Delivery systems and methods for delivering a material to a target site. A delivery instrument is coupled to a robotic manipulator and includes a delivery device with a distal tip having an opening to deliver the material to the target site. Controller(s) obtain a virtual model of the target site and a virtual boundary associated with the virtual model. The controller(s) register, using a navigation system, the virtual model and the virtual boundary to the target site and control the robotic manipulator to move the distal tip of the delivery device with respect to the target site. The controller(s) detect that distal tip of the delivery device either is, or will, interact with the virtual boundary, and in response, control the robotic manipulator to move the distal tip away from the virtual boundary.

Delivery system and method for delivering material to a target site during a medical procedure

A delivery system and methods are disclosed for delivering a material to a target site. A delivery instrument is coupled to a robotic manipulator and comprises a delivery device having a distal tip comprising an opening deliver the material to the target site through the opening. A navigation system tracks the delivery device and the target site and generates position signals. One or more controllers are in communication with the robotic manipulator and the navigation system and define a virtual boundary associated with the target site, wherein the virtual boundary is utilized to constrain movement of the delivery device. The one or more controllers control one or more joint motors of the robotic manipulator to move the distal tip of the delivery device with respect to the virtual boundary based on the position signals from the navigation system.

Methods of removing tissue from a patient during a surgical procedure, such as for preparing a spine of a patient to receive an implant during a fusion procedure. A working portion of an instrument is moved with actuators relative to a hand-held portion in at least three degrees of freedom including pivoting in pitch and yaw about a pivot. The working portion is translated while the hand-held portion is manually grasped and moved during the surgical procedure. The working portion is rotated with a drive mechanism to remove a volume of the tissue of the patient with a cutting accessory of the working portion. The actuators may move the working portion to substantially maintain the cutting accessory in a desired relationship to a virtual boundary defining the volume of the tissue to be removed. A position of the cutting accessory relative to the virtual boundary may be determined and tracked.

A method of assembling an implantable electrode array from a coupon () formed from plastically deformable material. Layers of material are disposed on the coupon to form the electrodes () and conductors () of one or more electrode arrays. Sections of the coupon on which the electrodes and conductors are removed, along with the electrodes and conductors to form the electrode arrays. The removed sections of the coupon thus function as plastically deformable carriers () for the arrays ().

Plural medical device formed from one or more layers of thin film polymer are assembled from a single polymer coupon. Initially the coupon is bonded to a rigid substrate. Force, heat and a suction are selectively applied to the coupon to ensure that it has a consistent height across its exposed surface. Once the polymer coupon is bonded the components forming the medical device are attached to the coupon and the coupon is shaped to form the individual medical devices. Shaped sections of the coupon are then lifted off the rigid backing. The lifted off sections on which the components were attached are the medical devices.

Delivery systems include a delivery instrument and a delivery device removably attached to the delivery instrument. A plurality of actuators are operable to position an opening of the delivery device with respect to the target site. A material supply system supplies the material to the delivery device. A navigation system tracks the target site and the opening as the target site moves during the procedure and as the opening moves during the procedure. A controller controls movement of the opening and/or flow rate of the material to achieve desired delivery of the material at the target site using various methods.

An electrode array with a flexible array substrate on which plural spaced apart electrodes are disposed. Integrated circuits are disposed in the array substrate. The integrated circuits are mounted to package substrates. The package substrates are more rigid than the array substrate. Internal to each package substrate is at least one electrical conductor. The electrical conductor extends from a bond pad integral with integrated circuit at least partially through the package substrate. The electrical conductor functions as the conductive member that extends between the integrated circuit an electrode with which the integrated circuit is associated.

A sensor assembly comprises a base plate and a sensor member displaceable relative to the base plate. A spring arrangement operates in first and second stages in response to displacement of the sensor member relative to the base plate. Different resolutions of force and torque measurements are associated with the first and second stages. A light sensitive transducer senses displacement of the sensor member relative to the base plate and generates corresponding output signals. A collimator directs a plurality of light beams onto the light sensitive transducer so that the light beams strike different pixels of the light sensitive transducer to sense displacement of the sensor member relative to the base plate.

A method of forming an implantable electrode array that includes one or more packaged control modules. A control module is packaged by mounting the module to a substrate and forming a containment ring around the module. A conformal coating is disposed over the surface of the module to cover the carrier. Within the containment ring, the conformal coating hardens to form a non-porous shell around the control module. The one or more packaged control modules are placed in a flexible array. Electrodes that are mounted to or embedded in the flexible carrier are connected to the one or more control modules.

An electrode array assembly with a frame that is foldable or bendable on which electrodes are disposed. The frame includes laterally spaced apart bridges. Tabs extend laterally outwardly from the bridges Electrodes are disposed on the tabs. Beams, also part of the frame, extend between the laterally adjacent bridges. The frame can be folded around the beams so as to cause the laterally spaced bridges to at least partially overlap. When the beams are so bent, the electrode array can be disposed in an access cannula that has a diameter less than the width of the unfolded array.

An implantable electrode array that includes a carrier on which multiple spaced apart electrodes are disposed. Embedded in the module are control modules. The control modules are contained in packages. Portions of the packages extend outwardly from the carrier so as to be disposed against adjacent surfaces of the carrier. The packages contain conductive tracts that provide conductive links from the conductors internal to the carrier to the packaged control modules.

A method for repairing focal defects in tissue of a patient using an instrument having a cutting tip and a drive motor for rotating the cutting tip includes the steps of receiving a virtual three-dimensional model of a bone created from scan data of the bone wherein the bone has a focal defect, creating a three-dimensional shape of a target volume of material to be removed from the bone, removing the target volume of the material from the bone with the cutting tip, and placing an implant into the bone to repair the focal defect.
