  • Publication number: 20130325066
    Abstract: Medical devices and related methods for the treatment of spinal conditions are described herein. In one embodiment, a method includes disposing at least a portion of a support member into a space between adjacent spinous processes. The support member defines a lumen between a proximal end and a distal end of the support member. An expandable member is inserted through the lumen of the support member such that a distal end portion of the expandable member is disposed outside a distal end of the lumen and a proximal end portion of the expandable member is disposed outside a proximal end of the lumen. The distal end portion and the proximal end portion of the expandable member are then expanded such that each of the distal end portion and the proximal end portion of the expandable member has an outer diameter greater than an outer diameter of the support member.

  • Patent number: 8157841
    Abstract: A method includes inserting an implant having a support member and a retention member movably coupled to the support member such that at least a portion of the support member of the implant is disposed between a first spinous process and a second spinous process. The implant is rotated relative to the first spinous process and the second spinous process about an axis substantially normal to a mid-line axis of a spinal column while the portion of the support member is disposed between the first spinous process and the second spinous process. In some embodiments, the implant is rotated such that an inner surface of an end portion of the retention member is between an outer surface of the end portion of the retention member and the first spinous process. The retention member is translated relative to the support member.

  • Patent number: 8097018
    Abstract: An apparatus includes a support member having an outer surface configured to be disposed between adjacent spinous processes and a retention member rotatably coupled to the support member. A first end portion of the retention member is spaced apart from the outer surface by a first distance along an axis substantially normal to a longitudinal axis of the support member when the outer surface is disposed between the adjacent spinous processes. A second end portion of the retention member is spaced apart from the outer surface by a second distance along the axis substantially normal to the longitudinal axis when the outer surface is disposed between the adjacent spinous processes. The first end portion of the retention member and the second end portion of the retention member are configured to cooperatively limit movement of the support member relative to the adjacent spinous processes.

  • Patent number: 8057513
    Abstract: Spinal implants and methods for performing surgical procedures on the spine are describe herein. In one embodiment, for example, a method includes percutaneously inserting into a body an expandable member having a first configuration, a second configuration and a third configuration. The expandable member includes a support portion and a retention portion. The support portion has a longitudinal axis and is configured to be disposed between adjacent spinous processes. The retention portion is configured to limit movement of the support portion along the longitudinal axis. When the expandable member is in the first configuration, it is disposed in a first location between the adjacent spinous processes. The expandable member is then expanded from the first configuration to the second configuration. The expandable member is then contracted from the second configuration to the third configuration and disposed in a second location, the second location being different from the first location.
