A magnetically induced radially expandable vascular stent for use inside a human body to hold open a stenosed vascular lumen. The stent comprises a flexible yet non elastic tubular main body, defining a peripheral wall having a radially outwardly expanded limit condition. A plurality of magnets are mounted in closely spaced wall pockets made in the main body peripheral wall. The relative orientation and position of the magnets are such that an equilibrium state is achieved corresponding to the tubular main body radially outward expanded condition, whereby the net effect of magnetic repulsion between the array of magnets is transformed into a synchronous mechanical radial expansion force of the stent tubular main body to an expanded stable condition thereof. |
