1. A balloon catheter, comprising:
- an elongate shaft including a proximal section, a midshaft section, and a distal section, wherein a distal end of the proximal section is coupled to a proximal end of the midshaft section, and a distal end of the midshaft section is coupled to a proximal end of the distal section, wherein the distal section includes a distal outer tubular member and a distal inner tubular member disposed at least partially within the distal outer tubular member, wherein the distal inner tubular member defines a first guidewire lumen configured to receive a first guidewire, wherein the midshaft section includes a braid encapsulated in a polymer material;
a first balloon disposed about at least a portion of the distal section, wherein a proximal waist of the balloon is coupled to the distal outer tubular member and a distal waist of the balloon is coupled to the distal inner tubular member;
a second balloon disposed adjacent to the first balloon, wherein the second balloon includes one or more legs connecting the second balloon to the distal section of the elongate shaft and/or the first balloon;
a stent including a proximal open end and a distal open end, wherein the stent is disposed about a portion of the first balloon and a portion of the second balloon, wherein the stent includes a side opening; and
a secondary tubular member having proximal end, a distal end, and a lumen extending therebetween, wherein the lumen is configured to receive a second guidewire, wherein the secondary tubular member is extends through the proximal open end and the side opening of the stent.

Abstract
An illustrative balloon catheter is disclosed. The balloon catheter may include an elongate shaft including a proximal section, a midshaft section, and a distal section. In some embodiments, the midshaft section may include a braid encapsulated in a polymer material. Additionally or alternatively, the midshaft section may include a thermoset polymer material. Additionally, in some cases, the distal section may include a distal outer tubular member and a distal inner tubular member, one or more of which may include a polymer material and, in some cases, a braid. Additionally, some example proximal section may include a metal polymer composite material.
