Abstract
Exemplary embodiments of the present disclosure can provide a catheter which can include a removal mechanism which can excavate a tubular-organ occluding object. For example, the exemplary catheter can include: a sheath portion which can have a elongated lumen insertable into a tubular-organ. The catheter can further include an insertion member which can have a second elongated lumen which can be arranged free, slidably, and rotatably with respect to the lumen of the sheath portion. The catheter can also include a removal mechanism configured to remove a occluding object of the tubular-organ. The removal mechanism can include a support portion arranged at a distal portion of the insertion member and a plurality of rotating arrangements having at least one blade edge configured to excavate the occluding object. The support portion can have an axis of rotation that intersects an axis of extension of the insertion member.
