Vorrichtung zur Korrektur der Lage eines Stents

摘要

It is known to place short stents in blood vessels, in the ureter, in the urethra or the like for dilation or keeping-open of a stenosis, the stents having perforations and being made, for example, of knitted wire mesh. It may happen that the stents are falsely positioned from the start or are displaced. For example, they may come to rest in the urethra in the region of the urethral sphincter, so that the latter is no longer effective. The invention therefore proposes a device for correcting the position of such a stent with a guiding part, which is characterised by an elongate wire part (2) provided on its front end (4) with radially erectable wire sections (9).
