The device description and performance studies focus on the mechanical properties and biological response to the implant, with no mention of AI or ML in the provided text.
Yes
The Medusa™ Vascular Plug is intended for arterial and venous embolizations, which are medical procedures to block blood vessels for therapeutic purposes, such as stopping bleeding or reducing blood flow to a tumor.
No
This device is an embolization device designed to occlude blood vessels, not to diagnose a condition. It is a therapeutic device used for treatment.
No
The device description explicitly states it consists of an implant and a delivery system, which are physical components, not software.
Based on the provided information, the Medusa™ Vascular Plug is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states it's for "arterial and venous embolizations in the peripheral vasculature." This is a therapeutic procedure performed in vivo (within the body) to block blood vessels.
- Device Description: The description details a "coil-based occlusion device" that is implanted to cause mechanical flow restriction and thrombus formation. This is a physical intervention within the body.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. The Medusa™ Vascular Plug does not perform any such testing.
The Medusa™ Vascular Plug is a medical device used for a therapeutic intervention, not for diagnostic testing of samples outside the body.

Intended Use / Indications for Use
The Medusa™ Vascular Plug is intended for arterial and venous embolizations in the peripheral vasculature. The product is intended for use by physicians trained and experienced in embolization techniques. Standard techniques for placement of vascular access sheaths, angiographic catheters, and guide wires should be employed.

Device Description
The Medusa™ Vascular Plug is a coil-based occlusion device intended for embolization procedures in the peripheral vasculature. The Medusa™ Vascular Plug consists of an implant and a delivery system. The implant is constructed of multiple polymer coils that are pre-loaded on to the delivery system. The Medusa™ Vascular Plug coils are delivered concurrently for vascular occlusion in a single application. Like predicate embolic coils, vascular occlusion with the Medusa™ Vascular Plug is achieved by mechanical flow restriction resulting from coil pack delivery that leads to thrombus formation and rapid cessation of blood flow.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical (bench and animal) testing was conducted.
- Design verification and bench validation studies
- In-vivo animal validation study
- Biocompatibility
- Sterilization
- Packaging and shelf-life
Animal Testing:
Study Type: In-vivo animal testing, direct comparison conducted in accordance with Good Laboratory Practices (GLP).
Sample Size: Not explicitly stated, but performed in an ovine model. Animals were sacrificed at 33 and 95 days post-implantation.
Key Results: The Medusa™ Vascular Plug exhibited performance equivalent to the predicate Cook stainless steel embolization coils through the 95-day time point, resulting in comparable stability of occlusion, comparable occlusion times, and comparable or better durability of occlusion. No acute or chronic complications were observed, and it was shown to be as safe as the predicate coils.

(a)
Identification. A vascular embolization device is an intravascular implant intended to control hemorrhaging due to aneurysms, certain types of tumors (e.g., nephroma, hepatoma, uterine fibroids), and arteriovenous malformations. This does not include cyanoacrylates and other embolic agents, which act by polymerization or precipitation. Embolization devices used in neurovascular applications are also not included in this classification, see § 882.5950 of this chapter.(b)
Classification. Class II (special controls.) The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance Document: Vascular and Neurovascular Embolization Devices.” For availability of this guidance document, see § 870.1(e).

INDICATIONS FOR USE
The Medusa™ Vascular Plug is intended for arterial and venous embolizations in the peripheral vasculature. The product is intended for use by physicians trained and experienced in embolization techniques. Standard techniques for placement of vascular access sheaths, angiographic catheters, and guide wires should be employed.
DEVICE DESCRIPTION
The Medusa™ Vascular Plug is a coil-based occlusion device intended for embolization procedures in the peripheral vasculature. The Medusa™ Vascular Plug consists of an implant and a delivery system. The implant is constructed of multiple polymer coils that are pre-loaded on to the delivery system. The Medusa™ Vascular Plug coils are delivered concurrently for vascular occlusion in a single application. Like predicate embolic coils, vascular occlusion with the Medusa™ Vascular Plug is achieved by mechanical flow restriction resulting from coil pack delivery that leads to thrombus formation and rapid cessation of blood flow.
SUBSTANTIAL EQUIVALENCE
The Medusa™ Vascular Plug and the predicate devices, the Cook Coils and the Amplatzer, have the same intended use and use similar technological characteristics to achieve the same mechanism of action. Any technological characteristics that are unique to the Medusa™ Vascular Plug have been validated to raise no new issues of safety or effectiveness. Therefore, the Medusa™ Vascular Plug is substantially equivalent to the Cook Coils and the Amplatzer.
NONCLINICAL TESTING IN SUPPORT OF SUBSTANTIAL EQUIVALENCE DETERMINATION
All necessary performance testing was conducted on the Medusa™ Vascular Plug to support a determination of substantial equivalence to the predicate devices. The non-clinical, bench and animal testing included:
- Design verification and bench validation studies .
- In-vivo animal validation studv ●
- Biocompatibility .
- Sterilization .
- o Packaging and shelf-life
The collective results of the non-clinical testing demonstrate that the Medusa™ Vascular Plug meets the established specifications necessary for consistent performance for its intended use.
ANIMAL TESTING IN SUPPORT OF SUBSTANTIAL EQUIVALENCE DETERMINATION
In-vivo animal testing was conducted to demonstrate that the Medusa™ Vascular Plug exhibits substantially equivalent occlusion performance in a clinically relevant model. A direct comparison was conducted in accordance with Good Laboratory Practices (GLP) in an ovine model to provide a direct comparison of the Medusa™ Vascular Plug and the Cook

Coils. Animals were sacrificed at 33 and 95 days post-implantation. At these time points, test subjects underwent angiographic assessment of stability and durability of occlusion (occlusion assessed by the physician), followed by euthanasia, gross necropsy, microscopic examination, and histopathology.
The Medusa™ Vascular Plug exhibited performance equivalent to the predicate Cook stainless steel embolization coils through the 95-day time point, resulting in comparable stability of occlusion, comparable occlusion times, and comparable or better durability of occlusion. At the same time, the Medusa™ Vascular Plug did not exhibit any acute or chronic complications, or raise any other questions of safety, demonstrating that it is as safe as the predicate coils. The Medusa™ Vascular Plug was shown to be substantially equivalent to the predicate coils in this chronic study and the results support a substantially equivalent determination.
CONCLUSION
The results of the nonclinical testing demonstrate that the new technological characteristics employed by the Medusa™ Vascular Plug do not raise any new issues of safety or effectiveness. Therefore, the Medusa™ Vascular Plug is substantially equivalent to the predicate devices.
