Abstract
A prosthesis having an apertured structure is located in a chamber (11) which is taken to sub-atmospheric pressure. Once sub-atmospheric pressure has been reached, a liquid, optionally containing pharmacological agents, is introduced into the chamber. Drawn by the sub-atmospheric pressure, the liquid saturates the apertured structure of the prosthesis. In this way, the invention eliminates the risk of air being trapped in the apertured structure that could give rise to the formation of blood clots after implantation of the prosthesis. The liquid can contain drugs that penetrate the prosthesis, performing their therapeutic action locally and over time after implantation.
