The description focuses on the physical characteristics and function of a mechanical shunt, with no mention of AI or ML.
No
The device provides a temporary blood-free operative field for suturing during coronary artery or peripheral vascular procedures, which is an operative aid, not a long-term therapeutic effect.
No
The device is described as an intraluminal shunt used to maintain blood flow distal to an anastomotic site during surgery, providing a temporary blood-free operative field for suturing. It facilitates a medical procedure rather than diagnosing a condition.
No
The device description clearly states it is a "sterile, single-use Flo-Thru Intraluminal Shunt (FTIS)" which is a physical, radiopaque silicone tube with bulbs and a tab. This is a hardware device, not software.
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, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Flo-Thru Function: The description clearly states that the Flo-Thru is a device used during surgical procedures (coronary artery or peripheral vascular procedures) to shunt blood and provide a temporary blood-free operative field. It is a physical device inserted into a blood vessel.
- No Sample Analysis: There is no mention of the device analyzing any biological samples or providing diagnostic information based on such analysis. Its function is purely mechanical and procedural.
Therefore, the Flo-Thru Intraluminal Shunt is a surgical device, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The Flo-Thru is indicated for use in coronary artery or peripheral vascular procedures. The device shunts blood at the anastomotic site which provides a temporary blood-free operative field for suturing while allowing blood to flow distal to the anastomosis. The device is removed just prior to the final suturing of the vessel.

Device Description
The sterile, single-use Flo-Thru Intraluminal Shunt (FTIS) is a one-piece radiopaque silicone tube with atraumatic bulbs shaped at each end. Openings at the bulbs allow blood to flow through the shunt and distal to the anastomotic site. A radiopaque tab, which identifies the outer diameter of the bulbs, is attached to the shunt by a tether to facilitate positioning and removal of the shunt.

Summary of Performance Studies
Functional testing conducted on the Flo-Thru intraluminal shunt and predicate samples show the Flo-Thru performs in a manner substantially equivalent with regard to strength, and flow rate. Handling characteristics, flexibility, and radiopacity of the Flo-Thru device meet design requirements. Also, the Flo-Thru has no memory of kinking or manipulation.
