Abstract
An implantable device may comprise a barrel, the barrel having an upper portion and a lower portion. The barrel may be configured to transition from a collapsed form having a first height to an expanded form having a second height and wherein the second height is greater than the first height. The implantable device may further include an actuator assembly disposed in the barrel, the actuator assembly comprising a front ramped actuator in engagement with the barrel, a rear ramped actuator in engagement with the barrel, and a central screw that extends from the rear ramped actuator through the front ramped actuator. The implantable device may further comprise a first plate and a second plate.
Claims20
An implantable device, comprising:
- a barrel, the barrel having an upper portion and a lower portion;
- an actuator assembly disposed in the barrel, the actuator assembly comprising a front ramped actuator in engagement with the barrel, a rear ramped actuator in engagement with the barrel, and a central screw that extends from the rear ramped actuator through the front ramped actuator;
- a first plate, formed integrally with the barrel, comprising a first portion that extends from the upper portion, a second portion that extends form the lower portion, and a first spike assembly disposed in the first plate, the first spike assembly comprising one or more projections extending from a first side of the first plate;
- and
- a second plate having multiple projections extending from a first side of the second plate, the second plate configured to be received on the central screw;
- wherein the barrel is configured to transition from a collapsed form having a first height to an expanded form having a second height and wherein the second height is greater than the first height.

- a barrel, the barrel having an upper portion and a lower portion;
- an actuator assembly disposed in the barrel;
- a first plate, formed integrally with the barrel, comprising a first portion that extends from the upper portion, a second portion that extends form the lower portion, and a first spike assembly disposed in the first plate, the first spike assembly comprising one or more projections extending from a first side of the first plate;
- and
- a locking plate having multiple projections extending from a first side of the locking plate, the locking plate configured to be received on a central screw disposed in the actuator assembly;
- wherein the actuator assembly is configured to move the barrel from a collapsed form a first height to an expanded form having a second height.
