No
The device description clearly outlines a physical catheter with balloons, intended for a surgical procedure. There is no mention of software as the primary or sole component of the device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The OutFlo Aortic Valve Dilatation Balloon Catheter is a physical device used within the body to perform a therapeutic procedure (balloon aortic valvuloplasty) on the aortic valve. It does not analyze specimens outside the body.
- Intended Use: The intended use is for a surgical procedure to treat aortic valve stenosis, not for diagnostic testing of samples.
The information provided clearly describes a medical device used for an interventional procedure, not an in vitro diagnostic test.

Device Description
The OutFlo Aortic Valve Dilatation Balloon Catheter (marketing name: OutFlo) is a sterile, single use, Over-the-Wire (OTW) dual-lumen catheter with a hub at the proximal end and a balloon cluster at the distal end.
The proposed device consists of a series of parallel balloons on a catheter which, when deployed, provides an outward radial force while also creating an inter balloon space or passage for blood flow. Thus, buildup of pressure in the ventricle is avoided.
The dilation catheter is intended to be used in conjunction with a 14F or larger guiding catheter and a 0.035" or smaller guidewire, and Y-connectors, none of which are supplied by the manufacturer.
The OutFlo Aortic Valve Dilatation Balloon Catheter is provided in five models. The only difference between the models are the balloon diameter. Refer to Table 1 for the specifications for each of the 5 models.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A prospective, multi-center, observational study was conducted on the OutFlo Aortic Valve Dilatation Balloon Catheter for use in the treatment of aortic valve stenosis. The study was intended to evaluate the ability of the OutFlo to be deployed within the aortic valve while allowing blood flow through the inter-balloon space, thus eliminating the need for pacing during the procedure. The study enrolled 40 subjects across five centers. Performance of the device was evaluated by the investigators and subjects were evaluated based on freedom from major adverse events (MAE) and death. Results demonstrated a 98% procedural success rate, no reported deaths, and no reported MAEs related to the device or valvuloplasty procedure. The clinical testing supports substantial equivalence of the device to the predicate and complies with special controls as defined in 21 CFR 870.1255 (b)(4).
