The invention includes a novel method and system to achieve leaflet coaptation in a cardiac valve percutaneously by creation of neochordae to prolapsing valve segments. This technique is especially useful in cases of ruptured chordae, but may be utilized in any segment of prolapsing leaflet. The technique described herein has the additional advantage of being adjustable in the beating heart. This allows tailoring of leaflet coaptation height under various loading conditions using image-guidance, such as echocardiography. This offers an additional distinct advantage over conventional open-surgery placement of artificial chordae. In traditional open surgical valve repair, chord length must be estimated in the arrested heart and may or may not be correct once the patient is weaned from cardiopulmonary bypass. The technique described below also allows for placement of multiple artificial chordae, as dictated by the patient's pathophysiology.

The invention provides an expansion screw set, a hollow nail and an interior nail. The expansion screw set is composed of the hollow nail and the interior nail. The hollow nail has a hollow structure. A first thread and a second thread are provided for the inside and the outside of the hollow nail. The interior nail has a third thread. The hollow nail could nail an object through the first thread. The third thread of the interior nail corresponds to the second thread of the hollow nail. Therefore, the interior nail can be fastened into the hollow structure after the interior nail is nailed into the hollow nail. Moreover, the hollow nail has a separation line which runs parallel to the penetration direction of the hollow structure. Alternatively, the hollow nail has a plurality of penetration holes which is vertical to the penetration direction of the hollow structure. After the interior nail is nailed into the hollow structure, the separation line can be stretched out through the interior nail. Alternatively, contents within the hollow structure are squeezed to the outside from the penetration holes through the interior nail.

A light provider for an umbrella and stand assembly, comprising a body releasably attachable to the assembly, a source or sources of electric light carried by the body, to direct light away from the body, and incident light responsive means on the body to provide electrical energization for the light source, the means configured to receive incident light from a direction or directions spaced away from light directed from the source or sources.

A jewelry clasp having a pair of bodies at the free ends of a piece of jewelry affixed together by magnetic forces. Each body has a magnet means having north and south poles that are aligned along the longitudinal center line of the clasp with opposite poles abutting each other to hold those bodies in the affixed relationship. There is a safety catch on one of the bodies having a protrusion extending therefrom that overlaps the other body to hold the bodies together. As the protrusion is moved into its latched position, the other body is displaced along the longitudinal centerline to misalign the respective magnetic means, and when the protrusion seats in its latched position, the magnetic means realigns by the magnetic attraction between the magnetic means creating an click that can be heard and/or felt by the wearer to confirm that the bodies are properly affixed together.
