Abstract
A predilation device may comprise a shaft portion and a distal tip having helical threadings. The predilation device may further include a rapid exchange element rotatably coupled to the shaft portion. A guidewire may slidably engage the rapid exchange element and may guide the predilation device to a lesion site. The predilation device may be positioned with the distal tip abutting the lesion. The shaft portion may be rotated, thereby rotating the tip and causing the tip to pass through the lesion and predilate the lesion. In some embodiments, the tip may remove lesion material.
