Negative Pressure Wound Therapy Powered Suction Pump (OMP) — FDA decisions, comparisons and evidence

The 2021–2025 analysis contains 41 selected substantially-equivalent FDA decisions under primary product code OMP. Use it to compare documented submissions and evidence with your product. A separate 2026 update contains 7 decisions through 2026-09-27. The latest selected decision across the acquired endpoint is dated 2026-09-11. Neither set establishes a suitable predicate or the route for your device. The complete-year window has 41 decisions; the separate all-observed-date count is 215. These denominators describe different date ranges.

Evidence retrieved 2026-10-07. Source versions and topic-specific limits are listed below.

Recorded scope and its declared regulatory reference

An exact FDA-record regulation_number match to one acquired Title 21 section. Records with the same normalized scope definition, class, regulation and recorded submission/GMP flags are grouped. Sparse definitions and generic exemption boilerplate do not qualify. No text-similarity equivalence or legal applicability is inferred.

What scope does the FDA record describe?

For wound management via application of continual or intermittent negative pressure to the wound for removal of fluids, including wound exudate, irrigation fluids, and infectious materials. The Device is indicated for management of chronic, acute, traumatic, subacute and dehisced wounds, partial-thickness burns, ulcers (such as diabetic or pressure), flaps and grafts.

Compare the proposed indication, user, anatomy, technology and operating principle with this actual scope; record differences and unresolved facts.

Cited source

Which current section does the record cite?

§ 878.4780 Powered suction pump. (a) Identification. A powered suction pump is a portable, AC-powered or compressed air-powered device intended to be used to remove infectious materials from wounds or fluids from a patient's airway or respiratory support system. The device may be used during surgery in the operating room or at the patient's bedside. The device may include a microbial filter. (b) Classification. Class II.

Read the identification, classification, conditions and referenced limitations in the cited section. A numeric reference match is not a buyer classification or exemption determination.

Historical FDA comparison

2021–2025: five complete calendar years

Primary code OMP

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.

The middle 50% of the 41 valid date pairs spans 136.0–351.0 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.

215 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

7 selected decisions from 2026-01-01 to 2026-09-27. The equivalent previous-year period contains 3 decisions through 2025-09-27. These counts describe the records; they are not market growth or submission success rates.

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.

  1. Which specific part of the recorded scope fits or differs?

    Put your proposed label and design beside the quoted definition. Record matching facts, differences and missing facts separately; naming the category alone cannot resolve scope.

    Useful evidence: Proposed indication/design and a definition-to-product comparison with source locators.

  2. Have the cited section and its limitations been reviewed?

    Record the applicable paragraph, conditions and cross-referenced limitations after specialist review. Keep a claimed exemption separate from actual establishment, listing and quality-system responsibilities.

    Useful evidence: Dated classification/route rationale and the current provisions relied on, with unresolved conditions.

  3. 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.

  4. 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.

  5. 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.
