20110029074 | FIXATION OF OPHTHALMIC IMPLANTS - An ophthalmic device for implantation into a capsular bag of an eye includes an adhesive or adherent that adheres to an eye at certain temperatures or other physical conditions, but has little or no adherence at other temperatures. The ophthalmic device may be an accommodating intraocular lens including an adjustable optic body and a support structure. The support structure includes an outer structure, an intermediate structure, and an adhesive or adherent material disposed over at least a portion of the support structure. The intermediate structure is located between, and connected to, the outer structure and the optic body. The outer structure has an outer face configured for engaging a capsular bag of an eye. The outer face includes an equatorial region, with anterior and posterior regions disposed on opposite sides of the equatorial region. Under a predetermined condition, the posterior region has an adhesion that is greater than an adhesion of the anterior region. | 02-03-2011 |
20120059465 | CAPSULAR MEMBRANE IMPLANTS TO INCREASE ACCOMMODATIVE AMPLITUDE - A support is coupled to the lens capsule to increase accommodation. The support may be adjustable, such that patient refraction and accommodation can be adjusted following surgery. The support may comprise rigidity sufficient to decrease radial movement of the intermediate portion of the lens capsule. The support can be placed on the intermediate portion to decrease radial movement of the intermediate portion of the lens capsule and increase radial stretching of an outer portion of the lens capsule extending between the zonules and the intermediate portion coupled to the support, such that the amount of accommodation of the eye is increased. The support may comprise a biocompatible material capable of stable coupling to the lens capsule following implantation, such that the far vision refraction and accommodation of the eye can be stable following surgery. | 03-08-2012 |
20130156840 | IMPLANTABLE INTRAOCULAR DRUG DELIVERY APPARATUS, SYSTEM AND METHOD - The present invention relates to an apparatus, system and method for, and for providing, intraocular delivery of an active agent. The apparatus, system and method may include an implantable scaffold and an active agent associated with the implantable scaffold. The implantable scaffold and the active agent may be configured to be completely contained within the eye upon implantation. The implantable scaffold may be a mechanical scaffold, or the implantable scaffold may be a chemical scaffold. | 06-20-2013 |
20130304202 | ACCOMMODATING INTRAOCULAR LENS WITH A COMPRESSIBLE INNER STRUCTURE - An accommodating intraocular lens for providing a range of accommodative vision contains an optic and a haptic. The haptic includes a plurality of arms coupled to a compressible inner structure. The compressible inner structure of the haptic is configured to exert a compressive force on the optic in response to an ocular force to provide accommodation. The compressible inner structure can include a plurality of arcuate segments that join to form a ring in the fully compressed state or a sinusoidal ring having a varying radial dimension. | 11-14-2013 |

20090187065 | AUTOMATIC GAIN CONTROL FOR IMPLANTED MICROPHONE - An implantable hearing instrument is provided that reduces the response to unnaturally high vibrations (e.g., due to a patient's own voice), without necessarily or substantially affecting the response to desired signals. The implantable hearing instrument system is operative to selectively alter/lower the gain of signals that have a magnitude above a predetermined threshold. Signals having unnaturally large amplitudes (e.g., due to a patient's own voice) are amplified less than desired signals, so that a patient may experience a more representative sound. | 07-23-2009 |
20090281366 | FLUID CUSHION SUPPORT FOR IMPLANTABLE DEVICE - A system for reducing the vibration sensitivity of an implantable microphone without an equal or greater reduction in sound sensitivity. The system reduces non-ambient vibrations by placing at least one compliant member into the path of transmission for tissue-borne vibration, but not into the path for ambient sound-induced vibration. More particularly, a fluid filled compliant member is disposed between an implanted microphone and an implant wearer's skull. The compliant member and the implanted microphone define a supported system having a natural or resonant frequency. This natural frequency may be set to a value to advantageously isolate the microphone against transmitted vibration. | 11-12-2009 |
20130010988 | Implantable Electret Microphone - An implantable microphone comprises a hermetically-sealed, enclosed volume and an electret member and back plate disposed with a space therebetween and capacitively coupleable to provide an output signal indicative of acoustic signals incident upon at least one of the electret member and back plate. The back plate may be disposed to define a peripheral portion of the enclosed volume, e.g., the back plate may be defined as part of a flexible diaphragm that receives external acoustic signals. Vents may be provided to fluidly interconnect first and second portions of the enclosed volume that are located on first and second sides of the electret member. In another embodiment, the electret member may be flexible and spaced relative to a flexible outer diaphragm. | 01-10-2013 |
20140221729 | AUTOMATIC GAIN CONTROL FOR IMPLANTED MICROPHONE - A method for use in an implantable hearing instrument, including receiving an output signal from an implanted microphone implanted in a person, identifying a first characteristic of said output signal, based on said first characteristic, amplifying said microphone output signal by at least one of a plurality of gain settings to produce an amplified signal, wherein said plurality of gain setting comprise at least two different gain settings, inputting said amplified signal into a signal processor, processing said amplified signal to generate a transducer drive signal; and using said transducer drive signal to drive implanted auditory stimulation device implanted in a person to stimulate an auditory component. | 08-07-2014 |
