Claim:
1. A guide catheter assembly, comprising: an outer sheath having a distal end, a proximal end, and an inner diameter; an inner catheter disposed, at least partially, within the outer sheath, the inner catheter having a distal end, a proximal end, and an outer diameter; and a tether tethering the inner catheter to the outer sheath, the tether including (i) a first end directly connected to the proximal end of the inner catheter, (ii) a first segment disposed within the inner catheter, (iii) a second segment disposed within a space defined by the inner diameter of the outer sheath and the outer diameter of the inner catheter, and (iv) a second end directly connected to the proximal end of the outer sheath; the guide catheter assembly having a first configuration wherein the tether is untensioned, the distal end of the outer sheath is pointing in a first direction, and the distal end of the inner catheter is pointing in the first direction, and a second configuration wherein the tether is tensioned, the distal end of the outer sheath is pointing in the first direction, the distal end of the inner catheter is pointing in a second direction that is different from the first direction, and the tether is oriented at an angle different from both the first direction and the second direction.
