Title
(EN) ADJUSTABLE ANNULOPLASTY RING WITH SUBCUTANEOUS ACTIVATION PORT
(FR) ANNEAU D'ANNULOPLASTIE AJUSTABLE POURVU D'UN ORIFICE D'ACTIVATION SOUS-CUTANÉ
Abstract
(EN)
Annuloplasty rings are employed to treat heart valve defects, such as regurgitation. Synching the heart tissue to the ring restores the valve opening to its approximate original size and operating efficiency. Adjustable annuloplasty rings allow for a proper degree of synching both during open heart surgery and over the patient's lifetime. A subcutaneous port may be coupled to an adjustable annuloplasty ring such that an external activation energy generator can be used to heat the adjustable annuloplasty ring and thereby adjust the size of the annuloplasty ring.
(FR)
La présente invention a pour objet des anneaux d'annuloplastie qui sont utilisés pour traiter des défauts de valve cardiaque, tels qu'une régurgitation. La synchronisation du tissu cardiaque avec l'anneau restaure l'ouverture de la valve vers sa taille d'origine approximative et son efficacité de fonctionnement. Les anneaux d'annuloplastie ajustables permettent un degré correct de synchronisation à la fois pendant une chirurgie à cœur ouvert et pendant la durée de vie du patient. Un orifice sous-cutané peut être accouplé à un anneau d'annuloplastie ajustable de telle sorte qu'un générateur d'énergie d'activation externe puisse être utilisé pour chauffer l'anneau d'annuloplastie ajustable et de cette façon ajuster la taille de l'anneau d'annuloplastie.
