Publication number: 20120045912Abstract: A connector system for Behind-The-Ear (BTE) hearing devices provides a means to detachably connect a variety of accessories to a sound processor, including batteries, earhooks, telecoils, auxiliary microphones, FM receivers, and input jacks for miscellaneous devices. The present invention provides an efficient and economical sealing connection, eliminating the introduction of sweat, body fluid and other contaminants into the connection area, which otherwise would result in corrosion and eventually disable the connected device. A wiping contact formed by a configuration of cam contacts and a flex circuit with a configuration of corresponding contacts is combined with a rotational engagement mechanism to create a vibration-resistant high contact density connector that is moisture proof when engaged.Type: ApplicationFiled: May 4, 2010Publication date: February 23, 2012Inventors: William A.

Patent number: 8038049Abstract: 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.Type: GrantFiled: October 19, 2010Date of Patent: October 18, 2011Assignee: Boston Scientific Neuromodulation CorporationInventor: George Tziviskos

Patent number: 8027735Abstract: 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.Type: GrantFiled: March 31, 2009Date of Patent: September 27, 2011Assignee: Advanced Bionics, LLCInventors: George Tziviskos, Michael D.

Publication number: 20070113964Abstract: A water-repellent microphone and an improved method for constructing such a water-repellent microphone provides easy assembly and good acoustic performance. In one embodiment, a water-repellent membrane and a washer are pre-assembled. The surface of the washer opposite the membrane is covered by an adhesive, and the adhesive is covered by a removable liner. The method of assembly comprises removing the liner, and pressing the membrane and washer over the sound port of the microphone. The washer provides spacing between the microphone and the membrane and increases the membrane area through which sound passes, thus providing good acoustic performance. In a second embodiment, the washer is provided as a separate element with adhesives and liners on both sides. A first liner is removed and the washer is attached to the membrane or the microphone, and then the second liner is removed and the assembly is completed.Type: ApplicationFiled: November 15, 2002Publication date: May 24, 2007Inventors: Scott Crawford, George Tziviskos

Patent number: 7097746Abstract: 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.Type: GrantFiled: November 20, 2002Date of Patent: August 29, 2006Assignee: Advanced Bionics CorporationInventors: George Tziviskos, C.

Patent number: 6505076Abstract: 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.Type: GrantFiled: December 8, 2000Date of Patent: January 7, 2003Assignee: Advanced Bionics CorporationInventors: George Tziviskos, W.

Patent number: 6411854Abstract: 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.Type: GrantFiled: July 14, 1999Date of Patent: June 25, 2002Assignee: Advanced Bionics CorporationInventors: George Tziviskos, Tom J.

Patent number: 6151526Abstract: An electrode array, made in a straight or curved shape, but made on a flexible carrier so that it can easily bend within a curved body cavity, such as the cochlea. The electrode array having a multiplicity of electrode contacts along a front side of the electrode array and a plurality of flexible ribs located on an opposite rear side. Insertion of the electrode array is performed by inserting the electrode array into the scala tympani (one of the channels of the cochlea) to a desired depth, which desired depth typically involves a rotation of about 360 degrees and causes the flexible ribs to make contact against the outer or lateral wall of the scala tympani, positioning the electrode contacts adjacent the inner wall of the scala tympani.Type: GrantFiled: April 27, 1999Date of Patent: November 21, 2000Assignee: Advanced Bionics CorporationInventor: George Tziviskos
