Abstract

Die Erfindung betrifft eine Vorrichtung zur Entfernung von Fremdkörpern und Thromben aus Körperhohlräumen und Blutgefäßen (12) mit mindestens einem Führungsdraht (6, 7), der ein distales Element (2) aufweist, wobei das distale Element (2) radial nach außen hervorstehende Fasern (3) aufweist und die Vorrichtung eine Korb- (1) oder Röhrenstruktur (16) aufweist, die geeignet ist, sich unter dem äußeren Zwang eines Mikrokatheters (13) eng zusammenzufalten und innerhalb des Mikrokatheters (13) transportiert und bei Wegfall des äußeren Zwangs durch den Mikrokatheter (13) zur vollen Korb- (1 ) oder Röhrenstruktur (16) entfaltet zu werden, wobei das distale Element (2) und die Korb- (1) oder Röhrenstruktur (16) einander gegenüber längs verschieblich sind und die Korb- (1) oder Röhrenstruktur (16) distal eine Öffnung aufweist, durch die das distale Element (2) in die Korb- (1) oder Röhrenstruktur (16) einbringbar ist. Mit Hilfe der erfindungsgemäßen Vorrichtung ist ein einfaches und sicheres Entfernen von Thromben (5) aus Blutgefäßen (12) möglich.
