Intended Use

The TenderFlow™ Pediatric Arterial Cannula is a surgically invasive device intended for short term use and indicated for cannulation and perfusion of the ascending aorta during cardiopulmonary bypass surgery. These devices are indicated for up to 6 hours of use.

Device Description

The design of the TenderFlow™ Pediatric Arterial Cannula consists of a dip molded, wire reinforced cannula (single-stage) with thin walls and good flow performance. A non-reinforced clamping site is provided adjacent to the connector. The overall length of the cannula from end to end is approximately 9 inches. The distal portion of the spring reinforced body steps up in size both in internal diameter and outside diameter to enhance flow performance. This stepup diameter is approximately four to five French sizes larger than the tip section. The step occurs distal to the insertion portion of the cannula at approximately 1 to 2 inches from the tip. The length of the step increases with the French size. The tip is integral to the body, is not spring reinforced and is stiffened sufficiently to resist kinking and/or collapse. The pediatric arterial cannula has a ¼" barbed connector in either a vented (with luer cap) or non-vented design. The pediatric arterial cannula also includes an optional introducer with a vent cap. This introducer can be used to stiffen the cannula during insertion and reduce blood loss.

AI/ML (Artificial Intelligence / Machine Learning)

No
The description focuses on the physical design and performance characteristics of a surgical cannula, with no mention of software, algorithms, or data processing that would indicate the use of AI/ML.

Therapeutic

No.
The device is an arterial cannula used for cannulation and perfusion during bypass surgery, which is a supportive function during a medical procedure, not a treatment for a disease or condition itself.

Diagnostic

This device is a surgical tool used for cannulation and perfusion during cardiopulmonary bypass surgery, not for diagnosing conditions.

SaMD (Software as a Medical Device)

The device description clearly details a physical, surgically invasive cannula made of materials like wire and plastic, intended for insertion into the body. This is a hardware device, not software.

IVD (In Vitro Diagnostic)

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

Intended Use: The intended use clearly states it's a "surgically invasive device intended for short term use and indicated for cannulation and perfusion of the ascending aorta during cardiopulmonary bypass surgery." This describes a device used within the body during a surgical procedure, not a device used to test samples outside the body.
Device Description: The description details a physical cannula designed for insertion into a blood vessel. This is consistent with a surgical device, not an IVD.
Anatomical Site: The device is used in the "ascending aorta," which is an internal anatomical site. IVDs typically analyze samples taken from the body (like blood, urine, tissue) in a laboratory setting.
Intended User / Care Setting: The device is used in "open heart surgery," which is a surgical procedure, not a diagnostic testing environment.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a surgical tool used to facilitate a medical procedure.

Device Description

The TenderFlow™ Pediatric Arterial Cannula is used in open heart surgery. During open heart surgery blood is drained into a venous cannula just upstream of the heart, at the superior / inferior vena cava and right atrium. The cannula is connected to tubing that routes the blood to a heart / lung machine where the blood is pumped and oxygenated. The blood then continues through this perfusion circuit back to the outlet side of the heart (the patient's aorta), where the blood re-enters the patient's circulatory system via the ascending aorta through an arterial cannulae.

The tip is integral to the body, is not spring reinforced and is stiffened sufficiently to resist kinking and/or collapse. The pediatric arterial cannula has a ¼" barbed connector in either a vented (with luer cap) or non-vented design. The pediatric arterial cannula also includes an optional introducer with a vent cap. This introducer can be used to stiffen the cannula during insertion and reduce blood loss.

The generic materials used in the TenderFlow™ Pediatric Arterial Cannula are as listed:

· Polyvinvl chloride for the tube
· Stainless steel wire which provides spring reinforcement throughout the body of the cannula
· Rigid PVC and UV cure adhesive for the connector
· ABS for the luer cap
· Silicone vent cap and polypropylene rod for the optional introducer
· Each cannula is printed with a medical grade white ink, pigment color Marabu TPL 970 CDT PN

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The performance of the TenderFlow™ Pediatric Arterial Cannula is substantially equivalent to the performance of the predicate (unmodified) device with regards to pressure drop testing and hemolysis testing. The hemolysis testing compared the unmodified 10 Fr. to the modified 6 Fr. device since these were the two smallest devices in both product families. The 6 Fr. performed equal to or better than the 10 Fr. unmodified device. All test results are available upon request.

Comparison studies of the performance of the (modified) Pediatric Arterial Cannula and the unmodified predicate L Series Pediatric Arterial Cannula were conducted for pressure drop versus flow rate with water testing and the dynamic hemolysis test because these speak to performance. All other tests listed below were conducted on the modified device only because these speak to device integrity.
