The subject devices (Penumbra Coil System and POD System) are designed for embolization in the neuro and/or peripheral vasculature. This is achieved by using coils to exclude the intended treatment area from blood flow, thus creating stasis and allowing thrombosis to occur. The subject devices consist of a bare platinum embolization coil for the treatment of aneurysms or other vascular abnormalities. The devices should only be used by physicians who have received appropriate training in interventional techniques.
The subject devices consist of the following components:
- Coil: The Coil is attached to a Delivery Pusher both contained within an Introducer Sheath. The Coil is an implantable medical device intended to exclude the treatment area from blood flow, thus creating stasis and allowing thrombosis to occur.
- Delivery Pusher: The Delivery Pusher is composed of a shaft with a radiopaque positioning marker, a Distal Detachment Tip (DDT) and a pull wire. The Delivery Pusher may also be referred to as the Detachment Pusher.
- Introducer Sheath: The Introducer Sheath is intended to cover the entire length of the Coil and the distal flexible segment of the Delivery Pusher. The Introducer Sheath is secured onto the Delivery Pusher with a friction lock to prevent unsheathing until use.
- Detachment Handle: The Detachment Handle is packaged separately. It is intended for use in multiple coil detachments performed during a single procedure.
This document, a 510(k) Premarket Notification for the Penumbra Coil System and POD System, focuses on demonstrating substantial equivalence to a predicate device rather than presenting a study proving a device meets specific acceptance criteria for performance, especially concerning Artificial Intelligence (AI) or software-based diagnostics.

-
Sample sizes used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective):
- N/A. This is a physical device, and the "test set" here refers to the number of units or biological samples used in bench-top and biocompatibility testing, not a clinical data set for an AI model. The document does not specify the number of units tested for each bench-top criterion. Biocompatibility tests followed ISO and CFR guidelines.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience):
- N/A. Ground truth establishment by experts is relevant for AI/diagnostic software. For a physical device, ground truth is established by objective measurements against engineering specifications and biological material reactions.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- N/A. Adjudication is for resolving discrepancies in expert interpretations, not for physical device testing.
-
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:
- N/A. This applies to AI-assisted diagnostic tools, not physical embolization coils.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- N/A. This applies to AI/software.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For this device, "ground truth" related to performance is based on engineering specifications, direct physical measurements, and well-established biological response criteria (e.g., cell viability, immune response markers) in a laboratory setting, as well as adherence to recognized standards like ASTM and ISO. There is no "expert consensus" on ground truth for the physical and biological properties being tested here in the way there would be for a diagnostic image.
-
The sample size for the training set:
- N/A. There is no "training set" as this is not an AI/machine learning device.
-
How the ground truth for the training set was established:
- N/A. There is no "training set" or AI model.

12.2. MR Compatibility Testing
Testing in 1.5T & 3T MR environment was performed to advise the MR conditional statement in the Instructions for Use (IFU). Testing was done in accordance to standards ASTM F2182-11, ASTM F2052-15, ASTM F2213-06 (R-11), and ASTM F2119-07 (R-13).
12.3. MRA Testing
MRA artifact associated with a Penumbra coil array in the form of an 8 mm diameter sphere was assessed per ASTM F2119-07 (R-13) using a clinical MRA sequence. The maximum artifact distance beyond the implant was 2 mm using this sequence.
13. Summary of Substantial Equivalence
The subject Penumbra Coil System (i.e., Penumbra Coil 400 and Ruby Coil System) and POD System are substantially equivalent to the predicate device Penumbra Coil System. The subject devices have identical intended use as the predicate device. The subject and the predicate devices differ slightly in regards to minor technological variations, while maintaining the same fundamental scientific technology. However, these differences do not raise different questions of safety and effectiveness.
The device testing described in the 510(k) Summary demonstrate the subject devices are substantially equivalent to the predicate device in regards to operating principle, fundamental technology and device performance.

Identification. A neurovascular embolization device is an intravascular implant intended to permanently occlude blood flow to cerebral aneurysms and cerebral ateriovenous malformations. This does not include cyanoacrylates and other embolic agents, which act by polymerization or precipitation. Embolization devices used in other vascular applications are also not included in this classification, see § 870.3300.(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 § 882.1(e).
