating the first part of the housing relative to the second part of the housing about the axis and thereby circumaxially equi-displacing the first axial ends of coupled first and second arms relative to each other, thereby to configure the crimping device between: (i) a dilated condition in which the second axial ends of the first and second arms are maximally spaced from the bore axis; and (ii) a contracted condition in which the second axial ends of the first and second arms are minimally spaced from the bore axis.
