The summary describes a manual aspiration system and its mechanical compatibility and performance, with no mention of AI or ML.
Yes
This device is used for controlled aspiration of blood and other components, which is a direct medical intervention aimed at treating medical conditions. Therefore, it is a therapeutic device.
No
The device is an aspiration system used for controlled removal of various fluids and tissues from the brain during surgery, not for diagnosing conditions.
No
The device description explicitly lists physical components (device guide, guide sheath, stylet, depth stops, cannula, adapter) and describes testing related to their physical properties and performance (flow, leak, aspiration, compatibility with hardware). There is no mention of software as the primary or sole component.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body outside of the body to provide information for diagnosis, monitoring, or screening.
- Device Function: The MR Compatible Aspiration System is used during surgery to remove fluids and tissues directly from the patient's body (Ventricle System or Cerebrum) using a manual syringe. It is a surgical tool for aspiration, not a device for analyzing samples in a lab setting.
The description clearly indicates its use as a surgical accessory for aspiration during image-guided procedures, which falls outside the scope of IVD devices.

Device Description
The MCA Kit is an accessory to the cleared ClearPoint System (K171257). The MCA Kit consists of a MCA device guide, guide sheath, stylet, depth stops, cannula (with attached tube) and adapter. The MCA Kit is designed to aid a physician in the removal of specific tissue or fluid types from the brain during image guided surgery. It is MR safe, as all materials are non-metallic. The MCA Kit is comprised of single use only, sterile-packaged disposable components that are packaged together.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Bench testing was performed to verify the MCA Kit's compatibility with the ClearPoint System, accuracy, and substantial equivalence to the predicate aspiration device.
Accuracy Testing: The company used the same ground truth procedure and test methods that were used in the accuracy testing provided in support of K142505 and K171257 for the ClearPoint System. The test set-up utilized only the scalp mount bases and SmartFrame XG, since the MCA Kit must be used with the SmartFrame XG to allow device guide insertion, and the scalp mount base is the most likely configuration to be used clinically. Placements were performed using the 12 Fr x 30 cm and 16 Fr x 30 cm MCA Kits, which represent the smallest and largest OD sizes; accordingly, the test results support the performance of all sizes of the MCA kit. Target depth was 125 mm from the base-mounting surface for all placements. Results from the company's bench accuracy tests demonstrated that the mean error was below 1.0mm, with the highest standard deviation being 0.75mm in the X direction and highest 99% upper confidence limit of 1.48mm in the X direction. The mean angular error was below 1°, with a standard deviation of 0.34° and 99% upper confidence limit of 0.72°. These values are below the 2mm and 2° accuracy limits for a stereotaxic device intended for general neurological use.
MCA-Kit Device Guide–SmartFrame XG Compatibility: Performance testing was completed to verify that the device guide and SmartFrame XG are compatible per pre-defined acceptance criteria. Testing included insertion and retention of the Device Guide and Adapter to the SmartFrame under tensile and torque loading, stability of the Guide Sheath-Stylet and Guide Sheath-Cannula under lateral loading when inserted in the SmartFrame, and accuracy with the SmartFrame. All acceptance criteria were met to demonstrate that the MCA Kit components are compatible with the cleared ClearPoint System SmartFrame XG.
Flow and Leak Testing: Testing was conducted to confirm that the device could aspirate at least 10cc of various materials simulating blood, clotted blood, cystic components of tumors, abcesses, colloid cysts, and cerebrospinal fluid without leaking or collapsing and at an acceptable flow rate. The tests demonstrated that the MCA Kit functions as intended and is substantially equivalent to the legally marketed predicate.
Aspiration Test: Testing was performed to confirm the device remains operable for a limited period of time at 29.0 inHg for the MCA Kit Cannulas Twelve Fr. and 16 Fr. Cannulas that have undergone worst-case conditioning were used for this test. Plugged cannulas were evaluated under high vacuum generated by a pump to create worst-case conditions. The change in device inner diameter (I.D.) was measured to confirm that the device's integrity was maintained during the aspiration. The device was also verified to remain undamaged after exposure to the conditions. All Cannulas tested were able to withstand collapsing, leaking, or failing in any other manner when experiencing a minimum aspiration pressure of 29.0 inHg. The measured change in the Rigid section I.D. of the Cannulas was 0.0% for the 12 Fr., and 0.8% for the 16 Fr. The flexible Tubing had a measured change in I.D. of 1.3% for the 12 Fr. and 2.9% for the 16 Fr. Cannulas. The device can operate for a limited period of time at an aspiration pressure of 29.0 inHg without failing.

The MCA Kit and Apollo System have substantially similar intended use and indications for use, as well as similar technological characteristics. The minor technological differences in the MCA Kit compared to the Apollo System do not raise new questions of safety or effectiveness. The MCA Kit's accuracy, compatibility with the ClearPoint System SmartFrame XG, flow, leak, and aspiration testing further confirm that the device performs as intended and is substantially equivalent to the legally marketed predicate.
