  • Publication number: 20140005715
    Abstract: A vena cava filter catheter includes a catheter having a lumen disposed therethrough and at least one strand of biocompatible wire. The at least one strand has a first state in which the at least one strand has an elongate geometry suitable for traversing the lumen of the catheter and a second state in which the at least one strand assumes a pre-set geometry in which the at least one strand assumes a tortuous configuration adapted to occupy a space approximating a luminal diameter of an inferior vena cava.

  • Publication number: 20130090536
    Abstract: Provided herein are systems, methods, and apparatuses for an analyte sensor. In one aspect, an analyte sensing device comprises a sensor body member including at least one nanopore and an optical conduit in optical communication with the sensor body member. The optical conduit transmits optical energy to the sensor body member and receives reflected optical energy back from the sensor body member. A photodetector is optically coupled to the optical conduit to determine an optical parameter from the reflected optical energy.

  • Patent number: 8280470
    Abstract: The invention generally relates to systems, methods, and apparatuses for an analyte sensor. In one aspect, an analyte sensing device comprises a sensor body member including at least one nanopore and an optical conduit in optical communication with the sensor body member. The optical conduit transmits optical energy to the sensor body member and receives reflected optical energy back from the sensor body member. A photodetector is optically coupled to the optical conduit to determine an optical parameter from the reflected optical energy.

  • Publication number: 20110152771
    Abstract: The present invention relates to a rotating catheter tip for optical coherence tomography based on the use of an optical fiber that does not rotate, that is enclosed in a catheter, which has a tip rotates under the influence of a fluid drive system to redirect light from the fiber to a surrounding vessel and the light reflected or backscattered from the vessel back to the optical fiber.

  • Publication number: 20090043191
    Abstract: The invention relates to an apparatus for in vivo imaging. More specifically, the present invention relates to a catheter that incorporates an Optical Coherence Tomography (OCT) system and an Intravascular Ultrasound (“IVUS) system for concurrent imaging of luminal systems, such as imaging the vasculature system, including, without limitation, cardiac vasculature, peripheral vasculature and neural vasculature.

  • Publication number: 20080085523
    Abstract: A method and kit for detecting Trichomonas vaginalis infection in a human subject are disclosed. In the method, a body-fluid sample such as a vaginal-swab sample or urine is obtained from the subject and contacted with an antibody specific against a Trichomonas adhesin peptide, forming an antibody-adhesin peptide complex if the subject is infected with Trichomonas. The presence or absence of the complex establishes, with a reliability of at least 80%, in the case of a vaginal swab sample, and with a reliability of at least 40% in the case of a urine sample, the presence or absence, respectively, of Trichomonas infection in the subject. A preferred test kit employs a dry-strip, sandwich assay, format.
