Intended Use

The COBE® Closed Venous Reservoir Bags With SMAR,T™ are closed, flexible reservoir bags intended to be used as blood reservoirs during adult cardiac surgical procedures requiring extracorporeal support for periods up to six hours.

Device Story

Flexible, closed blood reservoir bags (1200 ml or 1800 ml) used during adult cardiac surgery with extracorporeal support. Inputs include systemic venous and cardiotomy return blood. Features surface-modifying material to improve blood compatibility. VRB 1200 includes rigid backing plate, three-stopcock sampling system, one-way vent valve, and level-sensing magnet for integration with COBE Air Emboli Protection System. VRB 1800 is a simplified version without the rigid plate. Operated by perfusionists/clinicians in surgical settings. Device collects and stores blood, assists in air removal, and provides volume indication. Benefits include improved blood compatibility and integrated air emboli protection.

Clinical Evidence

No clinical data. Evidence consists of bench testing including SEM analysis, mechanical integrity, air challenge, bag shutoff, collapse volume, blood cell damage, and surface-modifying material leaching/compatibility testing, plus ex-vivo blood compatibility testing.

Technological Characteristics

Flexible reservoir bags with surface-modifying material on blood-contact surfaces. VRB 1200 includes rigid backing plate, stopcock sampling system, one-way vent valve, and level-sensing magnet. Single-use, sterile, non-pyrogenic. No electronic components; level sensing is mechanical/magnetic for external system integration.

Indications for Use

Indicated for adult patients undergoing cardiac surgical procedures requiring extracorporeal support for up to six hours.

Regulatory Classification

Identification

A cardiopulmonary bypass blood reservoir is a device used in conjunction with short-term extracorporeal circulation devices to hold a reserve supply of blood in the bypass circulation.

Special Controls

*Classification.* Class II (special controls), except that a reservoir that contains a defoamer or filter is classified into the same class as the defoamer or filter. The device, when it is a cardiopulmonary bypass blood reservoir that does not contain defoamers or blood filters, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

Phone: [phone]

Venous Reservoir Bag COMMON/USUAL NAME:

Cardiopulmonary Bypass Blood Reservoir CLASSIFICATION NAME:

COBE® VRB® 1200™ Closed Venous Reservoir Bag PREDICATE DEVICE:

DEVICE DESCRIPTION:

The COBE® Closed Venous Reservoir Bags With SMAR TT™, Model Numbers VRB® 1200™ and VRB® 1800™ are sterile devices with non-pyrogenic fluid pathways, for single use only, and are not to be resterilized by the user. The devices accomodate both systemic venous and cardiotomy return blood. A surface-modifying material is added to the primary blood contact surfaces of the device to improve the blood compatibility of the materials.

The VRB® 1200™ with SMAR,T consists of the bag with its basic ports (venous inlet, cardiotomy inlet, reservoir outlet, reservoir vent, venous sample ports) along with several additional user features. The reservoir bag is attached directly to a rigid backing plate that contains a three stopcock blood sampling system, a reservoir vent line with a one-way valve, and a front plate that is designed to exert pressure on the bag, squeezing it between the front and back plates to assist in air removal. There is a volume indicator tape on the back plate which provides an indication of the amount of blood in the bag. There is also a level sensing magnet on the outside of the reservoir bag and a sensor in the bracket which allows the VRB® 1200™ with SMAR,T to be used with the COBE® Air Emboli Protection System. The maximum volume of the reservoir bag is 1200 ml.

The VRB® 1800™ with SMAR,T is a simplified version of the VRB® 1200™ with SMAR,T. The VRB® 1800™ with SMAR, T consists of only the bag with its basic ports (venous inlet, cardiotomy inlet, reservoir outlet, reservoir vent, venous sample port, and auxillary ports). It does not have the additional user features listed above for the VRB® 1200™ with SMAR. T. The maximum volume of the reservoir bag is 1800 ml (the reservoir bag is identical to the VRB® 1200™ with SMART, but the maximum volume is greater in the VRB® 1800™ with SMAR, T because it is not attached to the rigid back plate).

## INDICATIONS FOR USE

The COBE® Closed Venous Reservoir Bags With SMAR,T™ are closed, flexible reservoir bags intended to be used as blood reservoirs during adult cardiac surgical procedures requiring extracorporeal support for periods up to six hours.

## STATEMENT OF TECHNICAL CHARACTERISTICS COMPARISON

The COBE® Closed Venous Reservoir Bags With SMAR T™ have the same intended use as the COBE® VRB® 1200™ Closed Venous Reservoir Bag. The only differences between the COBE® Closed Venous Reservoir Bags With SMAR TTM and the currently marketed VRB® 1200™ are 1) the COBE® Closed Venous Reservoir Bags With SMAR T™ contain the surface-modifying material; 2) Model VRB® 1800™ with SMAR,T is a simplified version of the VRB® 1200™, consisting only of the bag with its basic ports.

Biocompatibility testing, in-vitro testing, and ex-vivo testing were performed to demonstrate that the COBE® Closed Venous Reservoir Bags With SMAR, T™ are substantially equivalent to the currently marketed COBE® VRB® 1200™ Closed Venous Reservoir Bag.

In-vitro testing consisted of:

SEM Analysis Mechanical Integrity Air Challenge Bag Shutoff Collapse Volume Blood cell damage Surface-modifying material leaching Surface-modifying material blood compatibility

Ex-vivo testing consisted of:

Surface-modifying material blood compatibility

These data support that the COBE® Closed Venous Reservoir Bags With SMAR, T™ are substantially equivalent to the currently marketed COBE® VRB® 1200™ Closed Venous Reservoir Bag, and the addition of the surface-modifying material does not affect safety and effectiveness.
