ABSTRACT:
An apparatus and method of making a thinwall guide catheter useful in delivery of therapeutic devices through a body vessel. The method comprises braiding a flat wire over the surface of a cylindrical core, placing a heat bondable polymer tube over the braid, surrounding the polymer tube with a heat shrink sleeve, heating the assembly to a temperature and for a time period sufficient to expand the core into braid interstices and bond the polymer tube to substantially only the outer surface of the braid and finally removing the heat shrink sleeve and core. The resulting guide catheter has approximately half the wall thickness of prior guide catheters and has excellent column stiffness and kink resistance.
