Ommaya Reservoir

An Ommaya Reservoir is a small, adjustable device implanted under the scalp, typically used for delivering medication directly into the brain or collecting cerebrospinal fluid (CSF). It consists of a dome-shaped bag connected to a catheter that reaches into the fluid-filled space around the brain and spinal cord. This setup allows healthcare providers to administer chemotherapy, antibiotics, or to draw fluid for testing without repeatedly performing invasive procedures like lumbar punctures. It is commonly used in patients with brain tumors or certain infections, providing a safer and more comfortable way to manage treatment and diagnosis.
