Financial support and sponsorship
We are grateful for the financial support by the Heidelberger Stiftung Chirurgie (grants 2016/ 22, 2017/ 171,
2018/ 215, 2019/ 288, 2020/ 376, and 2021/ 444).

Conflicts of interest
FK received financial and material support by Baxter, Becton Dickinson, Corza Medical,
Dahlhausen, Ethicon, FEG, GEM, Medtronic, Olympus and pfm medical based on a Third-Party-Funding-
Agreement with the Heidelberg University and / or with Asklepios proresearch. The other authors declare
no conflict of interest.

Ethical approval and consent to participate
The research was conducted after building a bench test for low cyclic loading of tissues. Human material
was not used. Accordingly, no informed consent from patients was required. The ethical approval to use
animal tissues was given by local authorities according to European law with the permission DE 08 221
1018. Figure 2 requires courtesy of Samuel Voss, who provided the pictures. The studies for computed
tomography at rest and during the Valsalva maneuver were reviewed and approved by the Ethics
Committee of the Heidelberg University vote S-522/2020.

Consent for publication
Not applicable.
