No
The document describes a mechanical aspiration system for removing blood clots and does not mention any software or algorithms that would utilize AI or ML.
Yes.
The device is used for revascularization and removal of thrombus in patients with acute ischemic stroke, which directly treats a medical condition.
No
The device is indicated for revascularization and removal of thrombus, which are therapeutic actions, not diagnostic ones. Although it uses fluoroscopy for visualization, this is for guiding the therapeutic procedure rather than for diagnosing the condition itself.
No
The device description clearly outlines physical components (catheter, tubing) made of various materials, indicating it is a hardware-based medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections.
- Device Function: The Socrates Aspiration System is a medical device used directly within the body (intracranially) to physically remove blood clots causing stroke. It is a therapeutic device, not a diagnostic test performed on a sample outside the body.
- Intended Use: The intended use clearly describes a procedure for revascularization by removing a physical obstruction (thrombus) from blood vessels.
- Device Description: The description details a catheter and tubing designed for aspiration within the neurovasculature.
- Performance Studies: The performance studies focus on the physical function of the device in removing clots and its impact on the vessel, not on the accuracy of a diagnostic test.
Therefore, the Socrates Aspiration System falls under the category of a therapeutic medical device, not an In Vitro Diagnostic.

Intended Use / Indications for Use
As part of the Socrates Aspiration System, the Socrates 38 Aspiration Catheter with a compatible suction pump is indicated for use in the revascularization of patients with acute ischemic stroke secondary to intracranial large vessel occlusive disease (within the internal carotid, middle cerebral -M1 and M2 segments, basilar, and vertebral arteries) within 8 hours of symptom onset. Patients who are ineligible for intravenous tissue plasminogen activator (IV t-PA) or who fail IV t-PA therapy are candidates for treatment.
As part of the Socrates Aspiration System, the Socrates Aspiration Tubing is indicated to connect the Socrates 38 Aspiration Catheter to a compatible suction pump.

Device Description
The Scientia Vascular Socrates Aspiration System is composed of two components: the Socrates 38 Aspiration Catheter, designed to aid in accessing vasculature, and the Socrates Aspiration Tubing, designed to connect the aspiration catheter to a compatible suction pump and control flow between them. When used with a compatible vacuum pump, these components facilitate the aspiration and removal of thrombus from the neurovasculature. Both components are supplied sterile for single use only.
The Socrates 38 Aspiration Catheter is a single lumen, variable stiffness catheter designed to be advanced over a steerable guidewire. The catheter shaft design includes nitinol, polymers of varying durometer, and an internal lubricious liner. To reduce friction during manipulation, a hydrophilic coating is applied to the distal exterior section of the catheter shaft. A single radiopaque tip marker provides visualization under fluoroscopy. The proximal end of the catheter includes a clear hub with Luer lock and a stainless-steel strain relief. The catheter is supplied sterile, for single use only and is packaged with a rotating hemostasis valve (RHV).
The Socrates Aspiration Tubing is designed to connect the Socrates 38 Aspiration Catheter to a compatible vacuum pump and control flow between them. The aspiration tubing consists of tubing attached to a suction connector on one end and a male Luer lock on the other with an intermediate on/off fluid flow control device and is supplied sterile and for single use only.

Animal Study
12
The safety and effectiveness of the Socrates Aspiration System was evaluated in a comparative animal study conducted under Good Laboratory Practices (GLP) in a porcine model against a control (the Penumbra System with the ACE 68 Reperfusion Catheter). Assessments included aspiration of experimental soft and firm clots and application of maximum vacuum with the device in a wedged position against the vessel wall. Both the subject and control systems were evaluated at subacute (3 day) and chronic (30 day) time points. Clot aspiration and wedge assessment results were comparable between the test and control systems. Angiographic and histological evaluations concluded the systems were comparable at all time points.
CLINICAL PERFORMANCE DATA
The non-clinical performance data presented were determined to be sufficient to support the substantial equivalence of the Socrates Aspiration System. Therefore, no clinical study was conducted.
CONCLUSION
The subject device, Socrates Aspiration System, has the same intended use and similar indications for use as the predicate device. The differences in technological characteristics do not raise new questions of safety or effectiveness and have been evaluated through testing and the resulting data demonstrate that the subject device, Socrates Aspiration System, is substantially equivalent to the predicate.
