We used a technique of electrode positioning differing from the transpalpebral ROG technique used previously. Specifically, we changed the distance between the measuring electrodes and their location pattern: the axis of symmetry was rotated 90° relative to that used in the transpalpebral technique and located vertically rather than horizontally. This technique was applied to ROG signals of 32 patients (42 eyes) aged 67.7 years averagely. Of these, 6 patients (10 eyes) average aged 62.7 years had stage I (early) POAG or suspected POAG; 13 patients (17 eyes) average aged 69.4 years had stage II (developed) POAG; 10 patients (12 eyes) average aged 70.0 years had stage III (advanced) POAG; 3 patients (3 eyes) average aged 69.3 years had stage IV (terminal) POAG. The results of this study confirmed the feasibility of the above technique for ROG signal registration. The recorded signals are informative for quantitative assessment of blood flow in the posterior part of the eye, which enables early POAG diagnostics and differentiation between POAG stages.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124169435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are under high constraints, both economic and regulatory, but also in terms of quality and safety requirements. The new European regulation comes in addition and questions all of the actors of the maturation process from the idea-to-market for medical devices (MDs). The objective of this qualitative study was to collect and analyze feedback from various European stakeholders involved in the clinical evaluation of medical devices, with a special focus on innovative high-risk medical devices. This paper presents the results of the first phase which scope was limited to France with sixteen interviews. Results show the complexity of the clinical evaluation of MD, particularly when dealing with an innovative, high-risk medical device. The need for training and support of actors through specialized platforms was highlighted, as well as the need for coordination between public and private actors, from the upstream phases of R&D. The collection of clinical data must be part of an overall strategy considering the maturation cycle of the product and its different dimensions. The collection of real-life data must be amplified and structured, with the contribution of new digital technologies opening up new fields of research. This approach must be strengthened by (i) the development of methods based on choices justification, and (ii) making it possible to capitalize on and crossreference data on the Medical Device throughout its life span. The brief overview provides convergent conclusions, but the understanding of the required level for the evaluation of medical devices and of the way to reach it was not uniform. This reflects a heterogeneous sector and it introduces the need of compromises regarding development strategies and methodological approaches.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126019716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, hemodynamic covariates may also contribute to BP values. Our previous study has proposed a BP model based on PTT, HR, stiffness index (SIx) and descent time (DT), which has been validated on the Multiparameter Intelligent Monitoring for Intensive Care (MIMIC) database. In this article, we present a prototype cuff-less monitoring device for non-invasive estimation of BP, which can obtain both electrocardiogram (ECG) and finger plethysmograph (PPG) signals synchronously. The model proposed above has been validated by using ECG and PPG records from 22 healthy subjects with no cardiovascular disease and hypertension, and the error of BP estimation was 0.002±8.544 mmHg for SBP, 0.005±6.690 mmHg for DBP. The reliability of this method in long-term BP monitoring was further verified by studying the data of one individual for 28 days, while the error was 5.204±5.462 mmHg for SBP, 2.714±4.756 mmHg for DBP without calibration. The results show that the model could estimate the BP value within the acceptable error range based on this study, which is extremely close to AAMI's standard (5±8mmHg) and consistent with the cuff-method. The proposed ultra-low power, wearable, time-synchronized prototype monitoring device with an embedded hemodynamic covariate model, can measure SBP and DBP values accurately, which is expected to estimate continuous blood pressure better.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116678210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sometimes pathological phenomena lead to abnormal hypertrophic or keloid scars, with evolutions varying depending on different conditions: origin of the tissue barrier disruption, concerned body area, or ethnic origin. Based on these statements, care procedures have been developed to avoid aesthetical or functional impairments: drugs injection, surgery, cryotherapy or mechanical compression. The story will relate the matching of a multi-disciplinary team that focused on covering an unmet need for ear lobe keloid treatment, providing patients an optimal and holistic care. The benefits researched lied in improving the understanding of the disorder, avoiding the recidivism of the scars, diminishing the frequency and duration of care, and in end improving patients’ quality of life. The paper will not only narrate the building of a health innovation, on technological, clinical, user points of view, but will also try to detail the evaluations planned at the different stages of development, as well as the challenges, conditions and prerequisites allowing to produce concrete solution.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130275988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following the previous work, which established the materials to be used, according to the wetting properties and their influence on the dynamic response of the droplets (which are electrostatically actuated) this paper presents the final simulations to optimize the thickness and material of the dielectric coating, always as a function of the dynamic response of the droplets. Then, to avoid contamination issues, a number of analogue fluids are proposed, in a new approach, which are characterized and tested in the second part of the work. Regarding the characterization of these new fluids, preliminary results suggest a great potential of a surfactant solution to be used as an analogue. The addition of the surfactant results in the formation of semirigid particles with a size distribution and deformation characteristics compatible with those of the biosamples to be studied. The surfactant solution also shows a swift response to electrostatic actuation.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"57 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124478841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
