The description focuses on a powered reciprocating cannula and its mechanical function, with no mention of AI or ML terms or capabilities.
No
The device is described as a surgical tool for tissue and fluid removal, assisting surgeons, rather than providing therapy or treatment itself.
No
The device is indicated for the removal of tissue or fluid during general surgical procedures, not for diagnosis.
No
The device description explicitly mentions a "powered reciprocating cannula" and describes laboratory tests involving aspiration and penetration force, indicating a physical hardware component.
Based on the provided information, the MicroAire PAD System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is "for the removal of tissue or fluid from the body during general surgical procedures." This describes a surgical tool used on the body, not a device used to test samples from the body in a laboratory setting.
- Device Description: The description details a powered surgical cannula for aspiration, focusing on its mechanical function and how it interacts with tissue and fluid within the body.
- Lack of IVD Characteristics: There is no mention of analyzing samples, detecting substances, diagnosing conditions based on biological samples, or any other activity typically associated with in vitro diagnostics.
IVD devices are used to examine specimens (like blood, urine, tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. The MicroAire PAD System is a surgical instrument used for removal of material during a procedure.

Device Description
The MicroAire® PAD™ System differs from the predicate devices in that it possesses a powered reciprocating cannula. The small (2-6 mm), rapid stroke of the PAD" cannula simulates the manual hand motion that the surgeon would use during aspiration with the predicate devices. Thus, use of the PAD" System does not raise safety and effectiveness issues that are significantly different from those of the predicate devices. At the same time, the powered cannula minimizes surgeon effort by reducing the amount of necessary arm motion. Furthermore, the slight reciprocating action of the PAD" System facilitates the passage of the cannula through tissue. When the reciprocating action is not activated by the surgeon, the PAD" device functions in an identical manner to the predicate devices.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Laboratory tests showed that the PAD" System was comparable to predicate devices for the purpose of aspiration. Physiological saline and a viscous wound cleansing solution were aspirated by the PAD" System and a standard suction cannula. The wound cleansing solution had a consistency similar to synovial fluid or mucus. The fluids were aspirated by a vacuum pressure of 20 cm Hg for ten seconds. The volume of aspirated fluid was measured several times for both tools. There were no significant differences between the aspiration rates of the PAD" System and the regular suction cannula. The reciprocating cannula did not affect the rate of aspiration.
Nonclinical evaluations of the PAD" device also demonstrated its advantage over the predicate devices. The force required to enter soft tissue with reciprocating and nonreciprocating cannulae was quantified using in vitro animal experiments. The results of these tests demonstrated that the reciprocating cannula reduced the magnitude of penetration force by approximately 70%.

MicroAire believes the PAD" System to be substantially equivalent in basic form and function to the following legally marketed devices:
The predicate devices are cannulae that are capable of being attached to a suction source. These devices are indicated for general aspiration of fluid or loose tissue. Both devices are essentially a closed, hollow steel tube with one or more openings at the tip. The cannulae are available in different lengths, diameter sizes, and tip configurations. They are connected to a suction source to create a negative pressure within the cannula. This negative pressure causes fluid and friable tissue to be suctioned into the cannula when it is inserted surgically. The surgeon is able to remove undesirable fluid and tissue accumulation by manually guiding the cannula through the treatment area.
The MicroAire® PAD™ System differs from the predicate devices in that it possesses a powered reciprocating cannula. The small (2-6 mm), rapid stroke of the PAD" cannula simulates the manual hand motion that the surgeon would use during aspiration with the predicate devices. Thus, use of the PAD" System does not raise safety and effectiveness issues that are significantly different from those of the predicate devices. At the same time, the powered cannula minimizes surgeon effort by

reducing the amount of necessary arm motion. Furthermore, the slight reciprocating action of the PAD" System facilitates the passage of the cannula through tissue. When the reciprocating action is not activated by the surgeon, the PAD" device functions in an identical manner to the predicate devices.

To ensure the safety of the MicroAire® PAD" System, the instruments comply with applicable standards. Sterility of the multiple-use PAD" instruments and power supply hoses can be achieved through the procedures detailed in AAMI's Good Hospital Practice-Steam Sterilization and Sterility Assurance. The disposable suction cannulae and tubing are pre-sterilized according to ANSI/AAMI/ISO 11137-1994, Sterilization of Health Care Products-Requirements for Validation and Routine Control-Radiation Sterilization. The MicroAire® 6025 electric console is designed to meet the electrical safety requirements of UL-544 and IEC-601-1. In addition, the components of the MicroAire® PAD" System are all comprised of materials with a long history of safety when incorporated in medical devices
