摘要：
The present invention relates generally to a tissue closure device and in particular to a tissue closure device having a plurality of configurations providing for delivery and use in minimally invasive proce dures. A tissue closure device (100) is provided from shape memory or super-elastic materials for closing a tissue site opening (50), the device comprising a plurality of tissue anchors (130) extending from a closed loop surface (110) wherein the plane of said tissue anchors is provided at an angle essentially perpendicular with respect to the plane of said closed loop surface；a. wherein said plurality of tissue an chors (130) comprise a proximal end (130p) and a distal end (130d)； said distal end provided for anchoring said device onto tissue (50)； and wherein said proximal end (130p) is fluid with and extends from said closed loop surface (110)； and b. said closed loop surface (110) having a plurality of configurations including: a delivery configura tion (lOOd), an open configuration (1000 ) and a closed configuration (100c) wherein said closed loop surface (110) may undergo a trans formation between one of said plurality of configurations to another； said delivery configuration (lOOd) defining a low profile of said device (100) and adapted for delivery to a tissue site (50) through a small profile access point having a first diameter and wherein said closure device is utilized to close a tissue site having a second diameter such that said second diameter is larger than said first diameter.La présente invention porte de façon générale sur un dispositif de fermeture de tissu, et, en particulier, sur un dispositif de fermeture de tissu qui présentant une pluralité de configurations permettant la distribution et l'utilisation dans des opérations minimalement invasives.
