Abstract
A guidewire, methods of manufacture, and methods of use is described. The guidewire may include a core having one or more preformed ribs along a portion thereof. The ribs may form a portion of the outer surface of the guidewire or form a texture or shape of the outer surface of the guidewire. The ribs and outer texture of the guidewire can beneficially help the guidewire remain in a desired location in a body and help prevent or limit migration. Forming the ribs on the outer surface of the core may enable the guidewire to have greater rigidity and stiffness. The core may include a reduced diameter region distal of the ribs. The guidewire may include a cap over the reduced diameter region of the core.
