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.

A surgical sagittal saw for use with a complementary blade assembly that includes a static bar. The saw includes a head over which the blade assembly bar is seated. A coupling rod is able to be mounted to the head to move along the longitudinal axis of the rod. The coupling rod has a head that, as result of the longitudinal movement of the rod is moved towards and away from the head. A blade assembly may be disposed on the saw head adjacent the coupling rod. The coupling rod can be positioned in a run state so that the rod head abuts the bar of the blade assembly so as to hold the blade assembly to the saw head. Alternatively, the coupling rod can be repositioned in a load state the rod head is spaced from the saw head. This allows the blade assembly to be removed and replaced.

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.

A cutting system including a surgical saw and a blade assembly is described. The blade assembly may comprising a blade bar, a blade head, and a tag. The tag may comprise a memory containing data related to one or more characteristics of the blade assembly. The surgical saw may comprise a saw processor for receiving data from the tag of the blade assembly and be configured to regulate the operation of the saw based on the one or more characteristics of the blade assembly. The one or more characteristic of the blade assembly comprises may comprise a blade assembly length, a blade geometry, and a blade teeth geometry. A method of navigating a surgical saw is also described. The method may comprise attaching a blade to the saw, touching a pointer to reference points on the blade, and determining the position and orientation of a distal end of the blade.

The saw blade comprising a bar and a blade. The distal end of the bar formed with a distal end opening and a discharge port formed in at least one of the top and bottom faces that opens into the distal end opening, the discharge port for discharging debris. The bar is formed with a geometric feature for receiving a coupling member to hold the bar to the saw, the geometric feature being an opening that extends through the bar. The blade having a blade base disposed in the distal end opening of the bar and a blade crown that extends forward from the blade base and forward of the distal end of the bar.

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.
