We herein present our initial experience of a short series with the Allium™ Bulbar Urethral Stent (BUS) in the management of bulbar urethral disease. This Allium™ stent is a self-expandable metal stent which is intended for temporary placement. Our series is a retrospective analysis of 15 BUS placements in 13 patients conducted during 2014 to 2016. BUS was placed successfully after visual inter...

Self expandable metal stent can be used both as palliative treatment for malignant colorectal obstruction and as a bridge to surgery in patients with potentially resectable colorectal cancer. Here, we report a case of successful relief of malignant stomal obstruction using a metal stent. A 56-year-old man underwent loop ileostomy and was given palliative chemotherapy for ascending colon cancer ...

BACKGROUND self-expanding metal stents are currently being used as a definitive palliative treatment for malignant colorectal obstruction in patients with incurable disease. Few studies have followed large numbers of patients from stent placement until death, and those few have reported conflicting results in the long-term clinical outcome data. AIMS this study evaluated the clinical effectiv...

BACKGROUND AND AIM Covered self-expandable metal stents (EMS) were recently developed to overcome tumour ingrowth in conventional EMS. However, supporting evidence for the efficacy of covered EMS is lacking. PATIENTS AND METHODS We enrolled 112 patients with unresectable distal biliary malignancies. They were randomly assigned to polyurethane covered (n = 57) or original diamond stent (n = 55...

Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive technique to treat inoperable patients who suffer from end-stage calcific aortic valve disease. Although TAVR patients are prone to atrioventricular (A-V) conduction disturbances and arrhythmias, no previous studies numerically modeled the influence of this procedure on heart block mechanisms. The current study proposes a met...

Metal stents and, more recently, polymer-coated metal stents are used to stabilize dissections, eliminate vessel recoil, and guide remodeling after balloon angioplasty and other treatments for arterial disease. Bioresorbable polymeric stents are being developed to improve the biocompatibility and the drug reservoir capacity of metal stents, and to offer a transient alternative to the permanent ...

Virtual design tools are gaining more and more importance in the development and evaluation of medical devices. Inherently each medical device is subjected to (very) different (patient) specific loading conditions and thus requires dedicated simulation strategies. In addition, specific post-processing of the data obtained from the numerous simulations is needed to evaluate the device behavior. ...

Background—Transcatheter aortic valve implantation (TAVI) is associated with a higher risk of neurological events for both the transfemoral and transapical approach than surgical valve replacement. Cerebral magnetic resonance imaging has revealed more new, albeit clinically silent lesions from procedural embolization, yet the main source and predominant procedural step of emboli remain unclear....

Intestinal obstruction is a common complication in patients with advanced gastrointestinal malignancies. In the last two decades, endoscopic placement of duodenal stents has become a mainstay of palliative treatment in patients with unresectable obstructive duodenal pathology. Self-expandable metal stents have been reported to have excellent success rates, besides dramatically improve the patie...
