The present invention provides minimally invasive subdural evacuating systems and methods of use thereof. The subdural evacuating systems include a cutting component and a rod component, wherein the rod component provides an external physical indicator that the surface of the dura mater has been reached, permitting the cutting component to accurately pierce the dura mater with minimal to no risk of damaging any adjacent anatomy.

Minimally invasive subdural evacuating system

The present invention provides expandable devices and insertion tools for deploying the expandable devices. The expandable devices are capable of increasing in height and width when expanded from a closed configuration to an open configuration to occupy a larger volume and to present a larger surface area. The expandable devices are lockable and are capable of rigidly occupying a space after expansion. In some embodiments, the expandable devices are useful as interbody devices for spinal fusions.

Expandable device

A declogging assembly () is configured for use with a suction conduit (). The suction conduit has a head () at a first end () and a vacuum tube connection () at a second end (). The assembly includes a body (). The body defines a first aperture (), a second aperture (), and a third aperture (). The assembly also includes a plug () disposed within the body (). The plug has a surface () configured to contact the head () of the suction conduit () so as to move the plug from a first position, in which the first aperture () is in fluid communication with the second aperture (), to a second position, in which the first aperture () is in fluid communication with the third aperture (). The assembly () also includes a biasing member () configured to bias the plug into the first position.
