VueTek has developed a head mounted device that will improve the viewing of superficial, subcutaneous vasculature, differentiating it with higher contrast from surrounding tissue. Video of the vasculature is displayed to the user in a portable headset. The headset and display combination facilitates both visualization in the display and an open field of view directly to the subject's anatomy and practitioner's surroundings. The goal is to provide a non-diagnostic, enhanced visu...
Coloscopy may be a painful procedure for the patient. This is due to a loop-formation of the coloscope. A 3D-real time imager produced by Olympus creates a real-time image of the scope while a traditional fluoroscopy device will only show instant pictures. We want to investigate whether the 3D-imager causes the patient less pain and is more time consuming than ordinary fluoroscopy

The goal is to confirm the pre-clinically demonstrated technical accuracy and safety of the newly developed MR-Linac in the clinical setting.
Percutaneous transluminal angioplasty (PTA) of infra-popliteal arteries in patients suffering peripheral arterial occlusive disease (PAOD) provides good results in terms of limb salvage. During the last decade, drug eluting balloons (DEB) were found to be an effective tool for the treatment of atherosclerotic disease in several arterial districts. Aim of this study is to compare results of DEB PTA versus standard PTA of infra-popliteal district in patients with CLI, from a sing...
We are developing Blood Pressure Imager (BPI), which is a new technology that does not require cuffs or expensive equipment, and can be used by untrained individuals in underserved, low-resource environments at their own homes or regional care settings. Over the last one-year we have developed the BPI prototype, which is ready for testing. BPI is a wrist device that includes a camera, LED lights and soft membrane with a reflective coating. In this device feasibility study, the ...
this study will be undertaken to evaluate the safety and analgesic efficacy of adding ketamine to bupivacaine in bilateral infra-orbital nerve block for relief of pain postoperatively following repair of cleft lip in children less than two years of age.
To collect both pre-market and post-market confirmatory evidence of the safety and effectiveness of the LifeStent Self-Expanding Stent System in patients with de novo and restenotic (non-stented) lesion(s) in the infra-inguinal (SFA and Popliteal) arteries.
In this study the investigators plan to systematically characterise infra-slow EEG oscillations during sleep, explore their relationship to the microstructure of sleep, and investigate its role in the physiology and pathophysiology of sleep by co-registration of Full band EEG with polysomnography during wake and sleep in healthy subjects, after sleep deprivation, and in patients with restless legs syndrome/periodic leg movements during sleep (RLS/PLMS).
Not all infectious agents have the same epidemic potential, and this can vary widely within the same species. Rapid determination of this potential is essential to optimize control of infectious diseases. It is now accepted that identification with the species is clearly insufficient to identify an epidemic and to carry out epidemiological analyzes. Indeed, if the same bacterial species can present a great diversity of strains, it is organized in clonal complexes having strong ...
Currently, there are no tools that can measure nasal airflow in an objective manner that is non-invasive to the patient. This clinical study aims to address this by evaluating the use of thermal imaging as a diagnostic tool for measuring nasal airflow. Proper airflow cools the nasal airway as it passes--obstructions or narrowed airways hinder flow and results in elevated temperatures along the airway and nasal tissue. It is this elevation in temperature, or more specifically, ...
Currently available antiarrhythmic drugs for the treatment of atrial fibrillation (AF) have a limited efficacy and often cause long-term side effects. Pulmonary vein isolation is the therapy of choice in drug-refractory patients. Recent studies have shown that ablation have a greater efficacy in patients in whom AF is maintained hierarchically and after ablation of rotors. The non-invasive identification of specific mechanism of AF maintenance in each patient could allow the se...
Inadvertent puncture of an unintended object in a vascular access procedure is common and can lead to serious consequences. Inadvertent common carotid artery (CCA) puncture while targeting the internal jugular vein (IJV), for example, is reported to have an incidence of 2% - 8% and usually results in localized hematoma formation. The hematoma may enlarge rapidly if the patient is coagulopathic, or if a large puncture wound is produced by the introduction of the sheath itself in...
The main objective of this study is the demonstration of an increase of over 50% of the surface visible on ultrasound (mm2) of the axillary vein and subclavian vein in arm abduction (90 °) and external rotation (90 °) with respect to the surface of the subclavian vein along the arm body.
This study will included 20 children presenting with epilepsy with spasms. It aims to offer these children, non invasively and without supplementary examinations, a recording of local and cerebral hemodynamic changes concomitant with an electroencephalographic recording during epileptic episodes. This will be carried out by combining optical imaging using near infra-red spectroscopy (NIRS) with electroencephalography (EEG), in a simultaneous high-resolution (HR) recording. ...
Findings in neuroscientific research show that the environment one lives in has measurable effects on brain morphology and functioning. Human exposure to airborne infra- and ultrasound has been constantly increasing during the last decades. For instance, the European Renewable Energy Directive, established in 2009, lead to an increased use of wind turbines, generating infrasound. The EU Directive states that until 2020 a 20% of the EUs' total energy needs is to be generated wit...
There is no shared vision relating to integrity and quality of the conduit after the impact on the vein wall during vein harvesting. In this connection, the investigators studied the initial state of the venous conduit, interoperation damages of the vein and postoperative wound complications while using two methods of GSV harvesting.
anatomical landmarks on the body surface were used to insert central vein catheter. However, ultrasound technique is emerging as a new technique for vein catheterisation. For subclavian and femoral vein catheterisation, up to now, there is a lack of evidence of the superiority of one technique over the other.
Dry Eye Syndrome (DES) is a disease affects the production and stability of the tear film, leading to vision disturbances and a major decrease in quality of life. The most recommended treatment for moderate-severe DES today which failed conservative therapy with lubricating eye drops is topical Cyclosporine 0.05% (Restasis®). The Tear Film Imager (TFI) is a novel imaging modality designed for visualization of the individual tear film layers up to a resolution of 0.1 micromete...
Anticoagulant therapy is generally recommended for all patients presenting with acute symptomatic splanchnic vein thrombosis, starting with either low-molecular weight heparin (LMWH) or unfractionated heparin and continuing with the vitamin K antagonists in most patients. Rivaroxaban is approved for the treatment of deep vein thrombosis and pulmonary embolism, but no studies have assessed the safety of rivaroxaban in the setting of splanchnic vein thrombosis. We aim to collect ...
