Devices, systems and methods for protecting the brain in craniectomy patients

An SoT prevention system, comprising:

• a cap body,
• wherein the cap body includes electroactive material for sensing a physical magnitude relating to a shape of a skin flap;
• at least one wearable inertial sensor adapted and disposed to sense at least one characteristic relating to patient posture and/or patient movement and to output a signal relating to the sensed patient posture and/or movement;
• a pump that is in fluid communication with a cavity formed by the cap body and overlaying the skin flap;
• at least one memory;
• and
• at least one processor configured to execute instructions stored in the at least one memory for controlling, based on outputs provided by the electroactive material and the at least one wearable sensor, the pump for preventing or reducing SOT.

A cranial cap, adapted for covering, at least partially or fully, a skin flap of a patient's head having undergone a craniectomy, the cranial cap comprising:

• a cap body;
• a flexible sheet adaptable to adhere to the head;
• wherein the cap body and the flexible sheet are sealed to form a fluid-tight cavity;
• a tubing connector port for removably bringing a pump in fluid communication with the cavity such to enable controlling fluid pressure in the cavity;
• and
• at least one wearable sensor adapted and disposed to sense at least one characteristic relating to
• a) a skin flap shape;
• and
• b) patient posture and/or patient movement
• for providing at least one sensor output descriptive of or relating to the at least one sensed characteristic.

A cranial cap, adapted for covering, at least partially or fully, a skin flap of a patient's head having undergone a craniectomy, the cranial cap comprising:

• a cap body;
• wherein the cap body defines a rim that is configured for sealingly engaging with the patient's head to create a fluid-tight cavity that is confined by the cap body and the underlining skin flap;
• a tubing connector port for removably bringing a pump in fluid communication with the cavity such to enable controlling fluid pressure in the cavity;
• and
• at least one sensor adapted and disposed to sense:
• a) at least one characteristic relating to a skin flap shape;
• and
• b) patient posture and/or patient movement
• for providing at least one sensor output descriptive of or relating to the at least one characteristic.
