Alternative designs, materials and manufacturing methods for guidewires. Some embodiments pertain to a guidewire having a core wire including a proximal section defining a proximal end and a distal section defining a distal end. The proximal section having a uniform diameter extending from adjacent the proximal end to adjacent the distal section. The distal section having a reduced diameter relative to the proximal section. A tubular polymer layer having an textured outer profile configured to enhance the ability of a user to grip the tubular polymer layer is disposed about a portion of the uniform diameter proximal section of the core wire.
