Abstract

A subcutaneous cavity marking device percutaneously implantable in breast tissue during a biopsy procedure. The marking device including at least two implantable bodies, one made from a first material and another made from a second material wherein the first and second materials are different materials and the at least two implantable bodies are adapted to be inserted into a subcutaneous cavity created by removal of tissue. The at least two implantable bodies are detectable via non-invasive techniques as tissue cavity markers and at least one of the at least two detectable bodies is an electronic chip connected to the other of the at least two implantable bodies.

Claims

1-225. -225. (canceled)

226. A subcutaneous cavity marking device percutaneously implantable in breast tissue during a biopsy procedure comprising:

at least two implantable bodies, one made from a first material and another made from a second material wherein the first and second materials are different materials and the at least two implantable bodies are adapted to be inserted into a subcutaneous cavity created by removal of tissue, wherein the at least two implantable bodies are detectable via non-invasive techniques as tissue cavity markers; and

at least one of the at least two detectable bodies is an electronic chip connected to the other of the at least two implantable bodies.

227. The device of claim 226 wherein the electronic chip is disposed within the other of the at least two implantable bodies.

228. The device of claim 226 wherein the other of the at least two implantable bodies is bioabsorbable.

229. The device of claim 227 wherein the other of the at least two implantable bodies is bioabsorbable.

230. The device of claim 228 wherein the electronic chip is disposed within the other of the at least two implantable bodies.

231. The device of claim 226 wherein the other of the at least two implantable bodies is radiopaque.

232. The device of claim 226 wherein the other of the at least two implantable bodies is echogenic.

233. The device of claim 226 wherein the electronic chip is remotely programmable.

234. The device of claim 233 wherein the information can be added after implantation of the electronic chip.

235. The device of claim 226 wherein the information is directly encoded into the electronic chip.

236. The device of claim 226 wherein the information is a code keyed to a corresponding record in a database.

237. The device of claim 226 wherein the information is a pathology report.

238. A subcutaneous cavity marking device percutaneously implantable in breast tissue during a biopsy procedure, the device comprising:

a body detectable by at least one of x-ray and ultrasound; and

an electronic chip, wherein the electronic chip provides information that can be remotely detected.

239. The device of claim 238 wherein the electronic chip is remotely programmable.

240. The device of claim 239 wherein the information can be added after implantation of the electronic chip.

241. The device of claim 238 wherein the information is directly encoded into the electronic chip.

242. The device of claim 238 wherein the information is a code keyed to a corresponding record in a database.

243. The device of claim 238 wherein the information is a pathology report.

244. A method of marking a biopsy site comprising:

disposing an electronic device in a biopsy cavity; and

remotely detecting information from the electronic device.
