Abstract
A catheter assembly includes a main catheter branch having a catheter shaft and a distal end portion. A main balloon and a side balloon are positioned at the distal end portion of the catheter shaft. The main balloon includes a distal waist portion at a distal end thereof and a proximal waist portion at a proximal end thereof. The side balloon includes an inflatable portion, a proximal waist portion, and a distal waist portion, wherein the proximal and distal waist portions define a side inflation lumen. The proximal waist portion of the side balloon and the proximal waist portion of the main balloon are secured to the distal end portion of the catheter shaft at a single bond or connection point to create a proximal balloon joint, wherein the main inflation lumen is in fluid communication with the main balloon and the side inflation lumen.
