Abstract
Sterilization methods for implantable prostheses are described, where a polymeric stent may be sterilized, e.g., via ETO sterilization, at a temperature below a glass transition temperature of the stent. A separate delivery catheter may be sterilized separately and the stent and delivery catheter may then be combined in an aseptic, or semi-aseptic environment and sterilized as an assembled system such that the requirements for sterilizing the system are relatively lower. Additionally and/or alternatively, valve and filter assemblies may be used with an optional mandrel assembly for maintaining sterility of the internal components of a catheter system.
Claims13
A method for sterilizing a catheter assembly, comprising:
- providing a catheter having a proximal end, a distal end, and at least one lumen therethrough;
- sealing the proximal end of the at least one lumen;
- sealing the distal end of the at least one lumen via an elongate mandrel which is removably inserted into the distal end of the at least one lumen such that the lumen is isolated from an environment;
- sterilizing an interior of the at least one lumen;
- and,
- sterilizing an exterior of the catheter.
