The Apollo System is used for the controlled aspiration of tissue and/or fluid during surgery of the Ventricular System or Cerebrum.

The Apollo System is designed to aid a physician in the removal of tissue and/or fluids during image-guided neurosurgery. The reusable components have three functions; vacuum generation, generation of vibrational energy, and saline irrigation. The disposable component, the Wand is a rigid cannula to remove tissue and/or fluid with the assistance of vibrational energy and aspiration. The disposable wand is designed to be image-guided, such as passing through the working channel of various neuro-endoscope trocars, allowing visualization of the procedure. To aid in tissue and/or fluid removal, the Apollo Generator provides the saline irrigation and vibrational energy to the Wand to ensure the Wand does not become clogged. Aspiration of the tissue and/or fluid is performed by the Apollo Vacuum Pump. Any tissue and/or fluid removed is collected in the Apollo Collection Canister. Activation of saline infusion and vibrational energy is controlled by the Apollo Foot Switch.

Ask a specific question about this device

The Apollo™ System is used for the controlled aspiration of tissue and/or fluids during surgery of the Ventricular System. The Apollo™ disposable wand is inserted through the working channel of a neuroendoscopic trocar.

The Apollo System is a two component surgical instrument designed to aid a physician in the removal of tissue and/or fluids during endoscopic-assisted microneurosurgery. The reusable component has three functions. These functions are vacuum generation, generation of vibrational energy, and saline irrigation. The disposable component, "the Wand" is a rigid cannula to remove tissue and/or fluid with the assistance of vibrational energy and aspiration. The disposable wand is designed to pass through the working channel of various neuro-endoscope trocars allowing visualization of the procedure. The method of action of removal is first vacuum aspiration, which draws the tissue and/or fluid into the lumen of the wand. Next, a vibrational wire is agitated inside the lumen of the wand facilitating movement of any tissue and/or fluid that may otherwise clog the lumen. Saline irrigation has the purpose of providing additional fluid to transport the tissue through the cannula. The irrigation and inner vibration wire components of the disposable wand provide an improvement over existing methods of suction aspiration through a cannula in that the use of the Apollo wand can prevent clogging. Intended users for this device are physicians who have received appropriate training in endoscopicassisted microneurosurgery.

The information provided describes the Penumbra Apollo™ System, a surgical instrument for tissue and fluid removal during endoscopic-assisted microneurosurgery. The study presented focuses on non-clinical testing to demonstrate the device's safety and effectiveness and its substantial equivalence to predicate devices, rather than a clinical study involving human patients or complex AI algorithms requiring ground truth established by experts.

Here's the breakdown of the acceptance criteria and the study that proves the device meets them:

1. Table of Acceptance Criteria and Reported Device Performance:

The document presents two main categories of testing: Biocompatibility and Bench-Top Testing (Design Verification). The acceptance criteria are implicitly defined by meeting established requirements and standards, and the reported performance confirms these criteria were met.

2. Sample Size for the Test Set and Data Provenance:

• Test Set Sample Size: The document does not explicitly state the numerical sample sizes for each specific test in the biocompatibility or bench-top testing. For biocompatibility, it mentions "sample extracts," "animals," and "test article clotting times," implying plural samples were tested for each. For bench-top, it states "All testing was performed using units which were 2x sterilized." While not a precise number, this indicates multiple devices were tested after being subjected to sterilization.
• Data Provenance: The studies were conducted internally by Penumbra Inc. or by contract ISO certified facilities (for sterilization). The data is non-clinical and derived from laboratory and bench-top testing, not human patient data. Therefore, there is no country of origin for patient data or retrospective/prospective classification in the usual sense.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications:

This information is not applicable to this submission. The document describes non-clinical engineering and biological testing, not a study evaluating human performance with the device or an AI algorithm requiring expert-established ground truth. The "ground truth" for these tests is based on established scientific and engineering standards (e.g., ISO 10993, IEC 60601-1, tensile strength specifications, corrosion standards).

4. Adjudication Method for the Test Set:

This information is not applicable. Since the 'test set' refers to physical devices and materials undergoing objective laboratory and bench-top measurements and observations against predefined standards, there is no need for expert adjudication in the manner of medical image interpretation or clinical outcomes. The results are quantitative measurements or qualitative observations against scientific criteria.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, Effect Size of how much human readers improve with AI vs without AI assistance:

This is not applicable. The submission describes the Penumbra Apollo™ System, which is a physical surgical instrument. It is not an Artificial Intelligence (AI) device, nor does the document describe any AI-assisted components or a study involving human readers with or without AI assistance.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

This is not applicable. As stated above, the Penumbra Apollo™ System is a physical surgical instrument and not an AI algorithm. Therefore, no standalone algorithm performance study was described or performed.

7. The type of ground truth used:

The ground truth used for these tests is based on established scientific and engineering standards and specifications.

• For Biocompatibility, the ground truth refers to whether the device meets the biological safety requirements outlined in ISO 10993-1 guidelines, with conclusions drawn from standard biological assays (e.g., cytotoxic, pyrogenicity, hemolytic effects).
• For Bench-Top Testing, the ground truth refers to whether the physical and mechanical properties of the device meet predefined engineering specifications and comply with relevant standards (e.g., IEC 60601-1, tensile strength limits, corrosion resistance).
• For Sterilization, the ground truth is achieving a Sterility Assurance Level (SAL) of 10-6, validated according to EN ISO 11135.
• For Shelf-Life, the ground truth is the maintenance of device properties over a specified period, verified through accelerated and real-time aging studies against finished goods release requirements.

8. The Sample Size for the Training Set:

This information is not applicable. This is not a machine learning or AI device that requires a distinct "training set." The device development followed traditional engineering design and testing methodologies.

9. How the Ground Truth for the Training Set was Established:

This information is not applicable for the same reason as point 8.
