摘要：A urological guidewire includes a core formed of a first metallic material andextending toward an end of the guidewire. A coil having a plurality of convolutions isdisposed around the core at the end of the guidewire, the coil being formed of a second
metallic material different than the first metallic material. A mechanical interlock isformed to inhibit separation of the different materials forming the coil and the core. Themechanical interlock may include an enlargement at the end of the core and a bondingmaterial fixing the enlargement to the coil. The convolutions may include a penultimateconvolution with a first radius of curvature and an ultimate convolution having a second,shorter radius of curvature to form a bridge. In this case, portions of the core can be bentback on themselves and directed over or around the bridge to form the mechanicalinterlock.
