Analysis of biotribological properties of artificial hip joint
Laštůvka, Jan ; Burša, Jiří (referee) ; Návrat, Tomáš (advisor)
The development of total hip arthroplasty has reached a state when quality prostheses are made, whose longevity is influenced significantly by material properties, design, component fixation and rate of wear of the articulating surfaces. It is the wear rate which is the most important factor influencing successful results for the use of total hip prostheses. The aim of this thesis is to perform a research on the various combinations of hip prostheses and its loading conditions. Also an experimental measurements of Bovine serum lubricating film thickness between the artificial femoral head and a glass disc are performed for different contact kinematic conditions.

Contribution of technical equipments to treatment of blood vessel diseases
Laštůvka, Jan ; Návrat, Tomáš (referee) ; Burša, Jiří (advisor)
The goal of this bachelor’s thesis is an introduction to the anatomy and pathology of vascular system and providing an overview of technical equipment used for examination and treatment of blood vessel diseases. Using two type of blood vessel implants it illustrates the process of computation during the phase of creating a concept. In the former case the influence on blood flow and healthy blood vessel behaviour when using bifurcated blood vessel prosthesis is assessed, in the latter case the projecting computation of biflex stent construction is examined.
