초록 ▼

An oblique expanding fusion cage device including a body with a superior portion and an inferior portion. The superior portion and the inferior portion have a proximal end and a distal end. The fusion cage device also includes a pathway, an opening, and an expanding member. The pathway travels from the proximal end to the distal end of the device between the superior and inferior portions. The opening in the proximal end of the body enables access to the pathway. The expanding member may be removably inserted into the opening and is moveable toward the distal end of the body, wherein the expanding member engages the superior portion and the inferior portion as the expanding member moves distally within the pathway.

대표청구항 ▼

1. An oblique expanding fusion cage device, comprising: a body with a superior portion and an inferior portion, wherein the superior portion and the inferior portion each have a proximal end and a distal end, the inferior portion comprises at least one protrusion extending toward the superior portion, and the superior portion comprises at least one opening adapted to receive the at least one protrusion, wherein the superior portion has an interior portion with a semicircular cross-sectional shape and the inferior portion has an interior portion with a semicircular cross-sectional shape, and wherein at least a portion of the interior portion of the superior portion overlaps with at least a portion of the interior portion of the inferior portion, the superior portion having a planar contact surface and the inferior portion having a planar contact surface for engaging vertebrae;a pathway extending from the proximal end of the body to the distal end of the body between the superior portion and inferior portion;an opening in the proximal end of the body enabling access to the pathway; andan expanding member removably inserted into the opening and moveable toward the distal end of the body, wherein the expanding member engages the superior portion and the inferior portion as the expanding member moves distally within the pathway. 2. The oblique expanding fusion cage device of claim 1, wherein the at least one opening includes teeth and the at least one protrusion includes engagement tabs adapted to engage the teeth in the at least one opening. 3. The oblique expanding fusion cage device of claim 1, wherein the pathway extends through the at least one protrusion. 4. The oblique expanding fusion cage device of claim 1, wherein a width of the passageway is equal to or greater than a diameter of the expanding member. 5. The oblique expanding fusion cage device of claim 1, wherein the pathway is threaded and the expanding member includes threading that engages with the pathway threading. 6. The oblique expanding fusion cage device of claim 1, wherein the opening includes a locking mechanism for locking the expanding member when fully inserted in the device. 7. The oblique expanding fusion cage device of claim 1, wherein the fusion cage device has a trapezoidal shape in an expanded position. 8. An oblique expanding fusion cage device, comprising: a body with a superior portion and an inferior portion, wherein the superior portion and the inferior portion each have a proximal end and a distal end;a pathway extending from the proximal end of the body to the distal end of the body and extending through the inferior portion;an opening in the proximal end of the body enabling access to the pathway;a trapezoidal deployment portion located in the distal end of the pathway, wherein the deployment portion expands in a unilateral direction; andan expanding member removably inserted into the opening and moveable toward the distal end of the body, wherein the expanding member engages the deployment portion and moves the deployment portion from a parallel orientation to a perpendicular orientation. 9. The oblique expanding fusion cage device of claim 8, wherein the deployment portion is hingedly coupled to the distal end of the superior portion. 10. The oblique expanding fusion cage device of claim 8, wherein the pathway is threaded and the expanding member includes threading that engages with the pathway threading. 11. An oblique expanding fusion cage device, comprising: a first arm and a second arm, each arm having a proximal end and a distal end;an expanding member positioned between the first arm and the second arm, the expanding member comprising a body portion at the proximal end and a wedge portion at the distal end, wherein the proximal end of the first arm is pivotally coupled to the body portion with a first pivot pin, and wherein the proximal end of the second arm is pivotally coupled to the body portion with a second pivot pin;a winding mechanism located at the proximal end of the device, the winding mechanism including a cable extending between the winding mechanism and the wedge and adapted for pulling the wedge towards the proximal end of the device.
