摘要:
Device for treating mitral insufficiency and a method for producing the device. The device comprises a proximal stent section (222); a distal stent section (224); a central stent section (226) interconnecting said proximal stent section (222) and said distal stent section (226); and at least one biodegradable structure (228), disposed on the central stent section (226). Said proximal stent section (222) and said distal stent section (226) being radially expandable by deployment of said device. Moreover said biodegradable structure (228) is arranged to retain the central section (226) in a contracted shape for a predetermined period after deployment of the device.
摘要:
A device for reshaping a mitral valve annulus (25), said device being elongate and having such dimensions as to be insertable into a coronary sinus (24). The device comprises fixing means (22, 23; 22a, 23a) for fixing the ends of the device within the coronary sinus (24); anda shape changing member (20a; 7; 7a; 9) extending between the fixing means (22, 23; 22a, 23a). The shape changing member (20a; 7; 7a; 9) includes a plurality of adjacent structural cells. The device includes resorbable delay means (21 a; 8; 8a; 10) that in a first configuration retrains at least two of said plurality of adjacent structural elements in a first, relatively elongate state of shape (K; D; E) and wherein the delay means in a second configuration releases said at least two adjacent structural elements to assume a second, relatively shortened state of shape (K'; D'; E'), thereby reducing a length of the shape-changing member (20a; 7; 7a; 9). The delay means (21 a; 8; 8a; 10) moves from its first configuration to its second configuration upon resorbtion of the delay means.

摘要:
Device for treating mitral annulus dilatation. The device comprises a balloon catheter (214) having proximal and distal ends; a lumen (213) extending therethrough; and a balloon (215); the balloon catheter (214) having contracted and deployed states, wherein the balloon (215) comprises a predetermined shape in the deployed state; and a stent (212) having contracted and deployed states, wherein the stent (212) is plastically deformable by the balloon catheter (214) and substantially conforms to the predetermined shape of the balloon (215) in the deployed state of the balloon catheter (214), wherein the stent (212) is configured to apply a compressive load on the mitral valve annulus in the deployed state.
