Abstract: The present invention relates to a device for securing medical leads in a cranial burr hole, in particular, for securing a brain stimulation lead within such a burr hole. The device includes a circular socket element adapted to be secured within a burr hole of the skull of a patient, the circular socket element having a through lead passage arranged to have the lead pass therethrough, the lead passage including passage walls including at least one resilient partition wall extending from an inner wall of the circular socket element, and the circular socket element having at least one inner compartment delimited by the partition wall.

Abstract: A directional valve for a breathing apparatus, such as an anaesthetic machine, has a valve seat with a valve port and a valve plate resting loosely on a valve seat. The valve plate has a soft, pliant area on its surface in contact with the valve seat and a relatively rigid area across the valve port.
