A medical device may include a shaft and an end-effector extending distally of the shaft. The end-effector may be expandable between a collapsed configuration and an expanded configuration. The end-effector may include a proximal nose and a distal body. The proximal nose may have a radial dimension smaller than a radial dimension of the distal body in the expanded configuration. The end-effector may include a plurality of legs and a transition point of each leg may be located between the nose and the distal body along a common plane normal to the shaft. The shaft may include proximal ends of the legs wrapped about one another.
