The polyurethane-coated Delta Valves, polyurethane-coated CSF-Flow Control Valves, Contoured, and Burr Hole are components of polyurethane shunt systems designed for use in shunting cerebrospinal fluid from the ventricles of the brain into the right atrium of the heart or to the peritoneal cavity. The Polyurethane shunt and shunt components are designed to eliminate patient exposure to silicone elastomer.
The polyurethane-coated Delta Valve minimizes the excessive reduction of intraventricular pressure and volume due to excessive drainage of CSF, which may be caused by the siphoning effect of hydrostatic pressure of the distal catheter. The siphon effect may be created by the elevation of the ventricular catheter with respect to the distal catheter (i.e., when the patient sits, stands, or is held erect).
A Ventricular Catheter manufactured of Polyurethane tubing. A Flow Control Valve manufactured of a Polypropylene base and a silicone elastomer housing which incorporates a Tecoflex elastomer resin, polyurethane coating. A Cardiac/Peritoneal Catheter manufactured of Polyurethane tubina.
This document is a 510(k) summary for a medical device (Medtronic PS Medical Polyurethane Shunt) and a clearance letter from the FDA. It does not contain any information about acceptance criteria, study details, or performance metrics that would typically be found in a clinical study report or a detailed device performance study.
Therefore, I cannot provide the requested information. The provided text primarily focuses on:
- Device Description: What the device is made of and its components.
- Intended Use: The purpose of the device (shunting CSF).
- Technological Comparison: Statement of substantial equivalence to predicate devices based on materials, intended uses, performance characteristics, and design specifications. This implies that the device is similar to existing devices known to be safe and effective, rather than presenting new performance data.
- FDA Clearance: The letter confirming FDA's determination of substantial equivalence, allowing the device to be marketed.
In summary, the provided text does not contain the information necessary to describe acceptance criteria or the study that proves the device meets those criteria.

Dear Mr. Henderson:
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 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 requirement, 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 regulatory 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.

This letter will allow you to begin marketing your device as described in your 510(k) Frido reter notification. The FDA finding of substantial equivalence of your device to a premainverleted predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4595. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its internet address "http://www.fda.gov/cdrh/dsmamain.html".

§ 882.5550 Central nervous system fluid shunt and components.
(a)
Identification. A central nervous system fluid shunt is a device or combination of devices used to divert fluid from the brain or other part of the central nervous system to an internal delivery site or an external receptacle for the purpose of relieving elevated intracranial pressure or fluid volume (e.g., due to hydrocephalus). Components of a central nervous system shunt include catheters, valved catheters, valves, connectors, and other accessory components intended to facilitate use of the shunt or evaluation of a patient with a shunt.(b)
Classification. Class II (performance standards).
