The device description and performance studies focus on the physical attributes and mechanical performance of a delivery catheter, with no mention of AI or ML capabilities.
No
This device is a delivery catheter intended to assist in the delivery of other interventional devices; it does not itself provide a therapeutic effect.
No
Explanation: The device is a delivery catheter intended to assist in the delivery of interventional devices, not to diagnose a condition. Its function is to facilitate access and navigation within the neurovasculature for other devices.
No
The device description clearly outlines a physical catheter with specific material properties, dimensions, and a hydrophilic coating, indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "assist in the delivery of interventional devices... in the neurovasculature." This describes a device used within the body for a therapeutic or procedural purpose, not a device used to examine specimens outside the body to diagnose a condition.
- Device Description: The description details a catheter designed for navigating blood vessels, delivering other devices, and being visualized under fluoroscopy. This aligns with an interventional medical device, not an IVD.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information based on in vitro testing.
IVD devices are specifically designed to be used in vitro (outside the living body) for the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device clearly operates in vivo (within the living body).

Device Description
The Wedge XL Delivery Catheter is a single lumen catheter designed to be introduced over a steerable quidewire to access small, tortuous vasculature. The semi-rigid proximal section transitions to a flexible distal tip to facilitate advancement through vessels. Radiopaque markers at the distal end facilitate fluoroscopic visualization. A larger diameter distal segment helps provide stability for navigation. The distal 110 cm outer surface of the Wedge XL Delivery Catheter is coated with a hydrophilic polymer to increase lubricity. A luer fitting on the Wedge XL Delivery Catheter hub is used for the attachment of accessories.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance Testing - Bench: The following bench performance testing was performed to support the design of the Wedge XL Delivery Catheter and demonstrate that it performs as intended. All tests passed the pre-determined acceptance criteria: Physical Attributes, Surface Contamination, Coating Lubricity and Durability, Simulated Use (Preparation/Ease of Assembly, Introducer Sheath Insertion, Tracking With/Without Guidewire, Delivery Catheter/Guidewire Lock Up, Catheter Ovalization, Lubricity/Durability of Hydrophilic Coating, Guide Catheter Tracking over Wedge XL Delivery Catheter, Particle Testing), Dynamic Burst Pressure, Freedom from Air Leakage, Freedom from Liquid Leakage, Static Burst Pressure, Force at Break, Catheter Flexural Fatigue, Catheter Particle Testing, Kink Resistance, Torque Strength, Luer-Connector Dimensions and Performance Testing per ISO 80369-7. Radiopacity testing and corrosion resistance testing were previously conducted on a test article that was equivalent to the Wedge XL Delivery Catheter in all aspects relevant to the testing performed.
Biocompatibility Evaluation: Tested for Cytotoxicity, Sensitization, Irritation Reactivity, Material Mediated Pyrogenicity, Systemic Toxicity, Hemocompatibility (Hemolysis Assay - Extract and Direct Methods, Complement Activation Assay, Partial Thromboplastin Time (PTT) Test, Heparinized Blood Platelet and Leukocyte Count Assay, In-Vitro Blood Loop Assay). All tests showed acceptable results (Non-cytotoxic, Non-sensitizer, Non-irritant, Non-pyrogenic, No systemic toxicity, Non-hemolytic, Non-activator for complement activation, Non-activator for PTT, Non-activator for platelet and leukocyte count, Thromboresistant).
Animal Study: Acute, subacute, and chronic animal testing was conducted in accordance with Good Laboratory Practice (GLP) Regulation (21 CFR Part 58) comparing the Wedge XL Delivery Catheter to the predicate Wedge Microcatheter (K172014) in a porcine model. The study was designed to assess the safety and performance of catheter tracking. Animals were survived to subacute (3 days) and chronic (30 days) time points. The study results demonstrated that use of the subject Wedge XL Delivery Catheter with the SOFIA 88 Catheter (K214024) and Wedge Microcatheter with the SOFIA 6F Catheter (K172014, K150366) performed equally in all animal testing. No remarkable gross findings were observed during postmortem examination. Histological findings were consistent with routine catheterization procedures. The results did not raise any safety concerns, and the devices are deemed equivalent.

Animal Study
Acute, subacute, and chronic animal testing was conducted in accordance with Good Laboratory Practice (GLP) Regulation (21 CFR Part 58) comparing the Wedge XL Delivery Catheter to the predicate Wedge Microcatheter (K172014). The study was designed to assess the safety and performance of catheter tracking in a porcine model. The porcine model was chosen because the vessel sizes allow the insertion and navigation of standard-sized catheters used in humans. Animals were survived to subacute (3 days) and chronic (30 days) time points after procedures to evaluate the vascular response to device use. The study results demonstrated that use of the subject Wedge XL Delivery Catheter with the SOFIA 88 Catheter (K214024) and Wedge Microcatheter with the SOFIA 6F Catheter (K172014, K150366) performed equally in all animal testing. During postmortem examination there were no remarkable gross findings in any of the vessels evaluated with either test or control devices. There was a comparable histological impact of device use on arterial sections in which test and control devices were used. Artery sections subjected to the stiffest segment of the Wedge XL Delivery Catheter exhibited similar tissue responses as to control devices. Overall, the histologic findings were consistent with routine catheterization procedures, which are commonly observed after interventional procedures in porcine models. The results of the animal study did not raise any safety concerns with either the test Wedge XL Delivery Catheter or control Wedge Microcatheter. The devices are deemed equivalent.

Conclusion
MicroVention concludes based upon the comparison of the device intended use, indications for use, operating principles, technological characteristics, and the review of the performance bench testing, animal study assessments, sterility, and biocompatibility evaluation that the Wedge XL Delivery Catheter is substantially equivalent to the predicate Wedge Microcatheter and performs as intended. Any differences between the subject device and the predicate device do not raise new or different questions of safety and effectiveness.
