No
Explanation: The device is a venous return cannula used for draining blood during cardiopulmonary bypass surgery. Its purpose is therapeutic, not diagnostic.
No
The device description explicitly details physical components made of polyvinyl chloride and stainless steel wire, and the performance studies involve physical tests like pressure drop, hemolysis, and mechanical tests (clamp, kink, collapse, tensile). This indicates a hardware device, not software only.
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 outside of the body.
- Device Description and Intended Use: The TenderFlow™ Pediatric Venous Return Cannula is a surgically invasive device used within the body during cardiopulmonary bypass surgery. It is inserted into the superior and inferior vena cava and the right atrium for venous drainage.
- Lack of Diagnostic Function: The device's purpose is to facilitate blood flow during surgery, not to diagnose any condition or analyze biological samples.
Therefore, the TenderFlow™ Pediatric Venous Return Cannula is a surgical device, not an in vitro diagnostic device.

Device Description
The design of the TenderFlow™ Pediatric Venous Return Cannula consists of a dip molded, wire reinforced, straight venous return cannula (single-stage) with thin walls, and good flow performance. A non-reinforced clamping site is provided adjacent to the flared connection site. The overall length of the cannula from end to end is 12 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 step-up diameter is approximately three French sizes larger than the tip section. The step occurs distal to the insertion portion of the cannula at approximately 3 to 5.5 inches from the tip. The length of the step increases with the French size.
The tip is integral to the body, not spring reinforced and is stiffened sufficiently to resist kinking and/or collapse.
The generic materials used in the TenderFlow™ Pediatric Venous Return Cannula are polyvinyl chloride and stainless steel wire which provides spring reinforcement throughout the body of the cannula. Each cannula is printed with a medical grade white ink, pigment color Marabu TPL. 970 CDT PN.

Device Names:
Proprietary Name: TenderFlow™ Pediatric Venous Return Cannula Common Name: Venous Return Cannula Venous Return Cannulae are classified as Class II devices Classification:
Predicate Device:
The TenderFlow™ Pediatric Venous Return Cannula is substantially equivalent in intended use, materials, design, technology, principles of operation, and performance to the (unmodified) Terumo L. Series Pediatric Venous Return Cannula. This device was in commerce prior to May 1976 and is considered a pre-amendment device. The pre-amendment status of this device was claimed by C.R. Bard at the time. This device is legally marketed and has not been the subject of Premarket Notification 510(k) clearance.
Intended Use:
The TenderFlow™ Pediatric Venous Return Cannula is a surgically invasive device indicated for dual cannulation of the superior and inferior vena cava and single cannulation of the right atrium for venous drainage during cardiopulmonary bypass surgery. These devices are indicated for up to 6 hourse pofuse
Principles of Operation and Technology:
The TenderFlow™ Pediatric Venous Return 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 an arterial cannulae.

Substantial Equivalence Comparison:
The TenderFlow™ Pediatric Venous Return Cannula is substantially equivalent to the predicate Terumo L Series Pediatric Venous Return Cannula device as follows:
3
Intended Use: The TenderFlow™ Pediatric Venous Return Cannula and the predicate (unmodified) Terumo L Series Pediatric Venous Return Cannula share the same intended uses. Both are indicated for venous & drainage during bypass surgery for up to 6 hours of use.
Principles of Operation and Technology: Both the modified and unmodified pediatric cannulae are used in open heart surgery to drain the blood out of the superior and/or inferior vena cava as well as the right atrium portion of the heart. This blood is removed from the heart through the cannula into the perfusion circuit tubing which connects to the heart lung bypass machine.
Design and Materials: The design of the TenderFlow™ Pediatric Venous Return Cannula consists of a dip molded, wire reinforced, straight venous return cannula (single-stage) with thin walls, and good flow performance. A non-reinforced clamping site is provided adjacent to the flared connection site and seath to of the cannula from renditorend is 12 and help is integral to the body, and is not spring reinforced. The tip is stiffened sufficiently to resist kinking and/or collapse.
The shape and hole pattern of the modified pediatric cannula is similar to that of the predicate (unmodified) L Series Pediatric Venous Return Cannula. Both cannulae (modified and unmodified) are wire reinforced, have 8 blood flow exit ports on the sides, a rounded tip that is not spring reinforced and a non-wire reinforced flared connector site.
There are two major differences between the modified and unmodified devices is that the modified devices also have a blood flow exit port in the tip itself, aside from the blood flow exit ports on the sides. The other difference is that the distal portion of the spring reinforced body steps up in size both in internal diameter and outside diameter to enhance flow performance. This step-up diameter is approximately three French sizes larger than the tip section. The step occurs distal to the insertion portion of the cannula at approximately 3 to 5.5 inches from the tip. The length of the step increases with the French size.
The design and the materials of the (modified) and the (unmodified) L Series Pediatric Venous Return Cannula are essentially the same. Differences include the graduated steps in the tubing of the modified device vs. a straight cannula body in the unmodified predicate device. An optional angled version is offered for the modified device in addition to straight cannulae. An optional 3/8 inch flare connection site is offered on the 18, 20, and 22 Fr. sizes of the modified device. The 24 Fr. size of the modified device only has a 3/8 inch flare connection site.
The materials used in the two devices are identical. Both use polyvinyl chloride and stainless steel for the spring reinforcement.

Performance: Comparison studies of the performance of the (modified) Pediatric Venous Return Cannula and the unmodified predicate L Series Pediatric Venous Return Cannula were conducted for pressure drop testing and hemolysis testing. The results of these tests proved the modified device to be substantially equivalent or better than the predicate (unmodified) pediatric venous return cannula. Additional testing was performed on the modified Pediatric Venous Return Cannula to demonstrate current conformance to current market place performance expectations. These tests include:
- . Connector attachment
- Clamp test .
- Kink test .
- Collapse test .
- Tensile test .
- Simulated use test .
- Ship test .
- Shelf Life test .
These test results showed either no or favorable clinically significant performance differences.
Substantial Equivalence Summary:
In summary, the (modified) TenderFlow™ Pediatric Venous Return Cannula and the predicate (unmodified) L Series Pediatric Venous Return Cannula are substantially equivalent in intended use, principles of operation and technology, design, materials, and performance. Any noted differences between the devices do not raise new issues of safety and effectiveness.
