  • Opto-acoustic imaging devices and methods
    Patent number: 8753281
    Abstract: In one aspect, the invention relates to a probe. The probe includes a sheath, a flexible, bi-directionally rotatable, optical subsystem positioned within the sheath, the optical subsystem comprising a transmission fiber, the optical subsystem capable of transmitting and collecting light of a predetermined range of wavelengths along a first beam having a predetermined beam size. The probe also includes an ultrasound subsystem, the ultrasound subsystem positioned within the sheath and adapted to propagate energy of a predetermined range of frequencies along a second beam having a second predetermined beam size, wherein a portion of the first and second beams overlap a region during a scan.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: June 17, 2014
    Assignee: Lightlab Imaging Inc.
    Inventors: Joseph M. Schmitt, Christopher Petersen, Toro Ohasi, Tetsuya Nakamatsu

  • Fluid occluding devices and methods
    Publication number: 20060095065
    Abstract: In one aspect, the invention relates to a method of occluding blood in a blood vessel during the imaging of a portion of the blood vessel. The method includes the steps of selecting an inflatable element such that diameter of the inflated inflatable element is greater than the diameter of the blood vessel being imaged, introducing the inflatable element into the blood vessel and underinflating the inflatable element such that the vessel wall is not substantially deformed by the inflatable element, the inflatable element substantially occluding the blood vessel to reduce imaging distortion resulting from vessel fluids.
