Abstract
Surgical and percutaneous devices for closing tissue, for example, the left atrial appendage, may have an elongate body with a stiffened proximal portion, a flexible middle portion, a distal portion, a closure element with a loop having a continuous aperture therethrough, and a suture loop. The closure devices may have a malleable member attached to the elongate body that may be configured to retain a curve after a force is applied to the malleable member. System and methods for closing the left atrial appendage may utilize a closure device and a curved guide device, and the closure device and curved guide device may be self-orienting.
