BD Nexiva™ Diffusics™ Closed IV Catheter Systems are intended to be inserted into a patient's vascular system for short term use to sample blood, monitor blood pressure, or administer fluids. These devices may be used for any patient population with consideration given to adequacy of vascular anatomy, procedure being performed, fluids being infused, and duration of therapy. These devices are suitable for use with power injectors set to a maximum pressure of 325 psi (2240 kPa) when access ports not suitable for use with power injectors are removed.

BD Nexiva Diffusics closed IV catheter systems are over-the-needle, intravascular catheters. These devices have a radiopaque BD Vialon catheter with side holes located near the tip of the catheter which are designed to optimize power injection procedures. These devices also have a needle, needle shield, septum, stabilization platform, integrated extension tubing, clamp, Luer connector, and vent plug. The Luer connector displays gauge-specific maximum flow rate and the maximum power injector pressure limit setting. The needle and catheter are protected by a needle cover. An end cap with protective cover is provided in the unit package. The closed system is designed to keep blood contained within the device

It broadly mentions "Summary of Performance tests completed on the subject device were limited to those tests Performance required to support a determination of substantial equivalence to the predicate Tests devices." It also states, "When technological characteristics between the subject and predicate devices were found to be identical, results of performance testing conducted on the predicate devices were applied to the subject device."

• Sample size: Not explicitly stated. The tests are industrial-standard tests for medical device components.
• Data provenance: Not explicitly stated, though it implicitly refers to "design verification" and "risk analysis" conducted by the manufacturer, Becton Dickinson Infusion Therapy Systems Inc. The testing results are presented as having met internal, pre-determined criteria. Given the nature of a 510(k) submission for a material change, the testing would be prospective for the modified component.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

This information is not applicable to this type of device and submission. The tests are physical, chemical, and biological performance tests for a medical device, not clinical studies requiring expert interpretation of outcomes. The "ground truth" is defined by the technical specifications and standards (e.g., ISO 10993-1, USP ) that the device must meet.

4. Adjudication Method for the Test Set

This information is not applicable. The nature of the tests (e.g., measuring pull force, pressure, or biological response) does not involve adjudication by human readers or experts in the sense of clinical image interpretation or diagnostics. The results are objective measurements compared against pre-defined acceptance criteria.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

No, an MRMC comparative effectiveness study was not done. This is a 510(k) submission for a Class II medical device (intravascular catheter) involving a material change. MRMC studies are typically associated with diagnostic imaging devices where human interpretation is a key component of the clinical workflow.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done

No, a standalone performance study was not done. This device is a physical medical device, not a software algorithm.

7. The Type of Ground Truth Used

The "ground truth" for the performance tests is derived from engineering specifications, recognized industry standards (e.g., ISO 10993-1 for biocompatibility, USP for particulate analysis), and internal design requirements developed by BD according to 21 CFR 820.30 Design Controls. These objective criteria define what constitutes acceptable performance for the device and its material components.

8. The Sample Size for the Training Set

This information is not applicable. This is a submission for a physical medical device, not an AI/ML algorithm that requires a "training set."

9. How the Ground Truth for the Training Set Was Established

This information is not applicable as there is no training set for this device.

BD Nexiva closed IV catheter systems are over-the-needle, intravascular catheters. These devices have a radiopaque BD Vialon™ catheter, needle, needle shield, septum, stabilization platform, integrated extension tubing, clamp, Luer adapter, vent plug and, with dual port configurations, a pre-attached BD Q-Syte Luer Access Split Septum. The needle and catheter are protected by a needle cover. For dual port configurations, a BD Q-Syte device or an end cap with protective cover is provided in the unit package. The closed system is designed to keep blood contained within the device throughout the insertion process. The septum is designed to wipe visible blood from the needle surface as the needle is withdrawn from the catheter, further reducing the risk of blood exposure. The needle tip is passively protected when the needle is removed, reducing the risk of accidental needlestick injury. These devices have BD Instaflash™ Needle Technology, allowing for immediate visualization of blood along the catheter. Continuous blood return is seen in the extension tubing. The vent plug prevents blood leakage from the extension tubing during insertion. Both the stabilization platform and Luer connector are color coded to indicate catheter gauge size (24GA (0.7 mm)=Yellow, 22GA (0.9 mm)=Blue, 20GA (1.1 mm)=Pink, 18GA (1.3 mm)=Green).
