1. A device for treating a blood flow passage of a patient, the device comprising:
an expandable element configured to be positioned within the passage, the expandable element having a collapsed configuration and an expanded configuration in which the expandable element defines a lumen therethrough;
a reinforcing element positioned within the lumen of the expandable element, the reinforcing element having a collapsed configuration and an expanded configuration in which the reinforcing element defines a lumen therethrough; and
a connector having:
a first portion coupled to the reinforcing element at a first location disposed within the lumen of the expandable element,
a second portion coupled to the reinforcing element at a second location disposed within the lumen of the expandable element, and
an intermediate portion between the first and second portions, wherein the intermediate portion extends over a radially outer surface of the expandable element,
wherein the reinforcing element is coupled to the expandable element via the connector such that expansion of the expandable element causes the reinforcing element to radially expand, thereby creating a perfusion lumen through the device.
