  • Patent number: 9744038
    Abstract: A medical apparatus positionable in a cavity of a bodily organ (e.g., a heart) may constrict a bodily orifice (e.g., a mitral valve). The medical apparatus may include tissue anchors that are implanted in the annulus of the orifice. The tissue anchors may be guided into position by an intravascularly or percutaneously deployed anchor guiding frame. Constriction of the orifice may be accomplished by cinching a flexible cable attached to implanted tissue anchors. The medical device may be used to approximate the septal and lateral (clinically referred to as anterior and posterior) annulus of the mitral valve in order to move the posterior leaflet anteriorly and the anterior leaflet posteriorly and thereby improve leaflet coaptation and eliminate mitral regurgitation.

  • Patent number: 4423772
    Abstract: A heat exchanger comprises a plurality of plates arranged adjacent to each other and provided with mutually corssing corrugation patterns of ridges and grooves which form supporting areas in which the plates abut each other. According to the invention, at least some of the heat exchange passages are defined by plates at least one of which has recessed supporting areas, whereby the volume of the passage is reduced.
