Title: MEDICAL DEVICE AND METHOD
Abstract:
A medical device (100) for grinding substance inside a body lumen includes a rotatable tubular drive shaft (114), a treatment member (102) connected to the drive shaft (114), and a tubular member (160) possessing oppositely located distal-most and proximal-most ends, the tubular member (160) including an axially extending to permit passage of a guidewire. The tubular member (160) is positioned in a distal portion of the lumen of the treatment member (102). The tubular member (160) possesses an axial length from the proximal-most end of the tubular member (160) to the distal-most end of the tubular member (160). The axial length of the tubular member (160) is less than an axial length of the treatment member (102), and the treatment member (102) and the tubular member (160) are relatively rotatable.
