Abstract:
1. A method of manufacturing a catheter assembly, the catheter assembly including a main catheter branch having a catheter shaft, a main balloon, and a side balloon, the catheter shaft having a distal end portion and defining a main inflation lumen, the main balloon having a proximal waist at a proximal end portion thereof and a distal waist at a distal end portion thereof, the side balloon having an inflatable portion and a proximal waist portion extending proximally from the inflatable portion, the inflatable portion positioned at a location between the proximal and distal waists of the main balloon, the inflatable portion extending radially relative to the main balloon when the side balloon is inflated, the method comprising: (a) positioning a proximal open end of the side balloon proximal waist and a proximal open end of the main balloon proximal waist with outer surfaces adjacent to each other and in fluid communication with the main inflation lumen at the distal end portion of the catheter shaft; and (b) simultaneously securing the side balloon proximal waist, the main balloon proximal waist, and the distal end portion of the catheter shaft together at a single proximal balloon joint while maintaining fluid communication between the side balloon proximal waist, the main balloon proximal waist, and the main inflation lumen.
