Claim 1:
2. 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 an open distal end;
(ii) at least one distal balloon inflation lumen having 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 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 portion of said flexible 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 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 at least one distal balloons;
(d) a coupling member adapted to be coupled to an inflation fluid source,
wherein said coupling member comprises:
(i) a hub insert; and
(ii) a hub outer body, said hub insert being positioned within said hub outer body;

wherein said at least one proximal balloon lumen extends from said proximal input of said flexible elongated member to said distal tip of said flexible elongated member; and
said at least one distal balloon lumen extends from said proximal input of said flexible elongated member to said distal tip of said flexible elongated member; and
(e) a tip member, separately formed from said flexible elongated member, said tip member being adapted to be secured to the distal end of said flexible 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.
