ReviewVisions on the future of medical devices in spinal cord stimulation: what medical device is needed?
Recently burst stimulation and 10 kHz stimulation have been developed as novel stimulation designs. Both appear to be superior to classical tonic stimulation in the amount of responders and the amount of pain suppression and have as an extra advantage that they are paresthesia-free. ⋯ This evolution mandates a new approach in the development of internal pulse generators, and the most obvious approach is to develop an upgradable stimulator, on which new stimulation designs can be downloaded, analogous to the apps people download on their smartphones. This will create a shift from hardware driven products to software driven stimulators.

ReviewUpdate on the use of abdominal and thoracic endografts for treating aortic aneurysms.
Endovascular abdominal and thoracic aneurysm repair has heralded a paradigm shift in the management of abdominal and thoracic aortic aneurysms. Randomized controlled trials have suggested superior short-term and equivalent long-term outcomes of endovascular repair compared with open surgery. ⋯ The advent of fenestrated and branched endografts have made endovascular repair of thoracoabdominal and juxtarenal aneurysms possible. Continued evolution of endograft technology will maximize the benefit and minimize complications in patients with a range of aneurysmal disease.

ReviewFrom drug eluting stents to bioresorbable scaffolds; to new horizons in PCI.
Drug eluting stents and particularly the fully bioresorbable drug-eluting scaffolds herald a new era in percutaneous treatment of coronary artery disease. There has been tremendous progress in drug eluting stents with fully biodegradable coating polymers and polymer-free devices with reservoir technology planting the anti-proliferative drug. ⋯ Enhanced mechanical flexibility that provides superior conformability to the vessel wall, resumption of the vasoreactivity in the follow-up period and improving visualization on non-invasive imaging modalities are some of the supremacies of the fully bioresorbable scaffolds. In this review, we aim to give a general view on the latest developments in metallic drug eluting stents and fully bioresorbable scaffolds.

ReviewTechnology platforms for remote monitoring of vital signs in the new era of telemedicine.
Driven by healthcare cost and home healthcare need, the development of remote monitoring technologies is poised to improve and revolutionize healthcare delivery and accessibility. This paper reviews the recent progress in the field of remote monitoring technologies that may have the potential to become the basic platforms for telemedicine. In particular, key techniques and devices for monitoring cardiorespiratory activity, blood pressure and blood glucose concentration are summarized and discussed. In addition, the US FDA approved remote vital signs monitoring devices currently available on the market are presented.

ReviewAdvanced waveforms and frequency with spinal cord stimulation: burst and high-frequency energy delivery.
In recent years, software development has been key to the next generation of neuromodulation devices. In this review, we will describe the new strategies for electrical waveform delivery for spinal cord stimulation. A systematic literature review was performed using bibliographic databases, limited to the English language and human data, between 2010 and 2014. ⋯ High-frequency and burst stimulation may offer advantages over tonic stimulation, as data suggest improved patient tolerance, comparable increase in function and possible success with a subset of patients refractory to tonic spinal cord stimulation. High-frequency and burst stimulation are new ways to deliver energy to the spinal cord that may offer advantages over tonic stimulation. These may offer new salvage strategies to mitigate spinal cord stimulation failure and improve cost-effectiveness by reducing explant rate.
