Abstract: The present disclosure is directed to arthroscopic visualization systems and methods. The visualization system can include a camera with a fluid inflow path, wherein a proximal end of the camera is configured to fluidly connect a fluid reservoir to the fluid inflow path. The system can also include a cannula with a lumen, wherein the lumen is configured to be fluidly connected to the fluid inflow path at a distal end of the camera. In addition, the system can also include a scope, wherein the scope is configured to be connected to the distal end of the camera and a portion of the scope is configured to be inserted into the lumen of the cannula.

Abstract: A drape configured to cover a handheld imager for use in a medical procedure, the drape including a frame that is removably mountable to a front portion of an enclosure of the imager; and at least one light transmissive component mounted to the frame and recessed with respect to a front of the frame such that the at least one light transmissive component is positioned in front of at least one enclosure window of the imager when the frame is mounted to the front portion of the imager.

Abstract: A method of displaying fluorescence intensity in an image includes displaying a target reticle covering a region of the image; calculating a normalized fluorescence intensity within the target reticle; and displaying the normalized fluorescence intensity in a display region associated the target.

Abstract: An imaging device may include a first illumination port to output first light having a first illumination distribution at a target to illuminate the target, a second illumination port to output second light having a second illumination distribution at the target to illuminate the target, the second illumination distribution being substantially similar to the first illumination distribution at the target, the second illumination port being spaced apart from the first illumination port, the first and second illumination distributions being simultaneously provided to the target and overlapping at the target. The illumination from the first and second ports may be matched to a same aspect ratio and field of view coverage as the imaging field of view.

Abstract: Described herein are introducer devices and methods for using an introducer device to facilitate passing an endoluminal instrument to a target region of a body cavity. An introducer device may include a tubular member having an inner wall that defines a channel configured to receive the endoluminal instrument and a plurality of projections disposed in the channel at perimetrically spaced apart locations around the inner wall, where the projections extend inward and are configured to offset the endoluminal instrument from the inner wall, thereby creating a space between the endoluminal instrument and the inner wall. A method for using an introducer device may include passing the endoluminal instrument to a first instrument insertion depth within the introducer device, advancing the introducer device in the body cavity, and advancing the endoluminal instrument to a second instrument insertion depth within the introducer device.

Abstract: An imaging device having an imaging field of view, the imaging device including at least one illumination port configured to output light for illuminating a target; an imaging sensor to detect light traveling along an optical path to the imaging sensor; and a first movable window positioned upstream of the sensor with respect to a direction of travel of light along the optical path, wherein the first movable window is configured to move into the optical path in a deployed position for modifying light received from the target.
