  • Publication number: 20210244572
    Abstract: An elastic hosiery formed of a stretchable elastic textile material, wherein the elastic textile material has the elastic property that when a length of unstretched material is stretched to different circumferential lengths, with different yield rates, the pressure exerted by such different circumferential lengths having the same length of unstretched elastic material varies less than 30% over a range of approximately circular circumferences providing a range of yield rates from ?1 to ?2, wherein ?2/?1>1.8. The elastic textile material may be a weft knitted material, and including elastic threads or yarns of an elastic material arranged as inlays in weft direction.

  • Patent number: 9636208
    Abstract: A vascular prosthesis is disclosed, comprising a forked tube, having: an inflow tube with an inflow end; a primary distal outflow branch with a primary distal outflow end; and a secondary proximal outflow branch with a secondary proximal outflow end. The two outflow ends are directed in different directions and the two outflow branches in the vicinity of the bifurcation have different cross-sectional areas. Further, the secondary proximal outflow branch is more curved than the primary distal outflow branch, and the secondary proximal outflow branch in the vicinity of the bifurcation has a smaller cross-sectional area than the primary distal outflow branch. Hereby, energy losses at flow bifurcations is adapted to the bypass situation to even out the level of shear stress, thereby avoiding areas with low shear stress and decreasing the tendency for turbulent flow, thus reducing the risk of graftstenosis.

  • Publication number: 20160166437
    Abstract: An elastic bandage is disclosed, enabling the bandage to be applied with improved ease, predictability and controllability, even on body parts having variable circumference. The bandage comprises an elongate strip of a stretchable elastic textile material, wherein a first set of repeated markings are provided and distributed along the longitudinal direction of the elongate strip for correlation of markings within different turns, allowing turns having the same length of unstretched elastic bandage to be wrapped and stretched around various circumferences with different yield rates. Further, the elastic property of the elongate strip is such that the pressure exerted by such turns having the same length of unstretched elastic bandage varies less than 30% over a range of approximately circular circumferences providing a range of yield rates from ?1 to ?2, wherein ?2/?1>1.8.

  • Patent number: 8945207
    Abstract: A method and apparatus for a removable porous stent to be placed in tubular structures that is unsuitable for permanent stents. The walls of the stent are freely permeable to allow the blood flow. The stent can be used as a carrier of chemotherapy or radiation to be placed in tubular structures for local treatment of cancer. The stent is formed by at least one continuous thread arranged in interconnected loops and having a reversible bind-off at one end of the tubular body, mechanically securing each loop at said end of the tubular body apart from a single releasable loop. This loop is preferably extended beyond the tubular structure of the stent enabling an initiation of the removal at a distance from the treatment site.

  • Patent number: 8758423
    Abstract: A stent device for treating an aneurysm is disclosed. The stent device comprises an expandable balloon with a channel extending through said balloon from one side to another, and a supporting stent connected to said balloon. In an operative disposition, when the expandable balloon is expanded, the supporting stent is arranged at least partly within said channel of said expandable balloon. Further, the supporting stent has walls which are permeable to blood. The stent device may be introduced and removed by endoscopic procedures, with a relatively simple procedure. Thus, the stent device is highly useable for fast and temporary treatment of ruptured aneurysms.
