Abstract:
1. An interspinous implant device for distracting between spinous processes, said device comprising: a main body including a first shaft having a longitudinal axis; a second shaft having a longitudinal axis; a first clamping mechanism having first and second jaws configured to clamp a spinous process of a first vertebra; a second clamping mechanism having third and fourth jaws configured to clamp a spinous process of a second vertebra; said first, second, third and fourth jaws extending transversely from said main body, each of said first, second, third and fourth jaws comprising a first end and a second end, respectively, said first and second ends being opposite one another along a transverse direction when said jaws extend transversely from said main body, wherein at least two of said jaws are releasably mountable at said first end thereof, respectively, to said first shaft independently of the jaw that each of said at least two of said jaws forms one of the clamping mechanisms with, respectively, and are mountable to and removable from said shaft by relative movement between said respective jaw and said shaft in a direction normal to a longitudinal axis of said first shaft; said second shaft being mountable to at least two other of said jaws at distal end portions thereof, so that said second shaft is mountable on a side of the spinal processes that is opposite a side of the spinal processes that said first shaft is mountable on wherein said at least two of said jaws each being connected at said a first end to said first shaft has an overall length shorter than an overall length of the at least two other of said jaws such that the said second end of said at least two of said jaws remains unconnected to any other portion of said implant device when configured in said first or second clamping mechanism, wherein said second end of each of said at least two of said jaws each being connected at said first end to said first shaft is configured to remain unconnected to any other portion of said implant device during use; and wherein said shaft has sufficient columnar strength to maintain distraction between the first and second vertebrae via said clamps.
