Value Proposition:
· Imaging and feedback system for cochlear implantation
· Depth-range sensor
· Adapted for several cochlear implants
· Improves the safety of surgical placement of cochlear implants
Unmet Need
Cochlear implants are surgically implanted devices for individuals that are deaf or hard-of-hearing. Though cochlear implants have high success rates with immediate benefit to patients, the surgical insertion of the cochlear implant is performed with limited visualization. This lack of visibility can result in incorrect insertion that may require additional surgery due to traumatic damage to the basilar membrane within the cochlea. Therefore, there is a strong need for visualizing the delicate anatomic structures of the cochlea to ensure safe and proper placement of cochlear implants by surgeons.
Technology Description
Researchers at Johns Hopkins have developed a real-time imaging system to visualize the three-dimensional structures of the inner ear during cochlear implantation. The technology uses optical coherence tomography (OCT) interfaced with a computer to provide feedback to surgeons on the location of the implant or stylet during implantation surgery. Developed sensors are capable of providing depth measurements in addition to distance between implant and inner ear structures.
