A medical having a proximal and a distal end, that is preformed to assume a superimposed structure at an implantation site but can be made to take on a volume-reduced form making it possible to introduce it by means of a micro-catheter and a guide wire arranged at the proximal end, with the implant in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments. The implant has a tapering structure at its proximal end where the strings or filaments converge at a connection point.

An endoluminal device can be configured for precise positioning during deployment within a vessel. The endoluminal device can be a tack, stent, vascular implant or other type of implant. The endoluminal device can have circumferential member with an undulating configuration having multiple inward and outward apexes and struts extending therebetween. Two of the struts can be used to establish a foot for the precise positioning of the device during deployment. A method of placing the endoluminal device can include withdrawing an outer sheath such that a portion of the endoluminal device is expanded prior to the rest of the endoluminal device.

The present invention relates to a stent delivery device having: a first support rod into which a first movable body is inserted; a fixed magnet; and a second support rod into which a second movable body is inserted, wherein a first driving magnet included in the first movable body and a second driving magnet included in the second movable body rotate relative to each other by means of the control of an external magnetic field at a predetermined angle around an axis in a first direction with respect to the fixed magnet, thereby separating a first coupling piece and a second coupling piece from a first coupling groove and a second coupling groove and enabling a stent to unfold.

An implantable prosthetic valve comprises an annular frame that is radially expandable from a radially compressed state to a radially expanded state. The frame has an inflow end, an outflow end, and a longitudinal axis extending from the inflow end to the outflow end. The prosthetic valve also comprises a plurality of leaflets positioned to regulate a flow of blood from the inflow end to the outflow end of the frame, and a skirt assembly. The skirt assembly comprises a laminate having a textile layer sandwiched between a first encapsulation layer and a second encapsulation layer. The first and second encapsulation layers are made of an elastomer and the textile layer comprises a first set of yarns and a second set of yarns interwoven with the first set of yarns, wherein the first and second sets of yarns are non-perpendicular and non-parallel to the longitudinal axis.

An annular mesh expandable radially from a compact diameter to a radially-expanded deployed disposition in which the mesh is capable of sustaining a radially outwardly directed resistive force even when flexing its longitudinal axis out of a straight line, the mesh being composed of stenting struts, the stenting struts being arranged in a plurality of zig-zag strings around the circumference of the lumen, with occasional connector struts joining adjacent strings to create a closed circumference unit cell between two such connector struts and two adjacent connected strings there being a plurality of such unit cells arranged in sequence around the circumference between said two adjacent strings; and characterized in that there is a non-constant increment of strut length, serving to displace along the longitudinal axis each unit cell relative to the circumferentially next adjacent unit cell.
