Endoscopic Irrigation/Suction System (OCX) — FDA decisions, comparisons and evidence
The 2021–2025 analysis contains 24 selected substantially-equivalent FDA decisions under primary product code OCX. Use it to compare documented submissions and evidence with your product. A separate 2026 update contains 0 decisions through 2026-09-27. The latest selected decision across the acquired endpoint is dated 2025-09-26. Neither set establishes a suitable predicate or the route for your device. The complete-year window has 24 decisions; the separate all-observed-date count is 93. These denominators describe different date ranges.
Evidence retrieved 2026-10-06. Source versions and topic-specific limits are listed below.
Historical FDA comparison
2021–2025: five complete calendar years
All statistics in this section use decisions dated 2021-01-01 to 2025-12-31. The partial 2026 update below is excluded from these distributions.

24Valid date pairs in the distribution
The middle 50% of the 24 valid date pairs spans 81.2–217.2 calendar days. This describes selected recorded submissions, including elapsed time outside active FDA review. It is not an FDA review-time measure or a delivery promise.

Filters, exclusions and reproducible calculation
Deduplicate by official submission ID across the complete current manifest partitions. Select exact primary product code, K-number format and the stated SE decision codes with valid dates. Recent distributions use the five complete calendar years preceding the latest valid endpoint decision year. Partial-year counts compare equal January-to-cutoff periods. Quartiles use linear interpolation at (n-1)*p and are withheld below 20 valid date pairs. The analysis n describes only its declared complete-year window; selected_se_n separately counts all selected recorded dates through the cutoff.
93 selected records across all observed dates; 0 other/invalid identifier or decision-date records excluded. 0 missing or invalid date pairs in the five-year window.
Date fields: date_received → decision_date. Quantiles: Hyndman–Fan type 7: linear interpolation at (n − 1) × p; displayed to one decimal; n ≥ 20 valid pairs.
Receipt-to-decision calendar elapsed time includes time outside active FDA review; it is not FDA review time, a promised project timeline or an estimate of future clearance. This selected recorded cohort does not include all applications or establish a success probability, predicate suitability, market size, current market availability or legal authorization for another product.

Separate partial-year update
2026 decisions through 2026-09-27
0 selected decisions from 2026-01-01 to 2026-09-27. The equivalent previous-year period contains 4 decisions through 2025-09-27. These counts describe the records; they are not market growth or submission success rates.

Latest decisions across the database
These dated records may come from 2026 or earlier years. They are a separate investigation list, not the five-year statistical cohort. Compare the actual indications and technology before considering a record as a comparator.

Build a comparison that explains the differences
Use this checklist to gather your business or product details before speaking with a specialist. The items below explain what to record and suggest useful supporting documents. You can add your own answers in the editable project brief.
Compare your intended use with a named decision
Choose a named record above. Put your proposed claim beside its actual indications-for-use statement. Record different patients, users, anatomy, settings and output claims; do not treat a shared code as proof of equivalence.
Useful evidence: Your draft indications for use + the selected official summary and its exact page.
Explain the technology and evidence differences
For each comparison, record the different materials, hardware, software functions and operating conditions. Link each difference to existing evidence or an unresolved evaluation task.
Useful evidence: A three-column matrix: comparator fact / your design fact / evidence or unresolved gap.
Make the estimate comparable
Use the 2021–2025 cohort, and compare the recorded submission type before discussing calendar elapsed time. Separate your own preparation work from the recorded receipt-to-decision period.
Useful evidence: Chosen K numbers, submission types, dates and your own document/test readiness.

Questions for providers
- Which of the named OCX decisions are actually comparable to our proposed indications and technology, and which would you exclude?
- Which evidence differences prevent us from using the comparison yet, and what deliverable resolves each one?
- Does your schedule separate submission preparation, testing, FDA interactions and customer response time? What assumptions change it?
