No
The device description and performance studies focus on the chemical composition and physical properties of a preservation solution, with no mention of AI or ML technologies.
Yes
The device is used for organ preservation and does not directly treat a disease or condition in a living organism. Its purpose is to maintain the viability of organs for transplantation, which is a supportive rather than a therapeutic function.
No
The device is a preservation solution used for organs prior to transplantation, not a tool for diagnosing medical conditions. It aids in maintaining organ viability, not in identifying diseases or pathological states.
No
The device description clearly indicates it is a solution (liquid) used for organ preservation, not a software program.
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 perfusion, flushing, and preservation of donor organs (kidneys, liver, pancreas, and heart) prior to and during transplantation. This is a direct intervention on the organ itself, not a test performed in vitro (outside the body) on a sample from the body to diagnose a condition or provide information about a physiological state.
- Device Description: The description details the composition and function of the solution in preserving the organ's viability during storage and transport. It focuses on the solution's properties for maintaining the organ's integrity, not for analyzing a biological sample.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information. The device's function is entirely focused on the physical preservation of the organ.
Therefore, CUSTODIOL® HTK solution falls under the category of a medical device used in the context of organ transplantation, but it is not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
CUSTODIOL® HTK solution is indicated for perfusion and flushing of donor kidneys, liver, pancreas and heart prior to removal from the donor or immediately after removal from the donor. The solution is left in the organ vasculature during hypothermic storage and transportation to the patient. CUSTODIOL® HTK solution is not indicated for continuous machine perfusion of donor organs.

Device Description
The CUSTODIOL® HTK solution is intended for perfusion and flushing donor kidney, liver, heart, and pancreas prior to removal from the donor and for preserving these organs during hypothermic storage and transport to the recipient. CUSTODIOL® HTK solution is based on the principle of inactivating organ function by withdrawal of extracellular sodium and calcium, together with intensive buffering of the extracellular space by means of histidine/histidine HCI, so as to prolong the period for which the organs will tolerate interruption of blood and oxygen supply. Only a small portion of the osmolality of the CUSTODIOL® HTK solution is due to the sodium and potassium. The composition of HTK is similar to that of extracellular fluid. All of the components of the CUSTODIOL® HTK solution occur naturally in the body. The CUSTODIOL® HTK solution is relatively low in potassium concentration so that residual solution in the transplanted organ poses no danger to the recipient. This is particularly important in orqans that take up relatively large amounts of the perfusate, which may find its way into the recipient's circulation. The CUSTODIOL® HTK solution has a low viscosity, even at low temperatures. This characteristic assures rapid flow rates during initial perfusion, allowing the organ to be quickly cooled.

6.2. Animal Testing
Animal tests are deemed not necessary to demonstrate safety of CUSTODIOL® HTK Solution.
6.3. Clinical Testing
Clinical data are available and able to demonstrate reliability of CUSTODIOL® HTK Solution. To support the substantial equivalence for this 510(k), no further clinical data were required. The safety and efficacy of CUSTODIOL® HTK Solution as an organ preservation solution has not been clinically demonstrated in extended criteria donors (ECD), donation after cardiac arrest (DCD) or other marginal donor populations.
7. 510(k) Summary Conclusions
Based on the available 510(K) information, Dr. Franz Köhler Chemie GmbH CUSTODIOL® HTK solution is considered "substantially equivalent" to selected predicate device. Differences concerning the clinical application, intended use, biological aspects, design, technical features as well as performance specifications do not lead to any new risks. Both tests and validations performed on our devices support our statements.
