Left atrial appendage clipping device and methods for clipping the LAA

An external LAA exclusion clip comprises a clipping assembly comprising first and second opposing clip struts each of the clip struts having a tissue-contacting surface and first and second bias surfaces, a bias assembly connecting the first clip strut to the second clip strut to align the first and second clip struts in a strut plane passing through the tissue-contacting surface. The bias assembly comprises at least one first bias spring connected to the first bias surface of the first clip strut and to the first bias surface of the second clip strut and at least one second bias spring connected to the second bias surface of the first clip strut and the second bias surface of the second clip strut. The first bias spring and the second bias spring are configured to permit movement of the first and second clip struts in the strut plane.
