Advancing
Surgical Visualization

Pathway

510(k) Class II submission planned for FDA Surgery Division as a surgical nerve visualization aid.

Evidence Base

From laboratory validation to multi-site human feasibility studies.

Engineering Excellence

Alina™ Beta design integrating surgeon feedback into manufacturable clinical units.

Next Milestone

Clinical prototype and clinical study launch to support FDA clearance.

Live Technology Preview

Real-Time Live Thresholding

Live bench testing of the Alina™ system demonstrating the milestone of live-view thresholding of sciatic nerve tissue placed on spleen. A separate collagen structure is also visible in the field, helping show that the thresholding is selectively identifying nerve tissue rather than surrounding non-nerve structures.

This preview reflects YaYa Scientific’s continued progress in developing imaging tools designed to enhance tissue visualization and support future surgical applications.

Clinical Context

Why Alina™ Matters

Chronic postoperative pain and nerve injury remain significant challenges across many surgical specialties in the United States. Even when overall risk is low, the consequences of nerve damage can be profound—affecting sensation, motor function, recovery time, quality of life, and long-term healthcare costs.

YaYa Scientific focuses on generating data that supports safer, more confident surgery. In collaboration with leading academic medical centers, we are evaluating whether real-time, intraoperative nerve visualization can reduce preventable injury and improve patient outcomes—without disrupting existing surgical workflows.

Can it integrate seamlessly?

We study how the technology fits into standard operating room workflows—assessing usability and surgeon adoption in live cases without adding procedural complexity.

Does it inform decisions?

Studies examine whether real-time visualization enhances intraoperative awareness and helps surgeons identify, preserve, or repair nerves more confidently.

Does it improve outcomes?

Our multi-site clinical studies measure safety, performance, and patient-reported outcomes to quantify the benefit of nerve visualization during surgery.

Our goal: Build the clinical and scientific evidence needed to show that intraoperative nerve visualization improves safety, preserves function, and empowers surgeons to deliver better patient outcomes.
Regulatory Primer

What is a "510(k) - Class II" FDA Submission?

A 510(k) is an FDA premarket submission commonly used for Class II medical devices. It demonstrates that a new device is substantially equivalent to a legally marketed predicate device and meets the applicable requirements for safety and effectiveness. If FDA determines that the device is substantially equivalent, it grants 510(k) clearance, allowing the device to be commercially marketed in the United States.

When is 510(k) used?

  • The device is classified as Class II and is not exempt from 510(k) requirements.
  • A legally marketed predicate device can be identified.
  • The device has the same intended use as the predicate.
  • Any differences do not raise new safety or effectiveness concerns.
  • Testing can support substantial equivalence.

What does FDA expect?

  • Device description, indications, and technical details.
  • Comparison to a legally marketed predicate device.
  • Risk analysis and proposed mitigations.
  • Nonclinical testing — bench, software, biocompatibility, EMC.
  • Clinical evidence when needed to support claims.

What we must do:

  • Finalize Alina™ Beta design & manufacturing controls.
  • Confirm the predicate and regulatory strategy.
  • Complete bench and GLP safety testing.
  • Conduct clinical studies as needed.
  • Compile full 510(k) submission package.
  • Demonstrate a compliant QMS and documentation trail.

Typical Submission Process

  1. Pre-submission: Request FDA feedback.
  2. Complete testing & studies: Bench, GLP safety, clinical as needed.
  3. Submit 510(k): Include predicate comparison, risks, testing, and labeling.
  4. Interactive review: Respond to FDA questions.
  5. Decision: If substantially equivalent, the device receives FDA clearance.

Timelines vary with device complexity, required evidence, and FDA interactions.

How this fits our roadmap:

As YaYa Scientific progresses from Alina™ Beta verification and GLP safety testing to surgeon studies. This data — combined with risk analysis, predicate comparison, and manufacturing controls — will form the foundation of our 510(k) - Class II FDA submission.
