The closure of the left atrial appendage using a clip implant prevents strokes in patients with atrial fibrillation. Due to the rotating knob at the handle and the adjustable angle of the clip frame, this closure system allows exact positioning of the clip implant and optimal visibility before the surgeon inserts it into the heart. The instrument has a seamless design and is made of high-quality synthetic materials, while the ergonomic shape of the handle provides a perfect grip.
