A system for treating mitral valve regurgitation comprises tensioning device that can be deployed using a delivery catheter. The device includes tension member linking a proximal anchor and distal anchor. The device is constructed from a material having suitable elastic properties such that the device applies a constant tension force between the anchors, while stretching or flexing in response to a heartbeat when positioned across a chamber of a heart. The anchors may include a plurality of arms. In some embodiments, the arms may also flex in response to a heart beat. When positioned across the left ventricle of a heart, the device can reduce the lateral distance between the walls of the ventricle and thus allow better coaption of the mitral valve leaflets thereby reducing mitral regurgitation.

A method for manufacturing a transient voltage suppressing (TVS) array substantially following a manufacturing process for manufacturing a vertical semiconductor power device. The method includes a step of opening a plurality of isolation trenches in an epitaxial layer of a first conductivity type in a semiconductor substrate followed by applying a body mask for doping a body region having a second conductivity type between two of the isolation trenches. The method further includes a step of applying an source mask for implanting a plurality of doped regions of the first conductivity type constituting a plurality of diodes wherein the isolation trenches isolating and preventing parasitic PNP or NPN transistor due to a latch-up between the doped regions of different conductivity types.

A walking aid apparatus comprising a sitting member which a user sits astride and leg links each coupled to a connection provided on the undersurface of the sitting member in such a way as to be free to swing in the forward / backward direction, which improves the stability of the sitting member. The connection is adapted in such a way that a forward / backward swinging fulcrum of the leg links is located above the sitting member. More specifically, the connection is provided with an arc-shaped guide track longitudinal in the forward / backward direction and having the center of curvature above the sitting member, so that each of the leg links swings along the guide track in the forward / backward direction. If the leg links are allowed to swing freely also in the lateral direction, preferably the lateral swinging fulcrum of the leg links is also located above the sitting member.
