The device description and performance studies focus on the physical characteristics and mechanical performance of a guide sheath, with no mention of AI or ML.
No.
The device is described as a guide sheath for introducing interventional devices, not a device that directly provides therapy itself.
No
The device is a guide sheath designed to introduce other interventional devices into the neurovasculature, not to perform diagnosis itself. While the dilator component is compatible with "diagnostic guidewires," the device's function is purely instrumental for intervention, not diagnostic data acquisition.
No
The device description clearly details a physical catheter, dilator, and hemostasis valve, which are hardware components. The performance studies also focus on physical properties and testing of these hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "introduction of interventional devices into the neuro vasculature." This describes a device used within the body for a medical procedure, not a device used to test samples outside the body to diagnose a condition.
- Device Description: The description details a catheter designed for insertion into blood vessels, facilitating the passage of other devices. This aligns with an interventional medical device, not an IVD.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any process related to diagnosing a disease or condition through in vitro testing.
- Performance Studies: The performance studies focus on the physical and mechanical properties of the catheter (dimensions, strength, flexibility, trackability, etc.) and its performance in an in vitro model and in vivo testing in a porcine model. These are typical tests for interventional devices, not IVDs.
In summary, the CEREBASE DA Guide Sheath is an interventional medical device used for accessing the neuro vasculature, not a device used for in vitro diagnostic testing.

Device Description
The CEREBASE DA Guide Sheath is a single lumen, stainless steel braided catheter of variable stiffness with a large non-tapered lumen that facilitates the intravascular passage of interventional devices. The guide sheath is a straight shaped catheter that comes in four lengths; 70 cm, 80 cm, 90 cm, and 95 cm. The lubricious PTFE-lined inner lumen is designed to facilitate delivery of the interventional devices. It has a radiopaque marker band on the distal end and a luer hub at the proximal end. The guide sheath has an outer hydrophilic coating at the distal end that reduces friction during use. A hemostasis valve and a dilator are provided with the CEREBASE DA Guide Sheath within its sterile packaging. The dilator is a single lumen radiopaque catheter with a tapered distal end and a luer hub at the proximal end. The dilator is compatible with the CEREBASE DA Guide Sheath and up to 0.038 inch diagnostic guidewires. The hemostasis valve with side port is an off the shelf component used for flushing and insertion of catheters.

| IV. Device
Description,
Continued | The CEREBASE DA Guide Sheath's lumen must be flushed and outer body wet with
heparinized saline solution prior to use. If using as a primary access sheath with the
dilator, the dilator must be soaked and flushed with heparinized saline solution as well
prior to use. After being flushed with heparinized saline solution the dilator can then
be inserted and advanced until the tapered distal tip is beyond the distal end of the
CEREBASE DA Guide Sheath. Then the hemostasis valve is closed around the dilator
and primary access can be gained to the vasculature using a standard technique of
choice. |

- VIII. Conclusion Based upon the intended use, design, materials, function, side-by-side in-vitro testing and animal testing, and passing biocompatibility test results, it is concluded that the subject device, CEREBASE DA Guide Sheath is substantially equivalent to the predicate device, Neuron MAX System (K111380, cleared 19 July 2011). The fundamental scientific technology is the same as the predicate device. The differences in verbiage in the Indications for Use statement only limits the locations that the subject device can be used and do not raise any questions regarding the safety and effectiveness of the device. Risk assessment of the CEREBASE DA and verification/validation testing confirmed the device is as safe and effective as the predicate device.
