Abstract: According to one aspect, a method for removing material from a body lumen is disclosed. The method may include positioning a first medical device within the body lumen; and expanding an expandable member at a distal portion of the first medical device from a retracted state to an expanded state. The expandable member may abut the body lumen in the expanded state. The method may further include providing fluid to a fluid lumen of the first medical device, wherein the fluid is deployed into the body lumen; applying an ultrasound signal to the first medical device from a second medical device; and moving the first medical device distally through the body lumen while the expandable member is in an expanded state, to remove material from the body lumen.

Abstract: Automated injection system disclosed in this application advantageously provides physicians with a simplified interface for selecting fluid sources, such as saline, contrast, or a mixture of both, to inject at high pressures. The injector system may comprise a multi-use subassembly, a single-use subassembly, a fitting to fluidly connect the multi-use and single-use subassemblies, a hand held controller, a user interface, and an injector housing.
