摘要： A urological guidewire includes a core formed of a first metallic material and extending toward an end of the guidewire. A coil having a plurality of convolutions is disposed 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 is formed to inhibit separation of the different materials forming the coil and the core. The mechanical interlock may include an enlargement at the end of the core and a bonding material fixing the enlargement to the coil. The convolutions may include a penultimate convolution 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 bent back on themselves and directed over or around the bridge to form the mechanical interlock.

摘要： The present invention is a device for insertion into a human or animal body, in a preferred embodiment a perfusion guidewire capable of delivering perfusion fluids to a vascular site while at the same time exhibiting handling characteristics associated with existing non-perfusion guidewires. Preferred embodiments include a perfusion guidewire which closely matches the dimensions and physical characteristics of standard guidewires. Preferred embodiments also permit high pressure perfusion of oxygen-supersaturated solutions, and include a diffuser segment which divides the flow and reduces fluid velocity, thereby providing an atraumatic, non-cavitating, bubble-free delivery to the patient. The invention also encompasses the attachment of a core wire within a tubular housing to provide superior characteristics to such guidewires, balloon catheters and similar devices.
