STENT FOR ANGIOPLASTY AND A PRODUCTION PROCESS THEREFOR

摘要

The stent for angioplasty has a body (10) in the form of a generally tubular casing capable of being dilated in use from a radially-contracted position to a radially-expanded position. The body (10) includes a support structure (12) made from a first material capable of withstanding this dilation without losing its structural integrity. A structure (14) made from a second material which has been rendered radioactive following the exposure of the stent itself to a neutron flux is associated with at least a portion of the carrying structure (12).
