Intended Use

The AFFINITY® 38 µ Arterial Blood Filter with Trillium™ Biopassive Surface is indicated for use in cardiopulmonary bypass procedures for the removal of particulate and gaseous microemboli.

Device Story

Single-use arterial blood filter for extracorporeal circuits during cardiopulmonary bypass surgery. Device removes particulate and gaseous microemboli from blood. Primary modification involves application of non-leaching Trillium™ biopassive surface coating to blood contact surfaces. Used in clinical settings by perfusionists or surgical staff. Output is filtered blood returned to patient. Biopassive coating intended to improve hemocompatibility.

Clinical Evidence

Bench testing only. In vitro testing included analysis of coating characteristics, physical characteristics, and performance characteristics to demonstrate substantial equivalence to predicate devices.

Technological Characteristics

Arterial blood filter with Trillium™ biopassive surface coating. Single-use. Mechanical filtration principle. No software or electronic components.

Indications for Use

Indicated for patients undergoing cardiopulmonary bypass procedures requiring removal of particulate and gaseous microemboli.

Regulatory Classification

Identification

A cardiopulmonary bypass arterial line blood filter is a device used as part of a gas exchange (oxygenator) system to filter nonbiologic particles and emboli (blood clots or pieces of foreign material flowing in the bloodstream which will obstruct circulation by blocking a vessel) out of the blood. It is used in the arterial return line.

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Guidance for Cardiopulmonary Bypass Arterial Line Blood Filter 510(k) Submissions.”

Predicate Devices

• AFFINITY® 38 µ Arterial Blood Filter (K952532)
• AFFINITY® Hollow Fiber Oxygenator with Trillium™ Biopassive Surface (K973760)

# STATEMENT OF TECHNOLOGICAL CHARACTERISTICS COMPARISON

Information regarding technological characteristics comparison is provided in the following section, "Determination of Substantial Equivalence".

## DETERMINATION OF SUBSTANTIAL EQUIVALENCE

This "SPECIAL 510(k)" is being submitted for a modification to the AFFINITY® 38 u Arterial Blood Filter. The modification to the current AFFINITY® 38 u Arterial Blood Filter is to coat the primary blood contact surfaces with Trillium™.

The AFFINITY® 38 µ Arterial Blood Filter with Trillium™ Biopassive Surface is being compared to the following Marketed Devices:

- . AFFINITY® 38 µ Arterial Blood Filter (K952532)
- AFFINITY® Hollow Fiber Oxygenator with Trillium™ Biopassive Surface . (K973760)

The AFFINITY® 38 u Arterial Blood Filter with Trillium™ Biopassive Surface Trillium™ has the same indications statement and intended uses as the:

- AFFINITY® 38 u Arterial Blood Filter (K952532) .
The AFFINITY® 38 µ Arterial Blood Filter with Trillium™ Biopassive Surface has "no new technological characteristics (e.g., materials and manufacturing processes)" from the AFFINITY® 38 µ Arterial Blood Filter. The technological characteristic is solely the coating material of the blood pathway:

- Trillium™ .
The technological characteristic of the Trillium™ Biopassive Surface is common to other medical devices (hollow fiber oxygenators) currently in commercial distribution as follows:

- AFFINITY® Hollow Fiber Oxygenator with Trillium™ Biopassive Surface . (K973760)
This technological characteristic "could affect the safety and effectiveness of the device". However, these "technological characteristics do not raise new types of safety or effectiveness questions". In addition, "there are acceptable scientific methods which exist for assessing effects of these new technological characteristics".

"Performance data to assess the effects of these new technological characteristics" has been performed. These "performance data demonstrate" that the AFFINITY® 38 u Arterial Blood Filter with Trillium™ Biopassive Surface is
