Abstract:
1. Apparatus for interspinous distraction, comprising: a wire configured for insertion between two adjacent spinous processes of a patient; a dilator component insertable coaxially over the wire and configured for dilating a passage from an insertion point on the patient to a space between the two adjacent spinous processes; a first thin-walled access sheath having an internal lumen insertable coaxially over the dilator component; a distractor device insertable through the internal lumen of the first access sheath to distract the space between the two adjacent spinous processes; an implant device, including: a first implant component having a midsection sized and configured for insertion between the two adjacent spinous processes of a patient, the midsection having a through lumen insertable over the wire, and a flange-shaped first outer section attached at a first end of the midsection, the first outer section having a first medial surface with a first means to contact and engage thick, bony portions of the spinous processes; a second implant component having a flange-shaped second outer section, the second outer section each having a second medial surface with a second means to contact and engage thick, bony portions of the adjacent spinous processes; and attachment means for attaching the flange-shaped second outer section to a second end of the midsection of the first implant component.
