A load sensing assembly for a spinal implant includes a set screw having a central opening that extends from a first end of the set screw toward a second end of the set screw. The second end of the set screw is configured to engage with an anchoring member. The load sensing assembly includes an antenna, an integrated circuit in communication with the antenna, where the integrated circuit is positioned within the central opening of the set screw, and a strain gauge in connection with the integrated circuit. The strain gauge is located within the central opening of the set screw in proximity to the second end of the set screw.

The invention includes a system for generating virtual images of proposed and designated areas on a patient's anatomy that are to be treated in a RFA procedure. The images include a size, shape, and location of lesion/ablation patterns. The virtual images include dynamic (developing) or static (developed) lesions selected for the RFA procedure. The images are provided on at least one user interface that superimposes or overlays the lesion pattern(s) on an image of a patient's anatomy that undergoes the procedure. The images can be used to accurately and efficiently conduct RFA procedures and to record the procedures with enhanced visual data to confirm treated tissue areas. The invention further includes a diagnostic method of generating images in preparation for a RFA procedure, and a method of conducting the RFA procedure in which measured parameters determine the size and shape of the ablated areas achieved in the procedure.

An imaging system aka 3d camera operative in conjunction with a tube having two open ends, the system comprising active portions small enough to fit into the tube and an electronic subsystem including a hardware processor operative to receive image/s from the active portions and to generate therefrom at least one 3D image of a scene visible via one of the tube's open ends. The system may comprise a tracker configured to be secured to the tube, and a method for monitoring location, e.g. absolute location, of the tube, accordingly.

Systems and methods are provided for a surgical needle counting device for an operating room. An example system includes a collecting enclosure and a counting apparatus having a sensor configured for determining when a needle is dropped into the collecting enclosure. The counting apparatus is configured to maintain a count of needles introduced into a surgical field associated with the operating room and a count of needles accounted for in the counting apparatus.

A handheld surgical instrument includes a motor that transmits rotational movement to a drill bit of the handheld surgical instrument. The drill bit extends through a depth measurement module with a depth measurement extension, and a cannula, which extends forward from the drill to measure bore depth. The depth measurement extension is moveably mounted to the drill so as to extend into the rotor bore of the motor. As the drill advances forward, the depth measurement extension remains static. As a result of the advancement of the drill, the rotor extends over the proximal end of the depth measurement extension. A controller is configured to determine a breakthrough time and a breakthrough displacement of the drill bit based on displacement data and derived signals. The controller is further configured to determine a proper length of a screw to be used in a fixation surgical procedure based on the displacement data.

Systems and methods to monitor and track the treatment of bones using a bone correction system are provided. The method includes implanting growth modulating implants of a bone correction system in two or more bones of a patient. Each growth modulating implant includes an implant body having at least one sensor device embedded in the implant body. The method includes receiving sensor data from the sensor devices and determining an operational status of the growth modulating implants, based on the received sensor data. The method includes determining, by the processor, a longitudinal growth or growth rate between the two or more bones, based on the received sensor data and causing a display device to selectively display a graphical user interface (GUI) representative of at least one of the longitudinal growth and the growth rate of the patient.

In various embodiments, a medical device comprises a trocar including an awl and a cannula; two or more electrodes disposed on a distal portion of the trocar; an impedance bridge coupled to the two or more electrodes; and a processor coupled to the impedance bridge. In various embodiments, a computer-implemented method for evaluating tissue of a patient comprises recording, at one or more frequencies, one or more impedance measurements, wherein each impedance measurement is associated with two or more electrodes disposed on a distal portion of a trocar; comparing the one or more impedance measurements to one or more characteristic impedances associated with one or more tissue types; and determining, based on the one or more impedance measurements and the one or more characteristic impedances, one or more tissue types at a location associated with the distal portion of the trocar.

A system for treating heart disease, such as pulmonary hypertension or right heart failure, including an implantable component and external components for monitoring the implantable component is provided. The implantable component may include a compliant member, e.g., balloon, coupled to a reservoir via a conduit. Preferably, the compliant member is adapted to be implanted in a pulmonary artery and the reservoir is adapted to be implanted subcutaneously. The external components may include a clinical controller component, monitoring software configured to run a clinician's computer, a patient monitoring device, and a mobile application configured to run on a patient's mobile device.

A method for producing a surgical instrument is disclosed. The method comprises obtaining a handle, wherein the handle comprises a distal end comprising a shaft interface surface and a first set of magnetic elements. The method further comprises obtaining a shaft, wherein the shaft comprises a proximal end comprising a handle interface surface, a second set of magnetic elements, and a third set of magnetic elements. The method further comprises attaching the shaft to the handle, wherein the shaft interface surface is configured to engage the shaft at the handle interface surface, wherein an attractive magnetic force is configured to pull the handle towards the shaft when the first set of magnetic elements interact with the second magnetic elements, and wherein a repulsive magnetic force is configured to repel the handle from the shaft when the first set of magnetic elements interacts with the third set of magnetic elements.

A return pad of an electrosurgical system is disclosed. The return pad includes a plurality of conductive members and a plurality of sensing devices. The conductive members are configured to receive radio frequency current applied to a patient. The sensing devices are configured to detect at least one of the following: a nerve control signal applied to the patient; and a movement of an anatomical feature of the patient resulting from application of the nerve control signal.
