Abstract: The present invention relates to tubular radially expansible metal structures, having an abluminal wall, a luminal wall and a radial wall thickness therebetween with struts defining through-apertures in the wall, the structure further defining a plurality of expansible rings arranged adjacent one another along the longitudinal axis of the structure, each of the rings defining at least one bridge strut, and adjacent rings being linked by a bridge extending between adjacent bridge struts on adjacent rings. The bridges, a plurality of which are distributed throughout the length of the tubular structure and are configured and arranged to divide the tubular structure into axially spaced and electrically insulated sections, advantageously exhibit reduced electrical conductivity throughout their wall thickness. The present invention relates furthermore to a method of manufacturing such a tubular structure, as well as a method of visualizing a bodily lumen supported by such a tubular structure deployed therein.

Abstract: The present invention relates to an implant 100 which comprises a plurality of electrically-conductive closed loops (300A, 300B, 300C, 300D; 120A, 120B, 120C, 120D each constituted from a plurality of loop portions such as struts (400, 500). The loops together form apertured walls of a cage with an interior volume, and the portions in any one said loop providing electrically-conductive pathways within which eddy currents are liable to be induced when the implant is subjected to an time-dependent external magnetic field, with each said loop comprising at least first and second said pathways. The implant is characterized in that the first and second pathways are arranged such that, in any particular magnetic field, the direction of the eddy current that would be induced in the second pathway is the reverse of the direction of the eddy current that would be induced in the first pathway, so as to mitigate the tendency of the implant to function in said magnetic field as a Faraday cage.

Abstract: The invention relates to a method for linking nucleic acid and/or glycosaminoglycan or glycosaminoglycan mimetics to a polar/hydrophilic material, characterized by contacting a nucleic acid and/or glycosaminoglycan and a polar/hydrophilic material with each other in the presence of a solution being 20 to 100 percent saturated with a non-chaotropic salt and removing said solution from the nucleic acid and/or glycosaminoglycan—polar/hydrophilic material.
