Delivery system

Delivery system comprising:

• a first catheter shaft having a proximal end and a distal end, the proximal end having at least first and second openings, the distal end having at least one opening, and a lumen extending from the distal end opening to the at least first and second proximal end openings;
• a second catheter shaft having a proximal end and a distal end, at least a portion being located within the first catheter shaft lumen and extending from the first proximal end opening to the distal end opening, the second catheter shaft having a lumen extending from a distal end opening to at least a side opening in the second catheter shaft located between the distal end and the proximal end, the second catheter shaft further comprising a floating connector located at the proximal end thereof;
• a third catheter shaft having a proximal end and a distal end and being located within the second catheter lumen, extending from the distal end opening to the side opening, exiting through the side opening and extending proximally therefrom and exiting through the second proximal end opening of the first catheter shaft;
• the first catheter shaft, the second catheter shaft, and the third catheter shaft being in a substantially coaxial relationship at the distal end of the first catheter shaft;
• the first catheter shaft and the second catheter shaft being in a substantially coaxial relationship at the first proximal end opening of the first catheter shaft;
• and
• the first catheter shaft and the third catheter shaft being in a substantially coaxial relationship at the second proximal end opening of the first catheter shaft.
