Abstract
A device for attachment to a spinal implant construct is disclosed. The device generally includes at least one pedicle screw with a housing adapted for subcutaneous implantation. The housing comprises an electrical battery and an electrically conductive attachment to conduct electrical current from the battery to the screw. Once the screw is inserted into the patient's pedicle, the housing and attachment are inserted in the patient either by minimally invasive tubing or through a minimally invasive incision. The attachment may be attached to the implant construct after the pedicle screw has been inserted into the patient's pedicle.
Claims21
A device for attachment to a spinal implant system including at least a first pedicle screw, the device comprising:
- a housing adapted for subcutaneous implantation;
- an electrical battery within said housing;
- an electrically conductive attachment for conducting electrical current from said battery to the pedicle screw;
- wherein, after insertion of the pedicle screw into a patient's pedicle, said housing and said attachment collectively are sized and adapted to be minimally invasively inserted in a patient via:
- minimally invasive tubing, minimally invasive incision through soft tissue, or both;
- wherein said attachment is attachable to the implant system after the pedicle screw is implanted in a patient's pedicle to provide said electrical current to the pedicle screw.
A device for attachment to an implant system including at least a first screw, the device comprising:
- a housing adapted for subcutaneous implantation;
- an electrical battery within said housing;
- an electrically conductive attachment for conducting electrical current from said battery to the screw;
- wherein said housing includes a threaded member which upon rotation axially advances and cams at least one finger of said attachment to close around the implant system.
A surgical method, comprising the acts of:
- (a) Surgically:
- Threading a first pedicle screw through a first pedicle and into a vertebral body;
- Threading a second pedicle screw through a second pedicle and into a vertebral body;
- Connecting a rod to said first pedicle screw and said second pedicle screw to form a spinal construct;
- and,
- (b) Thereafter, surgically:
- Attaching a device posteriorily to said spinal implant construct, the device comprising:
- a housing adapted for subcutaneous implantation;
- an electrical battery within said housing;
- an electrically conductive attachment for conducting electrical power from said battery to the spinal implant construct.
