Abstract: The present invention relates to apparatuses for cutting and removing occlusive material with imaging capabilities. According to certain aspects, the apparatus includes a catheter body, a rotatable shaft, and an imaging element. The catheter body defines a lumen and includes a distal housing that defines an opening. The rotatable shaft is disposed within the lumen of the catheter body. The rotatable shaft includes a conveying component and a cutting element that is at least partially surrounded by the distal housing. The imaging element is located on the distal housing of the catheter body.

Abstract: The invention generally relates to intraluminal procedures, and, more particularly, to a contra-rotating cutting assembly for use with an atherectomy device to remove occlusive material from an occluded lumen, such as a blood vessel or other body lumen. The contra-rotating cutting assembly includes a rotatable housing having a distal end, an opposing proximal end and a lumen extending between the distal and proximal ends. The housing is configured to rotate about a longitudinal axis in a first direction. The cutting assembly further includes a rotatable cutter head positioned within at least a portion of the lumen of the housing and in coaxial alignment with the housing. The cutter head is configured to rotate about the longitudinal axis in a second direction opposite the first direction.

Abstract: Described here are devices and methods for performing atherectomies. Generally, the atherectomy devices may comprise a handle, a cutter assembly, and a catheter or catheter assembly therebetween. The cutter assembly may include a cutter housing and a cutter comprising a first cutting element and a second cutting element, each of which may be rotated relative to the atherectomy device to cut occlusive material.
