Publication number: 20220370130Abstract: A laser fiber for use in performing a medical laser treatment includes an optical fiber and a fiber tip. The optical fiber includes a terminating end surface at a distal end. The fiber tip is positioned at the distal end of the optical fiber and includes a transmissive portion and a spacer portion. Laser energy discharged from the terminating end surface of the optical fiber is transmitted through the transmissive portion. The spacer portion defines a distal terminating end of the fiber tip that is spaced a predetermined distance from the terminating end surface of the optical fiber. The predetermined distance is set for shock wave generation for calculus destruction at the distal terminating end of the fiber tip.Type: ApplicationFiled: August 3, 2022Publication date: November 24, 2022Applicant: Boston Scientific Scimed, Inc.Inventors: Jian James ZHANG, Rongwei Jason XUAN, Danop RAJABHANDHARAKS
