1. A device for guiding a catheter through a patient'"'"'s blood vessels comprising:

  • a catheter guiding tip extending distally at a distal end of the catheter with an outer dimension substantially the same as an outer dimension of the catheter, the catheter guiding tip expanding distally to at least one guiding member with a tip portion having a shape in an uncompressed state that is larger than the catheter outer dimension along at least one axis perpendicular to a longitudinal axis of the catheter, the catheter guiding tip portion being deformable for insertion in a sheath larger than the tip portion when the tip portion is compressed but smaller than the tip portion when the tip portion is not compressed and resilient for resuming the shape in the uncompressed shape when not subject to compression forces, wherein the shape of the tip portion in the uncompressed state is formed as a member extending distally and radially to form a substantially hook-shaped member along an axis perpendicular to the longitudinal axis of the catheter, and the tip portion transitions to a flattened cross-section as the tip portion hooks around to the most distal point of the tip portion.
