(55 days)
The PowerPICC Provena Catheters are indicated for short or long-term peripheral access to the central venous system for intravenous therapy, blood sampling, power injection of contrast media, and allows for central venous pressure monitoring. For central venous pressure monitoring, it is recommended that a catheter lumen of 20 gauge or larger be used.
Bard Access Systems, Inc.'s PowerPICC Provena Catheters are sterile, single use devices designed to provide access to the patient's vascular system. The devices are intended for short- or long-term use (>30 days) to sample blood and administer fluids intravenously. The catheters are capable of central venous pressure monitoring, and can withstand power injection of contrast media. The catheters are peripherally inserted central catheters (PICC) and utilize the same placement technique as the predicate devices.
The subject devices included in this notification are of varying French size and catheter configuration types, as summarized in the table below.
Summary of Subject Devices
French size (Number of Lumens)
Catheter Configuration
PowerPICC Provena Catheters
3 French Single Lumen (SL)
4 French Dual Lumen (DL)
The following device descriptors apply to all French sizes and configurations of the subject catheters:
- Catheters are open-ended, radiopaque polyurethane;
- Catheters have a reverse taper design;
- Catheter shaft tubing is marked with depth indicators, with "0" indicated to serve as a reference for the catheter insertion point;
- Purple colorant is included in the catheter material to provide the catheter with an appearance that allows the end user to differentiate Bard's power injectable catheters from other manufacturers' power injectable catheters; and
- Catheter extension leg, luer hub, junction, and clamp ID tags are printed with markings to identify the catheter as PowerPICC Provena Catheters, and include information to facilitate proper use of the device.
The subject devices are provided sterile in basic interventional radiology (IR) as well as basic, full, and max barrier nursing PICC kits with legally marketed components to assist in the placement procedure. These kits are available in both standard and small patient versions.
The provided document describes the acceptance criteria and a detailed study for the C.R. Bard, Inc. PowerPICC Provena Catheters (K162443). This is a medical device, and the study involves a series of performance tests to demonstrate substantial equivalence to a predicate device, rather than a clinical study evaluating AI performance.

2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the exact sample sizes (number of devices tested) for each individual test. It generally references "Bard internal standards and procedures" and relevant ISO standards (e.g., ISO 10555-1:2013) for the testing methodology. These standards typically define acceptable sample sizes for device testing.
The data provenance is implied to be from in-house testing conducted by Bard Access Systems, Inc. There is no mention of country of origin for data if it were to be from external sources, nor does it specify if the data is retrospective or prospective, as this is a device performance study rather than a clinical trial.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This type of information (number and qualifications of experts) is not relevant for this device performance study. The ground truth for these tests is established by objective, measurable engineering and material science standards and physical properties, not by expert interpretation.
4. Adjudication Method for the Test Set
Adjudication methods (like 2+1, 3+1, none) are typically used in clinical studies or studies involving human assessment of data. This document describes a battery of engineering and material science tests. Therefore, no adjudication method as described for clinical data interpretation is applicable or mentioned. The "adjudication" is inherent in the objective measurement against established criteria.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No, a multi-reader multi-case comparative effectiveness study was not done. This document describes the safety and performance testing of a medical device (intravascular catheter), not an AI system. Therefore, there is no mention of human readers, AI assistance, or effect sizes related to AI.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
No, a standalone algorithm performance study was not done. This document pertains to the physical performance of a medical catheter, not an algorithm or AI system.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for the tests described is based on objective, measurable engineering and material properties, and established industry standards. Examples include:
- Physical measurements: OD, ID, length, flow rates, burst pressure, tensile strength.
- Reference: Dimensional Test, Implantable Length, Extension Leg Length, Burst Test, Hydraulic Catheter Burst Test, Extension Leg Burst Test, Power Injection Maximum Flow Rate, Assembly Tensile Test, Shaft Tensile Test, Suture Wing Integrity Test, Priming Volume, Gravity Flow, Pump Flow, Kink Diameter Test, Taper Length.
- Chemical/Biological properties: Biocompatibility outcomes (e.g., absence of biological hazard, lack of sensitization, cytotoxicity, irritation, hemolysis).
- Reference: Biocompatibility Testing, Mechanical Hemolysis Test.
- Functional performance: Absence of leaks, tip stability during power injection, ability to remove stylets easily, adherence of printing.
- Reference: Clamp Engagement, Leak Test, Catheter Collapse Test, Power Injection Conditioning, Tip Stability Test, Stylet Drag Test, Catheter Printing.
- Compliance with published standards: ISO 10555-1:2013 and FDA guidance documents.
8. The sample size for the training set
This is not applicable. This is a device performance study, not an AI model development or validation study. There is no concept of a "training set" in this context.
9. How the ground truth for the training set was established
Not applicable, as there is no training set for an AI model in this document.
§ 880.5970 Percutaneous, implanted, long-term intravascular catheter.
(a)
Identification. A percutaneous, implanted, long-term intravascular catheter is a device that consists of a slender tube and any necessary connecting fittings, such as luer hubs, and accessories that facilitate the placement of the device. The device allows for repeated access to the vascular system for long-term use of 30 days or more, and it is intended for administration of fluids, medications, and nutrients; the sampling of blood; and monitoring blood pressure and temperature. The device may be constructed of metal, rubber, plastic, composite materials, or any combination of these materials and may be of single or multiple lumen design.(b)
