Publication number: 20240130729Abstract: A system is configured to bring about anastomosis between two lumens in a patient or between two sections of a single lumen in a patient. The anastomosis system includes a first tissue-compressing element, a second tissue-compressing element, and an energy source. The energy source can be a thermal energy source or laser energy source. Tissue is interposed between the elements. Magnetic material incorporated into the tissue-compressing elements facilitates the alignment of the elements as well as compression of the interposed tissue. The energy source can deliver energy to tissue. This delivery of energy can cause local changes to the tissue that can help maintain positional stability of the implants, can bring about immediate patency of the anastomosis and can otherwise facilitate achieving desired outcomes for the patient.Type: ApplicationFiled: July 27, 2023Publication date: April 25, 2024Applicant: MYKA LABS, INC.Inventors: Daniel J. LASER, John H. JERMAN, Lee SWANSTROM

Patent number: 8558859Abstract: A laser printer arranged to print a pixellated image on laser sensitive tape includes a carriage on which are arranged two laser-beam sources delivering separately modulated laser-beams and optics for focusing the beams on the tape. The tape is mounted on a tape drive which drives the tape incrementally in one direction. The carriage is translated over the tape in a direction perpendicular to the tape-drive direction, while the modulated beams are focused. Two rows of the pixellated image are drawn across the tape in this manner. The tape is then incremented and a further two rows are drawn.Type: GrantFiled: April 20, 2011Date of Patent: October 15, 2013Assignee: Coherent, Inc.Inventors: John H. Jerman, Sergei Govorkov

Patent number: 8174751Abstract: Apparatus for marking a bitmap image on tape includes a scanning mirror which is incorporated in a micro-electro-mechanical system (MEMS). The MEMS is torsionally resonant at two frequencies one being about three time the other. The MEMS is excited to resonance by applying an AC signal to the actuators, causing the mirror to oscillate. The AC signal has components at the two frequencies. The magnitude and phase-relationship of the components can be selected such that the mirror oscillates in an approximation of a triangle-wave.Type: GrantFiled: April 12, 2011Date of Patent: May 8, 2012Assignee: Coherent, Inc.Inventor: John H.

Publication number: 20110164104Abstract: Apparatus for marking a bitmap image on tape includes a source of a modulatable laser-beam. The beam is directed to an oscillating mirror on a carriage translatable across the width direction of the tape. The oscillating mirror directs the beam to a focusing lens mounted on the carriage. The focusing lens is arranged to focus the beam to a focal-spot on the tape. As the carriage is translated, the focal-spot is swept reciprocally in a wave-like path across the tape. Modulation of the beam is arranged such that pixels of a plurality of rows of the bitmap image are printed in one traverse of the carriage. The tape is advanced incrementally and repeated traverses of the carriage are made to complete printing of the bitmap image.Type: ApplicationFiled: March 17, 2011Publication date: July 7, 2011Applicant: Coherent, Inc.Inventors: Sergei V.
