ABSTRACT:
A rotational atherectomy device which includes a handle housing and an exchangeable drive shaft cartridge removably attachable to the handle housing. A rotatable prime mover is carried by a prime mover carriage disposed within the handle housing, the prime mover carriage being longitudinally movable with respect to the handle housing. The exchangeable cartridge includes a cartridge housing which is removably attachable to the handle housing, a longitudinally movable tube which is removably attachable to the prime mover carriage, and a rotatable flexible drive shaft which is removably attachable to the prime mover. The rotational atherectomy device includes a cartridge latch, which removably locks the cartridge housing to the handle housing, and a tube latch which selectively locks the longitudinally movable tube against longitudinal movement with respect to the cartridge housing. The exchangeable cartridge also includes a slide which is longitudinally movable with respect to the cartridge housing among at least three positions: a working position where the slide causes the tube latch to unlock the longitudinally movable tube, a neutral position where the slide causes the tube latch to lock the tube against longitudinal movement with respect to the cartridge housing, and a cartridge unlocked position where the slide causes the tube latch to maintain the longitudinally movable tube in its locked position and unlocks the cartridge latch, thereby permitting the cartridge housing to be removed from the handle housing.
