| 20090292237 | Modular Drug Delivery System for Minimizing Trauma During and After Insertion of a Cochlear Lead - A system for delivering therapeutic agents to biological tissue includes a surgically implantable lead configured to be inserted into the biological tissue, the surgically implantable lead including a preformed cavity; and a modular capsule containing a therapeutic agent which includes dexamethasone base; the modular capsule being secured within the preformed cavity; the modular capsule releasing the therapeutic agent into the biological tissue. A method of delivering therapeutic agents to biological tissue includes obtaining a surgically implantable lead with a preformed cavity; obtaining a modular capsule containing a therapeutic agent comprising dexamethasone base and securing it within the preformed cavity; and inserting the surgically implantable lead into the biological tissue. | 11-26-2009 |
| 20100070000 | METHODS AND SYSTEMS OF CONVEYING FINE STRUCTURE INFORMATION TO A COCHLEAR IMPLANT PATIENT - An exemplary method of conveying fine structure information to a cochlear implant patient includes dividing an audio signal into a plurality of analysis channels, generating electrical stimulation in accordance with the information contained within each of the analysis channels, applying the electrical stimulation to at least one stimulation site within a patient via a plurality of stimulation channels, and at least partially isolating one of the stimulation channels from a rest of the stimulation channels, wherein fine structure information is conveyed to the patient via the isolated stimulation channel. Corresponding methods and systems are also disclosed. | 03-18-2010 |
| 20100114288 | COCHLEAR ELECTRODE INSERTION - A system for mechanically assisted insertion of an electrode includes: an insertion tool configured to insert the electrode into biological tissues; and a controller configured to control the insertion tool, in which the controller is further configured to select operating parameters comprising a maximum allowable force profile from a library of operating parameters, in which the maximum allowable force profile is generated from data recorded during a number of previous successful operations. Also, a method for insertion of a cochlear lead, includes: selecting operating parameters comprising a maximum allowable force profile from a library of operating parameters; inserting the cochlear lead while sensing real time force and position; and continuing the insertion while the real time force is below the maximum allowable force profile, in which the maximum allowable force profile is generated from data recorded during a number of previous successful operations. | 05-06-2010 |
| 20100318158 | Optimizing Pitch and Other Speech Stimuli Allocation in a Cochlear Implant - Errors in pitch (frequency) allocation within a cochlear implant are corrected in order to provide a significant and profound improvement in the quality of sound perceived by the cochlear implant user. In one embodiment, the user is stimulated with a reference signal, e.g., the tone “A” (440 Hz) and then the user is stimulated with a probe signal, separated from the reference signal by an octave, e.g., high “A” (880 Hz). The user adjusts the location where the probe signal is applied, using current steering, until the pitch of the probe signal, as perceived by the user, matches the pitch of the reference signal, as perceived by the user. In this manner, the user maps frequencies to stimulation locations in order to tune his or her implant system to his or her unique cochlea. | 12-16-2010 |
