In June 2018, I had the great pleasure to take part in a course organized by RRSSC and Primetech on the implantation of iPrecio mini pumps into the blood vessels of mice and rats. Thanks to Rene’s valuable tips and perfectly organized training, I have almost immediately performed the procedure of the jugular and femoral vein catheterization in mice and rats. Something that previously seemed to be impossible for me. With the help of René, it took around 20 minutes to get the catheter into the vessel of choice. René is a very hospitable man with a passion for science and I admire and appreciate his great knowledge. He can talk about animals, their anatomy, and pharmacology so that the listener can not get away from the lecture. I definitely recommend everyone to come to Almere and take part in one of these rodent training courses.
