The ProtekDuo Mini Veno-Venous Cannula Set is intended for use as a single cannula for both venous drainage and reinfusion of blood via an internal jugular vein during extracorporeal life support procedures.

Device Description

The ProtekDuo Mini Veno-Venous Cannula Set consists of two components: a 31 Fr. Dual Lumen Veno-Venous Cannula and a 15.5 Fr. Introducer is designed to accept a standard 0.038 inch guidewire. The ProtekDuo Mini Veno-Venous Cannula Set is intended as a single patient, single use, sterile device.

The ProtekDuo Mini Veno-Venous Cannula (Figure 5-1) consists of two distinct lumens with a wire-reinforced cannula body. The inner lumen is located entirely within the outer lumen forming two concentric channels.

The distal section (inner lumen/cannula) of the cannula body has six side holes near the distal tip opening. The proximal sections of each lumen are clear and not wire-reinforced to allow visualization of blood and to enable clamping to prevent blood flow during setup and removal of the cannula from the extracorporeal circulatory support equipment (see Figure 5-1). A non-vented barbed connector is affixed to both proximal ends (inner/distal and outer/proximal lumens) of the cannula and allow for connection of standard 3/8 inch blood circuit tubing for subsequent connection to extracorporeal circulatory support equipment.

The introducer (Figure 5-2) consists of a tube with a luer hub. The introducer fits inside the inner lumen of the cannula during insertion of the cannula/introducer assembly. The introducer is used to advance the cannula over a guidewire and facilitate cannula placement within the target vessel. The introducer has a luer hub at its proximal end to manage introducer insertion and removal from the cannula. The luer hub can also enable contrast injection, if necessary, to facilitate placement and final positioning of the cannula within the target vessel. The hemostasis cap minimizes blood loss when the cannula/introducer assembly is inserted into the target vessel. The introducer body is constructed from radiopaque material for visualization under fluoroscopy.

2. Sample Size Used for the Test Set and Data Provenance:

The document does not specify the exact sample sizes (number of devices, repeats per test, etc.) for the non-clinical tests conducted. The data provenance is also not explicitly stated in terms of country of origin or retrospective/prospective nature, but these are bench-top non-clinical tests.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications:

Not applicable. This is a non-clinical device performance study, not a study involving human interpretation of data where expert ground truth would be required.

4. Adjudication Method for the Test Set:

Not applicable. This is a non-clinical device performance study.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:

No, an MRMC comparative effectiveness study was not done. This is a non-clinical device performance study.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:

Not applicable. This is a physical medical device, not an AI algorithm. The performance described is for the device itself.

7. The Type of Ground Truth Used:

For the non-clinical tests, the "ground truth" or reference was based on established engineering principles, design specifications, and direct measurement of the device's physical properties and performance against predetermined criteria (often derived from the predicate device's performance or industry standards).

8. The Sample Size for the Training Set:

Not applicable. This is a physical medical device, not a machine learning model requiring a training set.

9. How the Ground Truth for the Training Set Was Established:

Not applicable. This is a physical medical device.

Dear Greg Johnson:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

intended use as the TandemHeart 31 Fr. (31 Fr. ProtekDuo) Veno-Venous Cannula Set. All materials and methods of manufacture are identical.

Summary of Non-clinical Testing

Testing of the ProtekDuo Mini Veno-Venous Cannula Set included comparative hemolysis, pressure-flow testing, tensile strength, pathway integrity, kink radius, and stiffness.

Test	Method	Conclusion
ComparativeHemolysis	Side-by-side comparison withpredicate of bench tophemolysis levels over 6 hours.	No difference in hemolysis levelsbetween test articles and predicatecontrols.
Pressure-Flow	Measure pressure losses acrosscannula at different flow rates.	Measured flow rates exceed thelonger predicate at all levels ofpressure difference across thecannula. Design specificationswere met.
Tensile Strength	Pull testing of both cannula andintroducer	Acceptance criteria were identicalto those of the predicate and weremet in all tests.
Pathway Integrity	Pressure testing	Acceptance criterion was identicalto that of the predicate and was metin all tests.
Kink Radius	Flow rate reduction caused byspecified minimum bend radiuswas measured	Acceptance criterion was identicalto that of the predicate and was metin all tests.
Stiffness	Deflection testing to measureforce required to bend cannulaa specified distance	The cannula, the introducer, and thecannula/introducer assembly metacceptance criteria established toensure the cannula is stiff enough toinsert while remaining flexibleenough to avoid vessel injury.

Conclusion

The ProtekDuo Mini Veno-Venous Cannula Set is made from the same materials, using the same manufacturing processes and sterilization techniques as the predicate device. Testing demonstrated that hemolysis, tensile strength, pathway integrity, and kink radius are identical to the predicate. Stiffness and pressure-flow properties differed as expected for the shorter length cannula and met established acceptance criteria. The ProtekDuo Mini Veno-Venous Cannula Set is determined to be substantially equivalent to the predicate TandemHeart 31 Fr. (31 Fr. ProtekDuo) Veno-Venous Cannula Set.
