Abstract: The device for blood oxygenation includes a gas exchange chamber with passage openings. One side the chamber is connected in a gas-tight manner with the expansion tank feeding the gas mixture containing oxygen to the chamber, having the inlet opening of gas mixture from the feeding installation. The other side of the chamber is connected in a gas-tight manner with the gas mixture discharging tank, having the outlet opening of gas mixture. The inner part of the chamber has a membrane as a capillary bundle permeable to gas mixture particles and non-permeable to blood particles, ends of which are anchored in the passage openings. The capillary bundle is tensed with a tension force and is parallel to the longitudinal axis of the chamber and to each other, or are arranged spirally. The side wall of the chamber has at least one inlet/outlet opening.

Abstract: A biological low profile balloon expandable prosthetic heart valve, particularly aortic for transcatheter implantation comprising a valve frame of cylindrical design which consists of a valve section, a supporting section and a biological material sewn thereto. The upper part of the cylindrical cuff made of the biological material is attached to the valve frame in the supporting section on the outside and the cuff is folded to the interior of the frame and it is attached to the posts in the valve section. The upper parts of the cuff which are not attached to the posts, on each side of the post are connected with each other on the valve frame establishing commissures for the valve leaflets.

Abstract: A delivery system for implants used in structural heart diseases by a minimally invasive method comprises a catheter (2) which is connected with the distal section of the balloon (1) and on the other side with the straight cap with the lateral canal (10) to which a pressure syringe for pumping the balloon is attached. The catheter is covered from the outside with a special shield (8). The balloon (1) has a necking in the middle section and inside the balloon and in the catheter (8) there is a canal (6) led outside the balloon formed at the end in the shape of a coil (3). Inside the balloon (1) or outside it at its distal and proximal ends the system is equipped with at least one anchoring mechanism shapely formed crimped on the balloon surface of the implant preventing its uncontrolled moving.

Abstract: A method of forming prefabricated units used in production of systems of prosthetic aortic valve transcatheter implantation and prosthetic aortic valve prefabricated unit with an non-thrombogenic smooth surface layer or with a porous fibrous layer constituting a scaffold for epithelium cell culture, intended for manufacturing TAVI system. Stents for covering and solutions of polycarbonate silicones and/or polycarbonate urethanes and/or polyurethane with average molecular weight in the range from 50 000 g/mol to 200 000 g/mol in the solvent DMAC are prepared. Initially a smooth layer of polycarbonate silicone is applied in the electrospinning machine by electrospraying with use of the solution in DMAC with the concentration of 2-8% w/w.

Abstract: A low profile balloon expandable artificial prosthetic heart valve, particularly aortic, for transcatheter implantation comprises a valve frame of cylindrical structure. The cuff made of the polymer material is inseparably integrated with the frame so that the valve frame in the supporting section is embedded or sewn into and covered from the internal side and from the outside with the cuff material, which folded into the interior section of the frame and in the frame valve section is formed into valve leaflets in bicuspid or tricuspid configuration and in the said section it is attached to the frame and to the frame posts, and the cuff material excess is led into the longitudinal openings in the posts.
