A novel gallbladder umbrella stent (the Shai™ Stent) for prevention of stone migration and impaction: results on feasibility and short-term safety in a porcine model.

Background And Aims: Cholelithiasis is the most common biliary tract disorder. Surgery is the treatment of choice for symptomatic gallstones. Aims of this study were to investigate the feasibility and short-term safety of a new endoscopic procedure with a specially designed Nitinol gallbladder stent for blockage of gallstone migration, the Shai™ Stent.

Coronary sinus reducer stent for the treatment of chronic refractory angina pectoris: a prospective, open-label, multicenter, safety feasibility first-in-man study.

Objectives: This study sought to evaluate the safety of the Coronary Sinus Reducer (Neovasc Medical, Inc., Or Yehuda, Israel) as a potential alternate therapy for patients with refractory angina who are not candidates for conventional revascularization procedures.

Background: Increased coronary sinus (CS) pressure can reduce myocardial ischemia by redistribution of blood from nonischemic to ischemic territories.
