Abstract
A stent comprising a plurality of annular elements aligned in the longitudinal direction of extension of the stent and selectively expandable between a radially-contracted condition and a radially-expanded condition as well as a series of connecting elements that extend in the longitudinal direction of extension of the stent to connect the annular elements. The annular elements and the connecting elements are made, respectively, of non-biodegradable material and of biodegradable material. The structure of the stent thus comprises a part of non-biodegradable material, destined to remain long-term at the site of implantation, and a part of biodegradable material, destined to disappear within a longer or shorter period after implantation.
