#### DEVICE DESCRIPTION

The Aristotle 18 Guidewire is a modification of Scientia Vascular's Aristotle 14 Guidewire. It is a 0.018" diameter steerable guidewire with a shapeable tip to aid in accessing vasculature. The guidewire is supplied sterile and is for single use only. It is provided in a range of stiffness profiles: soft, standard, and support. The product is provided in one overall length of 200cm.

The distal portion of the guidewire tip includes a radiopaque platinum wire marker coil to facilitate fluoroscopic visualization. The guidewire has 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 guidewire is provided with an introducer (to aid with the insertion of the guidewire into a catheter hub and/or a hemostasis valve) and a torque device (to attach to the proximal portion to facilitate gripping and manipulation of the guidewire during use). The introducer and torque accessory devices are included to facilitate use of the guidewire and are not intended to contact the patient's body.

The Aristotle 18 Guidewire is substantially equivalent with respect to technological characteristics, indications for use, design and materials to the previously cleared Aristotle 14 Guidewire.

#### INTENDED USE/INDICATIONS FOR USE

The Aristotle 18 Guidewire is intended for general vascular use within the neuro and peripheral vasculatures to introduce and position catheters and other interventional devices. The guidewire is not intended for use in the coronary vasculature.

### TECHNOLOGICAL CHARACTERISTICS

The Aristotle 18 Guidewire has the following similarities to the previously cleared Aristotle 14 Guidewire:

- Both devices have the same indicated use,
- Both devices use the same operating principle, ●
- Both devices incorporate the same basic guidewire design, ●
- Both devices incorporate the same materials, and ●
- Both devices are packaged and sterilized using the same materials and processes. .

{6}------------------------------------------------

The two differences between Aristotle 18 Guidewire and Aristotle 14 Guidewire is in the outer dimensions and the addition of a centering coil. The outer dimension of the Aristotle 18 Guidewire is 0.018" whereas the outer dimension of the Aristotle 14 Guidewires is 0.014". A centering coil made of stainless steel is added to the Aristotle 18 Guidewire whereas the Aristotle 14 Guidewire does not have a centering coil. However, the core wire and the centering coil are made from the same stainless steel material. Thus, no new materials were added to the Aristotle 18 Guidewire that were not present in the Aristotle 14.

### NON-CLINICAL PERFORMANCE TESTS

### Biocompatibility

The materials used in the manufacture of the subject Aristotle 18 Guidewire are identical to those used in the manufacture of the Aristotle 14 Guidewire also manufactured by Scientia Vascular LLC, cleared January 22, 2018 after review of K173235; in formulation, processing, sterilization, and no other chemicals have been added (e.g., plasticizers, fillers, color additives, cleaning agents, mold release agents).

Due to the increased diameter of the subject device compared to the predicate device and the risk assessment of these design differences, new biocompatibility testing was conducted including an in vitro blood flow loop thrombogenicity study, MEM elution, toxicological risk assessment, ASTM hemolysis (direct contact), ASTM hemolysis (extract), partial thromboplastin time (PTT), and complement activation to establish that the increased surface area of the Aristotle 18 Guidewire would not result in an increased thrombogenic potential compared to the Aristotle 14 Guidewire predicate device. and further demonstrate the biocompatibility profile of the subject device is equivalent to the predicate device.

#### Sterilization

100% EO is used to sterilize the device to achieve a SAL of at least 10-9. The device was adopted into an EO sterilization processing group in accordance with AAMI TIR 28:2016. Completion of the review performed to the requirements of AAMI TIR 28:2016 indicate the Aristotle 18 and the Aristotle 14 are similar with regards to all device and packaging characteristics that could affect the ability to sterilize the devices.

#### Functional Testing

Performance testing on the subject device was performed after conducting a risk assessment in accordance with EN ISO 14971:2012 Medical Devices – Risk Management. Functional testing was performed in accordance with ISO 11070:2014 Sterile single-use intravascular introducers, dilators and guidewires and the FDA Guidance Document Coronary and Cerebrovascular Guidewire Guidance (January 1995). The following table summarizes the functional tests performed and test results obtained to demonstrate substantial equivalence to the predicate device:
