BALLOON CATHETER
First Claim
1. A bifurcated stent delivery system, comprising:
- an elongate shaft including a proximal section, a midshaft section, and a distal section;
wherein the proximal section includes a tubular member having a plurality of slots formed therein, wherein the slots are arranged in one or more sections having differing slot densities;
wherein the midshaft section includes a guidewire port in fluid communication with a guidewire lumen formed in the shaft;
a main branch balloon coupled to the shaft;
a side branch balloon disposed adjacent to the main branch balloon; and
a stent disposed on the main branch balloon and on the side branch balloon.

Abstract
Balloon catheters and stent delivery systems including bifurcated stent delivery systems are disclosed. An example bifurcated stent delivery system may include an elongate shaft including a proximal section, a midshaft section, and a distal section. The proximal section may include a tubular member having a plurality of slots formed therein. The slots may be arranged in one or more sections having differing slot densities. The midshaft section may include a guidewire port in fluid communication with a guidewire lumen formed in the shaft. A main branch balloon may be coupled to the shaft. A side branch balloon may be disposed adjacent to the main branch balloon. A stent may be disposed on the main branch balloon and on the side branch balloon.
