two parallel crossbars 12 13 that each connect one arm 8 9 in one pair 6 to one arm 10 11 in the other pair 7 the crossbars 12 13 are equally long and are connected to the arms 8 9 and 10 11 at equal distance from the connections 14 15 the pairs 6 7 of arms are thus kept parallel by the crossbars 12 13 the crossbars 12 13 are attached to the arms 8 9 and 10 11 near the connection ends 14 15 the clip 2 is made of a memory metal such as nitinol and in fig2 it is shown in a second state where the arms 8 9 and 10 11 in the pairs are parallel and the bent portions 16 in their ends are brought in close proximity to each other the memory material of the clip 2 biases the clip 2 towards its second closed state in a first state the arms 8 9 and 10 11 in the pairs are opened forming a v as the angle in their connections 14 15 is increased the clip 2 is capable of grasping the mitral leaflets 4 5 at their free edges and binds the edges together by capturing the leaflets 4 5 in the first state of the clip 2 and keeping them together in the second state of the clip 2 where the arms are closed and parallel the clip 2 is inserted into a beating heart 1 by using a catheter referring to fig3 and.
