Abstract: A hybrid NIRF/IVUS imaging probe containing i) a spatially-truncated optical lens a substantially-planar surface of which is inclined with respect to an axis to reflect light, transmitted between proximal and distal ends of the probe, internally into a body of the lens, and ii) an acoustic transducer disposed sequentially with the optical lens on the axis of the probe while, at the same time, the optical and electrical members of the probe transmitting the radiative and mechanical energies (which the probe exchanges with a target bodily vessel) are parallel to one another within the housing of the probe. A method for operating the probe resulting in formation of spatially co-registered optical and acoustic images of the target. Related imaging system and computer-program product.

Abstract: An apparatus according to an exemplary embodiment of the present disclosure can include a first section(s) and a second section(s) which can have a cross-section that can be smaller than that of the first section. The first and second sections can be a particular section and can include memory-forming characteristics. An imaging arrangement can be in communication with the first section or the second section. The particular section can have a first shape when the particular section can be constrained, and the particular section can have a second shape when the particular section can be unconstrained. The second shape can be more curved than the first shape.

Abstract: The invention provides methods and compositions for determining whether a subject containing a stent immobilized in a blood vessel has asymptomatic stent thrombosis or is at risk of developing clinically symptomatic stent thrombosis. In one approach, the method involves imaging a region of the blood vessel that contains the stent using a probe that contains a fluorochrome, for example, a near-infrared fluorochrome, and a targeting moiety that binds a molecular marker indicative of the presence of asymptomatic stent thrombosis or the development of symptomatic stent thrombosis. To the extent that the subject displays one or more such markers, the probe binds to the markers and increases the local concentration of the probe in the vicinity of the stent. The imaging method identifies those patients that display a higher density of such markers in the vicinity of the stent. As a result, those patients can be monitored for, and/or treated to prevent, symptomatic stent thrombosis.

Abstract: System and method for obtaining information about a target structure. The system includes an optoelectrical element with an optical fiber having a core, a coating surrounding the core, an optical axis, a proximal end, and a distal end. The optoelectrical element also includes an electrical connector embedded within the coating along the optical axis between the proximal end and the distal end. A transducer is disposed at the distal end and electrically connected to the electrical connector. The transducer is operable to detect a first energy, generated in response to light that has been transmitted from the proximal end to the distal end and outcoupled from the distal end toward the target structure, and to convert the received first energy to an electrical signal to be transmitted along the electrical connector.
