    Abstract: A rotational atherectomy device including a drive shaft rotatably extending through an outer tubular member to rotate a cutting member positioned at a distal end thereof. The rotational atherectomy device further includes an elongate penetrator extendable distal of the cutting member a predetermined maximum distance and configured to stabilize the cutting member as the cutting member engages an occlusion to control the trajectory and advancement of the cutting member through the occlusion.

    Abstract: An atherectomy system may include an atherectomy apparatus including a drive housing, a catheter shaft extending distally from the drive housing, and a rotatable drive shaft extending within the catheter shaft and operably coupled to the drive housing, the rotatable drive shaft having a guidewire lumen configured to receive a guidewire; and a guidewire management device including: a frame including at least one frame rail extending longitudinally; a movable tray slidably coupled to the at least one frame rail; and a guidewire locking element fixed to the frame. The drive housing may be releasably secured to the movable tray.

    Abstract: Guide extension catheters and methods of manufacturing and using guide extension catheters are disclosed. An example guide extension catheter may include a distal sheath having a proximal opening, a distal opening, and a central lumen extending therebetween. The guide extension catheter may also include a proximal shaft having an outer diameter smaller than an outer diameter of the distal sheath, the proximal shaft including a distal opening. The guide extension catheter may also include a coupling member for securing the distal sheath to the proximal shaft. The coupling member may include a distal portion attached to the distal sheath and a proximal portion disposed within the distal opening of the proximal shaft.
