Strut Projecting Means Extends Through Hole In Occluder Patents (Class 623/2.24)
  • Patent number: 8979922
    Abstract: A percutaneous heart valve prosthesis (1) has a valve body (2) with a passage (9) extending between the first and second ends (7, 8) of the valve body (2). The valve body (2) is collapsible about a longitudinal axis (10) of the passage (9) for delivery of the valve body (2) via a catheter (18). One or more flexible valve leaflets (3, 4) are secured to the valve body (2) and extend across the passage (9) for blocking bloodflow in one direction through the passage (9). An anchor device (5), which is also collapsible for delivery via catheter (18), is secured to the valve body (2) by way of an anchor line (6). A failed or failing mitral heart valve (101) is treated by percutaneously locating the valve body (2) in the mitral valve orifice (102) with the anchor device (5) located in the right atrium (107) and engaging the inter-atrial septum (103), such that the taught anchor line (6) acts to secure the valve body (2) within the mitral valve orifice (102).

  • Patent number: 8377115
    Abstract: A valve prosthesis for percutaneous placement within a vein is disclosed that includes a valve scaffold and a backflow barrier. The valve scaffold is of a shape memory or resilient material and the backflow barrier is a flap of flexible material attached to the valve scaffold. The valve prosthesis is operable to alternate between open and closed configurations in response to changes in retrograde blood flow pressure. In the open configuration, the valve scaffold has a frustoconical coil shape of consecutive windings with open spaces therebetween and the backflow barrier allows antegrade blood flow through the open spaces. In the closed configuration, the consecutive windings of the valve scaffold are collapsed such that the valve scaffold has a substantially flat profile and the backflow barrier covers the opens spaces of the flattened valve scaffold to prevent retrograde blood flow from leaking there through.

  • Patent number: 6797003
    Abstract: An aspheric soft intraocular lens, having an optical power surface, which may have multiple radii portions or aspherical portions, as well as spherical portions, intended to replace the crystalline lens of a patient's eye, in particular after a cataract extraction. Such an aspheric soft lens is molded in a coined mold. A pair of core pins, positioned within the mold cavity during the lens forming process, will produce a pair of haptic-mounting holes within the lens. As the lenses are subsequently tumbled to remove flash, indentations will form adjacent to the haptic-mounting holes. These indentations allow for tangential attachment of the haptic to the lens which, in turn, enables maximum flexibility without exceeding the width of the optic.
