Title
(EN) DEVICES AND TECHNIQUES FOR ENDOSCOPIC INTRACARDIAC SUTURE PLACEMENT
(FR) DISPOSITIFS ET TECHNIQUES POUR LA POSE D'UNE SUTURE INTRACARDIAQUE ENDOSCOPIQUE
Abstract
(EN)
Intracardiac instruments, systems, and methods of using intracardiac instruments. An instrument comprises an instrument body, an interventional device, and a translucent viewing tip are provided. The instrument body has a proximal portion, a distal portion, a viewing lumen, and an instrument lumen, the viewing lumen having a viewing port in the distal portion and the instrument lumen having an exit port in the distal portion. The interventional device is device positionable in the instrument lumen and extendable from the exit port. The a translucent viewing tip is sealingly coupled to the distal portion over the viewing port and has an outer surface configured to engage cardiac tissue, the exit port being outside the viewing tip. When positioned in a blood-filled space, the viewing tip is configured to displace blood away from the viewing port to allow visualization of the cardiac tissue and the interventional device through the viewing lumen.

L'invention concerne des instruments intracardiaques, des systèmes et des procédés d'utilisation d'instruments intracardiaques. Un instrument comprend un corps d'instrument, un dispositif d'intervention et une pointe de visualisation translucide. Le corps d'instrument a une partie proximale, une partie distale, une lumière de visualisation et une lumière d'instrument, la lumière de visualisation ayant un orifice de visualisation dans la partie distale et la lumière d'instrument ayant un orifice de sortie dans la partie distale. Le dispositif d'intervention peut être positionné dans la lumière d'instrument et s'étendre à partir de l'orifice de sortie. La pointe de visualisation translucide est couplée de manière étanche à la partie distale au-dessus de l'orifice de visualisation et a une surface externe configurée pour venir en prise avec un tissu cardiaque, l'orifice de sortie étant à l'extérieur de la pointe de visualisation. Lorsqu'elle est positionnée dans un espace rempli de sang, la pointe de visualisation est configurée pour déplacer le sang loin de l'orifice de visualisation pour permettre la visualisation du tissu cardiaque et du dispositif d'intervention à travers la lumière de visualisation.
