Patent number: 10420458Abstract: The present teachings relate to an endoscope (and methods of manufacturing the same) having an illumination system that utilizes small diameter fibers for delivering bright, high quality light to a target site. In accordance with one aspect, an endoscope is provided having a phosphor-loaded, light emitting distal tip that can be energized via optical radiation delivered to the light-emitting distal tip via a small-diameter optical fiber (e.g., less than about 100 ?m in diameter) that extends through or along the length of the endoscope. The light-emitting distal tip can be energized by short wavelength laser light (e.g., radiation having wavelengths at 445 nm blue or 405 nm violet) coupled to the optical fiber's proximal end so as to deliver light of extremely high quality CRI (e.g., greater than 80, greater than 90, about 95).Type: GrantFiled: April 29, 2015Date of Patent: September 24, 2019Assignee: Boston Scientific Scimed, Inc.Inventor: Edward L.

Patent number: 9861437Abstract: Guided ablation instruments are disclosed for creating lesions in tissue, especially cardiac tissue for treatment of arrhythmias, including atrial fibrillation. In one aspect of the invention, a percutaneous catheter is disclosed with an endoscope positionable in the instrument's distal end region to obtain an image. The image allows the clinician to determine whether contact has been achieved (or blood has been cleared from an ablative energy transmission path) before ablation begins or while ablation is occurring. In one embodiment, percutaneous ablation catheters are disclosed having at least one central lumen and one or more balloon structures at the distal end region of the instrument. Also disposed in the distal end region are an illuminating light source and an endoscope capable of collecting sufficient light to relay an image to the user. The instruments can further include an ablation element.Type: GrantFiled: December 15, 2016Date of Patent: January 9, 2018Assignee: CARDIOFOCUS, INC.Inventors: Gerald Melsky, Jeffrey M.
