  • Publication number: 20210045868
    Abstract: A stabilized fabric composed of a mesh or a woven fabric is disclosed as are methods of their manufacture, the manufacture of medical devices made using a stabilized fibers and stabilized medical devices are all disclosed. Fabrics can be stabilized by several techniques including: using mechanical, chemical and/or energetic fasteners at warp and weft intersections in the weave; by using various weaving techniques and fibers. Meshes can be stabilized when properly dimensioned and arranged junctions and struts of the necessary properties are used. All of these stabilized fabrics can be made of synthetic polymer materials such as ultrahigh molecular weight PE or PP and expanded PTFE.

  • Publication number: 20200397577
    Abstract: A guidewire may be configured for insertion into a heart of a patient during a procedure such as a transcatheter aortic valve replacement procedure. The guidewire may include a proximal end and a distal end portion. The distal end portion may include (i) a leading section, (ii) a loop structure at a terminal distal end of the guidewire, and (iii) a transition section extending between the leading section and the loop structure. In the absence of applied forces, the leading section is not tangential to the loop structure. With such a configuration, the guidewire may avoid contact with the ventricular septum of the heart when the loop structure is seated within the left ventricle, which may mitigate potential interference with conduction pathways in the ventricular septum, which may in turn mitigate the need for a pacemaker.

  • Patent number: 10722613
    Abstract: Methods of preparing calcification-resistant bioprosthetic tissue include providing fresh biological tissue, cross-linking the tissue, treating the cross-linked tissue with an alcohol for a time sufficient to allow the alcohol to be diffused into the tissue, and treating the alcohol-treated fixed tissue with a polyol for a time sufficient to allow fluid in the tissue to be replaced by the polyol. The methods may include sterilizing the cross-linked tissue in a solution including propylene oxide or peracetic acid either before or after the alcohol treatment step; or drying the alcohol/polyol-treated, cross-linked tissue, sterilizing the dried tissue by exposure to ethylene oxide or peracetic acid, and storing the sterilized tissue in a dry, ambient environment. The treated tissue may be a tissue component for a bioprosthetic valve, a valve assembly for a bioprosthetic valve or a fully assembled bioprosthetic valve incorporating the tissue.
