Abstract: An example medical device includes a handle, an actuation mechanism coupled to the handle, and a delivery needle, wherein a proximal end of the delivery needle is coupled to a first end of the handle. A fluid delivery device is coupled to a second end of the housing, and a retractable sensor is positioned within the handle. The retractable sensor is configured to extend distally through a lumen of the delivery needle in a non-retracted position during placement of the delivery needle within a body of a patient, wherein actuation of the actuation mechanism causes the retractable sensor to retract proximally through the lumen of the delivery needle into the handle to a retracted position.

Abstract: A medical device includes a handle having a first end and a second end, a mixer positioned within the handle and an adapter coupled to the second end of the handle. A delivery needle includes a distal end, a proximal end, and a lumen extending from the distal end to the proximal end. The proximal end of the delivery needle is coupled to the first end of the handle. A sensor cable includes a distal end and a proximal end, and the proximal end of the sensor cable is positioned within the handle, and the distal end extends distally through the lumen of the delivery needle.

Abstract: A system includes a medical device and computer-readable media storing instructions that, when executed by a processor, cause operations to be performed, including: receiving a three-dimensional (3D) image of anatomy, processing the 3D image to extract a 3D model identifying anatomical structures of interest, receiving images captured by an imaging device of the medical device as the medical device is navigated through a body lumen to a target site, including a current image of the target site, receiving medical device spatial information from a position sensing system including a transmitter/receiver in or on the medical device, processing the images and spatial information to generate a 3D surface map of the body lumen, registering the 3D model to the patient using the map and spatial information, and generating and displaying a graphical user interface overlaying a representation of a position/trajectory of the anatomical structures of interest on the current image.

Abstract: A medical device is described that may include a handle and a needle extending distally from the handle. The needle may be configured to be at least partially inserted into a body, and may include a sheath and a core disposed in the sheath. The core may have a distal portion including a distal tip, and a proximal portion distinct from the distal portion. A proximal end of the distal portion may be coupled to a distal end of the proximal portion to define a cavity between the proximal end of the distal portion and the distal end of the proximal portion. The needle may further include a device of a position sensing system arranged in the cavity. The device may be a transmitter device or a receiver device. The position sensing system may be configured to determine a position or an orientation of the distal tip.

Abstract: Medical systems are described, including a medical system includes a first medical device and a second medical device. The first medical device includes a handle and an insertion portion with a first working channel. A distal portion of the insertion portion of the first medical device includes a first tracking element and at least one camera. The second medical device includes a handle and an insertion portion. A distal portion of the insertion portion of the second medical device includes a second tracking element. The first tracking element is configured to provide a signal that indicates a position or orientation of the distal portion of the first medical device. The second tracking element is configured to provide a signal that indicates a position or orientation of the distal portion of the second medical device.

Abstract: An assembly may have an axle. Rotation of the axle may cause deflection of a portion of a medical device. A collet may have an opening. The axle may extent through the longitudinal opening. An actuator may be configured to interact with the collet. A first configuration of the collet may permit rotation of the axle relative to the collet and a second configuration of the collet may inhibit rotation of the axle relative to the collet.
