Abstract: 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.
