Design and characterization of an implantable system for shockfree cardiac rhythm control

A 3-Mode Wide Operational Range Reconfigurable Regulating Rectifier for Wireless Power Transfer

This article presents a novel wide operational range reconfigurable regulating rectifier for wireless power transfer. The proposed 1X/2X/3X rectifier achieves wide range voltage regulation without global loop control to minimize the area occupation. Compared with previous work, more working modes and greater magnification allow the proposed...

Design of a 3D-printed hand prosthesis featuring articulated bio-inspired fingers

Various upper-limb prostheses have been designed for 3D printing but only a few of them are based on bio-inspired design principles and many anatomical details are not typically incorporated even though 3D printing offers advantages that facilitate the application of such design principles. We therefore aimed to apply a bio-inspired approach...

Design of a novel multi-modal stimulation device for the treatment of tinnitus

Approximately 15-20% of theworld population is aected by tinnitus, a hearing condition associated with phantomsound perception. A large number of suerers experience a severe level of tinnitus and they are not ableto conduct a normal life because they develop insomnia, depression, and distress.Extensive research has been made to study its...

Design and Evaluation of a Novel Endovascular Chordae Tendineae Repair Device

Currently, mitral valve regurgitation (MR) is one of the leading heart valve diseases with as much as 19% of men and women having at least mild MR and 1.9 % having at least moderate MR Singh et al. (1999). DEMCON Medical Systems is working on a novel TC method to repair Mitral valve regurgitation in early stages as a preventive measure against...

Catheter steering in interventional cardiology: Mechanical analysis and novel solution

In recent years, steerable catheters have been developed to combat the effects of the dynamic cardiac environment. Mechanically actuated steerable catheters appear the most in the clinical setting; however, they are bound to a number of mechanical limitations. The aim of this research is to gain insight in these limitations and use this...

Functional evaluation of a non-assembly 3D-printed hand prosthesis

In developing countries, the access of amputees to prosthetic devices is very limited. In a way to increase accessibility of prosthetic hands, we have recently developed a new approach for the design and 3D printing of non-assembly active hand prostheses using inexpensive 3D printers working on the basis of material extrusion technology. This...

Hydraulic catheter device for treating chronic total occlusion: A feasibility study

Chronic total occlusion (CTO) occurs in approximately a third of all patients with coronary artery disease and is one of the most challenging types of conditions to treat. Minimally invasive methods like percutaneous coronary intervention (PCI) show a high treating potential as well as low costs, short hospital stay and fast recovery. However,...
