Abstract:
Die Erfindung betrifft ein Stent-Graft-System (1) mit einem auf einen Durchmesser bezogenen expandierbaren ersten Stent-Graft (2) und mindestens einem zweiten Stent-Graft (3), wobei der erste Stent-Graft (2) zumindest Bereichsweise, eine schlauchförmige Netzstruktur (4) aufweist, die in einem expandierten Modus eine Netzstruktur (4) mit im Wesentlichen kreisrunden, ringförmigen Maschen (5) aufweist, wobei der mindestens zweite Stent-Graft (3) an einem distalen Ende (6) nach außen stehende Widerhaken (7) aufweist, über die der mindestens zweite Stent-Graft (3) an den ersten Stent-Graft (2) im expandierten Modus ankoppelbar ist, wobei der mindestens zweite Stent-Graft (3) mit dem distalen Ende (6) eine mit seinem Durchmesser korrespondierende kreisrunde, ringförmige Masche (5) durchstößt und mit den jeweiligen nach außen stehenden Wderhaken (7) an der kreisrunden, ringförmigen Masche (5) eingreift. Ferner betrifft die Erfindung Verfahren zur Koppelung von Stent-Grafts als Stent-Graft-System.
Abstract:
A device (10) includes an upstream tubular portion (12) from which extends a downstream constriction (14). The downstream constriction (14) is smaller in cross- sectional area than the upstream tubular portion (12). Velocity of fluid flowing through the downstream constriction (14) is greater than velocity of the fluid flowing in the upstream tubular portion (12). A permeable downstream portion (20) is distal to the upstream tubular portion (12). The permeable downstream portion (20) is formed with pores (22) so that the downstream portion (20) is more permeable for fluid flow laterally therethrough than the upstream tubular portion (12).
Abstract:
A method of repairing a partial or complete ACL tear using a biologically active suture combined with a suture anchor. The biologically active material may be an angiogenic material that provides a biological stimulus (such as blood vessel growth) to initiate the repair cascade throughout the tear.
Abstract:
Este é um produto relacionado ao setor de saúde/hospitalar. Refere-se o presente a um inédito stent com balão acoplado para neurocirurgia endovascular, para embolização de aneurisma cerebral, formado por um único dispositivo que é inserido no paciente, liberando o stent na artéria e insuflado o balão diretamente no colo e/ou dentro do aneurisma cerebral, resultando em sua completa oclusão. O modelo em questão oferece muito mais segurança, facilidade e praticidade ao médico profissional e também ao paciente, além de permitir que o procedimento seja feito e finalizado em menos tempo, diminuindo inclusive o risco de morbi mortalidade. Destina-se o presente modelo de stent com balão já acoplado a oferecer inovação ao setor médico, mais especificamente o de cirurgias, oferecendo melhora e aperfeiçoamento técnico profissional que, através do dispositivo em questão, permite melhora da performance e modo/tipo de tratamento do aneurisma cerebral, resultando em maior rapidez no atendimento, redução do tempo de cirurgia, redução de custos, agilidade, objetividade, redução de riscos e complicações, melhor recuperação e cicatrização, dentre outros benefícios.
Abstract:
The present invention relates to an apparatus and methods for pumping blood from the venae cavae to the pulmonary arteries and thereby bypassing the right ventricle of the heart. The apparatus includes a pump and an inflow and outflow cannula. In one embodiment, the inflow and outflow cannula are inserted through a single percutaneous opening into a subclavian vein and advanced into the venae cavae. When the outflow cannula is advanced into a pulmonary artery, it is redirected into same. The pump at a proximal end of the bypass apparatus is disposed in a cavity of the body such as near a patient's rib cage. In operation, blood is carried through the inflow cannula from the venae cavae into the pump and then pumped through the outflow cannula into at least one of the right or left pulmonary artery.
Abstract:
A gastrointestinal administration device comprising an elongated tube or track, an anchor and a channel, which allows the proximal end of the tube or track to be wholly secured inside the mouth from where it passes down the lateral oropharynx to the desired site in the gastrointestinal tract. This system may be used to administer nutrients, fluids, medications, nutraceuticals, dietary supplements and/or non-nutrient gastrointestinal stimulants or other therapies directly to a desired site in the gastrointestinal tract in humans and animals for a variety of purposes including novel applications such as weight and glucose control, local administration of medication and storage of a deposit of a therapeutic agent. It may also be used for monitoring of processes inside the gastrointestinal tract.
Abstract:
Described herein are devices and methods for retracting a sheath from a stent. The retractable sheath comprises a tubular liner having at least a portion concentrically disposed about the stent. The tubular liner comprises a tearable strip having a distal end attached to a retraction device. The retraction device is configured to retract the tearable strip proximally ahead of the everting discontinuous tubular liner.
Abstract:
Die Erfindung betrifft eine radial aufweitbare Gefäßstütze (1), welche eine Mehrzahl von miteinander flexibel verbundenen mäandrierenden Ringelementen (2, 3) aufweist, welche eine Gefäßstütze (1) mit einem proximalen und einem distalen Ende und einer Längsachse definieren, wobei die Ringelemente (2, 3) entlang der Längsachse der Gefäßstütze nebeneinander angeordnet sind und aneinander grenzende Ringelemente (2, 3) durch Verbindungselemente (4) miteinander verbunden sind, wobei zwischen wenigstens zwei aneinander grenzenden Ringelementen (2, 3) Verbindungselemente (4) angeordnet sind, die jeweils mindestens ein aufdehnbares Erweiterungselement mit Sollbruchstelle (10) aufweisen, wobei die Erweiterung in Längs- und/oder in Querrichtung möglich ist und die Sollbruchstellen (10) erst nach einer Überdehnung des Erweiterungselements über dessen maximalen Erweiterungspunkt hinaus brechen.
Abstract:
Devices and methods are configured to allow transcarotid or subclavian access via the common carotid artery to the native aortic valve, and implantation of a prosthetic aortic valve into the heart. The devices and methods also provide means for embolic protection during such an endovascular aortic valve implantation procedure.
