The device description and performance studies focus on the chemical composition, sterility, and biocompatibility of a solution used for organ preservation, with no mention of AI or ML technologies.
Yes.
The device is used for the "flushing, storage and transportation of isolated lungs after removal from the donor in preparation for eventual transplantation into a recipient," which falls under the definition of a therapeutic purpose for organ preservation.
No
Explanation: The device is a solution used for the flushing, storage, and transportation of isolated lungs. Its purpose is to preserve organs, not to diagnose medical conditions or provide diagnostic information.
No
The device description clearly states it is a sterile, clear, non-pyrogenic, physiological salt solution supplied in LDPE bottles, which are physical components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "flushing, storage and transportation of isolated lungs after removal from the donor in preparation for eventual transplantation into a recipient." This describes a solution used outside the body to preserve an organ, not a test performed on a biological sample to diagnose a condition or provide information about a patient's health.
- Device Description: The description details a "physiological salt solution for hypothermic flushing, storage, and transportation of human lungs outside the human body." This reinforces its role in organ preservation, not diagnostic testing.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting analytes, or providing diagnostic information.
- Performance Studies: The performance studies focus on chemical composition, sterility, pyrogenicity, stability, and biocompatibility – all relevant to a solution used for organ preservation, but not typical for IVD performance evaluation (which would involve metrics like sensitivity, specificity, etc.).
Therefore, this device falls under the category of a medical device used for organ preservation, not an in vitro diagnostic device.

Device Description
Low Potassium Dextran (LPD) Solution is a sterile, clear, non-pyrogenic, physiological salt solution for hypothermic flushing, storage, and transportation of human lungs outside the human body. LPD Solution is acidic and is adjusted shortly before use to pH 7.4 by the addition of Tris Diluent.
LPD Solution with Tris Diluent is supplied as 1 liter of LPD Solution in a low density polyethylene (LDPE) bottle (8 per pack), co-packed with one single-use bottle of Tris Diluent. Tris Diluent is also supplied separately in an eight-unit pack. Each container of LPD Solution and Tris Diluent is single-use.

Summary of Performance Studies
Chemical composition testing results have confirmed that LPD Solution and Tris Diluent have the same chemical composition as Perfadex and THAM, respectively.
Results of sterility and pyrogenicity testing on LPD Solution and Tris Diluent have shown that both solutions are sterile with a Sterility Assurance Level (SAL) of 106 and nonpyrogenic, similar to Perfadex and THAM. Stability testing, including analysis of chemical characteristics, particulate matter, and sterility assessment, has been conducted on LPD Solution and Tris Diluent to verify the shelf life. The results have verified the shelf life for LPD Solution and Tris Diluent, as manufactured and sterilized.
Biocompatibility test results have shown that LPD Solution and LPD Solution after pH adjustment by Tris Diluent meet the requirements of ISO 10993-1.
Results of testing for USP conformance, pH adjustment of LPD Solution with Tris Diluent, verification of fill volume, mechanical requirements, and summative usability testing did not raise any new questions of the safety or effectiveness.
