  • Publication number: 20240057935
    Abstract: Internal cervical exams during labor pose multiple challenges, including infection risk, subjectivity, invasiveness, and discomfort. A monitoring system described herein enables non-invasive and accurate measurement of cervical dilation and assessment of the baby's station. By inserting a narrow linear ultrasound probe through the working channel, high-resolution ultrasound images of the cervix can be obtained, eliminating the need for painful and subjective exams, reducing infection risk, and enhancing patient comfort. Moreover, the ultrasound capability allows for potential monitoring of maternal and fetal blood oxygenation levels, providing a comprehensive picture of fetal well-being.

  • Publication number: 20240023813
    Abstract: Apparatus, systems and methods for ultrasound and photoacoustic guidance of coronary procedures are disclosed herein. Certain embodiments include a first catheter comprising an ultrasound transceiver, and a second catheter comprising a proximal end and a distal end, with a photoacoustic excitation light transmitter positioned at the distal end of the second catheter.

  • Publication number: 20230149000
    Abstract: Apparatus and methods for tissue excision. In certain aspects, the apparatus and methods include an annular converging laser beam. The annular converging laser beam can be directed to a surface of a tissue and displace a portion of the tissue in a single or multiple laser pulses. In particular aspects, the dosimetry of the laser beam (e.g. the beam shape, pulse energy and pulse duration) can be controlled to eject the portion of the tissue in a manner to reduce damage to the displaced tissue and the surrounding tissue.

  • Publication number: 20220192537
    Abstract: The present invention features an optical detection system for SARS-CoV-2 or other pathogens, which includes a specialty mask. The specialty mask incorporates a SERS nanopatch for accumulating pathogenic particles from a wearers breath. When the SERS nanopatch receives incident NIR light, backscattered light from the SERS nanopatch is detected by a receiver and analyzed for a Raman spectral shift. Detection of the Raman spectral signature from the SERS nanopatch allows for determination if SARS-CoV-2 or another pathogen is present. In addition to the mask with a nanostructured surface for collecting pathogenic material, the system includes a laser source directed at the nanostructured surface, a detection system to collect backscattered light, a spectral analysis system to detect Raman shifted light, and an analysis system for determining if SARS-CoV-2 or another pathogen is present. AI image processing may be used to steer the laser beam safely to the nanopatch, avoiding eye contact.
