Transcatheter bicuspid venous valve prostheses: fluid mechanical performance testing of artificial nonwoven leaflets.

Background: Chronic venous insufficiency (CVI) is a common disease with a high prevalence. Incompetent venous valves are considered as one of the main causes. Besides compression therapy, various surgical therapies are practiced, whereby the reconstruction of valves is of central importance.

Investigation of Stent Prototypes for the Eustachian Tube in Human Donor Bodies.

Chronic otitis media is often connected to Eustachian tube dysfunction. As successful treatment cannot be guaranteed with the currently available options, the aim is to develop a stent for the Eustachian tube (ET). Over the course of this development, different prototypes were generated and tested in ex vivo experiments.
