Abstract: Devices, systems and methods for minimally open orthopedic spine surgery are disclosed. A first flexible screw-based retractor is designed to be coupled to each pedicle screw inserted into adjacent vertebral bodies. A retractor system is provided in which a first retractor blade is mounted to one of the screws and a second movable retractor blade is moved away from the first blade, in a medial direction, to create a working channel through which the disc space may be accessed for passing instruments and implants. Light may be incorporated into the device to illuminate the surgical field. One or all of the retractor blades may be made of a sterilizable plastic or metal and be disposable or reusable.

Abstract: The present invention relates to a system and methods generally aimed at surgery. More particularly, the present invention is directed at a system and related methods for performing surgical procedures and assessments involving the use of neurophysiology.

Abstract: The present invention relates to a system and methods generally aimed at monitoring the angular orientation between two locations within a fluoroscopic image and especially for monitoring the angular orientation between two locations within a fluoroscopic image and a predetermined target angle.

Abstract: A multi-layer pre-drape apparatus is applied to a patient before the patient is moved into the operating room. The multi-layer pre-drape apparatus includes a lower layer with a center aperture and an upper layer that covers the aperture. The multi-layer pre-drape apparatus can be placed on a sterilized area of the patient to maintain the cleanliness of the incision area. Alternatively, the multi-layer pre-drape apparatus can be placed on the patient and sterilization fluid can be applied to the skin of the patient through the aperture. The patient can then be moved into the operating room and the upper layer of the multi-layer pre-drape can be removed to expose the sterilized area of the patient in the aperture. Additional drapes can be added to the pre-drape apparatus.

Abstract: A retractor having a pair of blades is disclosed. A ring having an opening is attached to one end of the blades. The blades define a channel therebetween. The blades may be pivotally coupled to the ring. The retractor may have at least two conditions. In a first condition, the retractor is insertable through an incision in a patient's skin to an operative site. In a second condition, the retractor may be manipulated for retracting tissue surrounding the operative site. Instruments, prostheses, or tissue may be inserted or removed through the channel of the retractor.

Abstract: A device, system and method for orthopedic spine surgery using a novel screw-based retractor, disclosed herein, that allows for access to the spine through a minimally or less invasive approach. The retractor device is designed to be coupled to a pedicle screw and then to have opposed arms of the retractor spread apart to open the wound proximally. The retractor is removed by pulling it out of the wound whereby the retractor is deformed to pass over the pedicle screw head. The retractor is intended to be made of a stiff plastic material, sterile packaged and disposable after one use. A system and method for using the retractor and performing a minimally invasive spine surgical procedure are also disclosed.
