From 10th to 16th of June the Polish National Free Diving team, sponsored by Grena, is attending The 2022 CMAS World Freediving Indoor Championship in Belgrade, Serbia. This team is an exceptional group of fantastic and talented people. We are proud to be a part of their path and without a doubt this year we are absolutely confident they will bring home another set of medals.
Dear Partners
The long awaited, dedicated laparoscopic applicators for our 4SEAL® Hemostatic Powder are finally available!
Dear Partners
The introduction of our the XXL size of Click'aV PLUS line was one of the most important events for Grena in 2021.
The comprehensive scientific program included live laparoscopic, robotic and endourological surgeries performed by prominent urologic surgeons. One of the goals of the conference was to emphasize the importance of recognition of women surgeons by all organizations involved in surgery.
WHY 4SEAL®? Because is the simplest and most straightforward product of the hemostatic market with the strongest hemostatic and anti-adhesion potential at the same time!
