The MedSource TrueSafe Safety IV Catheter and the MedSource TrueSafety IV Catheter is indicated to sample blood or administer fluids intravenously. The MedSource TrueSafe Safety IV Catheter and the MedSource TrueSafe Comfort Safety IV Catheter may be used for any patient population with consideration given to adequacy for the vascular anatomy appropriateness for the solution being administered and duration of the therapy.
The MedSource TrueSafe Safety IV Catheter and the MedSource TrueSafe Comfort Safety IV Catheter are safety medical devices used for inserting a catheter into a patient's body for purpose of delivery of fluids or drainage of fluids from the patient. The MedSource TrueSafe Safety IV Catheter and the MedSource TrueSafe Comfort Safety IV Catheter are comprised of the following components: protective needle cover, color-coded catheter hub, radiopaque catheter tube, catheter holder, needle guide, medical grade stainless steel needle hub, porous plug and gauge chamber. The components combine for an ergonomic design that incorporate a safety feature that when the device is withdrawn, the needle is completely enclosed within the chamber protecting healthcare and other personnel from exposure to patient body fluids after the device has been discarded post-use. The retraction mechanism is activated by the push of a button.
This document describes the safety and performance testing for the MedSource TrueSafe Safety IV Catheter and MedSource TrueSafe Comfort Safety IV Catheter.

2. Sample Size Used for the Test Set and Data Provenance:
The document mentions several types of testing:
- Nonclinical Bench Performance testing: The specific sample sizes for each of the listed bench tests (e.g., flow rate, corrosion, tensile strength) are not explicitly provided in the summary. However, these are generally performed on a sufficient number of units to demonstrate compliance with the referenced ISO standards.
- Simulated Clinical Use Testing: This test used a sample size of 500 units.
- Data Provenance: The document does not specify the country of origin of the data or whether the studies were retrospective or prospective. Given that it's a 510(k) submission and the tests are bench and simulated clinical use, they are inherently prospective in nature, performed specifically for regulatory submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts:
For the nonclinical bench tests and simulated clinical use testing described, there is no mention of "experts" in the sense of medical professionals establishing a ground truth. These tests rely on predefined engineering and scientific criteria (e.g., ISO standards, physical measurements). The "ground truth" for these tests is the objective measurement against the specified criteria.
4. Adjudication Method for the Test Set:
Not applicable. The tests described are objective, quantitative measurements or visual assessments against predefined criteria from standards (e.g., ISO standards). There is no "adjudication" necessary between multiple observers or experts.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
No, an MRMC comparative effectiveness study was not conducted or reported in this document. This submission focuses on the substantial equivalence of the device through bench and simulated use testing, not on comparative effectiveness with human readers.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Not applicable. This device is a physical medical device (an IV catheter), not an algorithm or AI system. Therefore, standalone algorithm performance is not relevant.
7. The Type of Ground Truth Used:
The ground truth for the performance tests is based on:
- Established engineering and performance standards: Primarily ISO 10555-1 and ISO 10555-5 for mechanical and functional aspects, and ISO 10993 series for biocompatibility.
- Objective physical measurements: For parameters like flow rate, tensile force, needle stick force, distance measurements, etc.
- Visual inspection criteria: For aspects like needle point defects, corrosion, and resistance to disinfection.
- Pre-defined pass/fail criteria: For all tests, specific thresholds or observations determine a "Pass" or "Fail."
8. The Sample Size for the Training Set:
Not applicable. This device is a physical product and not an AI/ML algorithm that requires a "training set."
9. How the Ground Truth for the Training Set was Established:
Not applicable, as there is no training set for this physical device.
§ 880.5200 Intravascular catheter.
(a)
Identification. An intravascular catheter is a device that consists of a slender tube and any necessary connecting fittings and that is inserted into the patient's vascular system for short term use (less than 30 days) to sample blood, monitor blood pressure, or administer fluids intravenously. The device may be constructed of metal, rubber, plastic, or a combination of these materials.(b)
Classification. Class II (performance standards).
