2022: Market Entry

Startup CML AT Medical The Foundation for Infrastructure and Educational Programs has brought to the Russian market a printed implant of the shoulder joint with a modified surface. The FIOP announced this on July 11, 2022.

The implant, developed by a startup of the North-West Nanocenter together with SINTEL and senior researcher at the Research Institute of Oncology of the Tomsk Research Center Ilya Aniseney, is designed to treat patients with extensive defects in bone structures in the shoulder joint resulting from injury or cancer.

The results of the first ten operations showed a high degree of congruence of the product, convenience of use in the endoprosthesis process, as well as good functional results in the postoperative period. In June 2022, the companies submitted a joint application to Rospatent for registration of the invention.

The CML AT Medical team designed the product to create a specific type of shoulder joint oncoimplant with better anatomical and functional properties. The startup engineers segmented the patient's CT scans and designed the implant taking into account the anatomical characteristics of the patient, facilitating it through topological optimization.

It was necessary to create an implant that provides functional effectiveness of treatment. When designing the product, we had to solve a number of technical problems: ensuring the reliability of the structure, increasing the life, reducing the number of rejection of the prosthesis, reducing the weight of the product. As a result, we managed to design a light, reliable oncoimplant of the shoulder joint, taking into account the individual features of the patient's biomechanics, "said Yana Chekryzhova, executive director of the CML AT Medical startup.

The implant was manufactured using 3D printing from a biocompatible titanium alloy. The product is made in the form of a whole structure with special holes for fixing the corresponding muscles of the thoracic region and the shoulder joint. This solution stimulates the fusion of the patient's tissues with the implant structure and provides movement in the shoulder joint. Applying a bioactive coating to the endoprosthesis by the manufacturer of the product - the scientific and production company SINTEL - gave the product anti-inflammatory and anti-tumor properties.
