Abstract:
1. Catheter-deliverable apparatus comprising: a first expandable structure that can be positioned on a first side of a patient's body tissue structure edge; and a second expandable structure that can be positioned on a second side of the patient's body tissue structure edge, wherein each of the first and second expandable structures are expandable from substantially one dimension to a two-dimensional configuration, wherein the first expandable structure is a first V-shaped part having spaced ends, and the second expandable structure is a second V-shaped part having spaced ends, the spaced ends of the second V-shaped part being directly connected to the spaced ends of the first V-shaped part, and wherein the first and second expandable structures are resiliently biased to diverge from one another so that, in use, the tissue structure edge can be received between the first and second expandable structures and a first plane in which the first V-shaped part lies and a second plane in which the second V-shaped part lies form a V-shaped trough; further comprising a third V-shaped part having spaced ends, the spaced ends of the third V-shaped part being directly connected to the spaced ends of each of the first and second V-shaped parts.
