Abstract
Aspects of the disclosure relate to “wet” transcatheter prosthetic heart valve or other implant packaging and assemblies in which a prosthetic heart valve or other implant is loaded into a first portion of a delivery device and positioned within a container in which sterilizing fluid is retained to sterilize inside of the container as well as provide moisture to prevent the implant from drying out. The disclosure also relates to methods of sterilizing the disclosed assemblies. Some disclosed methods include at least two sterilizing steps and adjustment of a shaft seal or formation of multiple seals maintaining sterilizing fluid within the container so that areas underneath the shaft seal(s) can also be sterilized.
