Beschreibung
Zusammenfassung:	A steerable delivery apparatus for an implantable medical device comprises a shaft extending distally from the handle, the shaft having a steering-member lumen extending through a length of the shaft, and a steering member extending through the steering-member lumen, the steering member having a proximal end portion and a distal end portion. A pull ring is disposed along a distal end portion of the shaft, the pull ring comprising a proximal segment having a first diameter and a distal segment having a second diameter smaller than the first diameter. The distal end portion of the steering member is fixed to the distal segment of the pull ring, and an adjustment mechanism is further provided in the handle, the mechanism operatively coupled to the proximal end portion of the steering member and configured to adjust tension in the steering member so as to adjust a curvature of the shaft.
