摘要:
An apparatus for providing at least one treatment to at least one tissue having a first structural arrangement configured to expand a first portion at a distal end of the apparatus, a second structural arrangement configured to expand a second portion at the distal end and at least one lumen associated with at least one of the first structural arrangement and/or the second structural arrangement. The first structural arrangement and/or the second structural arrangement can be configured to position the at least one lumen at a particular position with respect to the tissue. A tip is configured to aid in the insertion of the apparatus into the tissue(s).
摘要:
Ein Katheterschlauchsystem hat einen ersten Schlauch, insbesondere einen Mehrlumenschlauch (1), und mindestens einen zweiten Schlauch, z. B. mindestens zwei Einlumenschläuche (2, 3). Die Innenlumen der beiden Schläuche stehen miteinander über eine ausgehärtete Verbindungsmasse in gegenüber einer Umgebung abgedichteter Fluidverbindung. Es resultiert ein Katheterschlauchsystem, bei dem die Schläuche sicher und dicht miteinander verbunden sind.
摘要:
A steerable catheter (100) comprises a flexible catheter body including a proximal shaft section and a distal articulating section, a proximal steering interface coupled to the proximal shaft section, and at least one hollow stiffening member extending through the proximal shaft section. The stiffening member(s) is more rigid than the proximal shaft section and is laterally offset from a geometric cross-sectional center of the proximal shaft section. The steerable catheter further comprises circumferentially spaced lumens extending through the distal articulating section, and pullwires (108) extending through the stiffening member(s) in the proximal shaft section and the respective lumens in the distal articulating section. Each pullwire has a distal end that terminates in the catheter body distal to the distal articulating section and a proximal end that terminates in the steering interface. The steering interface is manipulatable to selectively tension the pullwires to bend the distal articulating section.
摘要:
A system including a catheter and an expandable member. The catheter includes an independent inflation lumen and an separate independent deflation lumen capable of sequential inflation and deflation of an expandable member in rapid succession, such as less than five seconds.
摘要:
A combined multi-lumen central access catheter and an embolic filter including ports proximal and distal the filter for fluid infusion and/or pressure sensing and infusion ports in the catheter to permit infusion of bioactive agents, flushing agents and/or contrast agents. The embolic filter may be removably coupled to the multi-lumen catheter for temporary placement and retrieval under recommended indications.
