The ProtekDuo Veno-Venous Cannula is a single use dual lumen cannula, which provides both venous drainage and reinfusion of blood via the jugular vein, that is indicated for use in adult patients with acute requiring Veno-Venous Extracorporeal Membrane Oxygenation, where other available treatment options have failed and continued clinical deterioration is expected or the risk of death is imminent.

Each ProtekDuo Veno-Venous Cannula Set includes a dual lumen cannula and an introducer. The introducer is designed to accept a standard 0.038-inch guidewire. The ProtekDuo Veno-Venous Cannula Sets are intended as single patient, single use, sterile devices. Each ProtekDuo Veno-Venous Cannula consists of two (2) distinct lumens, each made of polyurethane 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 is the smaller diameter lumen with six (6) 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 set-up 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 two suture wings that can be used for securing the cannula in place to the patient. The cannulas also have printed insertion depth markings measured from the distal tip. Each introducer consists of a tube and 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 polyvinyl chloride material for visualization under fluoroscopy.

The MC3 Crescent™ Jugular Dual Lumen Catheter is a single use, dual lumen catheter that provides both venous drainage and reinfusion of blood via the jugular vein and is indicated for use in adult and pediatric patients with acute respiratory failure requiring Veno-Venous Extracorporeal Membrane Oxygenation, where other available treatment options have failed and continued clinical deterioration is expected or the risk of death is imminent.

The MC3 Jugular Dual Lumen Catheters are dual lumen catheters supplied with an introducer to facilitate wire guided placement into the vasculature via percutaneous (Seldinger type) vascular access methods. The introducer is designed to follow a prepositioned standard guide wire (not included) or obturator (blunt end closed tip introducer) when following a surgical placement. The catheter is wire reinforced for flexibility and kink-resistance and includes depth marks. Both the introducer and catheter are made of radiopaque materials and the catheter also includes tantalum radiopaque markers at the infusion port, proximal and distal drainage holes, and the catheter tip. The catheter body contains an integrated suture site for use during securement. An optional suture collar is provided and can be used for supplemental securement only. A dilator is also included. The dilators are the same diameter of the catheter and are designed to be used for dilation of the vessel. These catheters are provided in a variety of sizes ranging from 13Fr (8.9 cm insertable length) to 32Fr (34 cm insertable length).

The MC3 Jugular Dual Lumen Catheter is a single use dual lumen catheter, which provides both venous drainage and reinfusion of blood via the jugular vein, that is indicated for use in patients with acute respiratory failure requiring Veno-Venous Extracorporeal Membrane Oxygenation, where other available treatment options have failed and continued clinical deterioration is expected or the risk of death is imminent.

The MC3 Jugular Dual Lumen Catheters are bi-caval dual lumen catheters supplied with an introducer to facilitate wire guided placement into the vasculature via percutaneous surgical methods (Seldinger type approach). The introducer is designed to follow a prepositioned standard 0.038" (0.97 mm) or 0.035" (0.89 mm) guide wire (not included). The introducer hub provides an area for grasping the introducer during insertion and when fully seated, indicates that the introducer is fully inserted. The catheter is wire reinforced for flexibility and kink-resistance and includes depth marks. Both the introducer and catheter are made of radiopaque materials and the catheter also includes tantalum radiopaque markers at the infusion port, proximal and distal drainage holes, and the catheter tip. The catheter body contains an integrated suture site for use during securement. An optional suture collar is provided and can be used for supplemental securement only. A dilator is also included. The dilators are the same diameter of the catheter and are designed to be used for dilation of the vessel. The catheters remain intact throughout the duration of use and withstand the forces associated with insertion, securement, connection to perfusion line, clamping, blood pressures, and removal.

The MC3 26 Fr. QuickFlow™ Dual Lumen Catheter is a single use dual lumen catheter, which provides both venous drainage and reinfusion of blood via the femoral vein, that is indicated for use for up to 72 hours in patients with acute respiratory failure requiring partial Veno-Venous Extracorporeal Membrane Oxygenation (full hemodynamic support is not required and predicted flows needed to maintain adequate oxygenation do not exceed 31/min) where other available treatment options have failed and continued clinical deterioration is expected or the risk of death is imminent. The MC3 28 Fr. QuickFlow™ Dual Lumen Catheter is a single use dual lumen catheter, which provides both venous drainage and reinfusion of blood via the femoral vein, that is indicated for use for up to 72 hours in patients with acute respiratory failure requiring partial Veno-Venous Extracorporeal Membrane Oxygenation (full hemodynamic support is not required and predicted flows needed to maintain adequate oxygenation do not exceed 3.5l/min) where other available treatment options have failed and continued clinical deterioration is expected or the risk of death is imminent.

The MC3 QuickFlow Dual Lumen Catheters are dual lumen catheters supplied with an introducer to facilitate wire guided placement into the vasculature by normal access techniques. The introducer is designed to follow a pre-positioned standard 0.038" (0.97 mm) or 0.035" (0.89 mm) guide wire (not included). The catheter is wire-reinforced for flexibility and kink-resistance and includes depth marks. Both the introducer and catheter are made of radiopaque materials and the catheter has radiopaque markers at the tip and most proximal set of drainage holes. The devices are comprised of two separate thin-walled catheters made of silicone and polyurethane polymer and reinforced with a spring wire. The dual lumen design involves two catheters of different diameters joined together in a co-axial configuration. An arrangement of side holes in the outer (drainage) catheter allows for egress of blood. An open tip on the inner (return) catheter allow s for blood ingress. Unreinforced tube extensions with barbed connectors, allowing clamping and connection to the extracorporeal circuit, are joined to the wye junction. A tapered tip introducer is included to facilitate placement of the catheter into the blood vessel over a standard guide wire (not included). Securement of the device may be accomplished via a groove designed in the Y-connector to accept a suture and a suture around a 3/8" barb connector.
