Abstract
Devices, methods and systems for transmitting signals through a device located in a blood vessel of an animal, for stimulating and/or sensing activity of media proximal to the device, wherein the media includes tissue and/or fluid.
Claims19
A medical device for use within a tubular body having a lumen and for use with an implantable control unit, the medical device comprising:
- a frame structure forming a plurality of struts, where the frame structure is moveable between a reduced profile and an expanded profile in which a diameter of the frame structure increases;
- where at least one of the plurality of struts forming the frame structure comprises a conductive material and a non-conductive material, the non-conductive material surrounding the conductive material;
- and
- at least one electrode formed by an opening in the non-conductive material that exposes the conductive material;
- a stent shaft coupled to the frame configured to assist positioning of the frame structure within the lumen;
- a lead extending within the stent shaft and away from the frame structure, where the conductive material extends along the strut to electrically couple with the lead, and where a proximal end of the lead is electrically coupleable to the implantable control unit.

A medical device for use within a tubular body having a lumen, the medical device comprising:
- a frame structure forming a plurality of struts, where the frame structure is moveable between a reduced profile and an expanded profile in which a diameter of the frame structure increases;
- the plurality of struts being formed by a support material, a non-conductive material, and a conductive path, the conductive path being partially embedded within the non-conductive material;
- and
- the conductive path being exposed to the tubular body at an opening in the non-conductive material, forming at least one electrode.
