The invention provides a system which comprises a medical device that
delivers a combination of therapies. These therapies include the
administration of radiation, biologically active materials, cryotherapy,
and thermotherapy. The present invention is also directed to a method of
treating body lumen surfaces using the system of the invention. A system
is provided for delivering a biologically active material to a surface of
a body lumen being exposed to a radioactive source. In one aspect, the
system comprises an implantable medical device which has two opposing
ends, each having a surface, and a middle portion. The two opposing ends
comprise a biologically active material and the middle portion of the
medical device is substantially free of any biologically active material.
In another aspect, the system delivers a genetic material to a surface of
a body lumen which is exposed to a radioactive source. Another system is
provided for treating a surface of a body lumen in which the system
comprises an implantable medical device which comprises a biologically
active material and a device for applying a therapy source to the parts
of the body lumen surface that are in contact with the opposing ends of
the medical device. The therapy source may be a cryotherapy source or a
thermotherapy source.
