Disclosed herein are systems, devices, and methods for accessing a subdural space. In some embodiments, an apparatus may comprise a shaft configured to be slidably disposed within a lumen of a catheter. The shaft may be configured to be advanced distally from a distal end of the catheter and into a blood vessel of a subject. The shaft may include a perforating tip including an energy element configured to generate radiofrequency energy to form an opening through a wall of the blood vessel and dura of the subject and into an extravascular space of the subject. A curved section may be configured to be radially constrained within the lumen of the catheter and to curve toward the wall of the blood vessel and the dura upon exiting the lumen of the catheter such that the energy element is positioned to form the opening.
