  • Publication number: 20160158039
    Abstract: The invention relates to a medical device for inserting into a hollow organ of the body. The device has a compressible and expandable lattice structure made of webs, which are integrally connected to each other by web connectors and which bound closed cells of the lattice structure, wherein the web connectors each have a connector axis extending between two cells which, in a longitudinal direction of the lattice structure, are adjacent to each other. During the transition of the lattice structure from the production state to a compressed state, the web connectors rotate in such a way that an angle between the connector axis and a longitudinal axis of the lattice structure changes, in particular increases, during the transition of the lattice structure from a completely expanded production state to a partially expanded intermediate state.

  • Patent number: 9233013
    Abstract: A stent having a tubular lattice structure includes lattice elements, webs (10), and cells (11) delimited by the lattice elements. The lattice structure is transferred into a compressed state having a relatively smaller cross-sectional diameter and into an expanded state having a relatively larger cross-sectional diameter. Flexible contact elements (12) are associated with the lattice elements. The contact elements are adapted for transferring radial forces onto a vessel wall (20) and extending on the outer circumference of the lattice structure substantially in the longitudinal direction of each associated lattice element. The contact elements (12) are wider in each case than the associated lattice elements, at least in sections.

  • Publication number: 20150366687
    Abstract: Medical device having compressible and expandable, circular cylindrical lattice structure, which includes circumferential segments having closed cells. The cells are bounded by four respective webs, which are coupled to each other and every two oppositely arranged webs to form a web pair. The webs of a first pair have a different shape and/or a web width at least in some sections than the webs of a second pair. The webs of the first pair can be deformed more greatly than the webs of the second pair. During the transition of the lattice structure from the expanded to the compressed state, each web of the first pair is coupled to a respective web of the second pair in such a way that two connection points oppositely arranged in the longitudinal direction (LR) of the lattice structures are moved away from each other in the circumferential direction (UR) of the lattice structure.
