Patents by Inventor Frank Risi

Frank Risi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240148463
    Abstract: 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.

  • Publication number: 20230285747
    Abstract: 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.

  • Patent number: 11484704
    Abstract: 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.
