Stent for the transluminal implantation in hollow organs
First Claim
1. A stent for transluminal implantation in hollow organs including blood vessels, ureters, oesophagae and gall tracts, the stent comprising:
- a body having a substantially tubular wall with a longitudinal axis extending therethrough, the wall having a compressed state with a first cross-sectional diameter and an expanded state with a second cross-sectional diameter larger than the first cross-sectional diameter;
apertures of the body spaced in a longitudinal direction along the tubular wall and in a circumferential direction around the tubular wall for permitting the wall to expand from the compressed state to the expanded state, the apertures forming slot openings in the wall in the compressed state; and
sections of the slot openings with each slot opening having a plurality of sections that extend obliquely relative to the longitudinal axis.

Abstract
A stent for transluminal implantation in hollow organs, in particular in blood vessels, ureters, oesophagae or gall tracts, comprising a substantially tubular body is described. The stent can be transformed from a compressed state with a first cross-sectional diameter into an expanded state with a second enlarged cross-sectional diameter. The wall of the tubular body has apertures which repeat both in the longitudinal direction and also in the peripheral direction of the stent and permit the expansion. Each aperture has at least one section which is arranged obliquely to the longitudinal axis of the stent, both in the compressed state and also in the expanded state of the stent.
