Abstract
A delivery catheter for a stent. The delivery catheter may have a distal end and a proximal end. The distal end includes a stent attachment region adapted to receive a stent. The stent may be of the self-expanding type. The catheter further includes a handle at its proximal end and at least one sheath which may at least partially circumferentially cover the stent such as to retain it in a collapsed configuration. The sheath is coupled at its proximal end to an actuator located on the handle portion. The catheter further includes at least one radio-opaque indicator for indicating a rotational orientation of the delivery catheter and/or the stent when observed using medical imaging during implantation of the stent.
