The invention is directed to an expandable stent for implanting in a body lumen, such as a coronary artery. The stent has an open lattice structure and is constructed so that at least one end section has a thicker cross-section and corresponding greater radial strength than the remaining sections of the stent.

A pin carriage (1) in a stretcher device is equipped with six wheels, two of which are horizontal. The carriage is moved in a forwards direction by a first segment (3) attached to a leaf spring on the carriage. This segment engages with a second fixed segment secured to a chain being driven in the transport direction. Free expansion in the transport direction is facilitated by the leaf spring and ...
