Zusammenfassung: | A catheter system for the introduction and implantation of a stent comprises a catheter (
1
) with an expandable portion (
2
) at its one end, elements at the opposite catheter end intended for communication with means for expanding the expandable portion, and a stent (
3
) made of a material to which a permanent deformation is imparted when the catheter is expanded until the desired insertion diameter is reached, said stent (
3
) being arranged around the expandable portion (
2
) of the catheter, where the stent (
3
) is adhesively connected to the expandable portion (
2
) of the catheter with adhesion forces between stent and support which are less powerful than the shear forces with which the expandable portion (
2
) of the catheter influences the adhesive connection when said portion is expanded, all of the above being obtainable by a method whereby the stent (
3
) is arranged around the expandable portion (
2
) of the catheter, the catheter surface is softened, e.g. by heating, whereupon the stent (
3
) is depressed into the catheter surface. |
