Expandable tool having helical geometry
An expandable downhole tool for use in an oil well, including a flexible member rolled into a helix and comprising first and second lateral edges on opposing lateral ends of the member. The flexible member is selectively changeable between a compressed configuration wherein the transverse cross-section of the flexible member has a first diameter, and an expanded configuration wherein the transverse cross-section of the flexible member has a second diameter, the second diameter larger than the first diameter.
