The device description clearly outlines physical components (tubing, cassette, connectors, check valve) and bench performance testing related to these physical components. There is no mention of software as a component or function of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide fluid distension and irrigation of joint cavities during surgical procedures. This is a direct intervention on the patient's body for therapeutic and diagnostic purposes during the procedure, not for testing samples outside the body to diagnose a condition.
- Device Description: The device is tubing and a cassette used to deliver fluid from a pump to the surgical site. This is a medical device used in a surgical setting, not a device designed to analyze biological samples.
- Lack of IVD Characteristics: The description does not mention any components or functions related to analyzing blood, urine, tissue, or other biological samples to provide diagnostic information. There is no mention of reagents, assays, or any form of in vitro testing.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This device does not fit that description.

Differences between the Proposed and Predicate Devices
Tubing Specifications:
The difference in inner diameter is negligible as verification testing provided in this submission demonstrates that this difference has no effect on the safety or effectiveness of the device.
The difference in length of the tubing is also negligible as verification testing provided in this submission demonstrates that the difference has no effect on the safety or effectiveness of the device.
6
These minor differences in the proposed device raise no new questions of safety or effectiveness, therefore the proposed device is substantially equivalent to the predicate device.
Pressure Sensing Mechanism:
The proposed device aids the CrossFlow Integrated Arthroscopy pump in measuring pressures in the joint space via a pressure dampening chamber housed in the cassette of Day-Use Inflow Cassette Tubing. The predicate device contains an external pressure chamber that acts similarly to the pressure dampening chamber in sensing pressure fluctuations.
This minor difference in how pressure is measured in the proposed device raises no new questions of safety or effectiveness, therefore the proposed device is substantially equivalent to the predicate device.
Tubing Cassette
Both devices are accessories to irrigation pumps that operate on the peristaltic principle where roller wheels are spun against soft tubing to create the flow of fluid within the tubing. The devices are different in how the tubing interfaces with the roller wheels of the pump. The predicate device requires the user to manually place the tubing inside the console and around the roller wheels while the proposed device simply requires the user to insert a cassette containing the peristaltic tubing into the cassette.
The cassette includes a Radio-frequency Identification (RFID) component that allows the CrossFlow Arthroscopy Pump to recognize tubing cassettes as either new or expired. The predicate device does not include any technology that allows the pump to differentiate between new tubing and tubing that has been used after the intended product lifetime (one surgical day).
This minor difference in the proposed device raises no new questions of safety or effectiveness, therefore the proposed device is substantially equivalent to the predicate device.
Disinfection
A disinfection method was developed for the proposed device to prevent cross-contamination of the connector between cases. Inadvertent and undetected contamination of the device is prevented by disinfecting the connector after each case. Complete disinfection are provided in Section 13 - Labeling. The predicate device labeling does not contain disinfection instructions to ensure safe reprocessing of the device.
This difference in the proposed device raises no new questions of safety or effectiveness, therefore the proposed device is substantially equivalent to the predicate device.
7
Device Lifetime
The proposed device can be used for a single day's cases - no more than 10 cases, 8 hours of active use, or 24 hours from point of first use, which is based on data from a high case-volume day at a high volume arthroscopy surgery center. This claim is supported by the performance testing. Full test summaries and results can be found in Section 18 - Performance Testing -Bench. The predicate device is also intended to be used for a single day's cases or one surgical day however they provide no definition of one surgical day. Based on the data obtained, one surgical day will not exceed 8 hours of active use or 10 cases performed within a 24 hour period.
This difference in the proposed device labeling raises no new questions of safety or effectiveness, therefore the proposed device is substantially equivalent to the predicate device.
Any technological differences between the Stryker CrossFlow Day-Use Inflow Cassette Tubing and Patient-Use Tubing and the predicate devices do not raise new questions of safety or effectiveness.
6. Performance Testing
The Stryker CrossFlow Day-Use Inflow Cassette Tubing and Patient-Use Tubing were evaluated in accordance with internal design specification and with the applicable performance standards as required by the risk analysis. The assessment of non-clinical performance data supports the substantial equivalence determination. The following non-clinical tests were conducted and are summarized in this submission:
Biocompatibility was assessed in accordance with ISO 10993-1:2009 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing within a Risk Management Process" and related collateral standards for direct and indirect patient contacting materials (see Section 15 - Biocompatibility).
Sterilization was assessed in accordance with ISO 11135:2014 - "Sterilization of health-care products - Ethylene Oxide - Requirements for the development, validation and routine control of a sterilization process for medical devices". Sterilization residuals were assessed in accordance with ISO 10993-7:2008 - "Biological evaluation of medical devices - Part 7: Ethylene oxide sterilization residuals" (see Section 14 - Sterilization and Shelf Life).
Bench performance testing was conducted to ensure that the device functioned as intended and met design specifications and acceptance criteria based off of predicate data. The following performance tests were executed in support of the substantial equivalence determination:

Test results obtained verified the safety and effectiveness of the device per design specifications and applicable standards when compared to bench testing. The test results support the substantial equivalence of the Stryker CrossFlow Day-Use Inflow Cassette Tubing and Patient-Use Tubing compared to the predicate devices. Full test summaries and results can be found in Section 18 – Performance Testing – Bench.

7. Nonclinical Testing
When the proposed device is in use certain components will indirectly contact the patient. The materials used were analyzed in accordance with ISO 10993-1:2009. Test results show that the device meets all applicable requirements.
The nonclinical tests conducted and referenced in this premarket notification show that the proposed device meets or exceeds the performance requirements, and demonstrate the device is as safe, as effective, and performs as well as or better than the predicate device based on competitor test data.
8. Conclusion
The proposed and predicate devices are similar in design and performance specifications. Clinical testing was not required to demonstrate substantial equivalence. Based on the evaluation of the indication for use, technological characteristics, performance testing, nonclinical testing, and comparison to the predicate devices, the Stryker CrossFlow Day-Use Inflow Cassette Tubing and Patient-Use Tubing raises no new questions of safety and effectiveness when compared to the predicate device and is thus considered substantially equivalent.
