A catheter assembly and related methods having a main balloon, a branch balloon arrangement and a stent. The branch balloon arrangement can include a branch balloon and at least one orientation indicator. The orientation indicator can include visible markings on portions of the side balloon or on inflation segments coupled in fluid communication to the side balloon. The side balloon can have a specific color that is different from a color of the main balloon for improved visualization of the side balloon. The orientation indicator can be helpful in aligning the side balloon relative to features of the stent. The stent can include a side branch opening located between distal and proximal open ends of the stent.

Side balloon identifiers and methods for radial and axial alignment in a catheter assembly

A catheter assembly includes a main catheter branch and a side catheter branch. The main catheter branch includes a main balloon and a side balloon. The side catheter branch includes a transparent portion along at least a portion of a length of the side catheter branch. The transparent portion of the side catheter branch permits viewing of the side balloon through the transparent portion for alignment of the side balloon relative to the side catheter branch. The catheter assembly can further include a stent, wherein the stent includes a lateral branch opening. The transparent portion of the side catheter branch can also provide viewing of the side balloon through the side catheter branch to help align the side balloon with the lateral branch opening.
