No
The description focuses on the mechanical and material aspects of the catheter and its heat exchange function, with no mention of AI or ML for data analysis, control, or decision-making.
Yes
The device is used to achieve and/or maintain normothermia or induce, maintain, and reverse mild hypothermia in patients, which directly treats or manages a physiological state.
No
The device is described as an Intravascular Heat Exchange Catheter used for thermal regulation (heating or cooling) of patients, not for diagnosing conditions or diseases.
No
The device description clearly details a physical catheter, a start-up kit, and a console, all of which are hardware components used for heat exchange within the patient's body. The software component, if any, would be part of the console controlling the system, but the device itself is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to achieve and maintain normothermia or induce, maintain, and reverse mild hypothermia in patients during surgery and recovery. This is a therapeutic intervention, not a diagnostic one.
- Device Description: The device is a catheter designed for heat exchange within the patient's bloodstream. It circulates saline in a closed loop to warm or cool the blood. This is a physical intervention, not a test performed on a sample taken from the body.
- Lack of Diagnostic Elements: There is no mention of analyzing samples (blood, tissue, etc.) or providing information about a patient's health status based on such analysis. The device directly modifies the patient's body temperature.
- Performance Studies: The performance studies described focus on bench performance, biocompatibility, and shelf life. These are relevant to the safety and functionality of a therapeutic device, not the accuracy of a diagnostic test. Key metrics mentioned are related to the device's physical properties and biological interactions, not diagnostic metrics like sensitivity or specificity.
In summary, the Solex Intravascular Heat Exchange Catheter is a therapeutic device used to regulate body temperature, not a diagnostic device used to test samples for information about a patient's health.

Device Description
The ZOLL Solex Intravascular Heat Exchange Catheter (Solex Catheter) is a sterile, single use 9.3F flexible catheter designed for placement in the superior vena cava from an insertion site in the jugular vein. The Solex Catheter is connected to a single use, disposable CoolGard 3000" or Thermogard XP® Start-Up Kit (SUK) and the CoolGard 3000" or Thermogard XP® Console, all of which comprise the ZOLL Intravascular Heat Exchange System. The Start-Up Kit (SUK) and the CoolGard 3000 or Thermogard XP Console are supplied separately. The ZOLL Heat Exchange System is also designed for use with an off-the-shelf temperature probe. The Solex Catheter is comprised of a polyurethane shaft and a serpentine shaped PET balloon at the distal end. The blood contact surfaces of the catheter incorporate a hydrophilic heparin coating as an anti-thrombogenic agent.
The catheter has five lumens, two of which when connected to the Start-Up Kit, are used to circulate sterile saline in a closed loop circuit for heat exchange with the blood in the central venous system. Heated or chilled saline is pumped through the heat exchange lumens, inflating the diameter of the PET balloon that interfaces with the patient's blood system to warm or cool circulating blood. The inflow/outflow lumens form a closed-loop system through which the heated or chilled saline circulates. The heated or chilled saline is not infused into the patient. Additional lumens of the Solex Catheter consist of a 0.032" guidewire compatible lumen that can also be used as a primary infusion lumen, and two additional infusion lumens within the catheter shaft.

IV. Summary of the Nonclinical Tests Performed:
Nonclinical testing was performed to ensure that the modified ZOLL Solex Catheter meets its predetermined design and performance specifications and that the product is substantially equivalent to the predicate devices (K081936 and K101987).
The modified Solex Catheter is identical to the 510(k) cleared Solex Catheter in terms of intended use/indications for use and principles of operation, and has equivalent technological characteristics. Minor design modifications have been incorporated into the catheter design to improve manufacturability of the device. Nonclinical testing completed includes Bench Performance, Biocompatibility, and Shelf Life Testing to support the labeled expiration date. The non-clinical test results demonstrate that the modified Solex Catheter continues to meet product design specifications.
Bench Performance
Bench performance testing of the modified Solex Catheter was performed to verify that product design specifications were met at T=0 and after real time aging to support the labeled expiration date. Testing completed includes the following: catheter visual inspection, dimensional measurements, life testing, flow rate and pressure monitoring, heat exchange testing, air/liquid leakage testing, burst testing, flex and fatigue testing, and tensile strength testing. Where applicable, testing was performed in accordance with the catheter performance requirements of
7
ISO 10555-1:2013. The results of the design verification testing demonstrate that the modified Solex Catheter meets its design performance specifications at T=0 and at its labeled expiration date.
Biocompatibility
The modified Solex Catheter is fabricated with similar materials and components as the predicate Solex Catheter and other cleared ZOLL Catheters. In addition, the Solex Catheter utilizes the identical SurModics Heparin Coating as the predicate ZOLL Cool Line, ICY and Quattro Catheters 510(k) cleared in K101987, using the same material substrates. According to ISO 10993-1:2009, Biological Evaluation of Medical Devices – Part 1: Guidance on Selection of Tests, the Solex Catheter is categorized as an "external communicating, blood contact device with prolonged exposure (>24 hours to 30 days)". Based on this categorization, the Solex Catheter was tested for Cytotoxicity, Sensitization, Acute Systemic Toxicity, Subacute Toxicity, Genotoxicity, Implantation, and Hemocompatibility. The results of the testing demonstrate that the Solex Catheter is biocompatible for its intended use.
V. Summary of Clinical Tests Performed:
Clinical evaluations were not performed for the modified Solex Catheter and were not necessary to demonstrate substantial equivalence of the modified Solex Catheter to the predicate devices (K081936 and K101987).
VI. Substantial Equivalence:
The modified Solex Catheter has the same intended use / indications for use as the 510(k) cleared Solex Catheter (K081936). The modified Solex Catheter utilizes the identical SurModics Applause Heparin Coating as other currently cleared ZOLL Catheters (Cool Line, ICY and Quattro - K101987) and has similar technological characteristics as the currently cleared Solex Catheter. The results of the bench performance, biocompatibility and shelf life testing demonstrate that the modifications do not affect the performance or function of the device. The minor differences in the design between the modified and cleared Solex Catheters, as well as other ZOLL predicate Catheters, do not raise any new types of safety or effectiveness questions as confirmed by design verification testing. Therefore, the modified Solex Catheter is substantially equivalent to the previously cleared predicate devices.
VII. Conclusions:
ZOLL concludes that based on the results of the bench performance, biocompatibility and shelf life testing, that the Solex Catheter is substantially equivalent to the predicate devices.
