    摘要: Disclosed is a method for producing a hemocompatible article. A non-thermally stabilized polytetrafluoroethylene membrane comprised of non-oriented fibers is heated to a temperature of around 400° C. and above the gel point of the polytetrafluoroethylene, while the membrane is being applied against a forming mold. The membrane is applied against the forming mold by generating a pressure differential between opposing faces of the membrane to form a conformed membrane. The conformed membrane is then cooled, thereby producing the hemocompatible article.

    摘要: One-piece heart prosthesis implantable in an anatomical position. According to the invention, the artificial left and right ventricles (2,8) have general directions (14, 15) arranged in an asymmetrical V shape, such that said ventricles approach each other as they move away from the means (6, 12) of connection to the natural left and right auricles, and the individual hydraulic actuators (7, 13), associated respectively with said artificial left and light ventricles (2, 8), are arranged near each other, in proximity to said artificial left ventricle (2).

    摘要: The invention is an apparatus and method to perform a surgical procedure within the beating heart. The instrument provides a seal to surround cardiac tissue, thereby defining a segregated surgical field within the body of the instrument. A suction device is preferred to remove blood and fluids from the surgical field so that a surgical procedure can be performed while the heart continues to beat. The instrument is particularly suitable for a procedure to repair defective or diseased cardiac valves, such as the mitral valve; a procedure which previously required that the heart be stopped so that the corrective surgical procedure could be performed.

    摘要: An activating system is provided for a heart valve having a seat (1) and at least one pivoting flap (2a, 2b) mounted on the seat (1). The activating system includes at least one mobile magnetic element (4) connected with said flap (2a, 2b) and at least one fixed magnetic element (3) on the seat (1), with the magnetic elements (3, 4) producing interacting fields that create a force which is exerted on said flap (2a, 2b) during its opening and/or closing movements.

    摘要: Calcification resistant bioprosthetic implants are made from tanned biological materials, such as porcine heart valves, bovine pericardium, human dura mater or the like, which has been impregnated with a calcification-mitigating effective amount of a ferric and/or stannic salt. The impregnated biological materials and processes are particularly advantageous for the preparation of bioprosthetic heart valves. These implants have been found to be highly resistant to calcification in vivo.

    摘要: A tricuspid remodeling annuloplasty ring having two free ends that are upturned in the inflow direction to help avoid unnecessary leaflet abrasion. The free ends are separated across a gap that is large enough to reduce the risk of passing sutures through the conductive system of the heart, yet not too large that support of the septal leaflet of the tricuspid annulus is degraded. The ring may have four sequential segments looking from the inflow side and extending in a clockwise direction from a free end located adjacent the antero septal commis sure after implant. The ring may define an inflow bulge in the first segment and/or an inflow bulge in the fourth segment that help the ring conform to the natural bulges created by the adjacent aorta, thereby reducing stress and the potential for ring dehiscence. Desirably, the ring has variable flexibility, either gradual and/or between or within different segments.
