The Surefire High Flow Angiographic Catheter (SAC) is used to facilitate advancement of the Surefire High Flow Microcatheter to the target vessel. The SAC is a single lumen, fixed length guide catheter with a Luer Lock Hub. It is compatible with standard 0.038" guide wires, Luer lock infusion syringes, and rotating hemostatic valves (RHVs). The angiographic catheter has an approximate length of 65 cm (usable length). A reinforced proximal section allows for ease of insertion and the barium sulfate filled extrusion provides clear fluoroscopic images of the shaft. A braided tungsten filled shaped tip provides visual feedback for the location of the guide catheter under fluoroscopy. The distal tip is rounded for atraumatic tracking. A shaped tip will assist to deliver the Surefire High Flow Angiographic Catheter to the desired target site. A peel-away Introducer is supplied with the SAC to insert the shaped tip into a catheter sheath introducer. The system is provided sterile (FO) for single patient use. The Angiographic Catheter is packaged in sealed sterile protective pouches and product boxes.

AI/ML Overview

The Surefire® High Flow Angiographic Catheter is intended for angiographic diagnostic use. The study relied on performance and verification testing to establish substantial equivalence to a predicate device, the Angiodynamics Soft-Vu Angiographic Catheter (K112452).

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

The information provided specifies bench tests were conducted. Details on the specific sample sizes for each individual test (e.g., number of catheters tested for kink radius, pull strength, etc.) are not explicitly stated in the provided summary. The data provenance is from bench testing, which is performed in a controlled laboratory environment and is not tied to specific countries of origin or retrospective/prospective patient data.

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 as the study involved bench testing of a medical device's physical and biological properties, not a clinical study involving experts evaluating patient data or images to establish ground truth.

4. Adjudication method for the test set

This information is not applicable for bench testing. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies where human reviewers assess data.

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 (MRMC) comparative effectiveness study was not conducted. This study focuses on the physical and biocompatibility performance of a medical device, not on the effectiveness of human readers assisted by 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 performed. This device is a physical catheter, not an AI algorithm.

7. The type of ground truth used

For the performance and verification testing, the "ground truth" was established by recognized industry standards (ISO 10555-1, ISO 10555-2, ISO 10993 series, ASTM F756, ASTM F2382, USP , USP 788) and internal protocols based on these standards. These standards define the acceptable physical properties, biocompatibility, and safety parameters for such devices.

8. The sample size for the training set

This information is not applicable as this study does not involve machine learning or 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 mentioned or implied in this type of device submission.
