Minimal Invasive Spine Surgery (MISS) as a surgical approach is increasingly utilized because of the advantages it offers over conventional spine surgery. The smaller incision results in decreased tissue damage, less blood loss, decreased hospital stay & faster postoperative recovery. The drawbacks of MISS are the long learning curve of working through a smaller incision, longer length of surgery, & potential higher complication rate due to compromised visual field. These limitations can be overcome by more effectively using imaging and navigational devices. The pedicle device simplifies the hardest part of MISS instrumented fusion of conventional pedicle screw insertion by introducing a percutaneous temporary device to locate and create the channel for later conventional pedicle screw implantation using available imaging techniques. This results in faster conventional pedicle screw insertion with precision, thereby decreasing implantation error and minimizing soft tissue injury and blood loss, as well as neurological, vascular, and dural injuries and complications.

Lead Tracking of Implantable Cardioverter-Defibrillator and Cardiac Resynchronization Therapy Devices improve upon the process of implantation of ICD-CRT devices, placing their leads, and improving the information fed back to the device and/or clinician. Tracking of the placement of the leads during implantation is accomplished along with monitoring the leads once implanted. Benefits include reducing the risk and complication rate, simplifying implantation procedure, and enabling the extraction of vital data not previously available. Leads are tracked to at least minimize the need to use fluoroscopy. Three dimensional tracking (10) is employed to facilitate obtaining of data that allows the surgeon to better visualize lead insertion and placement. Placement of the leads during a procedure requires use of an external tracking component along with means and method for tracking the implantable leads. Transmitting antennas (10, 110) are provided, equal in number to the number of degrees of freedom of tracking required. A link (50) between the sensor (70) and the computation unit (40) can be wired or wireless. Once leads are implanted, heart wall motion must be monitored via the tracking of the leads within a clinical or home environment. Such tracking of the leads may be accomplished in real time.

Wound closure apparatus is provided including a body having an elongated, lowermost force-transmitting surface operable to be placed in a proximal, external, wound-closing position on a patient, together with a force-exerting assembly coupled with the body and operable to exert a downwardly directed force serving to generate wound-closing pressure against the patient's tissue.
