A sterile drape, a surgical system with the drape, and a draping method are provided. In one embodiment, a sterile drape includes a plurality of drape pockets, each of the drape pockets including an exterior surface to be adjacent a sterile field for performing a surgical procedure and an interior surface to be adjacent a non-sterile instrument manipulator coupled to a manipulator arm of a robotic surgical system. The drape further includes a plurality of flexible membranes at a distal face of each of the drape pockets for interfacing between outputs of an instrument manipulator and inputs of a respective surgical instrument, and a rotatable seal adapted to couple a proximal opening of each of the drape pockets to a rotatable element at a distal end of the manipulator arm.

A drape includes a first drape portion configured to receive a manipulator arm of a surgical system and a pocket coupled to a distal portion of the first drape portion. The pocket is configured to receive a manipulator of the surgical system. The pocket includes a flexible membrane positionable between an output of the manipulator and an input of a surgical instrument mountable to the manipulator. In some embodiments, the flexible membrane is located at a distal end of the pocket. In some embodiments, the flexible membrane is configured to allow an actuating force to be transmitted from the output of the manipulator to the input of the surgical instrument. In some embodiments, the pocket provides a sterile barrier between the manipulator and the surgical instrument. In some embodiments, the drape further includes a rotatable seal configured to couple a proximal opening of the pocket to the first drape portion.

An electromagnetic device includes a jig and multiple wires. The jig includes a center member and coil-separating blocks. The coil-separating blocks protrude from the center member and are separated from each other to provide a coil channels. Each of the wires is wrapped on the jig, around the center member, and in one of the coil channels to form one of a multiple coils. Each of the coils is configured to connect to an electromagnetic navigation system and generate respective electromagnetic fields to be emitted relative to a subject.

An entry guide tube and cannula assembly, a surgical system including the assembly, and a method of surgical instrument insertion are provided. In one embodiment, the assembly includes a cannula having a proximal portion that operably couples to an accessory clamp of a manipulator arm, and a distal tubular member coupled to the proximal portion, the tubular member having an opening for passage of at least one instrument shaft. The assembly also includes an entry guide tube rotatably coupled to the proximal portion of the cannula, the entry guide tube including a plurality of channels for passage of a plurality of instrument shafts, wherein the entry guide tube is rotatably driven relative to the proximal portion of the cannula by rotation of at least one instrument shaft about a longitudinal axis of the entry guide tube.

A hand-held antenna system allows medical personnel to ascertain the presence or absence of objects (e.g., medical supplies) tagged with transponders in an environment in which medical procedures are performed. In use, the hand-held antenna system may be positioned proximate a patient at a time after a medical procedure, such as after child birth, so the system can scan the patient's body to determine the presence of objects tagged with transponders. The antenna system includes three antenna elements arranged mutually orthogonal to each other to transmit and receive signals in three coordinate directions. A controller is coupled to the antenna elements to transmit signals to the transponders and to receive response signals. The antenna system may operate in a static scan mode wherein the antenna system is held in a fixed position by a user and a dynamic scan mode wherein the antenna system is moved by a user.

Systems and methods for mitigating constraints associated with wireless power transmission in applications where the position and orientation of the desired magnetic field changes over time, for example, because the position and orientation of the receiver being powered changes over time or because different receivers having different positions and orientations are being powered at different times. In accordance with some embodiments, the system employs a plurality of wireless power transmitters in a defined space, each transmitter consisting of individual coils oriented orthogonally relative to each other. Using field interference amongst these individual coils as well as amongst the transmitters they form, one can actively control the wireless power field intensity and orientation at any given point in the defined space. This allows for methods to steer the power transmission towards a specific target at a specific angle.

An augmented reality/virtual reality (AR/VR) system employs a tracking system for tracking one or more components of the AR/VR system using a generated electromagnetic (EM) field. The tracking system employs an EM coil for generating the EM field or, alternatively, sensing the EM field. The EM coil includes a core substrate and thin metal foil wrapped around the core substrate in three orthogonal axes. The EM coil is effectively hollow in that it weighs less than a conventional solid ferrite or ferrous core of comparable dimensions, either through the use of one or more openings formed in the core substrate, the use of a material less dense than ferrite or ferrous materials, the formation of the core substrate as a hollow framework, or a combination thereof. The resulting EM coil thus weighs less than conventional solid-core EM coils, thereby reducing user fatigue and the possibility of misalignment of the EM coil as a result from a drop impact of the device implementing the EM coil.

A ground protection coil for insertion into a circuit includes an inner coil section consisting of a wire wound in a first direction for a first number of turns and an outer coil section consisting of the wire wound in a second direction for a second number of turns. The second direction is at an angle of approximately 90 degrees from the first direction.
