Title
(EN) AGGRESSIVE FEATURED CLIPS WITH IMPROVED TISSUE RETENTION
(FR) AGRAFES À CARACTÉRISTIQUES AGRESSIVES À RETENUE DE TISSU AMÉLIORÉE
Abstract
(EN)
A system for treating tissue includes a capsule including a channel extending therethrough; first and second clip arms each extending from a proximal end to a distal end, the proximal ends being received within the channel of a capsule to be moved between an open tissue receiving configuration; and a closed tissue clipping configuration. The first clip arm includes a first tissue retention feature at a distal portion thereof configured to pierce through a target tissue when in the tissue clipping configuration and subsequently release the target tissue when the clip arms are moved to an at least partially open configuration. The second clip arm includes a second tissue retention feature at a distal portion thereof configured to pierce and retain the target tissue thereon when in both the closed tissue clipping configuration and the open tissue receiving configuration.
(FR)
La présente invention concerne un système de traitement de tissu qui comprend une capsule comprenant un canal s'étendant à travers celle-ci ; des premier et second bras d'agrafe s'étendant chacun d'une extrémité proximale à une extrémité distale, les extrémités proximales étant reçues à l'intérieur du canal d'une capsule à déplacer entre une configuration de réception de tissu ouverte et une configuration d'agrafage de tissu fermée. Le premier bras d'agrafe comprend un premier élément de retenue de tissu au niveau d'une partie distale de celui-ci configuré pour percer un tissu cible lorsqu'il est dans la configuration d'agrafage de tissu, et libérer ensuite le tissu cible lorsque les bras d'agrafe sont déplacés vers une configuration au moins partiellement ouverte. Le second bras d'agrafe comprend un second élément de retenue de tissu au niveau d'une partie distale de celui-ci configuré pour percer et retenir le tissu cible sur celui-ci lorsqu'il est à la fois dans la configuration d'agrafage de tissu fermée et dans la configuration de réception de tissu ouverte.
