Abstract
Disclosed is a medical device comprising an external, flexible shell forming a fluid reservoir and housing a non-obstructive, self-regulating valve, having a folded membrane which forms a slit-like opening in a chamber. An inlet tube in communication with the chamber through an aperture in the membrane extends outwardly through an opening in the shell. The free end of the inlet tube, including holes, is in communication with the brain or cranial vault. There is an outlet tube in communication with the reservoir. The free end of the outlet tube, also including holes, is in communication with either the heart or the abdomen. If the outlet tube is in communication with the abdomen the preferred configuration of the free end includes rigid fins. Also disclosed is a method of using this device to treat hydrocephalus and a process for making the device.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
