Evaluation of three polymer materials for the production of embryo transfer catheter for pigs

The research aimed to improve laparoscopic methods of embryo transfer in pigs and implement new biomaterials with high biocompatibility and desired material characteristics for reproduction. The possibility of using biometrics used in the medicine of polypropylene (PP), polyethylene (PE), and polylactide (PLA) was investigated. In the first stage, material tests were carried out, determining the functional properties of the materials and the possibility of forming tubes with the desired mechanical properties (strength and flexibility), geometry (length, thickness, and shape constancy), and surface structure. In the second stage, the functional features and biocompatibility of the materials were confirmed by the recipients. Of the materials tested, only the PE catheters had functional and biological properties. An efficient method of laparoscopic embryo transfer in pigs has been developed using the developed PE catheter.
