Item type:Publication, Access status: with files , Design of personalized devices—the tradeoff between individual value and personalization workload(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-01); ; ; ; Personalized medical devices adapted to the anatomy of the individual promise greater treatment success for patients, thus increasing the individual value of the product. In order to cater to individual adaptations, however, medical device companies need to be able to handle a wide range of internal processes and components. These are here referred to collectively as the personalization workload. Consequently, support is required in order to evaluate how best to target product personalization. Since the approaches presented in the literature are not able to sufficiently meet this demand, this paper introduces a new method that can be used to define an appropriate variety level for a product family taking into account standardized, variant, and personalized attributes. The new method enables the identification and evaluation of personalizable attributes within an existing product family. The method is based on established steps and tools from the field of variant-oriented product design, and is applied using a flow diverter—an implant for the treatment of aneurysm diseases—as an example product. The personalization relevance and adaptation workload for the product characteristics that constitute the differentiating product properties were analyzed and compared in order to determine a tradeoff between customer value and personalization workload. This will consequently help companies to employ targeted, deliberate personalization when designing their product families by enabling them to factor variety-induced complexity and customer value into their thinking at an early stage, thus allowing them to critically evaluate a personalization project.Publicationtype: Journal ArticleScopus© Citations 11 206 257 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Qualification of additively manufactured blood vessel models for the evaluation of braided stent designsFor testing new designs of braided stents, an animal free anatomical model is needed, in which different Flow Diverter (FD) designs can be implanted and evaluated. The geometric replication of vessels by additively manufactured (AM) models has already been proven for aneurysm coiling within the neurointerventional training model HANNES. Nevertheless, since FDs closely interact with the vessel wall, AM vessel model materials need to be qualificated for the use case. Therefore, this paper presents an appropriate test bench for AM material tests and characterizes AM impact factors. As an outlook, different AM materials are tested and compared. Additionally, the impact of the postprocessing is investigated for one material. The paper shows the qualification of AM models for animal free design tests of a medical devices, where an objective test environment gives the opportunity to qualify AM materials for the medical use case.Publicationtype: Conference Paper106
