Patent number: 11998269Abstract: Articles of manufacture, including terminations of or attachments to optical fibers are configured to substantially prevent axial emission and redirect radially most if not all light emanating from optical fibers. In that, a termination may include a fiber cap of a unitary construction of a tube and an optical element disposed to face a sealed end of the tube and dividing a hollow of the tube and having a conical surface, or an optical element dividing the hollow and complemented by a cone. An example of termination includes an optical fiber element having an up-tapered end with a maximum taper-diameter exceeding the core-diameter and ending at a conical element with an apex angle from about 70° to about 100°. Articles of manufacture additionally including mounting contraptions cooperating such terminations with cannulae to form an attachment to a laser system. Methods for transmitting light through such articles of manufacture.Type: GrantFiled: October 10, 2023Date of Patent: June 4, 2024Assignee: CYCLONE BIOSCIENCES, LLCInventors: Stephen E.

Patent number: 10993768Abstract: Radial emission optical fiber terminations that include conical elements can prevent axial emission and redirect all incident light to radial positions. One termination includes an optical fiber having an up-tapered terminus, the up-tapered terminus having a maximum taper diameter of at least 1.5 times the core diameter and ending at a cone-tip which has an apex angle in a range of about 70° to about 100°. Another termination includes a fiber cap that is a unitary construction of a glass tube and an optical element that bisects the glass tube. The glass tube includes an open end adapted to receive an optical fiber and a closed end. The optical element, consisting of fused quartz or fused silica, has an input face proximal to the open end of the glass tube and a conical face proximal to the closed end of the glass tube.Type: GrantFiled: September 6, 2018Date of Patent: May 4, 2021Assignee: Cyclone Biosciences, LLCInventors: Stephen E.

Patent number: 10105184Abstract: Embodiments of the invention are directed to a laser ablation system. In one embodiment, the laser ablation system comprises a shaft, a balloon, a laser fiber and a viewing fiber. The shaft has a proximal end and a distal end. The balloon is attached to the distal end of the shaft, a portion of which is within the balloon. The laser fiber has a distal end comprising a light dispenser that is configured to deliver laser light through the balloon. The viewing fiber is configured to image an interior balloon. In accordance with another embodiment, the laser ablation system comprises a shaft, a balloon and a laser fiber. The shaft has a proximal end and a distal end. The balloon is attached to the distal end of the shaft, which is within the balloon. The balloon includes an inflated state, in which the balloon is shaped to conform to a cavity of a patient. The laser fiber has a distal end comprising light dispenser that is configured to deliver laser light through the balloon.Type: GrantFiled: July 13, 2016Date of Patent: October 23, 2018Assignee: Boston Scientific Scimed, Inc.Inventors: Michael T.

Patent number: 9433467Abstract: Embodiments of a laser ablation system include a shaft, a balloon and a laser fiber. The shaft has a proximal end and a distal end. The balloon is attached to the distal end of the shaft, a portion of which is disposed within the balloon. A light dispenser at a distal end of the laser fiber is configured to deliver laser light through the balloon. A central axis of the balloon is aligned with a longitudinal axis of the shaft. The balloon has a variable transparency such that the transmission of laser light through the balloon is non-uniform along the central axis. Accordingly, an energy of laser light transmitted from the light dispenser through the balloon to the targeted tissue varies due to the variable transparency of the balloon.Type: GrantFiled: October 23, 2014Date of Patent: September 6, 2016Assignee: Boston Scientific Scimed, Inc.Inventors: Michael T Beck, Edouard A. Koulick, Robert E. Lund, Douglas L. Evans, Samuel L. Will, Stuart F. Watson, Hyun Wook Kang, Justin M. Crank, Somany Dy, Micah D. Thorson
