Abstract
An intracorporeal catheter, such as a guiding catheter, employed for intraluminal procedures is disclosed. The catheter generally has an elongated catheter shaft including a polymeric inner layer and a non-radiopaque outer polymeric layer, along with a radiopaque reinforcing structure disposed between the inner and outer layers. In one embodiment, the reinforcing layer consists of multiple drawn filled tubes braided or wound together. The drawn filled tubes may have a stainless steel outer jacket clad over a radiopaque inner core, or the drawn filled tubes may have a radiopaque outer jacket clad over a stainless steel core. In another embodiment, the reinforcing layer may consist of multiple wires containing radiopaque alloys braided or wound together, wherein at least two of the wires consist of different radiopaque alloys. The strands of the reinforcing structure may have a circular or a rectangular transverse cross-sectional shape.
