MEDICAL DEVICES AND METHODS OF MAKING THE SAME
Medical devices, such as stents, and methods of the devices are described. In some embodiments, the invention features a method of making a medical device including providing a body having an electrically insulating first member defining an elongated lumen, and an electrically conducting second member on a first surface of the first member, removing a portion of the second member, and forming the body into the medical device, e.g., a stent.

17 . A stent, comprising:
a tubular body defining a lumen, the body comprising
an electrically insulating first member, and
an electrically conducting second member on a first surface of the first member, the second member defining a lumen and having multiple thicknesses.
18 . The stent of claim 17 , wherein the second member defines a non-centric lumen.
19 . The stent of claim 17 , wherein the second member defines a circular lumen.
20 . The stent of claim 17 , wherein the second member defines a non-circular lumen.
21 . The stent of claim 17 , wherein the first member comprises a polymer or a ceramic.
22 . The stent of claim 17 , wherein the second member comprises a non-ferrous material.
23 . The stent of claim 17 , further comprising an electrically conducting third member on a second surface of the first member, the third member defining a lumen.
24 . The stent of claim 23 , wherein the lumens of the second and third members are displaced relative to each other about a circumference of the body.
25 . The stent of claim 17 , wherein the third member has multiple thicknesses.
26 . The stent of claim 23 , further comprising a strut consisting of a portion of the insulating first member and a portion of the conducting third member.
27 . The stent of claim 17 , further comprising a strut consisting of a portion of the insulating first member and a portion of the conducting second member.

a body defining a lumen, the body comprising
an electrically insulating first member, and
an electrically conducting second member on a first surface of the first member, the second member having multiple thicknesses.
40 . A stent, comprising:
a tubular body including in at least a circumferential portion thereof a circumferentially continuous, non-conducting material, and a circumferentially non-continuous, conducting material.
41 . The stent of claim 40 , wherein the thickness of the non-conducting material is substantially circumferentially constant.
42 . The stent of claim 40 , comprising first and second non-continuous, conducting material on the inner and outer surfaces of the non-conducting material.
43 . The stent of claim 40 , wherein the conducting material has variable thickness.
44 . The stent of claim 40 , further comprising a strut consisting of a portion of the non-conducting material and a portion of the conducting material.
45 . The stent of claim 40 , wherein the conducting material defines a non-centric lumen.
