Expandable intervertebral implant
An implant for therapeutically separating bones of a joint has two endplates each having an opening through the endplate, and at least one ramped surface on a side opposite a bone engaging side. A frame is slideably connected to the endplates to enable the endplates to move relative to each other at an angle with respect to the longitudinal axis of the implant, in sliding connection with the frame. An actuator screw is rotatably connected to the frame. A carriage forms an open area aligned with the openings in the endplates. The openings in the endplates pass through the carriage to form an unimpeded passage from bone to bone of the joint. The carriage has ramps which mate with the ramped surfaces of the endplates, wherein when the carriage is moved by rotation of the actuator screw, the endplates move closer or farther apart.
EXPANDABLE IMPLANT
An expandable implant for inserting within a skeletal space is provided, and a method for using the implant to expand the skeletal space. The implant is preferably designed to be inserted into an intervertebral space to replace at least part of an intervertebral disc between adjacent vertebral bodies. The expandable implant contains at least one first expansion compartment and at least one second expansion compartments, which compartments can be inflatable balloons that are inflated by a catheter. Inflating the first expansion compartment expands the implant in a first direction and inflating the second expansion compartment expands the implant in a second direction.

Spinal fusion cage system with inserter
A bone graft delivery system and method for using same to deliver graft material into a surgical site. The system includes an interbody implant having a securing site disposed on a surface of the implant and a holder having an elongated, hollow handle including a distal end. The distal end of the holder is configured to removably engage the securing site of the interbody implant to secure the interbody implant to the distal end of the holder until such time as a user desires to disengage the holder from the interbody implant. The interbody implant may be a cage implant having opposing anterior and posterior surfaces, opposing first and second lateral surfaces, and opposing top and bottom surfaces, wherein the top surface comprises a first aperture and the bottom surface comprises a second aperture, the posterior surface comprising a third aperture, the first, second, and third apertures all linking to a main cavity, the main cavity generally extending between the top surface and the bottom surface.

Medical devices for use along the biliary and/or pancreatic tract
Medical devices and method for making and using the same are disclosed. An example medical device may include implantable medical device for use along the biliary and/or pancreatic tract. The implantable medical device may include a tubular member having a first end configured to be disposed within the duodenum of a patient and a second end configured to be disposed adjacent to a pancreatic duct and/or bile duct. The tubular member may have a body including one or more wire filaments that are woven together. The tubular member may also have an outer surface with a longitudinal channel formed therein.

DEVICE FOR EXPANDING AND SUPPORTING BODY TISSUE
An expandable device for expanding and supporting body tissue comprises an inferior endplate having an outer surface configured to contact one body tissue surface and a superior endplate having an outer surface configured to contact an opposing body tissue surface. The inferior endplate and the superior endplate are movable relative to each other in a direction of expansion. The device includes an elevator captively supported between the inferior endplate and the superior endplate for independent movement along the direction of expansion. In the first direction the elevator is moved toward said superior endplate to lift the superior endplate and expand the device. In the second direction the elevator moves away from said superior endplate toward said inferior endplate to create a space for insertion of an insert into the expanded device.
