Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.

Abstract: There are shown and described embodiments of closure devices and systems for closing holes in tissue such as those caused unintentionally (e.g. hernia) or intentionally (e.g. openings in the right atrial appendage to access cardiac tissue). Such devices and systems include one or more mesh elements or anchors. In particular embodiments, a closure device includes first and second mesh closure members and a tether or stem connecting them. Embodiments of a delivery device for such closure devices are also described.
