    摘要: A method and system for assessing tissue to determine a presence or absence of cancer cells. The method includes acquiring fluorescence lifetime (FLT) data from tissue and processing the FLT data to determine a FLT signal at each of a plurality of locations across the tissue. The method also includes determining FLT data at any of the plurality of locations above a threshold indicative a presence of cancer cells and generating a report indicating any of the plurality of locations above the threshold as indicative the presence of cancer cells.

    摘要: An access device includes an access assembly for percutaneously accessing an anatomical space in a patient. An aspiration assembly is operable to generate negative pressure in a fluidic channel of the device. The fluidic channel places the access assembly in fluid connection with the aspiration assembly. A fluid tube has a first tube end connected to the access assembly, a second tube end connected to the aspiration assembly, and a tube body. The tube body defines a manometer tube portion spaced apart from both the first and second tube ends. The manometer tube portion acts as at least part of a manometer when the device is in a manometer mode. The manometer tube portion has adjacent first and second manometer tube ends and an inflection point substantially reversing the direction of the manometer tube portion at a location spaced apart from both the first and second manometer tube ends.

    摘要: A method for detecting inflammatory activity, including: providing a catheter including a near-infrared fluorescence (NIRF) imaging system configured to perform NIRF imaging and an optical coherence tomography (OCT) imaging system configured to perform structural imaging; introducing a near-infrared fluorescent cathepsin-activatable imaging agent into a blood vessel; placing a distal end of the catheter within the blood vessel; obtaining, using the OCT imaging system, structural images of an atherosclerotic plaque within the blood vessel; obtaining, using the NIRF imaging system, NIRF images of the atherosclerotic plaque within the blood vessel; detecting the near-infrared fluorescent cathepsin-activatable imaging agent in the NIRF images; and identifying inflammation within the atherosclerotic plaque based on detecting the near- infrared fluorescent cathepsin-activatable imaging agent in the NIRF images.
