Description

In Ergänzung zur Voranmeldung lassen sich bestimmte elastische Aufstellkräfte des Rohrdurchmessers bei unveränderter sinuswellenartiger Längskomponente einmal durch Verwendung verschiedener Amplituden und neben der unverändert unterschiedlich auszubildenden seitlichen Brücken auch durch verschiedene spiralige Anordnungen zur Längsachse des Rohres erreichen. In addition to pre-register certain elastic Aufstellkräfte can be achieved even by using different amplitudes and in addition the unchanged different lateral bridges to be formed by various spiral configurations to the longitudinal axis of the pipe of the pipe diameter without changing the sine wave-like longitudinal component. Allen Konstruktionsmöglichkeiten ist die durchgehende Längsstruktur eigen, so daß einerseits ein Aufspießen der Aufdehnungsballons ausgeschlossen wird und andererseits beim Freisetzen der Stütze durch Zurückziehen der äußeren Umhüllung gegebenenfalls bei unbefriedigender Positionierung die Stütze wieder repositioniert werden kann indem man die Hülle unter Drehung wieder vorschiebt. All design options is the continuous longitudinal structure own, so that on the one hand a skewering the Aufdehnungsballons is excluded and can be on the other hand repositioned upon release of the support by retracting the outer sheath optionally at an unsatisfactory positioning of the support back by advancing the sheath while rotating again. Hierzu ist die spiralige Anordnung außerdem hilfreich. For this, the spiral arrangement is also useful.

Claims (2)

1. Stütze (Stent) für kanalikuläre Körperstrukturen (z. B. Blutgefäße, Gallengänge, Speise- und Luftröhre), dadurch gekennzeichnet, daß die Stütze aus einer durchgehenden, röhrenförmigen, selbständig erweiternden, flexiblen Gitterstruktur besteht. 1. support (stent) for canalicular body structures (eg., Blood vessels, bile ducts, esophagus and trachea), characterized in that the support of a continuous, tubular, is self-expanding, flexible grid structure.
2. Stütze nach Patentanspruch 1, dadurch gekennzeichnet, daß die röhrenförmige Stütze aus einer wabenartigen Gitterstruktur besteht aus einem Stück, ohne scharfkantige Lücken mit sinuswellenartigen Längskomponenten, die durch seitliche Brücken unterschiedlich versetzt, verbunden sind. 2. Support according to claim 1, characterized in that the tubular support made of a honeycomb-like lattice structure consists of a single piece, without sharp-edged gaps with sine-wave-like longitudinal components that differ offset by lateral bridges are connected. Die Möglichkeit longitudinaler und querer Verbiegung mit elastischer Aufstellkraft des Rohrdurchmessers wird durch spiralige Anordnung der sinuswelligen Längskomponenten zur Längsachse des Rohres bedarfsgerecht gestaltet. The possibility of longitudinal and bending querer with elastic radial force of the pipe diameter is designed as required by spiral arrangement of the sine-wave component longitudinal to the longitudinal axis of the tube.
