  • Publication number: 20190290460
    Abstract: A vascular stent (100) comprises a plurality of wave loops. In its natural state, in two of the wave loops which are adjacent in a group, a part of a wave crest of a lower layer wave loop are in a restrained connection with a part of a wave trough of an upper layer wave loop; the other part of the wave crest of the lower layer wave loop passes through the other part of the wave trough of the upper layer wave loop, and the other part of the wave crest and the other part of the wave trough are in a non-contact mutually-suspended connection. Some of the wave crests and wave troughs of the vascular stent (100) are in the non-contact mutually-suspended connection rather than the restrained connection, so that the maximum flexibility is provided to the stent, and meanwhile, the overall stability of the stent is guaranteed. The stent (100) can maintain a good shape during both implantation and the release process, so that safety during release is ensured.

  • Publication number: 20190242010
    Abstract: A method of depositing of a film on a substrate with controlled adhesion. The method comprises depositing the film including metal, wherein the metal is deposited on the substrate using physical vapor deposition at a pressure that achieves a pre-determined adhesion of the film to the substrate. The pre-determined adhesion allows processing of the film into a device while the film is adhered to the substrate but also allows removal of the device from the substrate.
