    Abstract: A sterile bag for covering medical equipment comprises: a barrier section, a flexible body section, and an attaching section. The flexible body section has a tubular shape extending from a proximal end to a distal end thereof, and an outer surface, an inner surface, and an open end. The barrier section is coupled to the proximal end, and the attaching section is formed at the distal end of the flexible body section. The barrier section is a rigid or semirigid component which attaches the sterile bag to a sterile component or to an unsterile component of the medical equipment in a pleaded or folded state. The flexible body section is configured to be deployed over the unsterile component so as to enclose within the inner surface thereof the unsterile component. The unsterile component is connectable to the sterile component through the central opening of the barrier section.

    Abstract: One or more devices, systems, methods, and storage mediums for detecting and guiding optical connection(s) using one or more imaging modalities are provided herein. Examples of applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, for Gastro-intestinal, cardio and/or ophthalmic applications, and being obtained via one or more optical instruments, such as, but not limited to, optical probes, catheters, capsules and needles (e.g., a biopsy needle). Devices, systems, methods, and storage mediums may include or involve a method, such as, but not limited to, for guiding and/or determining status of engagement and/or disengagement of one or more optical connections. A device, system, method, or storage medium may detect, monitor, and/or guide a probe/catheter to minimize, reduce, and/or avoid engagement and disengagement failures and to have a robust means of determining status of probe/catheter engagement to an apparatus or system.

    Abstract: Some embodiments of a device comprise a sheath, a first light-guiding component, a second light-guiding component, an optical-focusing component, and an optical-correction component. The second light-guiding component and the optical-focusing component are aligned on an optical axis. Also, the optical-correction component does not directly contact the optical-focusing component, and the optical-correction component is not positioned on the optical axis.

    Abstract: An apparatus includes an elongate member having proximal and distal portions; a rotatable drive cable disposed within the elongate member, the drive cable being connectable to a mechanism to which torque can be applied; and a control assembly mechanically coupled to the drive cable, and configured to disengage the mechanism from the drive cable when the applied torque exceeds a predetermined level, wherein disengagement of the mechanism from the drive cable causes rotation of the drive cable to stop or withdrawal of the drive cable.

    Abstract: One or more devices, systems, methods and storage mediums for performing common path optical coherence tomography (OCT) with a controlled reference signal and efficient geometric coupling are provided. Examples of such applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, for Gastro-intestinal, cardio and/or ophthalmic applications, and being obtained via one or more optical instruments, such as, but not limited to, optical probes (e.g., common path probes), common path catheters, common path capsules and common path needles (e.g., a biopsy needle). Preferably, the OCT devices, systems methods and storage mediums include or involve a reference reflection or a reference plane that is at least one of: (i) disposed in the collimation field or path; and (ii) is perpendicular (or normal) or substantially perpendicular (or substantially normal) to light propagation. One or more embodiments may include beam shaping optics to properly image luminal or other hollow structures or objects.

    Abstract: A catheter, comprising: a drive cable having cylindrical opening extending from a proximal end to a distal end along a longitudinal axis thereof; an imaging probe having an optical fiber arranged inside the drive cable and a distal optics assembly fixedly attached to the drive cable at the distal end thereof; a first radiopaque marker arranged at a distal end of the drive cable at a position distal and parallel to the distal optics assembly; and a second radiopaque marker arranged at a predetermined distance from the distal end of the drive cable at a position proximal to the distal optics assembly. The second radiopaque marker is arranged concentric or coaxially to the longitudinal axis in a space between the longitudinal axis and an outer surface of the drive cable.

    Abstract: A fiber optics polarization controller comprises: an optical fiber and multiple polarization stages. A first stage comprises: a motor having a hollow shaft spanning from a proximal end to a distal end along a rotational axis; and a fiber paddle affixed to and adapted to rotate with the hollow shaft. The fiber paddle has a ring-shaped body with two openings arranged opposite to each other around the ring-shaped body. A first opening of the fiber paddle is connected to the distal end of the hallow shaft substantially collinear with the rotational axis of the motor. The optical fiber is arranged spanning through the hollow shaft, entering the fiber paddle through the first opening, following around the ring-shaped body to form a fiber loop, and exiting the ring-shaped body through the second opening. A second stage is arranged in series with the first stage.
