Questions? I'd be happy to answer them!


The Gripper® (MedEnvision) is a patented instrument developed by Prof. Dr. Corten.

The Gripper® is placed on the wound retractor. An optimal, muscle-sparing wound retractor is very important to allow the surgeon to have a good view of the incision so that the prosthetic components can be placed perfectly.


The EsySuit® (MedEnvision), co-developed by Prof. Dr. Corten, is an ingenious sterile suit that is put on in one smooth motion in less than one minute. This in contrast to the normal procedure which requires much more action. This patented suit was developed for the EDA Hip, but is now used by many hip surgeons.
