Abstract
A system for cochlear implant surgery includes a reference device having at least a portion adapted to be arranged at a fixed position relative to a cochlea of a patient to provide a reference position, an image acquisition and processing system adapted to acquire an image of at least a portion of the cochlea relative to the reference position and to provide an implant plan based at least partially on the acquired image, and an implant system adapted for implanting a cochlear lead array using the reference position and the implant plan.
Claims37
A system for cochlear implant surgery, comprising:
- a reference device having at least a portion adapted to be arranged at a fixed position relative to a cochlea of a patient to provide a reference position;
- an image acquisition and processing system adapted to acquire an image of at least a portion of said cochlea relative to said reference position and to provide an implant plan based at least partially on the acquired image;
- and
- an implant system adapted for implanting a cochlear lead array using said reference position and said implant plan.
A reference device comprising a spring structure such that said reference device has a size and shape to be insertable into and removable from an opening made during at least one of a cochleostomy or mastoidectomy surgical procedure while said spring structure is in a compressed configuration and said reference device is fixed in position while said spring structure is in a restored configuration.
A method of surgically implanting a prosthetic device in a patient's cochlea, comprising:
- providing a fiducial reference at a spatially fixed position relative to said patient's cochlea;
- acquiring an image of at least a portion of said patient's cochlea relative to said fiducial reference;
- processing said image to determine a surgical implant plan;
- and
- providing results of said surgical implant plan for a surgeon to implant at least a portion of said prosthetic device using sad implant plan and said fiducial reference.
