Claim 12:
13. An apparatus for providing radiation treatment to an anatomical lumen, comprising:
(a) a flexible elongated member having a length and a girth, said flexible elongated member extending between a proximal input and a distal tip, said flexible elongated member comprising a proximal portion adjacent said proximal input and a distal portion adjacent said distal tip, said flexible elongated member defining:
(i) at least one proximal balloon inflation lumen having a closed distal end;
(ii) at least one distal balloon inflation lumen having a closed 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 flexible elongated member, said at least 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 flexible elongated member, one of said at least one distal balloons being positioned between one of said at least one proximal balloons and said distal tip of said flexible 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 flexible elongated member, one of said at least one distal balloon lumens opening into one of said said at least one distal balloons; and
(d) a separate coupling member adapted to be coupled to an inflation fluid source, coupling member being separately formed from said flexible elongated member,
wherein said coupling member defines at least one proximal lumen channel feature and at least one distal lumen channel feature for coupling the output of said inflation fluid source to said at least one proximal balloon lumens and said at least one distal balloon lumens, wherein said coupling member comprises:
(i) a hub insert defining an inner portion of said at least one proximal and said at least one distal lumen channel features;
(ii) a hub outer body defining the outer portion of said at least one proximal lumen channel feature and said at least one distal lumen channel feature, said hub insert being positioned within said hub outer body; and
wherein said hub insert and said hub outer body together define a hub member having an output, and said flexible elongated member is mounted in the output of said hub member.
