No
The description focuses on mechanical and control functions (delivering inflation media, controlling pressure and time, monitoring temperature) and does not mention any AI/ML capabilities for analysis, prediction, or decision-making.
Yes
The device is used for "dilatation of stenoses" and "treatment of obstructive lesions," which are therapeutic interventions.
No
The device is described as a "Peripheral Dilatation System" intended for the "dilatation of stenoses" and "treatment of obstructive lesions." This indicates a therapeutic, rather than diagnostic, function.
No
The device description explicitly lists multiple hardware components: a disposable catheter, a reusable Cryoplasty inflation unit, a disposable nitrous oxide cartridge, and a disposable catheter extension. While there is mention of "Software Verification Validation Testing," this refers to the software component of a hardware system, not a standalone software-only device.
Based on the provided information, the PolarCath Peripheral Dilatation System 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, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- PolarCath Function: The PolarCath System is a medical device used in vivo (within the living body) to physically dilate stenoses (narrowings) in blood vessels and grafts. It involves inserting a catheter and inflating a balloon within the patient's body.
- Lack of Sample Analysis: The description does not mention any analysis of biological samples. The device's function is mechanical and thermal (cryoplasty).
Therefore, the PolarCath Peripheral Dilatation System falls under the category of a therapeutic medical device used for intervention within the body, not an in vitro diagnostic device.

Intended Use / Indications for Use
The PolarCath Peripheral Dilatation System's intended use is for the dilatation of stenoses in the peripheral vasculature (iliac, femoral, popliteal, infrapopliteal, renal and subclavian arteries) and for the treatment of obstructive lesions of polytetrafluoroethylene (PTFE) access grafts or native arteriovenous dialysis fistulae. The PolarCath Peripheral Dilatation System is also indicated for post-deployed stent expansion of self-expanding peripheral vascular stents.

Device Description
The PolarCath™ Peripheral Dilatation System (PolarCath System) consists of a disposable catheter, a reusable Cryoplasty inflation unit, a disposable nitrous oxide cartridge, and a disposable catheter extension.
The PolarCath System is designed for dilatation of stenotic lesions in peripheral arteries. The procedure consists of inserting a catheter over a quidewire to the target lesion, attaching the catheter to the catheter extension, attaching the catheter extension to the Inflation Unit, inserting a nitrous oxide cartridge into the Inflation Unit, and inflating the balloon catheter for a set time at a set pressure, using the controls on the Inflation Unit.
The Cryoplasty inflation unit functions to: a) deliver the inflation media (liquid nitrous oxide) to the balloon; b) control the pressure inside the inner balloon; c) provide a vacuum between the inner and outer balloons; and d) control the length of time for delivery of the inflation media which is manually extracted at the end of the inflation time. The inflation unit monitors the temperature inside the balloon. Excess pressure is prevented by the presence of a relief valve in the inflation unit.

Predicate Device(s)
- PolarCath Peripheral Dilatation System (K092455) .
This predicate has not been subject to a design-related recall.
Indications for use
The PolarCath Peripheral Dilatation System's intended use is for the dilatation of stenoses in the peripheral vasculature (iliac, femoral, popliteal, infrapopliteal, renal and subclavian arteries) and for the treatment of obstructive lesions of polytetrafluoroethylene (PTFE) access grafts or native arteriovenous dialysis fistulae. The PolarCath Peripheral Dilatation System is also indicated for post-deployed stent expansion of self-expanding peripheral vascular stents.
The Indications for Use statement for the PolarCath Peripheral Dilatation System is identical to the predicate device.
Product Description
The PolarCath™ Peripheral Dilatation System (PolarCath System) consists of a disposable catheter, a reusable Cryoplasty inflation unit, a disposable nitrous oxide cartridge, and a disposable catheter extension.
The PolarCath System is designed for dilatation of stenotic lesions in peripheral arteries. The procedure consists of inserting a catheter over a quidewire to the target lesion, attaching the catheter to the catheter extension, attaching the catheter extension to the Inflation Unit, inserting a nitrous oxide cartridge into the Inflation Unit, and inflating the balloon catheter for a set time at a set pressure, using the controls on the Inflation Unit.
The Cryoplasty inflation unit functions to: a) deliver the inflation media (liquid nitrous oxide) to the balloon; b) control the pressure inside the inner balloon; c) provide a vacuum between the inner and outer balloons; and d) control the length of time for delivery of the inflation media which is manually extracted at the end of the inflation time. The inflation unit monitors the temperature inside the balloon. Excess pressure is prevented by the presence of a relief valve in the inflation unit.
TECHNOLOGICAL CHARACTERISTICS
The technological characteristics of the PolarCath System are similar to the predicate device. Available performance data support the determination of substantial equivalence.
SUBSTANTIAL EQUIVALENCE
The proposed indications for use for the proposed device is substantially equivalent to the indications for use for the predicate device. Any differences in the technological characteristics between the devices do not raise any new issues of safety or effectiveness. Thus, the PolarCath System is substantially equivalent to the predicate device.
