Indications for Use
The Medela Vario 8/18/ci Suction Pumps are indicated for aspiration and removal of surgical fluids, tissue (including bone), gases, bodily fluids (including vomit) or infectious materials from a patient's airway or respiratory support system, either during surgery or at the patient's bedside. Generally the Medela Vario 8/18/ci is intended to be used for a variety of suctioning procedures including nasopharyngeal, tracheal, surgical, gastrointestinal in either "constant" or "intermittent" mode.
Device Story
Vario 8/18/ci is an AC or AC/DC-powered suction pump; utilizes QuatroFlex™ technology with motor, flat belt transmission, and four piston/cylinder modules to generate vacuum. Device features include vacuum gauge, membrane vacuum regulator, and hydrophobic filter for overflow protection. Used in professional healthcare facilities by clinicians for aspiration of fluids/tissues/gases. Operator adjusts suction via mechanical regulator knob; vacuum level monitored via analog gauge. Output is suction force; aids in clearing airways or surgical sites. Benefits include rapid vacuum buildup and portability. AC/DC models include basic firmware for motor control and battery management.
Clinical Evidence
No clinical data. Substantial equivalence demonstrated via non-clinical bench testing, including risk analysis (ISO 14971), software verification/validation, electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), and performance testing (EN ISO 10079-1) for vacuum/flow, battery runtime, and sound emissions.

# SUMMARY OF NON-CLINICAL TESTS:
The Vario 8/18/ci suction pump complies with voluntary standards for electrical safety, electromagnetic compatibility, and powered suction pumps. The following data were provided in support of the substantial equivalence determination:
- . Risk Analysis developed in accordance with ISO 14971: 2007.
- . Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern, since prior to mitigations of hazards, failure of the software could lead to minor injury, such as pain or engorgement.
- . Electrical safety and electromagnetic compatibility testing per IEC 60601-1:2005 (3rd Edition) with US deviations per AAMI/ANSI ES60601-1:2005 standard and IEC 60601-1-2: 2007 standards, respectively
- . Performance testing demonstrating compliance with EN ISO 10079-1: 2009 Particular requirements for the safety of electrically powered suction equipment
{10}------------------------------------------------
- . Vacuum and flow measurements: Performance testing to determine the vacuum levels and flow of the pump as compared to its specifications, which are identical to those of the predicate version of the Vario 8/18/ci pumps.
- . Verification of operating times of the Vario AC/DC, if it is powered by battery only. The operating times were checked with different pump loads and battery types. The correct function of the battery low indication was also confirmed. The function is dependent on the antecedent pump settings / work load. The dependency was checked at worst case conditions, therefore completely different pump loads/settings were chosen for each test run. Verification of the reliability of the charging/discharging process in different ambient temperatures was also completed.
- . Confirmation of the endurance runtime of the Vario AC/DC is at least the specified 2,600h.
- . Confirmation that the sound emission of the pumps is below the maximum specification.
# SUMMARY OF CLINICAL TESTS:
Clinical testing was not required to demonstrate the substantial equivalence of the Vario 8/18/ci suction pump to its predicate device.
# CONCLUSION:
The differences between the Vario 8/18/ci suction pumps and its predicate device do not introduce a new intended use and do not raise new issues of safety and effectiveness. Verification and Validation testing demonstrated that no adverse effects have been introduced by these differences and that the device performs as intended.
From the results of nonclinical testing described, Medela AG concludes that the Vario 8/18/ci suction pumps are substantially equivalent to the legally marketed predicate device.
