An apparatus including an actuator and an electrode array support, wherein the apparatus is configured to insert an electrode array into a cochlea via controlled actuation of the actuator, wherein the controlled actuation is at least partially based on data that is at least partially based on electrical characteristics associated with the recipient.

Advanced electrode array insertion

A vestibular stimulation array is disclosed having one or more separate electrode arrays each operatively adapted for implantation in a semicircular canal of the vestibular system, wherein each separate electrode array is dimensioned and constructed so that residual vestibular function is preserved. In particular, the electrode arrays are dimensioned such that the membranous labyrinth is not substantially compressed. Furthermore, the electrode array has a stop portion to limit insertion of the electrode array into the semi-circular canal and is still enough to avoid damage to the anatomical structures.

Vestibular stimulation device

An insertion tool having an insertion guide tube that maintains a perimodiolar or other pre-curved electrode assembly in a substantially straight configuration while preventing the electrode assembly from twisting in response to stresses induced by the bias force which urges the assembly to return to its pre-curved configuration. This generally ensures that when the electrode assembly is deployed from the distal end of the insertion guide tube, the electrode assembly and insertion guide tube have a known relative orientation.

Cochlear implant electrode assembly insertion tool

Disclosed herein are electrode assemblies configured for use with a medical device, such as an implantable medical device. In one aspect, the disclosed electrode assembly includes at least a first electrode and a second electrode, each of which is configured to deliver electrical stimuli to a body part of a recipient. The electrode assembly also includes a first wire that is attached at one end to the first electrode and comprises a conductor that has a first diameter, and a second wire that is attached to the second electrode and comprises a conductor that has a second diameter, with the first diameter being greater than the second diameter. Additionally, each of the first wire and the second wire pass through a proximal end of the assembly is configured to connect the one of the electrodes to a stimulation unit of a medical device.

Implanted medical devices having electrode assemblies

A magnetic alignment system that can form part of a cochlear implant system. The magnetic alignment system prevents substantial movement of a magnet of an implanted component during an MRI procedure or allows for easy removal of the magnet to facilitate the MRI procedure.

Implant magnet system

Systems and methods are disclosed for insertion of implantable medical devices, and more particularly to insertion of implantable devices with a vibrating insertion tool. More specifically, a vibrating insertion tool is described, the insertion tool comprising an insertion tool controllable by a user to support and guide movement of an object, the insertion tool comprising an elongate arm having a proximal end region and a distal end region, the distal end region having a receiving region, a user-controllable vibration source for generating vibrations in accordance with a selected vibration profile, and an elongate rigid spine, connected to the vibration source and the receiving region, configured to deliver the vibrations to the receiving region.
