    摘要： A heart valve prosthesis for use in a heart includes an orifice defining a lumen therethrough for blood flow. An occluder is carried in the orifice and is movable between an open position which allows blood flow through the lumen and a closed position in which flow through the lumen is blocked. A suture cuff coupled to the orifice extends around an outer circumference of the orifice and is used for attaching the heart valve to a heart tissue annulus using sutures. The sutures are knotted proximate the suture cuff to secure the cuff to the annulus. A suture guard is coupled to the suture cuff and is movable between an open position in which the suture knot is exposed and a closed position in which the suture, suture knot and suture cuff are covered.

    摘要： The invention relates to a prosthetic heart valve (100) for an endoprosthesis (1) used in the treatment of a stenotic cardiac valve and/or a cardiac valve insufficiency. The prosthetic heart valve (100) comprises of a plurality of leaflets (102), which consist of a natural and/or synthetic material and have a first opened position for opening the heart chamber and a second closed position for closing the heart chamber, the leaflets (102) being able to switch between their first and second position in response to the blood flow through the heart. In addition, the prosthetic heart valve (100) comprises a leaflet support portion (103), consisting of biological and/or synthetic material for mounting of the prosthetic heart valve (100) to a stent (10), and a bendable transition area (104) which forms a junction between the leaflets (102) and the leaflet support portion (103), the transition area (104) progressing essentially in a U-shaped manner similar to a cusp shape of a natural aortic or pulmonary heart valve for reducing tissue stresses during opening and closing motion of the leaflets (102). The invention further relates to an endoprosthesis (1) comprising a prosthetic heart valve (100) and a stent (10).

    摘要： The present disclosure relates to a device for compressing a stent or a stent with a prosthetic heart valve affixed thereto, as well as a method for loading a stent into a medical delivery system. The device may comprise a compressing mechanism designed so as to exert a compressive force in radial direction on at least parts of a stent accommodated within the compressing mechanism such that the cross-section of the stent is reduced to a predefinable value at least at certain areas. The device may further comprise a manipulating mechanism moveable relative to the compressing mechanism for moving at least one clamping means in the radial direction in order to adjust the internal cross-sectional diameter of the compressing mechanism.

    摘要： A device for treating cardiac disease of a heart having an upper portion and a lower portion divided by an A-V groove, the device including a jacket adapted to be secured to the heart, and a non-adherent material in association with the jacket. The jacket is fabricated from a flexible material defining a volume between an upper and a lower end, the jacket being adapted to be adjusted on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain expansion of the heart beyond the maximum adjusted volume during diastole and permit substantially unimpeded contraction of the heart during systole. As a result of the flexible material, the jacket allows unimpeded diastolic filling of the heart. Also described is a method for treating cardiac disease including surgically accessing the heart, applying the treatment device of the invention, securing the treatment device to the heart, and surgically closing access to the heart while leaving the treatment device on the heart.
