1. An implantable apparatus comprising:
a body defining a distal end region extending along a distal end region axis; and
two alignable marker elements coupled to the body within the distal end region, wherein each of the two alignable marker elements defines a complementary shape that complements the other alignable marker element such that, when the distal end region is viewed axially, the two alignable marker elements form a fiducial shape indicative of acceptable alignment of the distal end region for positioning at a target site.
