Title
(EN) TISSUE REMODELING SYSTEMS AND METHODS
(FR) SYSTÈMES ET MÉTHODES DE REMODELAGE D'UN TISSU
Abstract
(EN)
Systems and methods for remodeling of tissue, such as heart tissue. In some configurations, the systems and methods are directed toward remodeling of the mitral valve of a patient. The systems and methods can include a first tissue anchor, a second tissue anchor, a suture that extends between the tissue anchors, and a suture lock that secures the suture relative to at least one of the tissue anchors or fixes a length of the suture. The systems and methods can also include a suture trimmer that can trim an excess portion of the suture. In some configurations, the suture lock is reversible to allow for iterative adjustments of the remodeling.

L'invention concerne des systèmes et des méthodes de remodelage d'un tissu, tel qu'un tissu cardiaque. Dans certaines configurations, les systèmes et les méthodes sont dirigés vers le remodelage de la valvule mitrale d'un patient. Les systèmes et les méthodes peuvent comprendre un premier ancrage de tissu, un second ancrage de tissu, une suture qui s'étend entre les ancrages de tissu, et un verrou de suture qui fixe la suture par rapport à au moins l'un des ancrages de tissu ou fixe une longueur de la suture. Les systèmes et les méthodes peuvent également comprendre un dispositif de coupe de suture qui peut ajuster une partie en excès de la suture. Dans certaines configurations, le verrou de suture est réversible afin de permettre des ajustements itératifs du remodelage.
