Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding

Advanced Intelligent Systems, EarlyView.
Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Tips and Tricks for Hardware Removal and Allograft Fixation After a Failed Latarjet Procedure

Arthroscopy Techniques, EarlyView.
Abstract Although relatively rare, recurrent anterior shoulder instability requiring revision surgery after a failed Latarjet procedure can result in complications such as graft malposition, graft osteolysis, broken hardware and/or infection. Revision surgery after a failed Latarjet is a challenge due to a combination of technical factors such as ...
