A medical device for minimally invasive removal of tissue from a body lumen, can include: a sheath (12) having a proximal and a distal end; and a tool (41) configured to pass through the sheath (12) and configured to transition from a crimped state to a deployed state and to a closed state, wherein the tool (41) forms an aperture (5) at a distal end, the distal end of the tool having at least one tube loop (18) and at least one wire loop (28), wherein the tool is configured to dissect tissue in the deployed state.
