X-Coated CAPIOX® SX25 and SX18 Hollow Fiber Oxygenators The with/without Detachable Hardshell Reservoirs are used to exchange gases with without and a gaseous environment to satisfy the gas exchange needs of a patient during cardiopulmonary bypass surgery for periods up to 6 hours.

The integral heat exchanger is used to warm or cool blood or perfusion fluid as it flows through the device.

(detachable) hardshell reservoir is used to store blood during The extracorporeal circulation from both the venous line and the cardiotomy line. The reservoir contains a venous section that is comprised of a filter and defoamer to facilitate air bubble removal. The cardiotomy section of the reservoir contains a filter to remove particulate matter and a defoamer to facilitate air bubble removal.

The X-Coat is a polymer coating that is applied to blood contacting surfaces of the oxygenator to reduce the adhesion of platelets to the surfaces of the device.

Device Description

X-Coated CAPIOX® SX25 and SX18 Hollow Fiber Oxygenators with/without Detachable Hardshell Reservoirs. The device is used to exchange gases with a gaseous environment to satisfy the gas exchange needs of a patient during cardiopulmonary bypass surgery. It includes an integral heat exchanger to warm or cool blood or perfusion fluid. The detachable hardshell reservoir stores blood and contains filters and defoamers to remove air bubbles and particulate matter. The device has an X-Coat polymer coating on blood contacting surfaces to reduce platelet adhesion.

AI/ML Overview

The provided text is a summary of generic safety and effectiveness issues for oxygenators and defoamers, likely from a regulatory submission (indicated by "K993772"). It does not describe an acceptance criteria for a specific device, nor does it contain a study proving a device meets acceptance criteria.

Therefore, I cannot extract the requested information. The document lists potential causes for various problems related to these devices, drawing from medical databases and literature, but it does not present a structured study with defined acceptance criteria and performance data for a particular device.

To fulfill your request, I would need a document that presents:

Specific, quantifiable acceptance criteria for a particular oxygenator or defoamer.
Performance data from a study designed to evaluate that device against those criteria.

Dear Mr. Courtney:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in requlatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
