Intended Use

The Merit RadialFlo Arterial Catheter is a device that is inserted into the patient's vascular system for short term use (less than 30 days) to sample blood and monitor blood pressure. The Merit RadialFlo Arterial Catheter may be used for any patient population with consideration given to adequacy of vascular anatomy and appropriateness of procedure.

Device Description

The Merit RadialFlo Arterial Catheter is an intravascular catheter designed to access the vasculature to sample blood and monitor blood pressure. The device is equipped with a Floswitch to limit blood spill or control flow as needed. The needle includes a unique notch to provide instant blood return upon vessel entry. The radiopaque catheter provides visibility under X-ray and fluoroscopy.

The arterial catheter is intended to be in contact with the circulating blood for a prolonged (24 hours to 30 days) duration. The steel needle is in contact with circulating blood for a limited (<24 hours) duration and the flow control plug has indirect blood path contact. All the materials used in Merit RadialFlo Arterial Catheter are biocompatible.

AI/ML Overview

The provided text describes the Merit RadialFlo Arterial Catheter, which is an intravascular catheter for short-term use (less than 30 days) to sample blood and monitor blood pressure. The document focuses on regulatory approval (510(k) submission) and demonstration of substantial equivalence to predicate devices, rather than a study proving the device meets explicit clinical outcome acceptance criteria in an AI context.

Therefore, many of the requested items (e.g., sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC study, standalone performance, training set size) are not applicable or cannot be extracted from this documentation, as it pertains to a medical device's physical and biological performance rather than an AI/ML diagnostic or prognostic system.

However, I can provide information on the device's acceptance criteria based on the regulatory standards it meets and its reported performance against those technical standards.

Study Details:

The document describes a series of bench tests and biocompatibility tests to demonstrate that the Merit RadialFlo Arterial Catheter meets established safety and performance standards for its intended use. This is a traditional medical device approval process, not an AI/ML software validation.

2. Sample size used for the test set and the data provenance:

  • Sample size: Not explicitly stated as a single "test set" in the context of an AI/ML study. The studies refer to "a battery of tests" and "results of the testing" which typically involve specific numbers of devices or test samples for each individual test (e.g., a certain number of catheters for tensile strength, a certain number of samples for cytotoxicity testing). These numbers are not provided in the summary.
  • Data provenance: The tests are conducted according to internationally recognized consensus standards (ISO, ASTM, IEC, USP). This implies controlled laboratory settings and standardized methodology, rather than patient data from a specific country or retrospective/prospective clinical data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

  • Not applicable. Ground truth in this context refers to the defined acceptance criteria of the technical and biological standards, not expert medical opinion on a specific condition.

4. Adjudication method for the test set:

  • Not applicable, as this refers to a medical device's physical and biological performance against predefined technical standards, not interpretation of data by human readers.

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:

  • Not applicable. This device is a physical intravascular catheter, not an AI/ML diagnostic or assistance tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

  • Not applicable. This device does not involve an algorithm.

7. The type of ground truth used:

  • Technical Standards and Specifications: The ground truth for performance is established by the acceptance criteria defined within the referenced international standards (ISO 10555-1, ISO 10555-5, ISO 80369-7, ISO 9626, IEC 62366-1, ISO 2233, ISO 11607-1, ISO 11607-2, ASTM D4169-16, ASTM F1980-16, ISO 11135, AAMI TIR 28, AAMI/ANSI ST72).
  • Biological Compatibility Principles: The ground truth for biocompatibility is established by the acceptance criteria defined within the referenced international standards (ISO 10993-1, ISO 10993-4, ISO 10993-5, ISO 10993-10, ISO 10993-11, ISO 10993-7) and the United States Pharmacopeia 41.

8. The sample size for the training set:

  • Not applicable. This type of device approval does not involve a "training set" in the context of AI/ML.

9. How the ground truth for the training set was established:

  • Not applicable.

The Merit RadialFlo Arterial Catheter is a device that is inserted into the patient's vascular system for short term use (less than 30 days) to sample blood and monitor blood pressure. The Merit RadialFlo Arterial Catheter may be used for any patient population with consideration given to adequacy of vascular anatomy and appropriateness of procedure.
Intended UseThe Indications for Use statement for the Merit RadialFlo Arterial Catheter device is same as the predicate device (K151698) except that the predicate device has additional use to administer fluids intravenously. Subject device has one less product claim and product does not have therapeutic effect. The difference does not affect the safety and effectiveness of the device relative to the predicate. Both the subject and predicate devices follow 21 CFR 880.5200 to sample blood and monitor blood pressure.
Device DescriptionThe Merit RadialFlo Arterial Catheter is an intravascular catheter designed to access the vasculature to sample blood and monitor blood pressure. The device is equipped with a Floswitch to limit blood spill or control flow as needed. The needle includes a unique notch to provide instant blood return upon vessel entry. The radiopaque catheter provides visibility under X-ray and fluoroscopy.The arterial catheter is intended to be in contact with the circulating blood for a prolonged (24 hours to 30 days) duration. The steel needle is in contact with circulating blood for a limited (<24 hours) duration and the flow control plug has indirect blood path contact. All the materials used in Merit RadialFlo Arterial Catheter are biocompatible.
Comparison toPredicate DeviceThe proposed Merit RadialFlo Arterial Catheter incorporates similar intended use, design and principle of operation as the predicate devices. Any differences in materials used or specification are supported by the subject device's compliance with FDA recognized standards ISO 10555-1 and ISO 10555-5. The subject device is substantially equivalent to the predicate device (K151698).The technology and design of the Flowswitch is the same as reference device. The material used on the subject device is same as the reference device (K850460) except the Flowswitch button is made using polyphenylene oxide but this has no body contact. There is also an additional component which is the flow control plug that is made of polypropylene with filter membrane to limit blood spill. The flow control plug has indirect blood contact.
