Claim 18:
19. An apparatus for providing radiation treatment to an anatomical lumen, comprising:
(a) an elongated member having a length and a girth, said elongated member extending between a proximal input and a distal tip, said elongated member comprising a proximal portion adjacent said proximal input and a distal portion adjacent said distal tip, said elongated member defining:
(i) at least one proximal balloon lumen having a proximal input and an open distal end;
(ii) at least one distal balloon lumen having a proximal input and an open distal end; and
(iii) a source lumen having a length, said source lumen being configured and dimensioned to enable delivery of a radiation source to a desired position along the length of the source lumen;

(b) at least one proximal balloon mounted on said proximal portion of said elongated member, said at least one one proximal balloon being inflatable to a size which fills a substantial portion of said anatomical lumen, said at least one proximal balloon being inflatable to a girth larger than the girth of said elongated member, one of said at least one proximal balloon lumens opening into one of said at least one proximal balloons;
(c) at least one distal balloon mounted on said distal of said elongated member, said at least one distal balloon being positioned between one of said at least one proximal balloons and said distal tip of said elongated member, said at least one distal balloon being inflatable to a size which fills a substantial portion of said anatomical lumen, said at least one distal balloon being inflatable to a girth larger than the girth of said elongated member, one of said at least one distal balloon lumens opening into one of said at least one distal balloons; and
(d) a coupling member separate from said elongated member adapted to be coupled to an inflation fluid source, said coupling member comprising at least one proximal balloon inflation valve for providing fluid under independently controllable pressure to one of said at least one proximal balloon lumens at said proximal input of said elongated member, and at least one distal balloon inflation valve for providing fluid under independently controllable pressure to one of said at least one distal balloon lumen at said proximal input of said elongated member, whereby said at least one proximal balloon and said at least one distal balloon may be independently inflated;
wherein said at least one proximal balloon lumen extends from said proximal input of said elongated member to said distal tip of said elongated member; and, said at least one distal balloon lumen extends from said proximal input of said elongated member to said distal tip of said elongated member
wherein said coupling member is coupled to said proximal input of said elongated member,, said coupling member defining coupling member passages, said coupling member passages being coupled in sealing relationship to a respective one of said proximal inputs of said proximal balloon lumen and said distal balloon lumen; and, (e) a tip member, separately formed from said elongated member, said tip member being adapted to be secured to the distal end of said elongated member, said tip member being positioned and configured to close said open distal end of said proximal balloon inflation lumen and the open distal end of said distal balloon inflation lumen.
