Abstract:
1. A system for brachytherapy treatment within a body cavity within a patient accessed via a passage through tissue, comprising: an access port device comprising a tubular member comprising a proximal end, a distal end sized for introduction through a passage through tissue into a body cavity, and an expandable member comprising a proximal end attached to the tubular member distal end and a distal end extending distally beyond the tubular member distal end, the tubular member further comprising a working channel extending between the tubular member proximal end and the tubular member distal end and communicating with the interior of the expandable member, the expandable member comprising a substantially enclosed interior in communication with the working channel and an inflation lumen extending between the tubular member proximal end and the tubular member distal end and communicating with the interior of the expandable member for delivering inflation media into the interior for expanding the expandable member; and an expandable brachytherapy applicator comprising an applicator proximal end, an applicator distal end sized for introduction through the working channel of the access port device into the interior of the expandable member, the applicator comprising a plurality of elongate members extending between the applicator proximal and distal ends and comprising pathways for delivering a source of radiation from the applicator proximal end to a distal portion of the applicator, the elongate members movable from a collapsed configuration to an expanded configuration to expand the applicator distal end within the interior of the expandable member.
