ABSTRACT:
An extendable guidewire for insertion within a subject. The guidewire includes an elongated flexible member having a diameter small enough for insertion into a subject and includes an outer member and an inner member. A central passageway extends through a proximal portion of the outer member. The inner member comprises a guidewire extension that is dimensioned to fit within the central passageway for back-and-forth movement with respect to the outer member. The outer member has a movement-limiting portion at its proximal end that cooperates with a movement-limiting portion of the inner member to limit movement of the inner member and frictionally hold the inner member in its extended position.
