Arrangement for implanting stent elements in or around a hollow organ

An arrangement for installing at least one stent element in a hollow organ, comprising:

• at least one shaft with a proximal end and a distal end having an atraumatic tip, a plurality of independent, single piece stent elements, said stent elements are arranged on an axial wire (L) inside the shaft and the shaft prevents an expanding of the stent elements, wherein the plurality of independent stent elements are not connected to each other and are spaced apart by one or more spacers that are arranged lengthwise of each other along the axial wire wherein the spacers have a shape complementary to adjacent stent elements, wherein the spacers are not detachably connected to said axial wire and do not expand so that they can be pulled back into the shaft through expanded stent elements wherein the stent elements have an anchor at a proximal end and at a distal end of the stent element, wherein the spacers have an opening therein that provide a form-fitting connection with at least one anchor whereby the stent elements are detachably connected to the spacers, wherein the form-fitting connection is detached by relative radial movement of the stent and the spacer as by expanding the stent element, wherein lateral surfaces of said stents enclose said axial wire at a radial spacing therefrom and wherein a height of said lateral surface of at least one stent element varies across a circumference of said lateral surface and the anchors are arranged along a maximum height of said lateral surface.
