BACKGROUND Catheter ablation of atrial fibrillation is associated with the potential risk of periprocedural stroke, which can range between 1% and 5%. We developed a prospective database to evaluate the prevalence of stroke over time and to assess whether the periprocedural anticoagulation strategy and use of open irrigation ablation catheter have resulted in a reduction of this complication. ...

We have been privileged in the past decades to witness the logic of scientific discovery bringing to light the mechanistic understanding and modern treatment of atrial fibrillation (AF). From being experimental in their early days, catheterbased techniques are now recommended as a Class 1 therapy for treatment of patients with symptomatic AF refractory to at least one membrane active antiarrhyt...

Objective: We designed a novel technique of suctioning flexible ureteroscopy with automatic control of renal pelvic pressure (RPP) by a patented system including a pressure-measuring ureteral access sheath (UAS) and an irrigation and suctioning platform. We sought to compare RPP values measured by the patented system and a nephrostomy catheter at different phases of flexible ureteroscopy. Mater...

BACKGROUND Catheter ablation of ventricular tachycardia (VT) associated with structural heart disease is more difficult than ablation of idiopathic VT. The larger size of responsible reentrant circuits contributes to the difficulty in achieving an adequate ablation lesion with conventional techniques. Recently, cooling of the ablation electrode by saline irrigation has been shown to increase RF...

Breast reconstruction with implantable devices is now the most common type of technique utilized following mastectomy. Because infections are one of the most common complications for the procedure and currently no one method has been proven to stand above the rest, we designed and implemented a novel technique that employed 24 hours continuous triple-antibiotic irrigation via a catheter-based s...

OBJECTIVE During partial nephrectomy, renal hypothermia has been shown to decrease ischemia induced renal damage which occurs from renal hilar clamping. In this study we investigate the infusion rate required to safely cool the entire renal unit in a porcine model using retrograde irrigation of iced saline via dual-lumen ureteral catheter. MATERIALS AND METHODS Renal cortical, renal medullary...

Inspissated bile syndrome in a 6 week old boy was unresponsive to oral ursodesoxycholic acid. Intraoperative cholangiography revealed complete obstruction of the common bile duct. Therefore, the gallbladder fundus was pulled out through a laparoscopy port site and sutured to the fascia. A catheter was positioned into the infundibulum for irrigation with ursodesoxycholic acid. At day 8 complete ...

used for instilling fluids into, withdrawing fluids from, splinting, or suppressing bleeding of the alimentary tract. This device may incorporate an integral inflatable balloon for retention or hemostasis. This generic type of device includes the hemostatic bag, irrigation and aspiration catheter (gastric, colonic, etc.), rectal catheter, sterile infant gavage set, gastrointestinal string and t...

OBJECTIVES We sought to test how catheter ablation using an open irrigation catheter (OIC) compares with standard catheters for pulmonary vein antrum isolation. BACKGROUND Open irrigation catheters have the advantage of delivering greater power without increasing the temperature of the catheter tip, which enables deeper and wider lesions without the formation of coagulum on catheters. METHO...
