摘要:
Among other things, there are disclosed embodiments of belts or bands that can be used in treatments for tricuspid valve regurgitation. In some embodiments, such belts may be heat-set in a particular configuration to effectively decrease tricuspid annulus when deployed around the atrioventricular groove. Embodiments include one or more tensioning sutures for applying cinching or tightening to belts when deployed, and structure for effectively distributing force during such tightening.

The invention relates to a heart implant comprising an expandable closure element (1), particularly configured to close or at least reduce a remaining gap between the closed leaflets of a heart valve, preferably the mitral valve, the closure element (1 ) having an axial extension between a lower end (1 b) and an upper end (1a), at least one anchoring element (2), particularly expandable anchoring element (2), preferably for fixing the heart implant to a lumen of the heart, being attached to the closure element (1 ) at the lower (1 b) and/or upper end (1a), preferably only at one of these ends, wherein the closure element (1) comprises adjustment means (6a, 6b) for variable adjusting the radial cross section of the closure element (1) by changing the distance between the lower end (1b) and the upper end (1a) of the closure element (1).
摘要:
A radially expandable, tubular stent, includes a first section having a first crush resistance force and a second section have a second crush resistance force, wherein the first crush resistance force is less than the second crush resistance force. The first section is connected to the second section to form a tube, connection of the first and second sections extending in an axial direction of the tube.

Systems, devices and methods related to various heart valve implants and for delivery of those heart valve implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. Anchors secure the implant to tissue and collars are used to decrease the angle between the struts and contract the frame. The implant thus expands from a first size inside of a delivery catheter, to a second and larger deployed size inside the heart to engage and anchor with the tissue, and then to a third and contracted size to re-size the annulus and/or provide a secure fit for a replacement heart valve. Various delivery systems including imaging capabilities for precise delivery, positioning and anchoring of the various implants are further described.
摘要:
There is disclosed a synthetic joint stabilisation device (10) and associated assembly, the device having a particular use in a method of stabilising a dislocated acromioclavicular joint. The joint stabilisation device (10) comprises a first elongate portion (22) forming a first free end (24); a second elongate portion (26) forming a second free end (28) which is opposite the first free end; and an integral eye (30) provided at a location which is between the first and second free ends, the eye serving for securing the device to a bone (19) of a patient. The device (10) is at least partly tubular so as to define an internal cavity (32), said part, of the device being of a woven material. One of the first and second elongate portions (22, 26) extends into the internal cavity (32) through a wall (34) of the other one of the first and second elongate portions at a first location (36) along a length of said other portion, and then extends out of the internal cavity at a second location (38) which is spaced along a length of said other portion from the first location, to thereby form a loop (40) which defines the eye.
摘要:
Die Erfindung betrifft eine Herzklappenprothese mit einem Klappengestell (2), an welchem mehrere Klappensegel (8) befestigt sind, sowie einem sich axial an das Klappengestell (2) anschließenden Befestigungsbereich zur Befestigung in einem Blutgefäß, wobei in dem Befestigungsbereich ein Stabilisierungsring (14) angeordnet ist, welcher eine vorgegebenen Form und einen vorgegebenen Durchmesser des Befestigungsbereiches definiert und zumindest eine Solldehnungsstelle (22) aufweist, welches es ermöglicht, den Stabilisierungsring (14) durch eine radiale Krafteinwirkung auf seinen Innenumfang aufzuweiten.
摘要:
A prosthetic device for implanting in a patient's heart includes (i) a therapeutic device capable of restoring function to a native heart valve; and (ii) at least one sensor including a body, an inductor coil disposed within the body, and a capacitor in communication with the inductor coil, the at least one sensor being coupled to the therapeutic device, and being configured to monitor proper function of the therapeutic device within the patient's heart.
摘要:
Certain embodiments described herein relate to expandable, reversible implants. In an embodiment, the implants are controllable by way of at least one biochemical, chemical, or physical means. In an embodiment, the implants are programmable and/or pre-programmed for a particular level of expansion and/or contraction. In an embodiment, the implants are controlled remotely from a control source that is external to the subject's body.
摘要:
An adjustable annuloplasty device (1) comprising a tube (2) having a basically annular shape or adopted to be brought into an annular shape. At least one, preferably three, portion of an outer wall (3) or the whole outer wall of the tube (2) is more rigid than opposite portion(s) of an inner wall (4) or the whole inner wall (4). The inner wall is arranged nearer to an inside (5) area defined by the annulor shape than the outer wall (3). The inner wall (4) is adapted to be displaced inwardly at least along less rigid portion(s) of the circumference upon actuation by at least one actuation element (10) while the outer wall (4) remains basically constant.
