The device description and performance studies focus on the physical characteristics and flow dynamics of a cannula set, with no mention of AI or ML.
Yes.
The device is intended to cannulate vessels, perfuse vessels or organs, and/or connect with accessory extracorporeal circulatory support equipment, which are therapeutic interventions.
No
The document states the device is intended to "cannulate vessels, perfuse vessels or organs and/or connect with accessory extracorporeal circulatory support equipment," which are therapeutic or support functions, not diagnostic ones.
No
The device description clearly outlines physical components (cannula, obturator, dilator) made of materials like radiopaque material and includes features like side holes, barbed fittings, and suture wings. This indicates a hardware-based medical device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used to cannulate vessels, perfuse vessels or organs, and connect with extracorporeal circulatory support equipment. This is a direct intervention on the patient's body for therapeutic or support purposes.
- Device Description: The description details a physical device (cannula, obturator, dilator) designed for insertion into the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used in vitro (outside the body) to analyze samples. This device is used in vivo (inside the body) for direct medical intervention.

Intended Use / Indications for Use
The TandemHeart Venous Cannula Set is intended to cannulate vessels, perfuse vessels or organs and/or connect with accessory extracorporeal circulatory support equipment. The cannula obturator and dilator are intended to facilitate proper insertion and placement of the cannula within the vessel for extracorporeal circulatory support.

Device Description
The TandemHeart Venous Cannula Set consists of three components, as shown in Figure 1: a 21 Fr. Venous Cannula. 14 Fr. Obturator, and an optional 14/21 Fr. Two-stage Dilator, that accepts a 0.035 in. guidewire. The device is intended to cannulate vessels or organs, and/or connect with accessory extracorporeal circulatory support equipment. The product is intended to be single patient, single use, sterile device.
The cannulae are available in two configurations:
-
- 21 Fr. x 62 cm. with options for tip curvature of 0° and 50°
-
- 21 Fr. x 72 cm. with tip curvature of 50°
The cannula has multiple side holes in addition to the tip opening for unimpeded flow of blood at the distal end and a barbed fitting at the proximal end to enable the connection of 3/8" tubing. Radiopaque markers are embedded at the distal tip of the cannula, and the cannula body is wirereinforced for visualization under fluoroscopy. Insertion depth markings are incorporated in the cannula body from 10 to 62 or 72 cm, depending on the length option, measured from the distal tip.
The cannula includes a suture wing to provide a means for securing the cannula to the patient. Printing on the proximal region of the cannula indicates the area where a clamp should be applied if needed during the set-up or the removal process.
The 14 Fr. Obturator is provided to facilitate placement of the venous cannula, within the target vessel, and is designed with a tapered distal tip. The Obturator proximal end contains a luer hub to aid in the removal of the obturator. The Obturator body is constructed of a radiopaque material for visualization under fluoroscopy:
The Obturator includes a hemostasis cap that provides the interface between the cannula proximal connector and obturator body. The hemostasis cap aids in minimizing blood loss during the insertion of the cannula/obturator assembly into the target vessel.
The 14/21 Fr. Dilator is provided to aid introduction of the obturator/cannula assembly at the insertion site.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical performance testing was conducted to demonstrate substantial equivalence of flow characteristics between the TandemHeart Venous Cannula Set and the predicate. Medtronic Bio-Medicus Femoral Venous Cannula. The performance testing included in-vitro system capacity testing and flow vs. pressure drop (HQ). This testing verified that despite the longer length of the TandemHeart Venous Cannula and distal tip taper relative to the Bio-Medicus Femoral Venous Cannula, it was able to sustain flows comparable to the predicate.
Flexibility, strength, biocompatibility, in-vitro hemolysis, leak testing, sterilization, and shelf life of the TandemHeart Venous Cannula are addressed by comparison with reference devices, specifically the CardiacAssist Transseptal Cannula Set-EF and EF-72 that were cleared under K052570 and K082425, respectively. Based on the performance test results and data from these two other devices, the TandemHeart Venous Cannula Set was found to meet established design input requirements and thus to be substantially equivalent to the predicate Medtronic Bio-Medicus Femoral Venous Cannula and Introducer.

Intended Use
The TandemHeart Venous Cannula Set is intended to cannulate vessels, perfuse vessels or organs and/or connect with accessory extracorporeal circulatory support equipment. The cannula obturator and dilator are intended to facilitate proper insertion and placement of the cannula within the vessel for extracorporeal circulatory support.
Comparison of Technological Characteristics
The TandeinHeart Venous Cannula Set and the predicate Medtronic Bio-Medicus Femoral Venous Cannula and Introducer both consist of a wire-reinforced, polyurethane venous cannula and a polyurethane obturator. There are also a number of technological differences: 1) the TandemHeart Venous Cannula Set contains an additional component located on the exterior proximal portion of the cannula: a suture wing to provide a means of securing the cannula to the patient; 2) the 72 cm TandemHeart Venous Cannula Set contains two Suture Rings for securing the cannula to the patient; 3) the TandemHeart Venous Cannula includes a distal tip taper, while the predicate has a straight tip; 4) the TandemHeart Venous Cannula is longer than the predicate to allow improved flexibility in positioning within the venous system; 5) the TandemHeart Venous Cannula features three radiopaque disks at the distal tip of the cannula; and 6) the TandemHeart Venous Cannula Set includes a 14/21 Fr. dilator to be used at the physician's discretion for additional aid in inserting the obturator/cannula assembly. All of the technological differences are part of the set's design to aid in the insertion. positioning and securing of the cannula.
