1. A method for implanting a medical device, comprising:
- forming at least one cut in a portion of a vertebra of a patient'"'"'s spine to separate the vertebra into at least two halves; and
positioning opposed ends of an elongate body between two halves of the vertebra to enlarge a spinal canal formed within the vertebra such that a slot-free anterior side is positioned adjacent to the spinal canal and a plurality of elongate slots formed in cephalad, caudal, and posterior sides of the elongate body are positioned away from the spinal canal.

Abstract
A medical implant device for use in spinal surgery, and more preferably for use in laminoplasty surgery is provided. The implant is a cage-like member having a generally hollow, elongate body with open ends. The implant is formed from a generally hollow, elongate body having four sides: opposed cephalad and caudal sides, and opposed posterior and anterior sides adjacent to the cephalad and caudal sides. The four sides extend along a longitudinal axis, and define an inner lumen extending between opposed first and second open ends.

13. A method for implanting a medical device, comprising:
-
cutting a spinous process in a patient'"'"'s vertebra to form a bisected spinous process having two halves; separating the two halves of the bisected spinous process; and positioning an elongate body between the two halves of the bisected spinous process to enlarge a spinal canal formed within the vertebra and to position a spinous process replacement member extending outward from the elongate body at a location in which the spinous process replacement member mimics the spinous process before it is bisected. - View Dependent Claims (14, 15)

16. A method for implanting a medical device, comprising:
-
cutting a lamina in a patient'"'"'s vertebra such that a spinous process and a spinous articular process of the vertebra are separated from one another; and positioning an elongate body between the separated spinous process and spinous articular process such that a fixation element receiving member extending outward from a first end of the elongate body is positioned adjacent to the a posterior side of the spinous articular process, and an extension member formed on the elongate body and opposed to the fixation element receiving member is positioned adjacent to an anterior side of the spinous articular process; passing at least one suture through at least one slot formed in the elongate body such that the at least one suture is positioned within at least one suture-receiving recess formed in the at least one slot; and attaching the at least one suture to bone adjacent to the elongate body to anchor the elongate body to the vertebra. - View Dependent Claims (17, 18, 19, 20, 21, 22)
