The guidewire is not intended for use in the coronary vasculature.
Device Description
The Scientia Vascular's Aristotle 18 Guidewire and Aristotle 24 Guidewire are steerable guidewires with a shapeable tip to aid in accessing the neuro and peripheral vasculatures. The guidewires are supplied sterile, for single use only, in the following diameters, stiffness profiles, and lengths: Aristotle 18 Guidewire Diameter: 0.018" Stiffness Profiles: Soft, Standard, Support Length: 200 cm, 300 cm Aristotle 24 Guidewire Diameter: 0.024" Stiffness Profiles: Soft, Standard, Support Length: 200 cm, 300 cm The distal portion of each guidewire's tip includes a radiopaque platinum wire marker coil to facilitate fluoroscopic visualization. All guidewires have a hydrophilic polymer coating on the distal portion and a polytetrafluoroethylene (PTFE) coating on the proximal portion to reduce friction during manipulation in vessels. The guidewires are provided with an accessory kit consisting of an introducer (to aid with the insertion of the guidewire into a catheter hub and/or a hemostasis valve), a torque device (to attach to the proximal portion of the guidewire to facilitate gripping and manipulation of the guidewire during use), and a shaping mandrel (to aid in shaping the flexible tip of the guidewire). These accessory devices are included to facilitate use of the guidewires and are not intended to contact the patient's body.
More Information

No
The device description and performance studies focus on the physical characteristics, materials, and mechanical performance of a guidewire, with no mention of AI or ML capabilities.

No.
The device is a guidewire intended to introduce and position other interventional devices, not to provide therapy itself.

No
Explanation: The Intended Use/Indications for Use states that the guidewires are "to introduce and position catheters and other interventional devices," clearly indicating an interventional or therapeutic purpose, not a diagnostic one.

No

The device description clearly outlines physical components like guidewires, radiopaque markers, coatings, and accessory kits, indicating it is a hardware medical device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the guidewire is for "general vascular use within the neuro and peripheral vasculatures to introduce and position catheters and other interventional devices." This describes a device used within the body for procedural purposes, not for testing samples outside the body to diagnose conditions.
  • Device Description: The description details a physical guidewire with coatings and accessories for manipulation within blood vessels. 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 diagnostic testing procedures.

IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This guidewire does not fit that description.

10

The Aristotle 18 Guidewire and Aristotle 24 Guidewire have been modified to include additional models of longer length with added 100 cm of proximally PTFE coated guidewire for a total guidewire length of 300 cm. The Aristotle 24 Guidewires have been previously cleared with a total guidewire length of 200 cm in K183608 and K192783, respectively. This additional length does not impact any features or dimensions at the distal end of the guidewire and does not raise new questions of safety and effectiveness.

NON-CLINICAL PERFORMANCE TESTS

Biocompatibility

Biocompatibility testing was conducted for the reference devices (K222347, K173235). These results support the biocompatibility of the subject devices because they use the same materials, processes, components, and dimensions within the range of the previously cleared predicate and reference devices. The evaluation supports that the subject device with its accessories meets biological safety requirements per ISO 10993-1:2018 for externally communicating medical devices with circulating blood contact for a limited duration (less than 24 hours).

Sterilization

The subject devices have been adopted into a validated sterilization cycle that uses 100% EO to achieve a sterilization assurance level (SAL) of 10-6.

Bench Performance Testing

The bench performance testing conducted for the reference devices (K222347, K173235) and the predicate 200 cm long models of the subject guidewires cleared under K183608 and K192783, support the performance of the subject devices (300 cm) because they use the same materials, processes, components, and dimensions within the range of the previously cleared predicate and reference devices.

Following the risk assessments conducted in accordance with ISO 14971, no additional testing was deemed necessary to support the substantial equivalence of the subject device models.

Animal Testing

No animal testing was deemed necessary to support the substantial equivalence of the subject devices.

Clinical Testing

No clinical testing was deemed necessary to support the substantial equivalence of the subject devices.

CONCLUSION

The Aristotle 18 Guidewire and Aristotle 24 Guidewire have the same intended use and indications for use statement as their respective predicate devices. The identified technological difference does not raise new questions of safety or effectiveness regarding the use of the subject devices. Risk evaluation was completed for the subject devices. The risk evaluation and testing of the predicate and reference devices demonstrate that the subject devices are substantially equivalent to their respective predicate devices.
