A first medical instrument includes a flexible catheter having a distal end which has a substantially bullet-nose shape, which is insertable into a body lumen of a patient, and which has at least one guidewire passageway opening. The first medical instrument also includes a medical guidewire having a working portion extendable beyond the at-least-one guidewire passageway opening. A second medical instrument includes a flexible catheter, a medical guidewire having a working portion extendable beyond the distal end of the catheter, and at least one wire length counter which is operably connectable to the medical guidewire to measure a length of the working portion being extended beyond the distal end of the catheter. A third medical instrument includes a flexible catheter, a medical guidewire, and a force/torque-limiting clutch operatively connectable to the medical guidewire. |
