Abstract
Devices, systems and methods are provided for tissue approximation and repair at treatment sites, particularly in those procedures requiring minimally-invasive or endovascular access to remote tissue locations. Fixation devices are provided to fix tissue in approximation with the use of distal elements. In some embodiments, the fixation devices have at least two distal elements and an actuatable feature wherein actuation of the feature varies a dimension of the at least two distal elements. In other embodiments, the fixation devices have at least two pairs of distal elements wherein the pairs of distal elements are moveable to engage tissue between opposed pairs of distal elements. Systems are also provided having fixation devices and accessories.
