摘要： A method of repairing a defective heart valve involves positioning first and second support rings of an annuloplasty device in a first configuration on opposite sides of native heart valve leaflets and activating a contracted state of the annuloplasty device so that a first pitch distance between the first and second support rings in the first configuration is reduced to a second pitch distance that is shorter than the first pitch distance to move the first and second support rings toward each other to pinch the native heart valve leaflets.

摘要： A method of making an annuloplasty implant includes forming first and second support rings arranged in a coiled configuration around an axial direction and forming at least part of the first and second support ring from a carbon fiber material. The first and second support rings can be formed by 3-D printing according to dimensions of a 3-D reconstruction of a heart valve.

摘要： An annuloplasty device is disclosed comprising first and second support rings being configured to be arranged as a coil in a first configuration around an axial direction, wherein the first and second support rings are configured to be arranged on opposite sides of native heart valve leaflets of a heart valve, a stiffening unit, wherein at least part of the first and second support rings comprises an interior channel configured to receive the stiffening unit, wherein insertion of the stiffening unit into the interior channel increases the stiffness of the first and/or second support rings. A method of repairing a defective heart valve is also disclosed.

摘要： Disclosed is a medical system for short time replacement and repair of a native valve, which comprises an artificial valve (502); and a device for collecting and arranging chordae and/or leaflets to hold and/or stabilize the artificial valve in a desired position, the device comprising: a unit for grasping a plurality of chordae and/or leaflets. The system and/or device allows for fast and easy replacement of a native valve, fast and easy positioning of a temporary artificial valve, and more time for medical personnel to make decisions, prepare and/or perform surgery/medical intervention.

摘要： A kit for repairing and/or replacing a mitral valve includes a mitral valve prosthesis and a loop-shaped element with a proximal end, a distal end, and a curved body. A proximal portion of the curved body is sized for positioning on an atrial side of the mitral valve and a distal portion of the curved body is sized for positioning on a ventricular side of the mitral valve. The distal portion has a first curved region with a radius of curvature that is larger than the radius of curvature of a second curved region so that the distal portion passes between heart muscle wall and chordae and circumflex the chordae of the mitral valve when the distal portion is rotated into place at the ventricular side of the native mitral valve.

摘要： A medical device for delivering and retrieving a medical implant is disclosed comprising a sheath, a wire having a distal end and being movable in a lumen of the sheath in a longitudinal direction of the sheath. The distal end comprises a locking structure for receiving and interlock with a complementary mating surface of a medical implant, wherein the locking structure comprises a first locking surface aligned in a first radial direction to lock rotational movement of the implant, when received in the locking structure, around the longitudinal direction. The wire comprises a pivotable locking portion having an open and a closed position, the locking portion has a locking structure with a recess locking movement of the implant, when received in the locking structure, in the longitudinal direction, when the locking portion is in the closed position.

摘要： A medical securing device for securing an object with a securing member into a tissue comprises an elongated sheath comprising proximal and distal ends, and a securing member introduction device having proximal and distal ends, said distal end being configured to extend from the sheath. The medical securing device comprises also a guiding trail. At least one point of the securing member introduction device is configured to travel along said first guiding trail and thereby control a defined movement of the distal end of said securing member introduction device when extending from the sheath and so to introduce the securing member to the object and to secure said object to the tissue with the securing member.
