EXPANDABLE DEVICE FOR TREATMENT OF A STRICTURE IN A BODY VESSEL

摘要

An expandable and retrievable device for treatment of a stenotic lesion in a body vessel is disclosed. The device comprises a tubular portion including a proximal end and a distal end extending from the proximal end. The tubular portion has a lumen formed therethrough between the proximal and distal ends. The device further comprises an expandable member formed helically about the tubular portion. The expandable member is configured to helically close, defining a collapsed state for delivery of the device. The expandable member is configured to helically open, defining an expanded state for treatment of the stenotic lesion in the body vessel. The expandable member has at least one filter portion that helically extends from the tubular portion at a predetermined angle. This defines a proximally faced opening when the expandable member is in the expanded state.
