Spinal Needle
Clinical indications for epidural anesthesia and analgesia have expanded significantly over the past several decades. Epidural analgesia is often used to supplement general anesthesia (GA) for surgical procedures in patients of all ages with moderate-to severe comorbid disease; provide analgesia in the intraoperative, postoperative, peripartum, and end-of-life settings; and can be used as the primary anesthetic for surgeries from the mediastinum to the lower extremities. In addition, epidural techniques are used increasingly for diagnostic procedures, acute pain therapy, and management of chronic pain. Epidural block may also reduce the surgical stress response, the risk of cancer recurrence, the incidence of perioperative thromboembolic events, and, possibly, the morbidity and mortality associated with major surgery.
Stent Graft (Wrapsody)
Dialysis patients can often experience complications due to stenosis and occlusions in the dialysis outflow circuit. This can lead to repeated interventions, frequent trips to the hospital, and inadequate dialysis treatments. The Merit WRAPSODY Cell-Impermeable Endoprosthesis is built to combat these challenges and extend long-term vessel patency rates.
Ureteral Stent
A ureteral stent, or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters.
