Abstract
An elongate stimulation assembly of an implantable stimulation device, including a first portion including a plurality of electrodes, lead wires extending from the first portion in electrical communication with the plurality of electrodes, the lead wires being located in an elongate lead body and a cage component extending in an elongate manner at least partially along with the lead wires, wherein the lead wires extend within the cage component.
Claims39
An elongate stimulation assembly of an implantable stimulation device, comprising:
- an intra-cavity portion including a plurality of electrodes;
- and
- an extra-cavity portion extending from the intra-cavity portion, wherein
- the extra-cavity portion includes a plurality of electrical lead wires in electrical communication with the plurality of electrodes and a malleable component extending in an elongate manner such that at least a portion of the malleable component is located further away from or the same distance from a longitudinal axis of the extra-cavity portion than a portion of least one of the electrical leads of the plurality of electrical leads.
An elongate stimulation assembly of an implantable stimulation device, comprising:
- a first portion including a plurality of electrodes;
- lead wires extending from the first portion in electrical communication with the plurality of electrodes, the lead wires being located in an elongate lead body;
- and
- a cage component extending in an elongate manner at least partially along with the lead wires, wherein the lead wires extend within the cage component.
A device, comprising:
- a stimulating assembly of an implantable stimulating device, including a lead assembly made at least partially of a structure having portions that are more susceptible to plastic deformation than other portions of the structure, wherein
- the device is configured to resist movement of at least a portion of the lead assembly, the movement of the lead assembly being due to the plastic deformation.
A method, comprising:
- obtaining an implantable cage apparatus;
- moulding silicone so that the cage apparatus is encapsulated in an overmoulded silicone tube, thus resulting in a silicone tube-cage assembly;
- and
- inserting the silicone tube-cage assembly over a plurality of lead wires of a cochlear implant electrode array and/or inserting the plurality of lead wires into the silicone tube-cage assembly.
