Catholic Healthcare West (CHW) - Phoenix AZ

International Classification:

A61B 17/56
G06F 19/00
G06F 17/50
G06G 7/48

US Classification:

606 86 R, 700 97, 703 6

Abstract:

A system for planning a spine surgery, comprising a haptic interface capable of providing force feedback to the user and a computer adapted to simulate a surgical procedure by responding to inputs from the haptic interface and outputting haptic feedback to the haptic interface is provided.The system further comprising a rapid prototyping unit including a unit that is adapted to create models of the anatomical region where the surgical procedure will be performed in its current unoperated condition and in the predicted postoperative condition. Further the rapid prototyping unit is adapted to create a three dimensional guide to be used in the surgical procedure as well as suggest revisions to the surgical procedure. The system further comprises a computer that simulates loading of the spine and planned implanted hardware using finite element software.

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

An implantable device assembly including a bone fusion cage assembly having first and second housing members and a biasing member. The first housing member defines a first contact surface. The second housing member defines a second contact surface that faces generally opposite the first contact surface. The biasing member is operable to bias the first and second housing members away from each other into an expanded position. Each of the first and second housing members may include at least one pivot portion that defines the contact surfaces. The implantable device assembly may also include a plate assembly that is mounted to the bone fusion cage assembly.

International Classification:

A61B 17/86

US Classification:

606304

Abstract:

A cannulated and possibly fenestrated device for injection of material into bone can be dangerous because large, uncontrolled pressures are introduced during injection into a somewhat closed system, and material may extrude undesirably or emboli may be introduced. Methods and devices are described for providing venting of pressure upon injection of material through cannulated and possibly fenestrated screws. The first method involves a bone screw and/or anchor device that includes multiple channels to allow material to flow in through one channel and out through another channel. The second method involves a plunger that can force material into bone if advanced or lessen pressure if withdrawn. The third method involves usage of two separate screws. Material is alternately injected or withdrawn from each screw to cause material to flow from one screw to the other in a controlled way that creates a uniform or asymmetrical distribution of material as desired.

Abstract:

System and method for automatically bending a surgical rod are provided. The system includes a linear movement device configured to axially feed the surgical rod, a rotational movement device configured to rotate the surgical rod as it is axially fed, and a bending device including a roller to impose bending forces against the rod. The rod is free from contact with the bending device after it is axially fed past the roller.
