Abstract
An apparatus including a therapeutic substance delivery device configured for attachment to a first tissue area internal of a recipient, the delivery device configured to enable movement of a therapeutic substance outlet of the delivery device proximate a second tissue area away from the first tissue area after attachment to the first tissue area to deliver the therapeutic substance from the outlet while implanted in the recipient.
Claims35
An apparatus, comprising:
- a therapeutic substance delivery device configured for attachment to a first tissue area internal of a recipient, the delivery device configured to enable movement of a therapeutic substance outlet, via movement of a component of which the outlet is a part, of the delivery device proximate a second tissue area away from the first tissue area after attachment to the first tissue area to deliver a therapeutic substance from the outlet while implanted in the recipient, wherein
- the component is stowed, prior to the movement of the component, over a distance less than 30 mm.
An apparatus, comprising:
- a first structure configured to be attached to tissue internal of a recipient;
- and
- a second structure configured to be supported by the first structure in an initial state during a first temporal period, and configured to be deployed from the first structure in a deployed state during a second temporal period after the first temporal period, wherein the apparatus is a therapeutic substance delivery device configured to deliver therapeutic substance from the second structure to a location remote from the first structure during and/or after deployment of the second structure,
- the second structure is at least one of in or controllably placeable in fluid communication with the first structure so that therapeutic substance can travel from the first structure to the second structure, and at least one of:
- the second structure includes a plurality of therapeutic substance outlets, wherein a diameter of a first of the plurality of outlets is larger than a diameter of a second of the plurality of outlets, wherein the first of the plurality of outlets is located more distally than the second of the plurality of outlets as a result of deployment from the first structure in the deployed state;
- or
- the second structure includes a plurality of diffusion zones spaced apart from one another.

An apparatus, comprising:
- a therapeutic substance delivery device configured for attachment to a first tissue area internal of a recipient, the delivery device configured to enable movement of a therapeutic substance outlet, via movement of a component of which the outlet is a part, of the delivery device proximate a second tissue area away from the first tissue area after attachment to the first tissue area to deliver a therapeutic substance from the outlet while implanted in the recipient, wherein
- the component is stowed, prior to the movement of the component, in a bunched up and/or rolled up state.
