Abstract
High torque guidewires and methods for making and using them are provided. A guidewire may include an inner core wire movable relative to an outer jacket. The outer jacket includes proximal and distal ends, a lumen extending there between, thereby defining a longitudinal axis, and one or more helical slots adjacent the distal end. The core wire includes a proximal portion, a distal portion slidably received in the outer jacket lumen and terminating in a curved distal tip that extends from the outer jacket distal end, and one or more pins on the distal portion, each pin slidably received in a respective helical slot in the outer jacket such that axial movement of the core wire relative to the outer jacket causes the pin to slide within the helical slot and rotate the distal tip relative to the outer jacket distal end.
