<p>Disclosed herein is a flexible composite drive shaft (20) used in the field of flexible vascular atherectomy catheters for connecting a rotating drive means and a rotatable working member. The flexible composite drive shaft (20) includes a core (22) of specially selected highly elastic memory alloy surrounded by a flexible torsional reinforcing member (28) and a coating (34) made of polymetric material which penetrates the interstices between the reinforcing member (28) and the outer surface of the core (22). Cooperation between the core (22), the reinforcing member (28) and the interpenetrating polymer coating (34) provides a composite drive shaft.</p> |
