## Abstract

Apparatus and methods are described, including a stent configured to be placed in a lumen. The stent includes a generally cylindrical stent body including a plurality of struts, at least one electrode post protruding from the stent body, and a plurality of antenna posts protruding longitudinally from an end of the stent body. The antenna posts are longitudinally separated from the electrode post. An antenna is disposed annularly on the antenna posts, such that the antenna posts separate the antenna from the end of the stent body, and at least one electrode is coupled to the stent by being placed on the electrode post. Additional embodiments are also described.

## Claims

### Claim 1

Apparatus for use with a tubular structure shaped to define a lumen thereof, the apparatus comprising:
a stent configured to be placed in the lumen, the stent comprising:
a generally cylindrical stent body comprising a plurality of struts;
a plurality of electrode posts protruding from the stent body; and
a plurality of antenna posts protruding longitudinally from an end of the stent body, the antenna posts being longitudinally separated from the electrode posts;
an antenna disposed annularly on the antenna posts, such that the antenna posts separate the antenna from the end of the stent body; and
a plurality of electrodes coupled to the stent by being placed on respective electrode posts of the plurality of electrode posts,
wherein:
(A)
the plurality of electrode posts are disposed around less than 75 percent of a circumference of the stent,
(B)
the stent defines one or more coupling elements, the apparatus further comprising a control capsule that is configured to:
be coupled to the stent via the one or more coupling elements,
receive electrical power from the antenna, and
drive a current through the plurality of electrodes, using the received electrical power, and
(C)
the plurality of electrode posts and the one or more coupling elements are disposed around less than 75 percent of the circumference of the stent, and the one or more coupling elements are rotationally displaced with respect to all of the electrode posts defined by the stent.

### Claim 2 (depends on 1)
