| 摘要 |
The invention relates to a radially widenable stent (1) comprising a plurality of meandering ring elements (2, 3) which are flexibly connected to one another and which define a stent (1) having a proximal and a distal end and a longitudinal axis, wherein the ring elements (2, 3) are arranged next to one another along the longitudinal axis of the stent and adjacent ring elements (2, 3) are connected to one another via connection elements (4), wherein connection elements (4) are arranged between at least two adjacent ring elements (2, 3), each having at least one expandable widening element with a predetermined breaking point (10), wherein the widening is possible in the longitudinal and/or the transverse direction, and the predetermined breaking points (10) only break after an over-expansion of the widening element beyond the maximum widening point thereof. |
