The device description and performance studies focus on passive temperature control and monitoring, with no mention of AI or ML technologies.
No.
Explanation: The device is intended for the static hypothermic preservation of organs during transport for transplantation, not for direct therapeutic treatment of a patient.
No
This device is intended for the static hypothermic preservation and transport of hearts and kidneys, not for diagnosing conditions or diseases. It monitors temperature during transport but does not provide diagnostic information about the organ or patient.
No
The device description explicitly details physical components like an outer transport shipper, inner and outer hard shell assembly, and a data logger, indicating it is a hardware device with potentially integrated software for temperature monitoring.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the preservation and transportation of organs (hearts and kidneys) for transplantation. This is a device used on the organ itself, not for testing a sample from the body to diagnose or monitor a condition.
- Device Description: The description details a system for packaging and maintaining the temperature of organs during transport. It includes components like shippers, canisters, and a data logger for temperature monitoring. None of these components are designed for in vitro diagnostic testing.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, assays, or any other elements typically associated with in vitro diagnostics.
The device is clearly intended for the physical handling and preservation of organs, which falls outside the scope of in vitro diagnostics.

Intended Use / Indications for Use
SherpaPak Cardiac Transport System
The SherpaPak Cardiac Transport System is intended to be used for the static hypothermic preservation of hearts during transportation and eventual transplantation into a recipient using colutions indicated for use with the heart.
The intended organ storage time for the SherpaPak Cardiac Transport System is up to 4 hours.
Donor hearts exceeding clinically accepted static hypothermic preservation times should be evaluated by the transplant surgeon to determine transplantability in accordance with accepted clinical guidelines and in the best medical interest of the intended recipient.
SherpaPak Kidney Transport System
The SherpaPak Kidney Transport System is intended to be used for the static hypothermic preservation of kidney organs during transportation and eventual transplantation into a recipient using colutions indicated for use with this organ.
The SherpaPak Kidney Transport System can maintain the donor organ storage temperature between 4 C and 8 C through 24 hours.

Device Description
The SherpaPak Cardiac Transport System and SherpaPak Kidney Transport System result from modifications made to the cleared Sherpa Pak Cardiac Transport System and Sherpa Pak Kidney Transport System most recently cleared under K133432 and K133694, respectively. The principle of operation of the modified devices is identical to that of the cleared devices, namely, cold static storage and transportation of donor hearts (Cardiac version) or donor kidneys (Kidney version), using cleared preservation solutions specific to the organ type being transported. Further, the modified designs have the same indications for use and utilize the same technology as the predicate devices.
The subject SherpaPak design (cardiac and kidney) like its predecessor, consists of 1) outer transport shipper which contains within it various non-ice based temperature controlled packaging elements, 2) an inner and outer hard shell assembly (i.e. Sherpa Canister/Sherpa Shell) which provides a double, rigid barrier shipper in which the heart/kidney is immersed and suspended in a cold storage solution cleared for use in storing and transporting donor hearts/kidneys, and 3) a data logger that monitors and displays the temperature of the cold storage solution in which the heart/kidney is stored during transport.
The following modifications were made from the predicate to subject devices:
-
- Change to the exterior shipping container to incorporate insulating capabilities using rigid EPS material,
-
- Elimination of separate EPS and PIR panels which are no longer necessary to maintain temperature during preservation and transport (reducing system bulk),
-
- Modification of the Phase Change Material (PCM) cooling packs and configuration used to maintain temperature during preservation and transport,
-
- Direct measurement of cold storage solution temperature using a temperature probe inserted within the Sherpa Canister,
-
- Modifications to the Sherpa Canister and Shell to a) incorporate the ability to transmit temperature data from the temperature probe to the data logger and ergonomic changes providing easier handling during use (e.g., handle on the Sherpa Shell lid), and
-
- Ability to use a mobile app to see temperature during transport.

Functional Testing:
The premarket notification was submitted to implement modifications to the currently cleared Sherpa Pak Cardiac and Kidney Transport Systems. Testing performed related to the modifications made to the cleared devices included the following:
- . Biocompatibility testing of any new materials that contact the body
- The biocompatibility evaluation for the modified devices was conducted in o accordance with International Standard ISO 10993-1: 2009 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The battery of testing included the following tests: Cytotoxicity, Sensitization, Irritation, Acute Systemic toxicity, Material Mediated Pyrogenicity, Hemocompatibility, and Genotoxicity testing
- Electrical Safety and EMC testing in conformance with ●

- The purpose of this test was to evaluate the entire System when subjected to the o rigors of transportation. The System was tested using a modified protocol per ASTM D4169-09. The protocol tested vibration and altitude stresses on the system.
- Thermal qualification .
- The modified SherpaPak System is required to store and transport a donor heart o (or kidney) in cold storage solution between 4°C - 8°C for up to 4 hours (cardiac) and 24 hours kidney). This test was performed to demonstrate the system could meet this specification.
- Helium Leak Testing .
- The purpose of this test was to evaluate the seal integrity of the organ container O (Canister and Shell) that contains the donor organ and the cold storage solution. The Canister and Shell are both provided sterile and are intended to maintain sterility during transport of the donor heart in solution.

Conclusion:
The design, intended use, principles of operation, and technological characteristics of the SherpaPak Cardiac Transport System and SherpaPak Kidney Transport System are substantially equivalent to the previously cleared Sherpa Pak Cardiac Transport System and the Sherpa Pak Cardiac Transport System (K133432) and Sherpa Pak Kidney Transport System (K133694), respectively. All of the employed components are very similar to those of the cleared Sherpa Pak devices and utilize the same fundamental scientific technology. The modifications made were such to improve manufacturability and user ergonomics of the system and do not change the devices' intended use. Based upon the descriptive information provided and the testing conducted, the modified SherpaPak Cardiac and Kidney Transport Systems are substantially equivalent to their predicates.
