Tissue heart valve (THV) humidor packaging system
View Patent ↗A prosthetic valve packaging system includes a jar, a lid, a lid liner, and a humectant. The jar has a closed end, an open end, a side wall and an interior sized to receive the prosthetic heart valve. The lid is connected to the open end of the jar. The lid liner includes a rim sandwiched between the lid and the side wall of the jar to provide a fluid-tight seal. The humectant is supported within the interior of the jar. The humectant may be supported by the lid liner. The lid liner may include one or more windows so that the humectant may provide a desired humidity to the inside of jar to maintain a desired water content in the tissue of the valve. The system may obviate the need to store the valve in a dry state, or to otherwise store the valve submerged in an aldehyde solution.
1. A method of packaging a prosthetic valve in a packaging system, the method comprising:
providing a jar having a closed end, an open end, a sidewall and an interior;
positioning the prosthetic valve within the interior of the jar;
positioning a humectant within the interior of the jar;
connecting a lid to the jar to close the open end of the jar; and
coupling a gas permeable barrier to the jar after positioning the prosthetic valve within the interior of the jar, but before positioning the humectant within the interior of the jar,
wherein the prosthetic valve is not submerged in a storage solution when the lid is connected to the jar.
2. The method of claim 1 , wherein the step of positioning the humectant within the interior of the jar includes supporting the humectant within the lid.
3. The method of claim 1 , wherein the connecting step includes compressing a compressible seal between the lid and the side wall of the jar to seal the jar in a fluid-tight fashion.
4. The method of claim 1 , further comprising sterilizing the prosthetic valve before positioning the humectant within the interior of the jar.
5. The method of claim 4 , wherein the gas permeable barrier is positioned between the humectant and the prosthetic valve.
