Abstract
A spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume in the spine canal and/or neural foramen. The implant provides a spinal extension stop while allowing freedom of spinal flexion.
Claims32
An implant adapted to be inserted between adjacent first and second spinous processes comprising:
- a first end that defines a first saddle;
- a second end that defines a second saddle;
- a first tether associated with the first saddle;
- a second tether associated with the second saddle;
- the first tether adapted to retain the first spinous process in the first saddle;
- and
- the second tether adapted to retain the second spinous process in the second saddle.
An implant adapted to be inserted between adjacent first and second spinous processes comprising:
- a first end that defines a first saddle;
- a second end that defines a second saddle;
- a first fastener associated with the first saddle, which first fastener is adapted to surround the first spinous process;
- a second fastener associated with the second saddle, which second fastener is adapted to surround the second spinous process;
- the first fastener adapted to retain the first spinous process in the first saddle;
- and
- the second fastener adapted to retain the second spinous process in the second saddle.
An interspinous process implant adapted to be inserted between a first and a second spinous process comprising:
- a first end adapted to engage a first spinous process and a second end adapted to engage a second spinous process;
- and
- at least one fastener secured to an end through a bore, where the fastener surrounds the spinous processes.
An interspinous process implant adapted to be inserted between a first and a second spinous process comprising:
- a body having a first end defining a first saddle, and a second end defining a second saddle, where the first and second saddles are adapted to engage first and second spinous processes;
- and
- at least one fastener secured to an end through a bore, where the fastener surrounds the spinous processes.
An interspinous process implant adapted to be inserted between a first and a second spinous process comprising:
- a body having a first end defining a first saddle, and a second end defining a second saddle, where the first and second saddles are adapted to engage first and second spinous processes;
- a first fastener secured to the first saddle through a first bore and a second bore, where the first fastener surrounds the first spinous process;
- and
- a second fastener secured to the second saddle through a first bore and a second bore, where the second fastener surrounds the second spinous process.
An interspinous process implant having a central body with first and second saddles adapted to receive adjacent spinous processes, the improvement comprising the interspinous process implant having at least one tether secured to at least one saddle in order to retain the interspinous process implant between the interspinous processes.
An interspinous process implant having a central body with first and second saddles adapted to receive adjacent spinous processes, the improvement comprising the interspinous process implant having one tether secured to one saddle and one pin secured to the other saddle in order to retain the interspinous process implant between the interspinous processes.
An interspinous process implant having a central body with first saddle having first and second arms projecting from the first saddle and a second saddle with third and fourth arms projecting from the second saddle, where the first and second saddles are adapted to receive adjacent spinous processes, the improvement comprising the interspinous process implant having a first tether secured to the first and second arms and a second tether secured to the third and fourth arms, where the arms and tethers position the interspinous process implant between the interspinous processes.
