Abstract
An implantable device includes a barrel. The barrel has a first portion and a second portion. The implantable device includes a first plate having multiple projections extending from one side of the first plate, where the first plate is configured to movably couple to the first portion of the barrel. The implantable device includes a second plate having multiple projections extending from one side of the second plate, where the second plate is configured to movably couple to the second portion of the barrel. The barrel is configured to transition from a collapsed form having a first height to an expanded form having a second height, where the second height is greater than the first height.
Claims20
A method of surgically stabilizing adjacent vertebral bodies, said method comprising:
- providing an implantable device, the implantable device including:
- a barrel;
- a first plate having multiple projections extending from the first plate, the first plate configured to movably couple to the barrel;
- and
- a second plate having multiple projections extending from the second plate, the second plate configured to movably couple to the barrel,
- wherein the barrel is configured to transition from a collapsed form having a first height to an expanded form having a second height, wherein the barrel comprises a first endplate, a second endplate, an actuator positioned between the first endplate and the second endplate, wherein the actuator includes a first ramp and a second ramp for abutting one of either the first end plate or the second endplate to cause expansion of the barrel,
- wherein the first and second plates are configured to move independently of each other;
- inserting the implantable device into an interspinous space between the adjacent vertebral bodies;
- and
- expanding the barrel from the first height to the second height using the actuator.
A method of surgically stabilizing adjacent vertebral bodies, said method comprising:
- providing an implantable device, the implantable device including:
- a barrel having a first portion and a second portion;
- a first plate shaped in a lordotic profile movably coupled to the barrel, wherein the first plate is capable of angulating relative to the first portion of the barrel;
- and
- a second plate shaped in a lordotic profile movably coupled to the barrel,
- wherein the second plate is capable of angulating relative to the second portion of the barrel,
- wherein the barrel is configured to transition from a collapsed form having
- a first height to an expanded form having a second height, wherein the barrel comprises a first endplate, a second endplate, an actuator positioned between the first endplate and the second endplate, wherein the actuator includes a first ramp and a second ramp for abutting one of either the first endplate or the second endplate to cause expansion of the barrel,
- wherein the first and second plates are configured to move independently of each other.
- inserting the implantable device into an interspinous space between the adjacent vertebral bodies;
- and
- expanding the barrel from the first height to the second height using the actuator.
