The summary describes a physical medical device (vascular plug) and its mechanical and biological performance. There is no mention of software, algorithms, image processing, or any terms related to AI/ML.

Yes

The device is indicated to obstruct or reduce the rate of blood flow in the peripheral vasculature, which is a therapeutic intervention for a medical condition.

No

The device is an embolization device used to obstruct or reduce blood flow, which is a therapeutic function, not a diagnostic one.

No

The device description clearly outlines physical components including an implant assembly (gold implant body, silicone valves, platinum marker band, stainless-steel housing) and a delivery system assembly (microcatheter, delivery catheter, RHV, 3-way stopcock). The performance studies also detail bench testing of these physical components.

Based on the provided information, the Solus Gold Embolization Device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to "obstruct or reduce the rate of blood flow in the peripheral vasculature." This is a therapeutic intervention performed in vivo (within the body), not a diagnostic test performed in vitro (outside the body) on biological samples.
  • Device Description: The device is a vascular plug designed to be implanted in blood vessels. This is consistent with a therapeutic device, not a diagnostic one.
  • Lack of IVD Characteristics: The description does not mention any components or functions related to analyzing biological samples (blood, urine, tissue, etc.) to diagnose a condition or provide information about a patient's health status.

Therefore, the Solus Gold Embolization Device is a therapeutic medical device, not an In Vitro Diagnostic device.

Critical tasks were assessed through observation during simulated use and through user knowledge assessments about the device's labeling and procedure steps that were not amendable to simulated use testing. Additionally, the test subjects completed a survey. The human factors assessment demonstrated that the device labeling and training provided to the intended users allowed for the proper use of the Solus Gold Embolization Device in its intended use environment. Further, this assessment confirmed that all identified risks were considered acceptable and that no new risks were identified.

Pre-Clinical Animal Performance Testing

The Solus Gold Embolization Device and the MVP predicate device were evaluated in a chronic 90-day canine animal study model. Specifically, safety, effectiveness, in vivo performance and handling were conducted to assess device performance with the design requirements and product specification. Additionally, in vivo thrombosis testing (thrombogenicity) was conducted as part of the GLP animal study. The study was conducted under Good Laboratory Practice (GLP) controls pursuant to 21 CFR §58. The study complied with the requirements of Vascular and Neurovascular Embolization Devices - Class II Special Controls Guidance Document for Industry and FDA Staff (Dec. 2004), EN ISO 10993-4:2017 Biological Evaluation of Medical Devices Part 4: Selection of Test for Interactions with Blood and FDA General Considerations for Animal Studies for Cardiovascular Devices – Guidance for Industry and FDA Staff (July 2010). A total of seven (7) canine underwent treatment procedures with the Solus Gold Embolization Device and/or the MVP predicate device (Day 0). One Solus Gold Embolization Device (2.5 mm to 6.0 mm with 0.5 mm increments) or the MVP predicate device (MVP-3Q, MVP-5Q, MVP-7Q devices) was placed per treated artery (internal thoracic artery, renal artery, external iliac artery, and splenic artery. Follow-up angiography occurred on Day 28 ± 3 days after the treatment procedure. Terminal procedures took place on Day 90 ± 7 days. Acute embolization effectiveness was assessed by the time to achieve complete (Grade 0 or Grade 1) target vessel segment occlusion by angiography on Day 0. Chronic embolization effectiveness (durability) was assessed by target vessel segment occlusion by angiography (Grade 0 – 4) and morphometric percent vessel lumen occlusion by histology on Day 90.

The mean time to achieve complete (Grade 0 or Grade 1) target vessel segment occlusion by angiography on Day 0 was .50 minute for the Solus Gold Embolization Device and 1.94 minutes for the MVP predicate device. Complete (Grade 0 or Grade 1) target vessel segment occlusion was observed at 90 days were 14/14 for the Solus Gold Embolization Device and 2/14 for the MVP predicate device. Mean (maximal) percent vessel lumen occlusion by histology at 90 days was 100% for the Solus Gold Embolization Device and 79.6 % for the MVP predicate device. No complications were observed for either the Solus Gold Embolization Device or the MVP predicate device.
