  • Method and apparatus for robotically assisted cochlear implant surgery
    Patent number: 9020613
    Abstract: A novel sensing system and methods for preventing damage to the cochlea during cochlear implant surgery are disclosed, using optical sensing to determine the distance of a stylet or the end of the implant itself from the interior wall of the scalar tympani. A variety of feedback methods are proposed to enable the surgeon to perform the procedure safely without damage to the basilar membrane or other delicate anatomic structures. Although a number of embodiments are disclosed, one preferred embodiment comprises a robotically manipulated end-effector.
    Type: Grant

    Date of Patent: April 28, 2015
    Assignee: The Johns Hopkins University
    Inventors: Russell H. Taylor, John Niparko, Iulian Ioan Iordachita, Wade Wei-De Chien
  • Method and apparatus for cochlear implant surgery
    Patent number: 8886330
    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.
