US Patent:

61285218, Oct 3, 2000

Filed:

Jul 10, 1998

Appl. No.:

9/113946

Inventors:

Dominic P. Marro - North Andover MA
Thomas T. Washburn - Concord MA
Denis E. LaBombard - Georgetown MA

Assignee:

Physiometrix, Inc. - N. Billerica MA

International Classification:

A61B 50478

US Classification:

600383

Abstract:

This invention defines a system for monitoring the brain activity of a human patient in order to monitor a patient's brain electrical activity. The system uses a plurality of receptors which are mounted in predetermined anatomical positions on the patient's head. The receptors are secured by adhesive foam patches. The appliance fits snugly to the head with the aid of self-adjusting strap that carry imbedded electrical circuitry for the receptors. Electrical connectivity in locations where scalp hair is most likely to be present is improved by the use of braille-tip electrodes fitted with large gel reservoirs.

US Classification:

600383

Abstract:

This invention defines a system for monitoring the brain activity of a human patient under anesthesia in order to determine the patient's level of consciousness. The system uses a plurality of receptors which are mounted in predetermined anatomical positions on the patient's head. The receptors are secured by adhesive foam patches. The appliance fits snugly to the head with the aid of self-adjusting strip that carry imbedded electrical circuitry for the receptors. Electrical connectivity in locations where scalp hair is most likely to be present is improved by the use of braille-tip electrodes fitted with large gel reservoirs.

International Classification:

A61M 25/01
C12N 15/861
A61M 25/02

Abstract:

Fluid delivery systems and methods of delivering an agent and treating a disorder are disclosed that include a subcutaneously implantable port having a body defining a chamber with an open top and a delivery opening and a septum coupled to the body to extend over the open top of the chamber. The systems and methods can further include an intrathecal catheter having an proximal end configured to be coupled to the port and fluidly coupled to the delivery opening of the chamber and a plug having a body with a passage to receive the intrathecal catheter therethrough. The plug can be configured to be inserted into the fascia to protect against leakage of cerebrospinal fluid.
