Abstract
A device for removing thrombus from a body cavity is disclosed. The device comprises a flexible wire having a proximal end and a distal end. The device further comprises an elongated shaft having a proximal portion and a distal portion. The proximal portion attached to the distal end of the flexible wire and distally extends therefrom to the distal portion. The device further comprises an expandable member formed helically about the elongated shaft. The expandable member is configured to helically close, defining a collapsed state for delivery and retrieval of the device. The expandable member is configured to helically open, defining an expanded state for removing thrombus from the body cavity. The expandable member has at least one member portion helically extending from the elongated shaft at a predetermined angle, defining a proximally faced opening when the member is in the expanded state.
