Device Story

Sterile, disposable pediatric arterial filters; D731 (20 micron) and D733 (40 micron). Used in cardiopulmonary bypass circuits; flow rates up to 5.0 L/min. Function: trap/remove gaseous emboli and particulate debris from arterial line perfusate. Operated by perfusionists/clinicians in surgical settings. Output: filtered blood returned to patient. Benefit: reduction of embolic/particulate load during bypass. Design identical to predicate; increased flow rate capacity.

Clinical Evidence

Bench testing only. In vitro studies conducted per FDA guidance (Nov 29, 2000) on aged devices (up to 5 years). Tests included structural/mechanical integrity, blood side pressure drop, flow rate capacity, hemolysis/cell depletion, filtration efficiency, and air handling. Results demonstrated performance comparable to predicate devices.

Technological Characteristics

Materials: same as predicate (no new materials). Filtering media: 20 or 40 micron pore size. Energy source: none (passive). Connectivity: none. Sterilization: ethylene oxide. Fluid path: non-pyrogenic. Form factor: pediatric arterial filter. Flow rate: up to 5.0 LPM.

Indications for Use

Indicated for use in the arterial line of extracorporeal circuits during cardiopulmonary bypass procedures to remove gaseous emboli and particulate debris. Contraindicated for use longer than 6 hours.

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.”

Cardiopulmonary Bypass Arterial Line Blood Filter

D731 MICRO 20: Dideco D731 Micro 20 Pediatric Arterial Filter with 20 micron screen and D733 MICRO 40: Dideco D733 MICRO 40 Pediatric Arterial Filter with 40 micron screen (hereafter referred to as D731 and D733 respectively) (K945198).

### DEVICE DESCRIPTION:

The D731 MICRO 20 and D733 MICRO 40 are sterile, non-pyrogenic disposable filters for use in arterial line of the cardiopulmonary bypass circuit with the flow rate not exceeding 5.0 liters/minutes. The D731 MICRO 20 and D733 MICRO 40 are Pediatric Arterial Filters with 20 and 40 micron filter screens designed to remove potentially harmful gaseous emboli, aggregated blood constituents, and particulate debris greater than 20 and 40 microns respectively from the arterial line perfusate. The maximum blood flow rate has been increased to 5.0 liters/minute.

## INDICATION FOR USE:

The Dideco D731 MICRO 20 with 20 micron screen and the Dideco D733 MICRO 40 with 40 micron screen are recommended for use in the arterial line of the extracorporeal circuit during any procedure that requires cardiopulmonary bypass. The filters are used to trap and remove gaseous emboli as well as particulate debris that maybe introduced through the arterial line. The device should not be used longer than b hours. Contact with blood for longer periods is not advised.

# TECHNOLOGICAL CHARACTERISTICS:

The D731 MICRO 20 and the D733 MICRO 40 have the same design features, operating principles and control mechanisms when compared to the D731/D733 predicate devices. The D731 MICRO 20 and the D733 MICRO 40 utilize the same materials, filtering media with the same filter pore size (20 and 40 micron respectively) and the same main blood flow path as the predicate devices.

The D731 MICRO 20 and of the D733 MICRO 40 are, with the exception of the increase of the maximum blood flow rate up to 5.0 LPM, identical to the current MICRO Pediatric series predicate devices. No change of the intended use has been made as result of the extension of the maximum blood flow rate up to 5.0 LPM for both the D731 MICRO 20 and D733 MICRO 40. Both devices share the identical manufacturing process. The arterial filters are ethylene oxide sterilized and have a nonpyrogenic fluid path. They are tor single use only.

# BIOCOMPATIBILITY TEST RESULTS:

A complete battery of tests were carried out in accordance with the requirements of ISO 10993-1:1995 and the FDA May 1, 1995 Memorandum on the use of the ISO 10993 standard for biocompatibility testing on the raw materials. Testing was performed on the D731 MICRO 20 and of the D733 MICRO 40 (accelerated aging). The devices were aged up to five years and tested for Hemolysis, Cytotoxicity, In taxes Systemic Toxicity and Mutagenicity, Sterlily, Pyrogenicity and ETO residuals. Package integrity testing was also conducted. The results of the testing met established specifications. No new materials are used in the Pediatric arterial filter as compared to the predicate devices. This 510(k) cross references biocompatibility data previously submitted in D731 MICRO 20 Dideco Pediatric Arterial Filter with 20 micron screen and D733 MICRO 40 Dideco Pediatric Arterial Filter with 40 micron screen 510(k) (K945198).

### IN VITRO TEST RESULTS:

In viro testing was carried out in accordance with the relevant requirements of "Guidance for Cardiopulmonary Bypass Arterial Line Blood Filter 510(k) Submission" Final Guidance for Industry Cated November 29, 2000. These data demonstrate substantial equivalence with the predicate devices and show that the devices are compliant with safety and effectiveness requirements. The device was aged up to 5 years and tested for structural integrity, mechanical integrity, blood side pressure drop, filter flow rate capacity, in vitro hemolysis/cell depletion, filtration efficiency and air handling characteristics. For comparative purposes all tests were performed on sterilized aged devices comparing the D731 MICRO 20 operated at 3.0 LPM vs. the D733 predicate device operated at 5.0 LPM and D731 MCRO 40 operated at 3.0 LPM vs. D733 predicate device operated at 5.0 LPM when applicable. The results of these person net established specifications.

The results of the study showed that the device characteristics of the D731 MICRO 20 vs. D731 predicate device and D733 MICRO 40 vs. D733 predicate device were comparable.

#### CONCLUSIONS:

The results of in vitro studies demonstrate that the D731 MICRO 20 and D733 MICRO devices perform in a manner substantially equivalent to the predicate devices. Biocompatibility and functional tests demonstrate that their performance is equivalent to the D731 and D733 predicate devices, according to their intended use. Additional testing has demonstrated the effectiveness of production techniques assuring the the newborn-infant arterial filters are sterile and non-pyrogenic.
