The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

Apparatus and methods for treatment of a bone. The apparatus may include a mesh anchoring substrate extending longitudinally between a base and a hub. The base may have a base first end adjacent the mesh, a base second end opposite the base first end, and a cannula extending through the base. The apparatus may include a support. The support may include an elongated body extending between an end of the support and a flange. The end of the support may be configured to be removably coupled to a coupling mechanism in the hub. The flange may be configured for being seated outside the base against the base second end. A maximum circumference of the elongated body may be not greater than a cannula circumference.

A composite comprising: a barrier, said barrier being configured to selectively pass water, and said barrier being degradable in the presence of water; a matrix material for disposition within said barrier, wherein said matrix material has a flowable state and a set state, and wherein said matrix material is degradable in the presence of water; and at least one reinforcing element for disposition within said barrier and integration with said matrix material, wherein said at least one reinforcing element is degradable in the presence of water, and further wherein, upon the degradation of said at least one reinforcing element in the presence of water, provides an agent for modulating the degradation rate of said matrix material in the presence of water.

A composite implant comprising an injectable matrix material which is flowable and settable, and at least one reinforcing element for integration with the injectable matrix material, the at least one reinforcing element adding sufficient strength to the injectable matrix material such that when the composite implant is disposed in a cavity in a bone, the composite implant supports the bone.

A method for treating a bone, the method comprising: selecting at least one reinforcing element to be combined with an injectable matrix material so as to together form a composite implant capable of supporting the bone; positioning the at least one reinforcing element in a cavity in the bone; flowing the injectable matrix material into the cavity in the bone so that the injectable matrix material interfaces with the at least one reinforcing element; and transforming the injectable matrix material from a flowable state to a non-flowable state so as to establish a static structure for the composite implant, such that the composite implant supports the adjacent bone.

Systems and methods for treating conditions and diseases of the spine are disclosed herein. A device includes a balloon catheter comprising at least one inner lumen incorporated within an elongated shaft; a distal end having an inner balloon positioned inside and completely surrounded by an outer balloon; and a proximal end having an adapter for passage of at least one of an inflation fluid or a medical instrument; and an optical fiber comprising an outer diameter sized to pass through the inner lumen of the elongated shaft; a nonlinear light-emitting portion of a given length, wherein a portion of a cladding material from the nonlinear light-emitting portion has been removed so that light energy may be emitted along the length of the nonlinear light-emitting portion; and a linear elongated portion for guiding light towards the nonlinear light-emitting portion.

A graft material injector device and method are disclosed. The injector device includes an elongated injector tube and a side loading aperture for receiving graft material. A graft material loader and a cover for the side loading aperture may optionally be included.

An implantable orthopedic support device and methods of using the device are disclosed. The device can have rigid structural components that can translate longitudinally with respect to each other, and in so doing can change the vertical height of the device. The structural components can be driven by a drivescrew mechanism to change the vertical height of the device.

A method of changing a bone angle includes creating an osteotomy between a first portion and a second portion of a tibia of a patient; creating a cavity in the tibia by removing bone material along an axis extending in a substantially longitudinal direction from a first point at the tibial plateau to a second point; placing a non-invasively adjustable implant into the cavity, the non-invasively adjustable implant comprising an adjustable actuator having an outer housing and an inner shaft, telescopically disposed in the outer housing, and a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; coupling one of the outer housing or the inner shaft to the first portion of the tibia; coupling the other of the outer housing or the inner shaft to the second portion of the tibia; and remotely operating the driving element to telescopically displace the inner shaft in relation to the outer housing, thus changing an angle between the first portion and second portion of the tibia.

The present invention provides a spinal implant structure. The spinal implant structure comprises a first tube, a second tube and at least one expansion arm. The second tube is disposed on the horizontal orientation of the first tube and does not overlap with the first tube. The diameter of the first tube is larger than that of the second tube. One end of the expansion arm is connected to the first tube, and the other end of the expansion arm is free end. The expansion arm and the first tube create an angle. The expansion arm includes a supporting arm. One end of the supporting arm is connected to the expansion arm, and the other end of the supporting arm is connected the second tube. The support arm, in response to a change in a distance between the first tube and the second tube, drives the expansion arm to move, thereby increasing the included angle and expanding the spinal implant structure.

Disclosed is a medical device having a first implant portion having a proximal end, a second implant portion connected to the first implant portion, the second implant portion having a distal end, and a driver assembly removably connected to the distal end, the driver assembly comprising a drill connected to the distal end at a connection.
