An elongated access device used in a medical system. The elongated access device slidably receives a medical tool and an ultrasound probe. The elongated access device includes a sheath and an intraluminal tip attached to the distal end of the sheath. The intraluminal tip includes ramp and nose donuts being spaced apart from one another and configured to be attached to one or more elongated sleeves. One or more orientation pins are engaged with the respective ramp and nose donuts and may be anchored within the sheath. The medical tool is engaged with a ramp formed in the ramp donut or a ramp received within the ramp donut. The ultrasound probe is configured to engage with the intraluminal tip so as to ensure that the medical tool directionality is oriented toward a target during a procedure.

An apparatus, system and process for identifying one or more different tissue types are described. The method may include applying a configuration to one or more programmable light sources of an imaging system, where the configuration is obtained from a machine learning model trained to distinguish between the one or more different tissue types captured in image data. The method may also include illuminating a scene with the configured one or more programmable light sources, and capturing image data that includes one or more types of tissue depicted in the image data. Furthermore, the method may include analyzing color information in the captured image data with the machine learning model to identify at least one of the one or more different tissue types in the image data, and rendering a visualization of the scene from the captured image data that visually differentiates tissue types in the visualization.

Tools and systems for the delivery of medical devices or components, and more specifically, to tools and systems that assist or facilitate the delivery of one or more medical device or component over, onto, into, or against, another medical device or component are provided. More specifically, delivery tools and systems for the placement of an endoscopic device over, onto, into, or against, another instrument or endoscope are provided.

Various rotatable shafts and linkage mechanisms configured to allow imaging and access to tissue within a body are provided. In an exemplary embodiment, an introducer system has a rotatable sheath and a linkage that can rotatably engage each other. The rotatable sheath has a distal portion extending at a non-zero angle relative to a proximal portion thereof. The linkage has an exit lumen on its distal end and a plurality of entry lumens on its proximal end. The linkage merges the plurality of entry lumens into the exit lumen, and the exit lumen is aligned with the rotatable sheath upon engagement. Fluid and/or surgical instruments can thus be passed from the plurality of entry lumens of the linkage, through the exit lumen of the linkage, and into the rotatable sheath. The linkage and the rotatable sheath can both receive an imaging device therethrough.

An endoscopic grabber apparatus includes a proximal housing, a distal assembly, a flexible shaft extending between the proximal housing and the distal assembly, a flexible member within the flexible shaft having a distal end portion connected to the distal assembly and a proximal end portion connected to the proximal housing, and a camera within the distal assembly. A distal end portion of the flexible member is movably disposed within the distal assembly. A proximal end portion of the flexible member is connected to an actuator within the proximal housing. Actuation of the proximal end portion moves the distal end portion of the flexible member such that a protrusion extending from the distal end portion deforms to form part of a grabber. The camera is configured to capture an image including a tip portion of the protrusion. The endoscopic grabber device can include multiple protrusions configured to grab a target object

An endoscope treatment tool includes: a cylindrical cap attached to an outer side of a distal-end section of an endoscope and having first and second radial directions intersecting each other; a treatment tool supported at an outer side of the cap in the first radial direction to be movable in the longitudinal direction; and a linear flexible coupling member coupling the treatment tool with the cap such that the grasper reaches a position where the grasper protrudes from a distal end of the cap. A swing section of the coupling member couples the cap with the treatment tool to allow relative movement in the second radial direction, and, in response to pressed forward in the longitudinal direction by the treatment tool, swings about a swing axis extending in the second radial direction while generating a tensile force and bending the treatment tool inward in the first radial direction.

A multifunctional visualization instrument is provided that, in certain embodiments, includes a body having a proximal end and a distal end. The multifunctional visualization instrument includes a display screen on the body and a camera stick at the distal end of the body and comprising an arm and a camera. The arm of the camera stick is sized to fit within a channel of a removable laryngoscope blade. The multifunctional visualization instrument includes a port on a surface of the laryngoscope, configured to mate with an introducer and a steering input for steering the introducer, displayed on the display screen simultaneously with an image of the patient captured by the camera.

An adapter device for a surgical instrument includes an adapter member connectable to and separable from the surgical instrument, the adapter member having a first end, a second end, a longitudinal axis extending from the first end to the second end, and a connection structure configured to connect to the surgical instrument, and a mounting member connectable to and separable from the adapter member for mounting an additional instrument to the adapter member.
