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.
No.
Explanation: This device is a cannula set used for blood drainage and reinfusion during extracorporeal life support procedures, which is a supportive rather than a therapeutic function. Therapeutic devices actively treat a condition, whereas this device facilitates a life-sustaining support process.
No
The device is a cannula set used for extracorporeal life support procedures, facilitating blood drainage and reinfusion, rather than diagnosing a condition.
No
The device description clearly outlines physical components (cannula, introducer) made of materials like wire-reinforced bodies and radiopaque material, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "venous drainage and reinfusion of blood via an internal jugular vein during extracorporeal life support procedures." This describes a procedure performed directly on the patient's circulatory system, not a test performed on a sample taken from the body.
- Device Description: The description details a cannula and introducer designed for insertion into a blood vessel to manage blood flow. This is a surgical/interventional device, not a device used for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of the device being used to analyze blood, tissue, or any other biological sample to provide diagnostic information. The device's function is mechanical – to facilitate blood flow during a medical procedure.
IVD devices are used to examine specimens derived from the human body (like blood, urine, or tissue) to provide information for the diagnosis, monitoring, or treatment of a disease or condition. This device does not fit that description.

Device Description
The TandemHeart Veno-Venous Cannula Set consists of two components: a 29 Fr. Dual lumen Veno-Venous Cannula and a 13 Fr. Introducer. The Introducer is designed to accept a standard 0.038 inch guidewire. The TandemHeart Veno-Venous Cannula Set is intended as a single patient, single use, sterile device.
The TandemHeart Veno-Venous Cannula 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. 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 cannula has printed insertion depth markings every 10 centimeters from 10 to 30 cm followed by every 2 centimeters for the remainder of the insert-able length, measured from the distal end. The cannula also has a suture wing that can be used for securing the cannula in place to the patient.
The introducer consists of a tube with a 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 hub at its proximal end to manage introducer insertion and removal from the cannula. 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.

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 Veno-Venous Cannula and the predicate, Medtronic Avalon Elite. 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 Veno-Venous Cannula relative to the Avalon Elite 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 Veno-Venous Cannula are addressed by comparison with both the Avalon elite and a second predicate, the TandemHeart Venous Cannula (K133236). Based on the performance test results and data from the predicate devices, the TandemHeart Veno-Venous Cannula was found to meet established design input requirements and thus to be substantially equivalent to the predicate Avalon Elite Dual Lumen Veno-Venous Cannula.

The TandemHeart Veno-Venous Cannula (Figure 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 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.

Intended Use
The TandemHeart 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.
Comparison of Technological Characteristics
The TandemHeart Veno-Venous Cannula Set and the predicate Avalon (Maquet) Elite Bi-Caval Dual Lumen Catheter (K081820) are both wire-reinforced dual lumen venous cannula. Both kits include an introducer to facilitate placement using a guidewire and fluoroscopy. There are a number of technological differences: 1) the TandemHeart Veno-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 TandemHeart Veno-Venous cannula is co-axial whereas the Avalon Elite predicate is bi-caval; 3) the TandemHeart Veno-Venous Cannula has a 29 Fr outer diameter at the proximal end compared to 27 Fr for the comparable Avalon Elite; 4) the TandemHeart Veno-Venous Cannula is longer than the predicate with greater distance between inlet and outlet to reduce recirculation and to allow improved flexibility in positioning within the venous system; and 5) the TandemHeart Veno-Venous Cannula features a taper from the narrow distal, single lumen portion to the larger diameter, proximal, dual lumen portion that is designed to aid with insertion by gradually dilating the vessel.
Performance Data
Non-clinical performance testing was conducted to demonstrate substantial equivalence of flow characteristics between the TandemHeart Veno-Venous Cannula and the predicate, Medtronic Avalon Elite 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 Veno-Venous Cannula relative to the Avalon Elite 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 Veno-Venous Cannula are addressed by comparison with both the Avalon elite and a second predicate, the TandemHeart Venous Cannula (K133236). Based on the performance test results and data from the predicate devices, the TandemHeart Veno-Venous Cannula was found to meet established design input requirements and thus to be substantially equivalent to the predicate Avalon Elite Dual Lumen Veno-Venous Cannula.
