Customizable Skull Prosthesis for Protection Following Craniectomy

Background & Unmet Need

• A decompressive craniectomy is a surgery in which a bone flap of the skull is removed to relieve intracranial pressure on the brain
• Every year, >100 K people in the United States have decompressive craniectomies, primarily as a result of stroke, infection, or traumatic brain injury
• The procedure to replace the bone flap (cranioplasty) may not occur for several months, leaving the brain unprotected and vulnerable to outside forces
• To protect the brain from further injury, patients usually wear a helmet, which is heavy and uncomfortable
• Unmet Need: A low-cost skull protective device that provides personalized protection, comfort, and cosmetic appeal is needed

Technology Overview

• The Technology: An external skull prosthesis that offers localized protection of the brain at the surgical site after cranial bone removal
• The prosthesis is designed to curve around the skull, providing a cranial protection at a specific surgical site
• This skull protective prosthesis has a precise joint system for size adjustment, and incorporates holes for breathability and future attachment capability
• PoC Data: A prototype of the device was successfully produced using 3D printing and incorporated into multiple cranial attachment systems, including a head wrap, wig, and skull cap
• Compared to bulky protective devices such as helmets, this technology offers targeted protection that reduces weight, improves patient comfort, and is more aesthetically pleasing

Technology Applications

• External skull prosthesis to provide brain protection in individuals following craniectomy
• Prosthesis for other conditions in which a portion of the skull is weakened or missing

Technology Advantages

• Simple to customize to meet the needs of each patient
• Aesthetically appealing with various attachment options
• Excellent breathability and comfort
