(EN) DEVICE AND METHOD FOR TACKING PLAQUE TO BLOOD VESSEL WALL
(FR) DISPOSITIF ET PROCÉDÉ POUR AGRAFER UNE PLAQUE À UNE PAROI DE VAISSEAU SANGUIN
Abrégé
(EN)
A plaque tack device for treating atherosclerotic occlusive disease is formed as a thin, annular band (30, 80, 90, 100, 110) of durable, flexible material having a plurality of barbs or anchoring points (33, 34) on its outer periphery for preventing it from being dislodged. The plaque tack may be used with a balloon angioplasty procedure or as a de novo treatment for blood vessel blockage to reopen the vessel lumen for desired blood flow. It has a width that is small relative to its diameter, to minimize the amount of foreign structure placed in the blood vessel. One or more tacks may be applied in positions along a plaque accumulation site as needed to stabilize the site and/or hold pieces of plaque out of the way of blood flow. The barbs of the tack may be pressed into the plaque and/or blood vessel walls by balloon expansion. Related methods of deployment and delivery devices are provided for insertion of the plaque tack in a compressed state into the blood vessel and expanding it back to its annular shape for holding plaque against the blood vessel walls.

L'invention concerne un dispositif d'agrafage de plaque destiné à traiter une maladie occlusive athérosclérotique formé sous forme de bande annulaire fine (30, 80, 90, 100, 110) de matériau flexible durable ayant une pluralité de barbes ou points d'ancrage (33, 34) sur sa périphérie externe pour l'empêcher d'être délogé. L'agrafage peut être utilisé avec une procédure d'angioplastie à ballonnet ou en tant que traitement de novo pour un blocage de vaisseau sanguin pour rouvrir la lumière du vaisseau pour un écoulement de sang souhaité. Il a une largeur qui est plus petite relativement à son diamètre, pour minimiser la quantité de structure étrangère placée dans le vaisseau sanguin. Une ou plusieurs agrafes peuvent être appliquées dans des positions le long d'un site d'accumulation de plaque le cas échéant pour stabiliser le site et/ou maintenir des pièces de plaque à l'extérieur de la circulation du sang. Les barbes de l'agrafe peuvent être pressées dans la plaque et/ou les parois de vaisseau sanguin par dilation du ballonnet. Des procédés apparentés du déploiement et des dispositifs d'administration sont proposés pour insertion de l'agrafe de plaque dans un état comprimé dans le vaisseau sanguin et pour le redilater vers sa forme annulaire pour maintenir la plaque contre les parois de vaisseau sanguin.
