Implanted Ceramic Case With Enhanced Ceramic Case Strength

View page
US Patent:
6411854, Jun 25, 2002
Filed:
Jul 14, 1999
Appl. No.:
09/353237
Inventors:
George Tziviskos - Woodland Hills CA
Tom J. Law - Tempe AZ
Alfred E. Mann - Beverly Hills CA
Assignee:
Advanced Bionics Corporation - Sylmar CA
International Classification:
A61N 1375
US Classification:
607 57, 607 2
Abstract:
An implantable medical device is made from an electronic subassembly hermetically sealed in a ceramic case filled with a potting material. Use of the potting material enhances the capacity of the device to withstand mechanical shock without failure. The device includes a hollow ceramic or other case having an open end to which a metal ring is hermetically bonded. The inside surface of the ceramic case is treated (cleansed and activated) to assure the potting material adheres to it. The potting material, while in a non-cured fluid or quasi-fluid state, is inserted inside of the ceramic case. The electronic circuitry is next inserted into the open end of the ceramic case while the potting material is still in a non-cured, soft or fluid state. The electronic circuitry displaces some of the potting material and the potting material fills the voids between the electronic circuitry and the ceramic case. The potting material is then slowly cured, and once cured, supports the walls of the ceramic case and protects the electronic circuitry embedded therein.

Water-Resistant, Wideband Microphone Subassembly

View page
US Patent:
6505076, Jan 7, 2003
Filed:
Dec 8, 2000
Appl. No.:
09/733736
Inventors:
George Tziviskos - Encino CA
W. Gary Sokolich - Newport Beach CA
Scott Crawford - Castaic CA
Lee F. Hartley - Castaic CA
Assignee:
Advanced Bionics Corporation - Sylmar CA
International Classification:
H04R 2500
US Classification:
607 57, 607 55, 381328, 381330
Abstract:
A moisture-resistant, wideband microphone subassembly for a Behind-The-Ear (BTE) hearing device, provides a barrier to perspiration and rain, while maintaining a good frequency response. The microphone subassembly is contained in the case of the BTE hearing device and comprises a microphone, a boot, and a moisture-resistant membrane. The boot structurally supports the microphone, provides a moisture seal around the microphone case, and provides the microphone with isolation from vibrations in the case of the BTE hearing device. The membrane resists the passage of moisture, while providing an acoustic window permitting sound waves to reach the microphone. In one embodiment high compliance washers sandwich the membrane to improve frequency response. A preferred embodiment provides a substantially flat acoustic frequency response to beyond 10 KHz.

Connector System For Bte Hearing Devices

View page
US Patent:
6748094, Jun 8, 2004
Filed:
Feb 16, 2001
Appl. No.:
09/785629
Inventors:
George Tziviskos - Encino CA
Tom J. Law - Chandler AZ
Assignee:
Advanced Bionics Corporation - Sylmar CA
International Classification:
H04R 2500
US Classification:
381330, 381322, 381324
Abstract:
A connector system for Behind-The-Ear (BTE) hearing devices provides a means to detachably connect a plurality of earhooks, which earhooks include special earhooks providing auxiliary functions. The connector system includes a coaxial connector mounted on the BTE device, which coaxial connector provides both an earhook mounting fixture, and an electrical connector for auxiliary functions. The auxiliary functions include a telecoil, an auxiliary microphone positioned proximal to an ear canal, an FM receiver, and an input jack for miscellaneous devices. The earhook mounting fixture also accepts standard off-the-shelf earhooks. A friction fit is provided between the earhook and the BTE device so that the angular position of the earhook may be adjusted for a comfortable fit.

Filed:
Jun 7, 2004
Appl. No.:
10/863563
Inventors:

Assignee:
Advanced Bionics Corporation - Valencia CA
International Classification:

Anodic Protection Of Electrical Contacts

View page
US Patent:
7097746, Aug 29, 2006
Filed:
Nov 20, 2002
Appl. No.:
10/301026
Inventors:
George Tziviskos - Encino CA, US
C. Geoffrey E Fernald - La Canada CA, US
Assignee:
Advanced Bionics Corporation - Valencia CA
International Classification:
C23F 13/00
US Classification:
20419623, 20419624, 20419625, 205730, 205731, 205732, 205733, 381330, 381322, 381323, 381324
Abstract:
An anode protection device and method are provided. The method includes placing a sacrificial anode in proximity to the positive and negative contacts to shield or distort the field therebetween which provides preferential corrosion of the sacrificial anode, instead of the anode. The protection device is a sacrificial anode having various forms and placed in different configurations. In one form the sacrificial anode is a plate. In another form the sacrificial anode is a ring placed around either the positive contact or negative contact to provide a shield between the negative and positive contacts. In a further device embodiment, the sacrificial anodic plate can be welded to the aluminum case of a rechargeable battery of a behind-the-ear (BTE) hearing device.

Hermetic Seal

View page
US Patent:
7837085, Nov 23, 2010
Filed:
Apr 7, 2004
Appl. No.:
10/819610
Inventors:
George Tziviskos - Encino CA, US
Assignee:
Boston Scientific Neuromodulation Corporation - Valencia CA
International Classification:
B23K 31/02
H01G 7/00
H01G 4/35
US Classification:
2281221, 2281246, 29 2542, 361302, 429181
Abstract:
A seal design provides positive compression to produce a hermetic seal around a feedthrough pin in a hermetically sealed device, including an implantable medical device. One embodiment of the seal design uses a plurality of “micro-flanges” placed along the length of a feedthrough pin, which micro-flanges grabs and compresses the insulator material to form a hermetic seal. Because the seal design produces positive compression of the insulator, the seal is relatively insensitive to changes in temperature and to differences in thermal expansion coefficients (“TCEs”) between the metal feedthrough and the insulator. It is therefore possible to use a wider variety of materials for the insulator and the feedthrough with the described sealing design, while achieving a superior hermetic seal.

Atraumatic High-Retention Headpiece

View page
US Patent:
8027735, Sep 27, 2011
Filed:
Mar 31, 2009
Appl. No.:
12/415977
Inventors:
George Tziviskos - Encino CA, US
Michael D. Brownen - Keller TX, US
William G. Orinski - Stevenson Ranch CA, US
Assignee:
Advanced Bionics, LLC - Valencia CA
International Classification:
A61N 1/00
US Classification:
607 57
Abstract:
A headpiece for a cochlear implant system includes a transcutaneous transmission coil that transfers power and/or data to an implantable device implanted under a user's skin. The headpiece includes a magnet for holding the transmission coil in close proximity to the receiver coil in the implanted device, which also contains a magnet, and provides the desired alignment between the coils so that inductive coupling may efficiently occur. The headpiece has a bottom surface for skin contact that includes a plurality of flexible bumps configured to distribute pressure over a large surface area while allowing blood flow throughout the area. This also provides friction contact with the skin to help secure the headpiece, reducing movement due to lateral loading, while reducing skin irritation and erosion.
