<p>A cable (138, 140, 141, 142) is terminated to a structure internal to an elongated catheter housing (124) to prevent the cable from being pulled out, as when pulled in steering the catheter. The structure may be an ultrasound transducer assembly (102). The catheter may be an intracardiac echocardiography (ICE) catheter. The cable is terminated at a connection made by soldering, looping and tying, gluing, etc. By way of example, the structure, as dimensioned, in cross-section (145), and configured, would not, if pulled, fit into the pull cable passageway. This creates a secure,physical tie in that it does not rely, for its strength, on the surface adhesion afforded by polymer that has been melted onto the cable as a counter to the shear force applied when the cable is pulled.</p> |
