Patent ID: 8287567

Claim:
A device for securing a cranial limb to a cranial top and for simultaneously closing a craniotomy hole, the device comprising: a) a first section made in a single piece comprising: 1) a lower ring comprising a central opening; 2) a cortical riser comprising two struts, each strut comprising a first end and a second end; 3) a handle connected to both first ends of the struts; 4) at least two elastic arms, each elastic arm comprising a first end and a second end; where the first end of each elastic arm is connected to the lower ring and the second end of the elastic arm is connected to the second end of one strut of the two struts of the cortical riser; and 5) a securing ring connected to and surrounding the two struts of the cortical riser at the first end of each strut or between the first end of each strut and the second end of each strut; where the two struts of the cortical riser define a passage, the passage extending between the securing ring and junctions of the second ends of the struts and the second ends of the elastic arms, and extending through the central opening of the lower ring; and b) a second section separate from the first section, where the second section is an upper plate in the general form of an incomplete ring or horseshoe, the upper plate comprising: 1) an internal circumference and an external circumference; 2) a central opening defined by the internal circumference and sized to accept the securing ring of the first section; and 3) a lateral opening extending from the central opening of the upper plate through the external circumference; where the lateral opening is sized to permit passage of both struts of the cortical riser within the lateral opening, thereby allowing the second section to join the first section; and where both the first section and the second section comprise biocompatible elastic material to allow expansion and contraction of the first section and the second section, and to permit detachment of the handle and any portion of the two struts between the securing ring and the handle using a scalpel.
