Abstract
A balloon activated force concentrator for use in cooperation with an inflatable angioplasty balloon includes at least one elongated flexible panel, an elongated cutting blade mounted on the outside surface of the elongated flexible panel, and an elastic circular band attached to each end of the elongated flexible panel for securing the elongated flexible panel to an angioplasty balloon. Use of this balloon activated force concentrator requires mounting the device on an inflatable angioplasty balloon by inserting the distal end of the angioplasty balloon through one of the circular bands. The balloon activated force concentrator is then advanced over the balloon until the second circular band reaches the distal end of the balloon. At that point, the elasticity of the circular bands straddle the balloon to retain the activated force concentrator securely against the outer surface of the angioplasty balloon.
