发明名称 Directional guide catheter assembly
摘要 A guide catheter assembly includes an outer sheath and an inner catheter disposed, at least partially, within the outer sheath. A tether tethers the inner catheter to the outer sheath. The guide catheter assembly has a first configuration where the tether is untensioned and distal ends of the outer sheath and inner catheter are pointing in a first direction. In a second configuration of the guide catheter assembly, 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.

主权项 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.
