    摘要: A medical device for grinding substance inside a body lumen includes a rotatable tubular drive shaft, a treatment member connected to the drive shaft, and a tubular member possessing an axially extending lumen that extends throughout the tubular member. The tubular member is mounted on the treatment member and surrounds a portion of the treatment member so that the treatment member is rotatable relative to the tubular member. The treatment member includes a shearing portion, and the tubular member includes a protrusion that projects toward the lumen of the tubular member. The protrusion is located axially in front of the shearing portion and interacts with the shearing portion during relative rotation between the treatment member and the tubular member to shear debris resulting from the grinding of the substance.

    摘要: Disclosed herein are catheters for use with clot treatment systems, and associated devices and methods. The catheter can include an outer sheath, an outer sheath drive component operably coupled to the outer sheath, a guidewire sheath slidably disposed within the outer sheath, a guidewire sheath drive component operably coupled to the guidewire sheath and slidably disposed within the outer sheath drive component, and a clot treatment component. During a clot treatment procedure, the outer sheath drive component can be moved proximally and/or the guidewire sheath drive component can be moved distally to cause corresponding movement of the outer sheath and/or guidewire sheath, respectively, and transition the catheter between a first configuration, in which the clot treatment component can be positioned within the outer sheath, and a second configuration, in which at least part of the clot treatment component can extend beyond the outer sheath.
