Patent abstract
A guidewire is provided with first and second helical members at the distal end of the guidewire. The helical members enmesh with each other in a retracted state. The second helical member is extended from the first helical member by rotating a tubular member and core member relative to each other. This causes the first and second helical members to be driven apart from each other along a helical path defined by the engagement between helical members.
