Abstract: Spinal implants include an elongated body portion dimensioned and configured for percutaneous introduction into a target interspinous process space, at which interspinous distraction and/or spinal fusion are desired. The body portion can include a threaded outer surface, or alternatively a smooth surface. The body portion can include one or more interior cavities, and can include deployable engagement members adapted and configured to move in tandem between a stowed position retracted within the interior cavity of the body portion and a deployed position extended from the interior cavity of the body for engaging adjacent spinous processes. An internal drive assembly for selectively moving the engagement members from the stowed position to the deployed position can be provided, as can a elements for locking the engagement members in a deployed position.

Abstract: A spinal implant for treating lumbar spinal stenosis or as an adjunct to spinal fusion. The implant includes a body portion having an interior cavity. A plurality of locking wings are adapted and configured to move between a stowed position retracted within the interior cavity of the body portion and a deployed position extended from the interior cavity of the body portion. In the deployed position, the wings fix the implant in a selected interspinous space. A cable and wheel arrangement moves the plurality of locking wings from the stowed position to the deployed position and a ratchet/pawl assembly prevents backward movement of the wings.

Abstract: An adjustable concrete form comprises at least one tube and an adjustable stake having a post and a tube cradle. A bracket is removably connected to the tube for supporting rebar in spaced-apart relation to the excavation bottom. The bracket includes a tube engaging portion and a rebar supporting portion. The tube engaging portion is configured for connecting the bracket to the tube. The rebar supporting portion extends laterally from a proximal end connected to the tube engaging portion to a distal end spaced from the tube engaging portion.

Abstract: An adjustable concrete form comprises at least one tube and an adjustable stake having a post and a tube cradle. The tube has at least one drainage aperture providing the form with drainage. The adjustable stake is configured for adjustably supporting the tube in spaced-apart relation to an excavation bottom. The post has at least one slender end to facilitate driving the post partially into the excavation bottom. The tube cradle is configured for releasable engagement with the tube to thereby secure the tube relative to the post and to support the tube in spaced-apart relation to the excavation bottom. The tube cradle is adjustably connected to the post so that adjustment of the post relative to the cradle effectuates adjustment of the tube relative to the excavation bottom.

Abstract: A footing/foundation form with an integral drain having two substantially parallel spaced apart, serpentuitous walls. Each wall includes a plurality of hollow tubes elevated "to grade" above an excavation bottom by a stake and clip mechanism with gravel filled between the elevated tubes and the excavation bottom such that the elevated tube and gravel both engage concrete poured between the walls. The tubes are common 10-foot PVC tubes with a plurality of holes positioned away from the footing/foundation thereby providing the form with an integral drain. The stakes are preferably pieces of reinforcing bar and the clips, while quite effective, are also inexpensively manufactured.
