Assessment of metallic patient support devices and other items at 7-Tesla: Findings applied to 46 additional devices.

Recently, the first 7-Tesla MR system was approved for clinical use in Europe and the United States. Unfortunately, few metallic objects have undergone testing in association with this high-field-strength scanner, including essential equipment such as patient support devices and other items. Therefore, the objective of this investigation was to assess metallic patient support devices and other items for translational attraction at 7-Tesla.

Cardiac rhythm management devices

The last decade has seen ongoing evolution and use of cardiac rhythm management devices, including pacemakers, cardiac resynchronisation therapy, implantable cardioverter defibrillators and loop recorders. General practitioners are increasingly involved in follow-up and management of patients with these devices.

The regulatory ancestral network of surgical meshes.

All surgical meshes entering the U.S. market have been cleared for clinical use by the 510(k) process of the Food and Drug Administration (FDA), in which devices simply require proof of "substantial equivalence" to predicate devices, without the need for clinical trials. However, recalled meshes associated with adverse effects may, indirectly, continue to serve as predicates for new devices raising concerns over the safety of the 510(k) route.

Standards for testing and clinical validation of seizure detection devices.

To increase the quality of studies on seizure detection devices, we propose standards for testing and clinical validation of such devices. We identified 4 key features that are important for studies on seizure detection devices: subjects, recordings, data analysis and alarms, and reference standard. For each of these features, we list the specific aspects that need to be addressed in the studies, and depending on these, studies are classified into 5 phases (0-4). We propose a set of outcome measures that ne...

Imaging features of leadless cardiovascular devices.

E-cigarette devices used by high-school youth.

Background E-cigarette use rates are high among youth, but there is limited information on the types of e-cigarette devices that are used by youth. Methods During Spring 2017, students from 4 high schools completed surveys on use of e-cigarette devices (cig-a-like, vape/hookah pen, modified devices or mods, and JUUL). Among youth who endorsed ever (lifetime) use of an e-cigarette and of at least one device (n = 875), we assessed 1) prevalence rates of ever and current (past-month) use of each device, 2)...

Use of iontophoresis for the treatment of cancer.

Despite major advancements in cancer treatments, there are still many limitations to therapy including off-target effects, drug resistance, and control of cancer-related symptoms. There are opportunities for local drug delivery devices to intervene at various stages of cancer to provide curative and palliative benefit. Iontophoretic devices that deliver drugs locally to a region of interest have been adapted for the treatment of cancer. These devices have shown promise in pre-clinical and clinical studies f...

Comparison of orofacial thermal sensitivity assessed with simple devices and sophisticated equipment.

Simple thermal devices providing reliable data are needed to detect somatosensory disturbances in non-specialized clinical settings. Currently, evidence is lacking about their use. Therefore, the aim was to compare the assessment of perceived thermal sensitivity/pain in healthy humans with a state-of-the-art thermotester and with simple inexpensive customized thermal aluminum devices.

Optical Care in Low Vision Patients.

The numbers of low vision patients will steadily increase because of increasing longevity. It is important to be aware of those patients so that visual rehabilitation can be started as soon as possible and needed. Before the adjustment of low vision devices a diagnosis should be confirmed in order to check any therapeutic option and to ensure the best individual rehabilitation. If there is no further therapeutic option left a detailed anamnesis of the problems due to low vision should be made to ensure that...

Tackling the concept of symbiotic implantable medical devices with nanobiotechnologies.

This review takes an approach to implanted medical devices that considers whether the intention of the implanted device is to have any communication of energy or materials with the body. The first part describes some specific examples of 3 different classes of implants, analysed with regards to the type of signal sent to cells. Through several examples, we describe that a one way signalling to the body leads to encapsulation or degradation. In most cases, those phenomena do not lead to major problems. Howev...

Significant cephalad lead migration with use of externally powered spinal cord stimulator.

Spinal cord stimulation has been an effective therapy for treatment of chronic low back pain over the last four decades. Over the years, there have been significant technological advances in the neuromodulation devices. Externally powered neuromodulation devices, that do not require an internal pulse generator (IPG) implantation, have recently been approved for treatment of chronic pain and the data on potential pitfalls and unforeseen complications with these devices is minimal. Here, we report a case of a...

In vitro comparison of the hemocompatibility of two centrifugal left ventricular assist devices.

Shear stress from left ventricular assist devices induces von Willebrand factor degradation and platelet dysfunction, leading to nonsurgical bleeding.

Ray-optical transformation optics with ideal thin lenses makes omnidirectional lenses.

We present the theory of ray-optical transformation optics (RTO) with ideal thin lenses and show that ideal-thin-lens RTO devices are omnidirectional lenses. Key to designing such devices are two theorems, the loop-imaging theorem, and the edge-imaging theorem, which ensure that the interior physical space is distorted in the same way for all viewing directions. We discuss the possibility of realising such devices using lens holograms or Fresnel lenses, as both are in principle capable of changing the direc...

Common Principles of Molecular Electronics and Nanoscale Electrochemistry.

The merging of nanoscale electronics and electrochemistry can potentially modernize the way electronic devices are currently engineered or constructed.
