Description

technical field

[0001] The invention relates to a membrane implant for the treatment of vascular malformations, said implant consisting of an expandable stent and a membrane connected to said stent, wherein said membrane covers the mesh of said stent at least in the central region. The membrane implant is intended to be implanted intravascularly in the vascular system of the patient to be treated. Background technique

[0002] For the treatment of vascular malformations, in particular of arteries, usually confined to a small area, a number of devices have been developed which apply purely or preferentially local effects of mechanical, thermal, chemical, electrical or pharmaceutical nature. These treatment methods are mainly based on endovascular techniques, by means of which the treatment device is guided via a catheter to the placement site and applied there.

[0003] A common form of treatment, especially in conjunction with sclerotic narrowing of blood vessels, but also ...
