摘要:
An implantable medical device including an implantable elongate component and at least one elongate drug-delivery element. The elongate drug-delivery element releasably carries at least one drug and is configured to be mounted to the elongate component such that the longitudinal axis of the drug-delivery element is substantially parallel with a longitudinal axis of the elongate component.
摘要:
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.
摘要:
A method of forming a non-linear path of at least a portion of at least one electrically conducting wire extending between a first location and a second location. The method includes the steps of forming a wire path template defining a non-linear path, winding said wire through said template such that said wire adopts said non-linear path, connecting the wire to a feedthrough member, wherein the feedthrough member is configured to provide an electrical connection through a wall of an implantable component implantable in a recipient along with the wire, and removing the wire from the template.
摘要:
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.

An indent printing apparatus that is capable of indent printing on both sides of a document. A desktop card printer that uses the indent printing apparatus, a method of personalizing a document in the printer, and a ribbon cartridge used with the indent printing apparatus are also disclosed. The indent printing apparatus has first and second indenting mechanisms and uses first and second indent printing ribbon cartridges to enable indent printing on both side surfaces of the document.

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.
摘要:
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.

摘要:
There is disclosed a method of forming a patterned conductive element for an implantable medical device, the method comprising the steps of: depositing a supplementary material on a sheet of conductive, parent material to form a sheet of composite material; applying a carrier material over the supplementary material of the composite sheet to form a sheet of semi-finished material; removing portions from at least the conductive parent material of the sheet of semi-finished material in accordance with a desired pattern corresponding to a patterned conductive element to be formed; and releasing at least the carrier material from the sheet of semi-finished material.
