Abstract: A subdural drainage device includes a subdural drainage housing defining a drainage passageway. The drainage passageway has a A subdural drainage device includes a subdural drainage housing defining a drainage passageway. The drainage passageway has a lower opening configured to connect to a subdural space of a patient and an upper opening. A blockage removal unit is in the housing, and the blockage removal unit has an end portion that is configured to reduce or remove blockages adjacent the lower opening of the drainage passageway that is movable between a retracted position in which the end portion is in the subdural drainage housing and an extended position in which the end portion of the blockage removal unit extends away from the subdural drainage housing via the lower opening of the drainage passageway. At least one side delivery port is in the housing and in fluid communication with the drainage passageway.

Abstract: A subdural drainage system includes (a) a subdural drainage device having an opening formed therethrough, said subdural drainage device having an upper portion, a body portion, and a lower portion; (b) a housing having an upper portion and lower portion, with said housing connected to said subdural drainage device; said housing movable between (i) a first configuration and (ii) a second configuration; and (c) a stylet positioned inside said housing, said stylet having an upper portion and a lower portion and configured such that said stylet is moved between (i) a withdrawn position with said stylet withdrawn from a portion of said subdural evacuation port device, and (ii) an extended position with said stylet extending through said subdural drainage device such that blockages are disrupted in the subdural drainage device when said housing is moved between said first and second housing configurations; and (d) an external drain opening formed on either said subdural drainage device or said housing.
