Vascular stents - materials and manufacturing technologies
PublicationThe objective of this article is to present materials and technology for the manufacture of vascular stents with appropriate design requirements. The use of the right material is very important in implantology. A biomaterial introduced into the circulatory system must be biocompatible and hemocompatible. At the same time, it should not initiate toxic, mutagenic, or immunological reactions. Currently, 316L stainless steel (316L...

BIOMATERIALS AND IMPLANTS IN CARDIAC AND VASCULAR SURGERY - REVIEW
PublicationCurrently, on prosthesis in cardiac blood vessels and heart valves are used materials of animal or synthetic origin. For animal materials include, among others pericardial sac in which is the heart. Materials such as this (natural) are characterized by a remarkable biocompatibility within the human body, but their main disadvantage is the relatively low durability. In turn, synthetic materials, which include the austenitic chromium-nickel-molybdenum...

Timed rolling and rising tests in Duchenne muscular dystrophy ambulant boys: a feasibility study
PublicationBACKGROUND: Functional activities are extensively used in motor assessments of patients with Duchenne muscular dystrophy. The role of timed items has been reported as an early prognostic factor for disease progression. However, there are two functional activities that are not widely assessed in clinical practice among Duchenne muscular dystrophy patients: rolling and bed rising. This study aimed to investigate whether the 360-degree...

Effect of Vascular Lumen Reduction on the Performance and Energy Consumption of an Innovative Implantable LVAD
PublicationThis paper presents the results of a study on the effect of vascular lumen reduction on the performance of an innovative implantable LVAD (left ventricular assist device). It details the pressures in the individual cardiac chambers as a function of device frequency. In addition, mass flow rates and energy consumption of the device are examined, varying with lumen reduction and operating frequency. While the lumen reduction of the...

Application of Intuitionistic Fuzzy Sets to the assessment of technical university students
PublicationThe article proposes application of artificial intelligence methods to assess students of technical universities. The level of achieved educational goals can be assessed using measurements based on the idea of Fuzzy Intuitionistic Sets (IFS). A classification algorithm was developed and an exemplary distribution of the criteria values using IFS was presented. The application of the proposed approach in online education can enrich...

Evaluating architecture students' knowledge of the history of architecture by tests and by drawings: a comparative analysis
PublicationThe methods of evaluating students’ knowledge in architectural education, and in particular in education on history of architecture, are specific in many respects. Apart from checking the general knowledge of history concerning chronology, artistic trends, styles, main objects and architects, it should also check students’ ability to analyse the historic architecture in a drawing form. Such a form of presenting architecture has...

Developing Materials for Biodegradable Otolaryngological Stents
PublicationMaterials for otolaryngological stents have to be characterized by good tensile strength, wear resistance, biocompatibility, and specific degradation time. This work aimed to synthesize polyurethanes based on various biodegradable polyol blends. Their biodegradability and mechanical properties were tested and compared to commercial BIOFLEX material.

Antimicrobial and Antiproliferative Coatings for Stents in Veterinary Medicine—State of the Art and Perspectives
PublicationMicrobial colonization in veterinary stents poses a significant and concerning issue in veterinary medicine. Over time, these pathogens, particularly bacteria, can colonize the stent surfaces, leading to various complications. Two weeks following the stent insertion procedure, the colonization becomes observable, with the aggressiveness of bacterial growth directly correlating with the duration of stent placement. Such microbial...

Effects of stents under asymmetric inflow conditions
PublicationW publikacji rozważano komputerowe modele stentów przy niesymetrycznych warunkach napływu i ich wpływ na naprężenia styczne na ściankach. Umożliwia to znajdowanie kształtów stentów, które są mniej wrażliwe na brak symetrii napływu. Zmiany kształtów arterii można wiązać ze zmianami charakterystyki przepływów takimi jak m.in. naprężenia styczne na ściankach, które zwiększają ryzyko restenozy. Posłużono się również pojęciem dyssypacji...
