Yes
The device is used to provide a vacuum source for surgical procedures, including vacuum extraction, aspiration, and removal of surgical fluids and tissue. These functions are therapeutic as they are directly involved in treating or managing a patient's condition during surgery or at the bedside.
No
This device is a suction pump designed for providing a vacuum source and removing fluids, tissue, and other materials during surgery or at the bedside. It is an operative or therapeutic device, not a diagnostic one.
No
The device description clearly outlines physical components like a piston and cylinder system, vacuum gauge, vacuum regulator knob, operating elements, and a Safety Set, indicating it is a hardware device with integrated software (microcontroller).
Based on the provided text, the Medela Basic and Dominant Flex Suction Pumps are not IVD (In Vitro Diagnostic) devices.
Here's why:
- Intended Use: The intended use clearly states the pumps are for providing a vacuum source during surgery for procedures like vacuum extraction, aspiration of fluids and tissue, and use with surgical tools like cardiac tissue stabilizers and ablation probes. These are all procedures performed on the patient, not on samples from the patient for diagnostic purposes.
- Device Description: The description focuses on the mechanical function of the pump (providing vacuum and flow) and its features for surgical use (vacuum regulation, safety features, portability). There is no mention of analyzing biological samples or providing diagnostic information.
- Lack of IVD Characteristics: IVD devices are typically used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Medela suction pumps are used to remove these materials from the body during a procedure, not to analyze them for diagnostic purposes.
Therefore, the Medela Basic and Dominant Flex Suction Pumps are surgical devices, not IVD devices.

INTENDED USE:
The intended use for Medela's Basic and Dominant Flex Suction Pumps is to provide a vacuum source for use during surgery.
INDICATIONS FOR USE:
The Basic Suction Pump is indicated for vacuum extraction, aspiration during flexible endoscopy, and aspiration and removal of surgical fluids, tissue (including bone), gases, bodily fluids or infectious materials from wounds or from a patient's airway or respiratory support system either during surgery or at the bedside. The Basic Pump can also be used to provide the vacuum required for use with cardiac tissue stabilizers used in off-pump coronary artery bypass and for use with epicardial ablation probes.

The Dominant Flex Pump can also be used to provide the vacuum required for use with cardiac tissue stabilizers used in off-pump coronary artery bypass and for use with epicardial ablation probes.
DETERMINATION OF SUBSTANTIAL EQUIVALENCE:
SUMMARY OF TECHNOLOGICAL CHARACTERISTICS OF THE DEVICE COMPARED TO THE PREDICATE DEVICE
The labeling of the Basic and Dominant Flex has been revised to include the following new indications: aesthetic body contouring (Dominant Flex only) and to provide the vacuum required for use with cardiac tissue stabilizers used in off-pump coronary artery bypass and for use with epicardial ablation probes. The Basic and Dominant Flex Suction Pumps are compared to the previously cleared versions (K130123, main predicate) as well as to the Medela Dominant 50 for aesthetic body contouring (K063336), the Estech Cobra Surgical Systems for the new indication to provide a vacuum source during epicardial ablation (K051749) and the Medtronic Octopus Evolution AS 2010 and Urcin Evo 2020 Tissue Stabilizers (Class 1) to provide vacuum during off-pump coronary artery bypass.
The Basic and Dominant Flex only are providing a vacuum source that is used with ablation probes such asthe Estech System and with cardiac tissue stabilizers such as the Medtronic

stabilizers. The ablation probes and stabilizers do not provide vacuum, but the labelling, specifies the use of an operating room suction source.
The Dominant Flex has equivalent specifications to the Dominant 50 Lipo (K063336) for the aesthetic body contouring indication. The Dominant Flex operates at 0.16 horsepower (hp) which provides equivalent performance to the Dominant 50 Lipo which operates at 0.2 hp.
The Basic and Dominant Flex Suction Pumps use identical technology as the Basic and Dominant Flex Suction Pumps cleared in K130123.
SUMMARY OF NON-CLINICAL TESTS:
The Basic and Dominant Flex Suction pumps comply with voluntary standards for electrical safety, electromagnetic compatibility, and safety of electrically powered suction pumps. The changes to the product labeling for new indications for use did not impact compliance to standards as compared to the pumps cleared in K130123. Non-significant changes made to the Basic and Dominant Flex Suction Pumps since the original clearance were also described. One of these changes affected electromagnetic compatibility and therefore testing to IEC 60601-1-2:2007 was completed.
For the new indications for the Basic and Dominant Flex Suction Pumps, Medela AG has completed bench testing to demonstrate the performance of the pumps in the new applications.
For use for the indication of aesthetic body contouring, a comparison was made between the predicate Dominant 50 Lipo (cleared for aesthetic body contouring (K063336)) with the Dominant Flex to show their equivalence. Then the Dominant Flex was also compared to the HK Liposuction Aspirator Model AP-III which is also cleared for the indication of aesthetic body contouring (K032802). Testing showed equivalent free air flow, vacuum build up, and suctioning capacity of fluids with varying consistencies, including with various cannulas. The density of body fat varies due to the area suctioned and the technique. Sterile water, apple sauce and solidifier mix were used in the testing.
Testing was performed to demonstrate the compatibility of Basic and Dominant Flex in combination with epicardial ablation probes. Testing was conducted with the Estech Cobra Fusion Ablation System (bipolar or monopolar) and demonstrated that when the pump is running the vacuum is maintained at -600 mmHg ± 10%.
Testing was performed to demonstrate the compatibility of Basic and Dominant Flex in combination with cardiac tissue stabilizers used in off-pump coronary artery bypass (OPCAB). Testing was conducted with the Medtronic Octopus Evolution and Urchin Evo Positioners. The test results demonstrate that when the pump is running, the vacuum is maintained at settings of -250 or -400 mmHg for up to 8 hours.

Medela AG Basic and Dominant Flex Suction Pumps
SUMMARY OF CLINICAL TESTS:
The Basic and Dominant Flex Suction Pumps have not been the subject of clinical testing.
CONCLUSION:
The new indications for use do not change the intended use of the pump, to provide a vacuum source for use during surgery, and do not raise new issues of safety and effectiveness as compared to the main predicate device, cleared in K130123. 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 Basic and Dominant Flex are substantially equivalent to the legally marketed predicate device.
