Abstract:
1. A method of removing solid matter disposed within brain tissue of a subject and for controlling bleeding once the solid matter has been removed, the method comprising: (a) securing a cranial anchor to an opening in a skull of the subject, the anchor defining an anchor passage running therethrough; (b) introducing a channel member through the anchor passage to displace brain tissue and expose the solid matter, wherein the channel member has a first end and a second end and defines a working channel passing through the channel member from the first end to the second end; (c) removing the solid matter via the working channel to create a cavity defined by the brain tissue that surrounded the solid matter prior to removal of the solid matter; (d) inserting a catheter defining a lumen into the working channel; (e) introducing a flowable hemostat through the lumen directly into the cavity to contact the brain tissue that surrounded the solid matter prior to its removal; (f) introducing an inflatable balloon into the working channel; and (g) inflating the balloon to compress the hemostat against brain tissue defining the cavity to stop bleeding from blood vessels disposed within the brain tissue defining the cavity.
