Abstract: Knotless, all inside self-locking constructs and methods of tissue repairs are disclosed herein. A flexible strand can be passed through a friction-based locking mechanism to create a plurality of closed, knotless, continuous, adjustable, flexible loops having adjustable perimeters, the loops being located between a loop interconnection and two terminal ends.

Abstract: A system for performing surface analysis on a material, includes a pulsed electron source that forms a monochromatic beam of incident electrons; means for conveying the incident electrons to the surface of a sample of material, so as to form backscattered electrons, and the backscattered electrons to detecting means, the conveying means comprising at least one electron optical system; means for detecting the backscattered electrons; the pulsed electron source comprising: a source of atoms; a continuous-wave laser beam configured to form a laser excitation zone able to excite the atoms to Rydberg states; a pulsed electric field on either side of the laser excitation zone, the pulsed electric field being configured to ionize at least the excited atoms and to form a monochromatic beam of electrons.

Abstract: This disclosure relates to surgical fixation systems and methods. The surgical fixation systems may include one or more loops and one or more reinforcement materials. The surgical fixation systems can be used in various knotless tissue repair procedures.
