Chamber for applying therapeutic substances to an implantable device

摘要

A chamber is provided that allows a user to medicate an implantable prosthesis such as a stent. The implantable prosthesis is capable of securing a therapeutic substance and subsequently delivering the therapeutic substance to local tissues. The chamber allows a user to medicate the prosthesis subsequent to the sterilization process and immediately prior to the implantation procedure. The chamber includes a hollow body defining a chamber cavity that encapsulates the prosthesis crimped on a balloon of a catheter assembly. The chamber is removably mounted on the catheter assembly. A user can supply therapeutic substances into the chamber and allow the therapeutic substances to be secured by the prosthesis. After allowing the prosthesis to be soaked by the therapeutic substances for a predetermined amount of time, the chamber is removed and the prosthesis is ready for the implantation procedure.
