MEDICAL DEVICE FOR INSERTING INTO A HOLLOW ORGAN OF THE BODY

摘要

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.

1. A medical device for inserting into a hollow organ of the body, the medical device comprising:
a lattice structure comprises an expanded state, a compressed state, and an intermediate state, the intermediate state being between the expanded state and the compressed state; the lattice structure having a longitudinal axis defining a longitudinal direction; the lattice structure comprising a plurality of webs and a plurality of closed cells, each web of the plurality of webs bounding one cell of the plurality of closed cells; and a plurality of web connectors, each web connector integrally connecting a first web of the plurality of webs to a second web of the plurality of webs, each web connector having a connector axis extending between a first cell and a second cell of the plurality of cells, the first cell and the second cell are adjacent in the longitudinal direction; wherein when the lattice structure is in the expanded state, the connector axis and the longitudinal axis are offset from each other by a first angle; and wherein when the lattice structure is in the intermediate state, the connector axis and the longitudinal axis are offset from each other by a second angle; the second angle being larger than the first angle.
