Abstract: The present invention provides a surgical anchor comprising a screw and a coil; said coil having a conical shape, wound around the screw shaft with the first end of the coil being tapered and having a ring circumference smaller than that of the screw head and being engaged to the bottom of the screw head and the second end of the coil being flared with a larger ring circumference and positioned along the screw shaft.

Abstract: A surgical tool, comprising a needle comprising an aperture of sufficient diameter for receiving a screw; a tool, insertable into said aperture for inserting said screw and capable of engaging with and turning the screw; said screw comprising a shaft having threads in a first direction, a head having a bottom face having a flange, and a coil; said coil wound around the screw shaft in an opposing second direction as to the first direction; said coil comprising a coil end which is defined to engage with the flange on the bottom face.

Abstract: The invention is directed to a steerable mandrel comprising a stationary part and a movable part. The stationary part comprises a tubular sleeve having a mantle wall with a longitudinal semi-circumferential opening or weakening, which divides the stationary part into a proximal portion located on a proximal side of the longitudinal semi-circumferential opening or weakening and a distal portion located on distal side of the longitudinal semi-circumferential opening or weakening. The movable part comprises a rod-like member, which is slidable within the proximal portion of the stationary part. The movable part is attached to distal portion of the stationary part, such that relative movement of the movable part in relation to the stationary part causes a bending of the mandrel.
