Abstract: The present disclosure relates to vascular devices such as guidewires and microcatheters having integrated coil sections for optimizing torquability, flexibility, and ability to shape and maintain the distal tip. A guidewire device includes a core and a tube structure coupled to the core such that at least a portion of the core passes into the tube structure. A distal section of the tube structure includes a spiral cut arrangement that configures the distal section as an integral coil integrally incorporated as part of the tube structure. The integrated coil configuration increases the flexibility of the tube structure to reduce the tendency of resilient forces from the tube structure to disrupt a shaped distal tip of the guidewire device.
