Lumen visualization and identification system for multi-lumen balloon catheter

A multi-lumen balloon catheter for treating breast cancer comprising:

• a plurality of dosing lumens for delivering radioactive treatment to a breast, each dosing lumen having a proximal end and distal end;
• an inflation lumen;
• a connection member coupling the plurality of dosing lumens and fixed at a distal end of the catheter, the connection member having a proximal end and a distal end and defining therein a plurality of openings parallel to each other and extending longitudinally from a proximal end of the connection member towards a distal end of the connection member in which each of the plurality of openings is open only at the proximal end of the connection member, wherein each distal end of each dosing lumen extends into a different one of the plurality of openings of the connection member to retain the respective dosing lumen through the respective opening such that each dosing lumen is coupled to the connection member such that the connection member is fixed in position relative to each dosing lumen, and wherein at least one feature for identifying at least one characteristic of at least one dosing lumen is disposed on the connection member;
• and
• an inflatable member disposed over the distal ends of the plurality of dosing lumens and enveloping at least a portion of the connection member, wherein the inflatable member is coupled in flow communication to the inflation lumen for inflating the inflatable member.
