BACKGROUND Ionizing radiation administered intraluminally via catheter-based systems using solid beta and gamma sources or liquid-filled balloons has shown reduction in the neointima formation after injury in the porcine model. We propose a novel system that uses a 133-Xenon (133Xe) radioactive gas-filled balloon catheter system. METHODS AND RESULTS Overstretch balloon injury was performed in...

THERAPEUTIC catheter intervention probably started with Dotter and Judkins performance of transluminal treatment of arteriosclerotic obstruction of peripheral vessels.' Rashkind extended the therapeutic use of the catheter to intracardiac work with the performance of balloon atrial septostomy for transposition of the great arteries.2 Over the next 20 years, the field has blossomed, with removal...

The Digital Transformation (DX) potentially affects productivity and efficiency while offering high risks to organizations. Necessary frameworks tools help organizations navigate such radical changes are needed. An extended framework of DMM is presented through a comparative analysis various digital maturity models qualitative approaches expert feedback. level determination uses the Emprise tes...

Background—Ionizing radiation administered intraluminally via catheter-based systems using solid and sources or liquid-filled balloons has shown reduction in the neointima formation after injury in the porcine model. We propose a novel system that uses a 133-Xenon (Xe) radioactive gas-filled balloon catheter system. Methods and Results—Overstretch balloon injury was performed in the coronary ar...

This paper presents a constitutive model capable of predicting the anisotropic viscoelastic behavior of balloon film subject to large strains and cyclic loading. The model is based on the free volume theory of nonlinear viscoelasticity enhanced with a switching rule for treating loading and unloading differently. The model has been implemented in the finite element analysis program Abaqus/Stand...

data envelopment analysis (dea) models with interval inputs and outputs have been rarely discussed in dea literature. this paper, using the enhanced russell measurement proposes an extended model which permits the presence of interval scale variables which can take both negative and positive values. the model is compared with most well-known dea models of which include the ccr model, the bcc mo...

Bariatric endoscopy is a novel and expanding field in gastrointestinal (GI) endoscopy [1]. The most common bariatric endoscopy procedure is intragastric balloon (IGB) placement [2]. Currently most training occurs with a proctor and a patient. Of course, this approach has potential ethical disadvantages [3], and obtaining the skills for IGB placement using an ex vivo hands-on model would be an i...
