Abstract
Cilj diplomske naloge je ugotoviti verjetnost brezhibnega delovanja nekaterih pogosto uporabljenih medicinskih vsadkov. Izbrani sta bili dve vrsti vsadkov, in sicer srčni spodbujevalnik ter polžev vsadek. Za osvetlitev problematike rizičnosti naprav so v nalogi opisani koncepti električne stimulacije z različnimi metodami. Navedene so stimulacijske metode in tehnološke izvedbe naprav, ki so danes na voljo pri obeh vrstah obravnavanih naprav. Specifika srčnih spodbujevalnikov je, da sta v praksi in v tem diplomskem delu ločeno obravnavana spodbujevalnik in elektrode, ki služijo za dovajanje električnega stimulusa na steno srčne mišice. Polžev vsadek je obravnavan kot enota, ki ima svoj notranji del, ki je namenjen vgradnji, in zunanjo enoto, ki služi za digitalno obdelavo in prenos zvočnih signalov preko radiofrekvenčne povezave na notranjo enoto. Obe vrsti vsadkov predstavljata tveganje za uporabnika zaradi biokompatibilnosti in morebitnih okužb. Verjetnost brezhibnega delovanja naprav, ki je pogojena s tehnološko izvedbo, analiziramo na podlagi pridobljenih podatkov skladno z metodo, ki jo uporabljajo proizvajalci srčnih spodbujevalnikov in polževih vsadkov.

Title:Operational principles and reliability of active medical implants
Abstract:
Aim of this thesis is to define the performance reliability of often used medical implants. Two types of implants were chosen, namely a pacemaker and cochlear implant. Rudiments of electric stimulation are described to illuminate the problem of hazard devices, which are using different stimulation methods. Stimulation methods and technological performance of devices that are available today are listed for both types of implants. Pacemaker specifics are, in practice and in this thesis examined separately. Pacemaker as a unit and electrodes, which serve to supply heart muscle with electrical stimuli. Cochlear implant is treated as a device with its internal unit, which is intended to be implanted, and an external unit, which is used for digital processing and transmission of signals via a radiofrequency link to the internal unit. Both types of implants represent a risk to the user due to the biocompatibility and possible infections. The performance reliability, which is conditioned by technological implementation, was analysed on the basis of acquired data in accordance with method used by manufacturers of pacemakers and cochlear implants.

Keywords:medical implants, pacemaker, cochlear implant, performance reliability
