    摘要： A method and apparatus for reducing mitral regurgitation. The apparatus is inserted into the coronary sinus of a patient in the vicinity of the posterior leaflet of the mitral valve, the apparatus being adapted to straighten the natural curvature of at least a portion of the coronary sinus in the vicinity of the posterior leaflet of the mitral valve, whereby to move the posterior annulus anteriorly and thereby improve leaflet coaptation and reduce mitral regurgitation.

    摘要： A unidirectional handle device for an endoluminal device includes an outer tubular member and an elongate inner member slidably received in the outer tubular member. The unidirectional handle includes a handle member, a needle bearing clutch disposed in the handle member, a control member guide, and shaft rotatable in a single direction disposed within the handle member. The shaft is rotatable in a single direction by its engagement with the needle bearing clutch. The shaft is in rotational engagement with the outer tubular member of the endoluminal device. The outer tubular member is slidable from a distal position to a proximal position when the shaft is rotated in the single direction. The unidirectional handle device provides substantially no backlash of the outer tubular member. In addition, the unidirectional handle device advantageously produces a tension-retaining effect during use.

    摘要： This invention relates to a method for the production of graphene oxide and its use in various applications. The invention provides a method for the preparation of graphene oxide which involves treating a mixture of graphene oxide and impurities with a solution of a base. The impurities in the graphene oxide include oxygen-containing species that are associated with it i.e. bound to the graphene oxide but which are not covalently bonded to the graphene. The graphene oxide of the present invention has improved purity relative to the poorly characterised graphene oxide that is produced by existing methods.
