| 20100057180 | IMPLANTABLE CARRIER MEMBER HAVING A NON-COMMUNICATIVE LUMEN - A non-communicative lumen for electrode assemblies of medical implants, in particular prosthetic hearing implants, is provided by the present invention. The non-communicative lumen prevents the lumen within the cochlea from being able to transport fluids, cells, bacteria, tissue, etc., with the lumen outside the cochlea, and vis versa through the incision or cochleostomy. The lumen may have a cavity or slit that receives a stylet during insertion of the electrode assembly. | 03-04-2010 |
| 20100106232 | HEARING PROSTHESIS ELECTRODE ARRAY WITH RESILIENTLY FLEXIBLE TIP MEMBER - A tip member for inserting into the cochlea, a device comprising: an elongate member including at least one electrode mounted thereon; and a tip member extending distally from a distal end of the elongate member, the tip member comprising a tapered portion tapering distally and a blunt end portion at a distal end of the tapered portion, wherein the tip member is resiliently flexible, and a method for making such a device. | 04-29-2010 |
| 20100305676 | COCHLEAR IMPLANT ELECTRODE ASSEMBLY - Disclosed is a lead for a cochlear implant modified so as to provide increased robustness to the lead. In one aspect, the lead has a helix region having an increased length such that it extends into a mastoid cavity of a patient when in situ. Also disclosed is a cochlear implant having a lead as described herein. In another aspect, the lead has an increased lead angle between the helix region and the transition region. | 12-02-2010 |
| 20110034969 | ELECTRODE ARRAY FOR A COCHLEAR IMPLANT - Disclosed is an electrode having a conducting wire and an electrode contact for a medical implant, the electrode being at least partially formed by Carbon Nanotubes (CNTs). Also disclosed are medical implants using the electrodes disclosed, as well as methods of manufacture of the electrode and medical implants. In one particular example, the electrode is formed with a CNT strand forming the conducting wire and a CNT sheet forming the electrode contact. | 02-10-2011 |

| 20110022146 | MANUFACTURING AN ELECTRODE ARRAY FOR A TUMULATINGL MEDICAL DEVICE - A method of forming an electrode array is disclosed, the method comprising: forming an elongate comb structure comprising a plurality of longitudinally-spaced electrode contacts extending from and supported by a spine; electrically connecting each of a plurality of electrically conductive pathways to a respective one of the plurality of electrode contacts; placing the conductive pathways adjacent the contacts; placing silicone over the conductive pathways and contacts; curing the silicone so as to substantially retain the longitudinal spacing between neighboring contacts; and severing the spine from the plurality of electrode contacts. | 01-27-2011 |
| 20110144733 | Electrode for a Cochlear Implant - An electrode for a cochlear implant for implantation in a cochlea of a patient, the electrode having a first side that is curved in a lateral dimension so as to substantially conform to a side wall of a scala upon implantation of the electrode into a cochlea and a second side that is shaped so as to preserve a natural acoustic pathway within the scala upon implantation of the electrode into the cochlea. In one example, opposing ends of the electrode taper off in cross section. In another example, the fluid contact side is concave. In a further example, the electrode is one of crescent-shaped, oval shaped, and semi-circular in cross section. By using such an electrode, a more natural fluid-flow in the cochlea can be maintained after implantation relative to an original fluid-flow prior to implantation. | 06-16-2011 |
| 20110152991 | STRAIN RELIEF IN AN IMPLANTABLE ELECTRODE ASSEMBLY - An implantable electrode assembly. The electrode assembly comprises an elongate carrier member, at least one electrode contact disposed in the carrier member, and at least one elongate conductive pathway disposed in the carrier member having a distal end attached to the at least one electrode contact and having a substantially planar strain relief formed therein that is located only in the distal region of the at least one pathway. | 06-23-2011 |
| 20110201997 | COCHLEAR IMPLANT ELECTRODE LEAD HAVING A CROSS-SECTION WITH VARIABLE HEIGHT - An electrode lead for a cochlear implant, the electrode lead having a lateral side and a medial side supporting an electrode array, wherein a height of a cross section of the electrode lead is greater in the lateral side than a height of the cross section in the medial side. | 08-18-2011 |
