Abstract: A device which illuminates internal tissue and organs of a patient is described. The illumination member includes an array of light-emitting diodes (“LEDs”). The arrangement of the array depends on the configuration of the device and the procedure for which the device is being used. In all cases, the illumination member is used to illuminate relevant organs or structures in the body in order to increase visibility during surgical procedures. The LED array reduces the potential for inadvertent injury to internal structures for procedures located throughout the body. These procedures include those involving the reproductive organs of males and females, gastric and bariatrics, and other structures in the abdomen.

The syringe may be designed to incorporate surgical navigation and laparoscopic systems.

Abstract: An implant for interbody fusion of vertebrae comprising a unibody cage structure having an enveloping cage volume and a minimized material volume. The cage structure comprises a first and a second generally planar ring member, each ring member formed from an opposing pair of lengthwise joists and an opposing pair of cross joists, the joists together forming a large opening through the ring member. The ring members are fixedly sandwiched on a plurality of support members, the support members holding the ring members in a spaced apart relationship to thereby provide a large void volume relative to the enveloping cage volume, to thereby allow for receipt of a large volume of bone graft within the cage structure.

Abstract: A unitary adhesive retractor is provided for supporting a patient's excess/redundant tissue to maintain the excess/redundant tissue away from an incision or other existing wound. The retractor defines a top-to-bottom length and a side-to-side width greater than one-half the top-to-bottom length, and comprises a stretchable, air-permeable fabric layer adherable directly to the excess/redundant tissue by means of a silicone gel adhesive which coats at least a substantial portion of a bottom surface of the fabric layer. When the retractor is placed in tension upon application of the retractor to a patient, due to the weight of the excess/redundant tissue, forces generated by the weight of the excess/redundant tissue are transferred through the gel adhesive to the fabric layer, such that the gel substantially protects the dermis of the patient from sheer forces generated by the weight of the excess/redundant tissue being evenly distributed to the dermis of the patient.

Abstract: A multi-portal method for treating a subject's spine includes distracting adjacent vertebrae using a distraction instrument positioned at a first entrance along the subject to enlarge an intervertebral space between the adjacent vertebrae. An interbody fusion implant can be delivered into the enlarged intervertebral space. The interbody fusion implant can be positioned directly between vertebral bodies of the adjacent vertebrae while endoscopically viewing the interbody fusion implant using an endoscopic instrument. The patient's spine can be visualized using endoscopic techniques to view, for example, the spine, tissue, instruments and implants before, during, and after implantation, or the like. The visualization can help a physician throughout the surgical procedure to improve patient outcome.
