Abstract

See full text

A hydrogel marker is placed under stress during its curing stage, in one embodiment, by application of an externally applied force. The stress may also be induced during or after the dehydration process. The direction of the externally applied force increases the length, width, depth, or radial extent of the marker. The elastic limit of the marker is exceeded when the external force is applied so that the marker substantially retains its stressed size and shape when the externally applied force is removed. When the stretched or otherwise deformed dehydrated marker is hydrated, it substantially returns to the configuration it had prior to its dehydration and prior to the application of the externally applied force.
