An expandable implant for bone restoration. The implant includes a first end element and a second end element. A plate is expandable in a first direction, and a blade expandable in a second direction. A first interconnecting element extends between the plate and at least one of the first and second end elements. A second interconnecting element extends between the blade and at least one of the first and second end elements. When the implant is in a collapsed position, a length of the blade is substantially parallel to the longitudinal axis, and when the blade is in an expanded position, the length of the blade is non-parallel to the longitudinal axis. The blade may include a length extending from a base to a tip, and the tip of the blade is further from the longitudinal axis than the plate when the implant is in the expanded position.

A kyphoplasty cannula includes a shaft extending between opposite first and second end surfaces. The shaft has an inner surface defining a lumen. The shaft has a first opening that extends through the first end surface and a second opening that extends through the second end surface. A scoop extends from the second end surface. The scoop has an arcuate inner surface that is continuous with the inner surface of the shaft an opposite outer surface. The scoop has a rib. Kits and methods of use are disclosed.

An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. A method of repairing tissue is also disclosed. The device and method can be used to treat compression fractures. The compression fractures can be in the spine. The device can be deployed by compressing the device longitudinally resulting in radial expansion.

A device is disclosed for reducing a vertebral compression fracture, comprising a superior end plate and an inferior end plate disposed along a vertical axis. The superior end plate and the inferior end plate are slidably separable in a vertical direction along the vertical axis. An interior chamber is provided in fluid communication with a port extending from an exterior to the interior chamber. The device is deployable within a vertebral body and expandable within the vertebral body by injecting a flowable material into the interior chamber thereby displacing the superior and inferior end plates along the vertical axis.

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.

A surgical expandable implant includes a bolt, a movable member, and a support body. The bolt has a bolt body and a fixing member. The movable member is configured to be slidably sleeved on the bolt body. The support body has a first end configured to extend through the fixing member and a second end configured to extend through the movable member. The movable member is configured to slide along the length of the bolt body so as to move the support body from an initial shape to a deformed shape.

A method of using a robotic guidance system for performing surgery on a spine is provided. The method includes utilizing a computerized tomographic scan image of a location on a spinal column of a patient, such that the computerized tomographic scan image is connected to a computer and visible on a monitor connected to the computer. The method also includes attaching a coupling component to the spinal column of the patient, coupling a marker to the coupling component, and imaging, with a fluoroscope, the view of the spinal column of the patient, wherein the fluoroscope image is transmitted to the computer and visible on the monitor and the at marker is clearly visible in the fluoroscope image. The method also includes positioning a cannula, with a robotic mechanism, to a first position relative to a vertebra in the spinal column of the patient, drilling a passage through the cannula into bone of the vertebra in the spinal column of the patient, inserting a guidewire through the cannula into the passage in the bone of the vertebra in the spinal column of the patient, and positioning a screw into the bone of the vertebra in the spinal column of the patient.

An adjustable balloon that includes a handle having an inflation port, an access cannula, a rotary handle, an inner sleeve and sharp tip. The inner sleeve extends within the access cannula to support compliant, inflatable structure. The access cannula may be retracted into the handle by operation of the rotary handle to expose the inflatable structure, such that the inflatable structure may have an adjustable length. The access cannula may include length indicators to show a length of the inflatable structure as a result of the access cannula being withdrawn into the handle.

A trumpet expandable vertebral device, includes: a center shaft having a front end and a rear end; a trumpet expandable part mounted outside and surrounding the center shaft, wherein the trumpet expandable part includes: plural expandable plates, each expandable plate having a thickness which increases from the front end toward the rear end; a fixed part, for fixing the relative position of the trumpet expandable part with respect to the center shaft in an axial direction of the center shaft, but allowing the center shaft to rotate with respect to the trumpet expandable part within the fixed part in a radial direction of the center shaft; and a connection part for connecting the trumpet expandable plates with the fixed part; a trumpet expanding ring mounted outside and surrounding the center shaft, wherein the trumpet expanding ring is located between the center shaft and the trumpet expandable part in the radial direction; wherein when the trumpet expanding ring moves toward the rear end relatively to the trumpet expandable part, the trumpet expandable plates are expanded to expand a vertebra.

An expandable vertebral device with triangular connection beam includes: a rotatable center shaft; a fixed part, wherein the rotatable center shaft penetrates through the fixed part and is rotatable relative to the fixed part; a movable slide, surrounding a portion of the rotatable center shaft, and is movable along an axial direction of the rotatable center shaft in response to a rotation of the rotatable center shaft; at least one first connection beam, which is rotatably connected to the fixed part; at least one second connection beam, which is rotatably connected to the movable slide, and is rotatably connected to the corresponding first connection beam; whereby when the rotatable center shaft rotates within the fixed part so that the movable slide moves away from the fixed part, the first and second connection beams are expanded to restore a vertebra to its original shape.
