1. A ligating clip comprising a first jaw and a second jaw, each jaw having a proximal end and a distal end, the jaws being joined at their proximal ends by a hinge, each jaw having an inner face and an outer face, the jaws being pivotable about the hinge from an open operating position, wherein the inner faces of the jaws are positioned about a vessel or duct of a patient, to a closed operating position, wherein the distal ends are joined by a latch and the vessel or duct is compressed between the inner faces of both jaws, a first row of evenly spaced ribs projecting from the inner face of the first jaw and a second row of evenly spaced ribs projecting from the inner face of the first jaw, the rows being spaced from one another about a longitudinally extending center line along the inner face of the first jaw, the ribs of the first row being staggered with respect to the ribs of the second row, the ligating clip comprising at least one rib of the first row comprising
a body extending from the inner face of the first jaw at a fillet and planar wall segments projecting from the fillet that are perpendicular to the inner face of the first jaw, the body facing the longitudinally extending center line of the inner face of the first jaw and comprises a planar top surface, and a pyramid having a sharp tip projecting beyond the body and away from the inner face of the first jaw, the pyramid of the first row extending across the longitudinally extending center line of the inner face of the first jaw, and
at least one rib of the second row comprising
a body extending from the inner face of the first jaw at a fillet and planar wall segments projecting from the fillet that are perpendicular to the inner face of the first jaw, the body of the at least one rib of the second row comprises a planar top surface, and a pyramid having a sharp tip projecting beyond the body of the at least one rib of the second row and away from the inner face of the first jaw, the pyramid of the second row projecting toward the longitudinally extending center line of the inner face of the first jaw, whereby the sharp tips of the pyramids of the at least one rib of the first row and the at least one rib of the second row are configured to impale a wall of a vessel or duct and prevent movement of the clip relative to the vessel or duct when the clip is in the closed position while minimizing tissue trauma.
