Abstract
Abstract A prosthetic device is packaged for surgical use by detachably coupling a support to the device, cleaning substantially all of the foreign material from the device, and encapsulating the thusly cleaned device in an openable capsule with the support extending therethrough. The encapsulated device and support attached thereto are further encased in a bag or other like protective device and this packaged assembly is further encased in a box. Sterilization of the whole is effected by means of radiation. In use, the bagged device is subsequently removed from the box and delivered to an operating room or other antiseptic environment whereat the bag is removed and the device handled by means of the support attached thereto. A solution containing, for example, heparin and an antibiotic is injected into the capsule for treating the prosthetic device. Afterwards, the capsule is opened and the prosthetic device is juxtaposed to an installation zone by means of the support.
