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: A medical device that comprises a rim defining a loop in a plane and defining a width measured perpendicular to the plane, at least one wire coupled to a distal end of the rim and extending proximally from the distal end out of the plane to a proximal end of the rim, the at least one wire having a cross-sectional dimension measured perpendicular to a longitudinal axis of the at least one wire, the cross-sectional dimension being smaller than the width of the rim, and a sheath configured to cover at least a portion of the rim and a portion of the at least one ware.
