Abstract: Among other things, there are disclosed embodiments of belts or bands that can be used in treatments for tricuspid valve regurgitation. In some embodiments, such belts may be heat-set in a particular configuration to effectively decrease tricuspid annulus when deployed around the atrioventricular groove. Embodiments include one or more tensioning sutures for applying cinching or tightening to belts when deployed, and structure for effectively distributing force during such tightening. Embodiments of tensioning members, protective members, and devices and methods for open-surgical placement (e.g. around a heart for annuloplasty) are also disclosed.

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.
