A longitudinal-positioning indicator, improved marking grid, and a method of use. The longitudinal-positioning indicator includes a substrate that has a first side on which a set of longitudinal-positioning guidelines are disposed, the set of longitudinal-positioning guidelines configured to indicate a position along a length of the longitudinal-positioning guidelines based on a cross-section of the longitudinal-positioning indicator taken substantially orthogonally to the set of longitudinal-positioning guidelines. The substrate also has a second side that is at least partially coated with an adhesive.

Disclosed is a bone cutting and shortening system and the method of using the same, the system comprising a bone plate and a cutting guide adapted to slidingly engage by inserting the cutting guide into the bone plate from the overhead direction, the cutting guide adapted to facilitate parallel cutting planes on a bone at precisely ascertainable offset distances, and the bone plate adapted to stabilize the shortened bone after cutting.

A method of performing bariatric surgery using a robotic surgical system includes positioning a gastrectomy device in a selected location in a stomach; applying an adherent material to the stomach along a desired transection line; and cutting the stomach along the desired transection line delineated by the adherent material.

An ultrasound probe captures real-time images of patient anatomy, which are analyzed by a processor to extract salient features pertaining to an anatomical structure. By tracking the location and orientation of the ultrasound probe, a model of that anatomical structure can be created. A visual indication of the position of segments of the anatomical structure can be presented holographically to a user of an augmented reality headset to provide information extracted from the ultrasound imaging, such as holographic display of a model of the anatomical structure at the approximate location of the visual field of the headset corresponding to the physical location of the actual anatomy being viewed by a user, without presenting the entirety of the ultrasound image to the user.

Embodiments include, for example, mechanical release systems for implantable medical devices.

A catheter system for ablation of tissue around a blood vessel, e.g., the pulmonary artery, to reduce neural activity of nerves surrounding the blood vessel. The catheter system includes an elongate shaft having a proximal portion coupled to a handle, and a distal portion. The distal portion includes a transducer and an expandable anchor, which may be actuated to transition between a collapsed delivery state and an expanded deployed state where the anchor centralizes the transducer within the blood vessel. The transducer may be actuated to emit energy to reduce neural activity of the nerves surrounding the blood vessel. Systems and method are further provided for confirming that neural activity of the nerves surround the blood vessel has been sufficiently reduced.

Augmented and/or mixed reality systems for performing various types of arthroplasty are provided, along with methods of performing various types of arthroplasty using such augmented reality systems. More particularly, the augmented and/or mixed reality system and method is used to achieve accurate bone preparation, implant placement and orientation, and biomechanical restoration in orthopaedic arthroplasty procedures. Preparation, implantation, and adjustment of arthroplasty surgical sites, prosthetic components, and tailoring and positioning of installed prosthetic components can be guided using augmented reality overlays, projections, or combined imaging of a surgeon's real-world view.

A method includes obtaining, via one or more processors, three-dimensional data representing a patient's bone, obtaining, via the one or more processors, three-dimensional data representing at least portions of a patient specific bone jig, the patient specific bone jig having an inner surface portion matched to an outer surface portion of the patient's bone, obtaining, via the one or more processors, image data representing the at least portions of the patient specific bone jig registered to the patient's bone, and generating, via the one or more processors, data representing a location and an orientation of the patient's bone based on the obtained image data, the obtained three-dimensional data representing the patient specific bone jig, and the obtained three-dimensional data representing the patient's bone. In another embodiment, a patient specific bone jig with predetermined spatial indicia registered to a portion of the patient's bone may be employed with point sampling.

A biopsy probe mechanism includes an elongate sample receiving member having a longitudinal axis and a sample receiving notch. A cutting cannula is arranged coaxially with the elongate sample receiving member. The elongate sample receiving member and the cutting cannula are movable relative to one another along the longitudinal axis between a first relative position and a second relative position. A plurality of echogenic features include a first echogenic feature established on the elongate sample receiving member and a second echogenic feature established on the cutting cannula. The first echogenic feature is in longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the first relative position. The first echogenic feature is out of longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the second relative position.

Imaging systems projecting augmented information on a physical object that at a minimum include a processor, a memory device operably connected to the processor, a projector operably coupled to the processor, and a distance-measuring device operably connected to the processor. The memory device stores augmented image information, and the processor is configured to project augmented image information onto the physical object. The distance-measuring device is configured to measure the distance to the physical object. The processor uses distance measurement information from the distance measuring device to adjust scaling of the augmented image information. The processor provides the scale adjusted augmented image information to the projector. System can also be used for fluorescence imaging during open surgery, for endoscopic fluorescence imaging and for registration of surgical instruments.
