InstaClear Lens Cleaner
Intended to clear the end of a rigid rod endoscope in order to maintain clear visualization of endoscopic procedures without having to remove the scope from the surgical site.
The device is indicated for use during routine diagnostic procedures and during endoscopic sinus surgery.
The InstaClear Lens Cleaner system is equivalent to the predicate device cleared under K982594. The system includes a reusable AC powered console with pump, a reusable footpedal, and sterile disposable single-use accessories.
The system is used to clear the end of a rigid endoscope in order to maintain clear visualization of endoscopic procedures without having to remove the scope from the surgical site. The device is indicated for use during routine diagnostic procedures and during endoscopic sinus surgery (ESS).
The system accessories include sterile sheaths to fit various sizes of 4mm Olympus and Storz endoscopes, a sterile irrigation tubeset, and a non-sterile footpedal. The console includes software to control irrigation delivery and suction.
This document describes the InstaClear Lens Cleaner device and its performance testing to support its substantial equivalence to a predicate device.

2. Sample Size Used for the Test Set and the Data Provenance
The document does not explicitly state the specific sample sizes used for each performance test. It refers to "representative samples" for stability and environmental testing.
- Data Provenance: The studies were non-clinical (electrical, mechanical, functional) performance testing and preclinical (bench) evaluations and testing. These are laboratory-based tests, not human trials.
- Country of Origin: Not specified, but conducted by Gyrus ACMI, Inc. a US-based company with manufacturing in Bartlett, TN, USA.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not applicable. This device's performance was evaluated through non-clinical and preclinical bench testing against objective criteria and comparison to a predicate device, not through expert-reviewed clinical data or human studies.
4. Adjudication Method for the Test Set
Not applicable. As described above, the testing involved objective performance metrics and comparison to a predicate device, not expert adjudication of human subject results.
5. 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
Not applicable. This device is a lens cleaner, not an AI-powered diagnostic or interpretive tool that would involve human readers.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a physical medical device, not a software algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for the non-clinical and preclinical performance tests was based on:
- Objective Engineering Specifications: For electrical safety, EMC, burst pressure, torque strength, etc.
- Established Sterilization Standards: For sterility assurance level.
- Simulated Use Conditions with Analogs: For cleaning performance (using a blood analog).
- Performance Characteristics of the Predicate Device: For comparative evaluation of features like cleaning cycle time, clearing performance, and leak/drip rate.
8. The Sample Size for the Training Set
Not applicable. This document describes a physical medical device, not a machine learning or AI model that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.
