The present disclosure concerns embodiments of an implantable perfusion device that can be implanted in an injured blood vessel to control bleeding without occluding the vessel. In one specific implementation, the perfusion device can be implanted percutaneously into a patient's descending aorta to control bleeding at the site of a ruptured portion of the aorta (known as torso hemorrhage) while still allowing for the antegrade flow of blood from a location upstream of the ruptured portion of the aorta to a location downstream of the ruptured portion of the aorta. The perfusion device can be left inside the patient as the patient is transported to a medical facility where the injury can be repaired. Following repair of the vessel, the perfusion device can be withdrawn from the patient.

This disclosure relates generally to systems and methods for localizing a device relative to an instrument. A sensor of the instrument can be monitored for a change in signaling during a first transition of the device relative to the instrument. The sensor can further be monitored for another change in signaling provided by the sensor of the instrument in response to a second transition of the device relative to the instrument. A transition distance difference can be determined between the first transition and the second transition. A location of the device relative to the instrument can be determined based on a location of the instrument and the transition difference distance.

Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system may include one or more markers implantable within or around the target tissue region, and a probe for transmitting and receiving electromagnetic signals to detect the one or more markers. During use, the marker(s) are into a target tissue region, and the probe is placed against the patient's skin to detect and localize the marker(s). A tissue specimen, including the lesion and the marker(s), is then removed from the target tissue region based at least in part on the localization information from the probe.

A system for displaying enhanced reality images of a body includes a fiducial marker patch, an external medical imaging system, a camera, a tool, a controller, and a display. The fiducial marker is configured to be placed on the body. The tool is configured to be inserted into the body for a medical procedure. The controller is configured to develop 2D or 3D images of the tool positioned within the body in real time based upon images from the external medical imaging system and the camera. The display is configured to display the 2D or 3D images in real time.

Provided herein are systems, devices, assemblies, and methods for generating exciter signals, for example, to activate a remotely located tag. The systems, devices, assemblies, and methods find use in a variety of application including medical applications for the locating of a tag in a subject.

An optical tracking system includes at least one tracking array for generating and optically transmitting data between 1 and 2,000 MB/s. At least one tracker for optically receiving the optically transmitted data between 1 and 2,000 MB/s is also provided. The tracking system is used not only for tracking objects and sending tracking information quickly but also providing the user or other components in an operating room with additional data relevant to an external device such as a computer assisted device. Orthopedic surgical procedures such as total knee arthroplasty (TKA) are performed more efficiently and with better result with the optical tracking system.

A transponder includes an encapsulant defining a cavity having a spherical internal profile. A suspension medium and a core are contained within the cavity. The core includes a rod having a first end and a second end, and defines a longitudinal axis between the first end and the second end. The longitudinal axis of the rod defines an axis of sensitivity of the transponder, and the core defines a center of gravity closer to the second end of the rod as compared to the first end of the rod. The center of gravity is disposed along the longitudinal axis of the rod. The transducer includes a conductive coil wrapped around the rod, and a capacitor coupled to the conductive coil. The core self-orients itself such that the axis of sensitivity of the transponder is parallel with a plumb to gravity axis.

Disclosed are devices, systems and methods for providing sterile and cost-affordable handheld surgical devices with tactile operable controls. In some aspects, a surgical device includes a surgical probe including a probe detector and a set of operable controls; an exterior shell casing including an opening at one end leading to an interior cavity structured to have a size and shape to fit the surgical probe within and position the probe detector in a first region and a handle of the surgical probe in a second region, in which the first region of the exterior shell casing is configured to be inserted into an incision of a patient's body and the second region is configured to provide a user of the surgical device utilization of the operable controls of the surgical probe through the exterior shell casing; and a cap attachable to the exterior shell casing to close the opening.

A surgical robotic system includes a robotic arm, an injection needle supported by the robotic arm, a localization system, an imaging system, at least one control unit. The at least one control unit is configured to perform at least one controlled loop carried out after a dispense of cement with the injection needle, in the region of interest of a patient. This controlled loop includes imaging the region of interest, with the imaging system, to provide an updated set of imaging data; using at least partially the updated set of imaging data to calculate an updated set of injection parameters; and using at least one parameter of the updated set of injection parameters to control the dispense of cement through the injection needle. Also disclosed is a method for controlling a surgical robotic system.

Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.
