The founder and owner of the company, Assoc. Prof. Karel Volenec, PhD., worked until 1986 at the Institute of Experimental and Clinical Radiobiology and the Use of Radioisotopes of the Medical Faculty of Charles University in Hradec Králové, where he dealt with new methods of cancer treatment. However, it was not possible to put the results of the work into practice at the faculty. Therefore, Karel Volenec decided to start a business and, from his own resources, founded the company ELLA-CS.


Today, our unique products help thousands of patients every year and gain recognition around the world. More than 90% of our production goes to over 70 foreign countries around the world and territories of our activities are constantly expanding. We currently own a number of Czech and international patents and have gained the respect of the competition for the world's unique biodegradable reinforcement, which helps to free the passage of the digestive tract and is now commonly mentioned in the medical literature in Europe and the USA.
