#### Submitter Information:

This Premarket Notification is submitted by:

Garry A. Courtney, MBA, RAC Telephone: [phone], Ext. 7420

This Premarket Notification is submitted on behalf of:

Ashitaka Factory of Terumo Corporation 150 Maimaigi-cho Fujinomiya city, Shizuoka Pref. Japan 418-0015

#### Device Names:

| Proprietary Name: | CAPIOX® SX10 Hardshell Reservoir |
|-------------------|---------------------------------------------------|
| Common Name: | Blood Reservoir |
| Classification: | CPB Reservoirs are classified as Class II devices |

### Predicate Device:

The CAPIOX® SX10 Hardshell Reservoir is substantially equivalent in intended use, materials, design, technology and principles of operation, and performance to the CAPIOX® SX 10 Hardshell Reservoir that was cleared for marketing under Premarket Notification K991973.

#### Intended Use:

The CAPIOX® SX10 Hardshell Reservoir is a hardshell reservoir used to store blood during extra-corporeal circulation from both the venous line and the cardiotomy line during cardiopulmonary bypass procedures lasting up to 6 hours. The reservoir contains filters to remove particulate matter and defoamers to facilitate air bubble removal.

The Hardshell Reservoir may also be used with vacuum-assisted venous return procedures during cardiopulmonary bypass procedures lasting up to 6 hours.

#### Principles of Operation and Technology:

The CAPIOX® SX Hardshell Reservoir is used as a blood storage device during cardiopulmonary bypass procedures. Venous blood enters the reservoir via gravity, or by way of external vacuum that may be applied to the reservoir.

Venous blood that is drawn from the patient enters the device through the venous blood inlet port. The blood passes through a defoamer to remove air from the blood and through a filter for removal of particulates.

{1}------------------------------------------------

Blood may also be suctioned into the reservoir from the cardiotomy field. This blood enters the device through the cardiotomy blood suction ports that are located on the lid assembly. As with the venous blood, the cardiotomy blood passes through a defoamer to facilitate air removal, and then through a filter for removal of particulates. Air is also removed from the blood due to its tendency to rise within a liquid medium.

Blood exits the device via gravity through the blood outlet port and is pumped through the remaining cardiopulmonary bypass circuit.

## Design and Materials:

The design of the CAPIOX® SX10 Reservoir consists of a hard casing reservoir containing blood filters. It has a rotatable venous blood inlet port that permits minimizing tubing lengths, which could result in lower circuit priming volumes. The total capacity of the reservoir is 3000 mL.

The CAPIOX® SX10 Hardshell Reservoir contains a defoamer and a screen filter in the venous blood inlet section. The defoamer resides in the upper part of the reservoir, thus permitting blood to reside in the lower-section of the reservoir.

The cardiotomy section of the SX10 Reservoir contains a defoamer and a "sock-like" filter to facilitate air removal and the removal of particulates from suctioned blood entering the reservoir.

The generic materials used in the CAPIOX® RX Hardshell Reservoir are polycarbonate. polypropylene, polyethylene terephthalate, silicone, polyvinyl chloride, polyurethane, nylon, stainless steel, ceramic, and polymer coating solutions.

## Performance Evaluations:

The performance of the CAPIOX® SX10 Hardshell Reservoir is substantially equivalent to the performance of the predicate (unmodified) device. The following tests were conducted to demonstrate equivalence in performance:

- Filter Defoaming ●
- Pressure Drop .
- Filtration Efficiency ●
- . Effects Upon Cellular Blood Components
- Pressure Integrity Testing ●

{2}------------------------------------------------

## Substantial Equivalence Comparison:

The CAPIOX® SX10 Hardshell Reservoir is substantially equivalent to the predicate SX10 Hardshell Reservoir device as follows:

Intended Use: The modified SX10 Hardshell Reservoir and the predicate (unmodified) SX10 Hardshell Reservoir share the same exact intended uses. Each is used to store blood during extra-corporeal circulation from both the venous line and the cardiotomy line during cardiopulmonary bypass procedures lasting up to 6 hours.

Fach of the reservoirs (modified and unmodified) contains filters to remove particulate matter and defoamers to facilitate air bubble removal.

The (modified) SX10 Hardshell Reservoir and the (unmodified) SX10 Hardshell Reservoir each may also be used with vacuum-assisted venous return procedures during cardiopulmonary bypass procedures lasting up to 6 hours.

Principles of Operation and Technology: The (modified) SX10 Reservoir and the predicate SX Reservoirs each utilize gravity and/or vacuum to draw blood into the device. and each has filters and defoamers that facilitate the removal of particulate and air, respectively. Air is also removed from the circulating blood within both devices due to the tendency of air to rise within a liquid medium.

Design and Materials: The design and the materials of the (modified) SX10 Reservoir and the (unmodified) SX10 Reservoir are essentially the same. Differences include a "socklike" cardiotomy filter in the modified device vs. a "pleated" filter design in the predicate device; and the addition of channeling groves at the base of the reservoir in the modified device that are not present in the unmodified predicate device.

The materials used in the two devices are identical except that the modified device contains Terumo's X-Coating polymer, which is not present on the unmodified SX10 Hardshell Reservoir. The X-Coating polymer has been applied to multiple Terumo products that have been reviewed and cleared for marketing by the United States Food and Drug Administration.

Performance: Comparison studies of the performance of the (modified) SX10 Hardshell Reservoir and the predicate SX10 Reservoir were conducted. The comparisons demonstrated that there were no clinically significant performance differences between the devices.

## Substantial Equivalence Summary:

In summary, the (modified) CAPIOX® SX10 Hardshell Reservoir and the predicate (unmodified) CAPIOX® SX10 Reservoir are substantially equivalent in intended use, principles of operation and technology, design and materials, and performance. Any noted differences between the devices do not raise new issues of safety and effectiveness.
