Medicine ches expansion element, a method for manufacturing such an expansion element and occlusion catheter with such an expansion element

摘要

The invention relates to a medical expansion element with a hollow body (10), which is a function of a compressed state can be transferred in an expanded state, and two end portions (11, 12), which in the expanded state have a smaller cross-sectional diameter than a central portion (13) of the hollow body, which extends between the two end portions (11, 12) extends, wherein the hollow body is a fluid-tight, flexible, in particular elastic wall (14) comprising at least in the middle section (13) a wall thickness of not more than 30 µm. The present invention also relates to a method for manufacturing such an expansion element as well as an occlusion catheter with such an expansion element.
