20110056725 | INSULATED CONDUCTIVE ELEMENT HAVING A SUBSTANTIALLY CONTINUOUS BARRIER LAYER FORMED VIA RELATIVE MOTION DURING DEPOSITION - Coating an elongate, uncoated conductive element with a substantially continuous barrier layer. An uncoated conductive element is around a frame comprising spaced supports. During deposition, the relative position of the conductive element to the frame is adjusted so that all sections of the conductive element are physically separated from the supports for a time that is sufficient to form a desired coating of barrier material on all sections of the conductive element. | 03-10-2011 |
20110056726 | INSULATED CONDUCTIVE ELEMENT HAVING A SUBSTANTIALLY CONTINUOUS BARRIER LAYER FORMED THROUGH MULTIPLE COATINGS - Coating an elongate, uncoated conductive element with a substantially continuous barrier layer. The substantially continuous barrier layer is formed through relative movement of the conductive element to a frame between sequential coatings of a barrier material. | 03-10-2011 |
20110056729 | INSULATED CONDUCTIVE ELEMENT HAVING A SUBSTANTIALLY CONTINUOUS BARRIER LAYER FORMED THROUGH CONTINUOUS VAPOR DEPOSITION - A continuous vapor deposition system for coating an elongate, uncoated conductive element with a substantially continuous barrier layer. The system comprises an internal deposition chamber configured to have a section of the conductive element extend there through; a vapor supply system connected to the internal deposition chamber configured to provide a barrier material to the internal deposition chamber, wherein the barrier material is deposited on the section of the conductive within the internal deposition chamber to form a substantially continuous barrier layer; and a guide system positioned adjacent to the first deposition chamber configured to maintain tension in the section of the conductive element in the internal deposition chamber to control movement of the conductive element through the internal deposition chamber. | 03-10-2011 |
20110060396 | INSULATED CONDUCTIVE ELEMENT HAVING SUBSTANTIALLY CONTINUOUSLY COATED SECTIONS SEPARATED BY UNCOATED GAPS - Coating an elongate, uncoated conductive element with a barrier layer to form an insulated conductive element. The insulated conductive element comprises substantially continuously coated elongate sections separated by uncoated gaps which are substantially small relative to the lengths of the coated sections. | 03-10-2011 |

20130190839 | DRUG DELIVERY USING A SACRIFICIAL HOST - An implantable drug-doped component, e.g., a cochlear implant, includes host material, a host-embedded drug and a sacrificial material integrated with the host. Upon exposure of the sacrificial material to a solvent, e.g., perilymph fluid, voids in the host are created which facilitate release of the drug. The host can be, e.g., polysiloxane or silicone rubber. The sacrificial material, e.g., can be a glucose monomer, sugar, cyclodextrin, a salt, a bioresorbable material, hyaluronic acid, polyurethane, polyester, polyamide, polyvinyl alcohol, polyacrylic acid, etc. Alternatively, the sacrificial material can be the host, and can facilitate release of the drug through changing a property of the sacrificial material, e.g., by exposing the component to an ethanol wash. For a cochlear implant, e.g., the drug doped material can be applied to a non-stimulating surface of the electrode array. | 07-25-2013 |
20140180195 | Drug-Delivery Accessory for an Implantable Medical Device - An implantable drug-delivery sleeve for an elongate component of an implantable medical device. The sleeve includes a tubular substrate having a lumen configured to receive the elongate component so as to allow relative displacement of the substrate and the elongate component, wherein the substrate is shaped so as to be retained stationary at a desired position along the elongate component, and a drug releasably carried by the substrate. | 06-26-2014 |
20140188033 | DRUG DELIVERY USING A SACRIFICIAL HOST - Implantable drug-doped component, e.g., a cochlear implant, including host material, a host-embedded drug, a sacrificial material integrated with the host. Sacrificial material facilitates release of drug from the component. Sacrificial material facilitates release through creation of voids in the host upon dissolution of sacrificial material upon contact with a solvent, e.g., perilymph fluid upon implant. Host can be polysiloxane, or silicone rubber. Drug can be anti-inflammatory, growth factor, antibody, anti-oxidant, antibiotic, corticosteroid. Sacrificial material can be: glucose monomer, sugar, cyclodextrin, dissolvable or resorbable at implant site, a salt, bioresorbable material, hyaluronic acid, polyurethane, polyester, polyamide, polyvinyl alcohol, polyacrylic acid. Sacrificial material can be the host, and can facilitate release of drug through changing a property of sacrificial material, e.g., by exposing component to ethanol wash. For a cochlear implant, drug doped material can be applied to a non-stimulating surface of the electrode array, and can be a physical feature of stimulating medical device, e.g., soft tip, ridge, spine. For a cochlear implant the drug-doped material can excluded from the basal side of the most basal electrode contact. | 07-03-2014 |
