Intended Use

The Venous Return Cannula is indicated for use in drainage of the superior and inferior vena cava during cardiopulmonary bypass surgery for up to six hours.

Device Story

Venous Return Cannulae are single-use, sterile, non-pyrogenic devices used during cardiopulmonary bypass surgery. The device consists of an open-lumen PVC polymer tube with wire reinforcement in the distal section and a lighthouse-shaped tip. It is inserted into the superior and inferior vena cava to facilitate venous blood drainage from the vessel into the cardiopulmonary bypass circuit. The proximal end is clear and non-reinforced to allow for clamping and connection to standard bypass tubing. The device is operated by a surgeon in an operating room environment. The primary benefit is the effective diversion of venous blood during bypass procedures. The device design was updated to replace PVC materials containing phthalates (DEHP and DnHP) with alternative PVC materials.

Clinical Evidence

No clinical data was provided. Substantial equivalence is supported by non-clinical verification and validation testing, including visual inspection, connector pull tests, clamp tests, flow rate/pressure drop analysis, kink tests, collapse resistance, blood trauma characterization, and biocompatibility testing in accordance with ISO 18193.

Technological Characteristics

Single-use, sterile, non-pyrogenic venous drainage cannula. Materials: PVC polymer (phthalate-free). Features: Wire-reinforced distal section, lighthouse-shaped tip, clear non-reinforced proximal section for clamping. Dimensions: 16-36 French sizes. Sterilization: Ethylene oxide. Testing standards: ISO 18193.

## IV. Device Description

Venous Return Cannulae are single-use, non-toxic, non-pyrogenic fluid path devices, supplied sterile and individually packaged.

The devices are composed of the cannula: an open lumen PVC polymer tube incorporating wire reinforcement in distal section.

The distal end of the cannula has a lighthouse-shaped tip, allowing the venous blood to flow from the vessel into the cannula. The clear proximal section is not reinforced to allow clamping; the proximal end typically does not have any pre-mounted connector and can accommodate a barbed connector for standard cardiopulmonary bypass tubing (¼"; ½" or 3/8" diameter).

The following cannula models are available:

## V. Indications for Use

The Venous Return Cannula is indicated for use in drainage of the superior and inferior vena cava during cardiopulmonary bypass surgery for up to six hours.

## VI. Summary of Technical Characteristics

The Venous Return Cannulae have the same fundamental technological characteristics, principles of operation and control mechanisms as the predicate devices.

The PVC material in the body and tip of the Venous cannulae was changed with another PVC material in order to remove the phthalates (DEHP and DnHP) used as plasticizers currently present in the device.

The devices are ethylene oxide sterilized and have a non-pyrogenic fluid path. They are for single use only.

## VII. Non-Clinical Performance Data

Sorin Group Italia S.r.l. has conducted extensive verification and validation testing of the Venous Return Cannulae; specifically, the following tests in accordance with ISO 18193 were carried out:

- Visual inspection
- Connector testing 180° pull test
- Cannula clamp test
- Blood pathway integrity
- Flow rate and pressure drop through cannulae
- Cannula kink test
- Label legibility
- Drainage cannula collapse resistance
- Cannula integrity
- Pull strength
