Abstract
The present invention is directed to an ultrasonic catheter for delivering ultrasonic energy to a treatment location within a patient's body. In a preferred embodiment, the catheter has proximal and distal portions, the distal portion having an outer tubular member. The catheter, preferably, the distal outer tubular member, is formed, at least in part, of a polymeric material blend having a flexural modulus of elasticity less than about 150 ksi.
