Abstract:
An elongated guidewire comprising:a) an elongated core member having a proximal core section with proximal and distal ends and a distal core section with proximal and distal ends;b) a tubular connecting element disposed on the distal end of the proximal core section having a port in a distal end thereof and an inner lumen extending therein;c) the proximal end of the distal core section having an enlargement with at least one transverse dimension greater than a transverse dimension of an adjacent portion of the proximal end and extending through the port in the distal end of the tubular connecting element and into the inner lumen therein; andd) a mass of hardened material disposed about at least a portion of the enlargement providing mechanical interlocking and configured to produce a torque transmitting relationship between the distal end of the proximal core section and the proximal end of the distal core section.
