Abstract: A waveguide including first and second sections has a first molded optic material forming a portion of the geometry of one or more Bragg gratings disposed on one surface of the first section of the waveguide. Similarly, a second molded optic material forming another portion of the geometry of one or more Bragg gratings is disposed on one surface of the second section of the waveguide. Further, a photopolymer material is deposited on the first molded optic material. As the first and second sections are coupled, a waveguide is formed with a layer of photopolymer material disposed in the waveguide with the layer of photopolymer material having a geometry defined by the first and second molded optic materials. Bragg grating holograms are then recorded in the layer of photopolymer material, resulting in a waveguide with a plurality of Bragg gratings.

Abstract: Provided is a medical device comprising a handle comprising a distal hub, a proximal hub, and a middle hub disposed between the distal hub and the proximal hub. The medical device may comprise an outer sheath coupled with the distal hub, a basket configurable in a deployed state and an undeployed state, and a jet tube shaft coupled with the proximal hub, the jet tube shaft coaxial to the outer sheath. The jet tube shaft may comprise a jet tube comprising an aperture configured to expel a fluid, a jet tube lumen sized to accept the jet tube, and an evacuation lumen.

Abstract: Systems, apparatus and methods for removing tissue of various densities from a surgical site in a minimally invasive manner are provided. The invention may include a fine stream of sterile saline, coupled with a suction effect to cut and remove tissue. A power console may be coupled with a handpiece. The power console may utilize an electric motor, thereby transmitting pressurized sterile saline through a high-pressure tube. The distal end may deliver the saline across a window as a high velocity jet stream which, when coupled with the pressure gradient, pulls and then cuts the target tissue into the cutting window and removes it. The tissue and waste saline may then travel down an evacuation lumen to a waste container. By adjusting pressures, tissue types of various densities may be debrided while minimizing disturbance of surrounding tissue.
