An interbody fusion device having an accordion-like structure, wherein the device in inserted into the disc space in its collapsed configuration and then expanded into its expanded configuration by compressing the accordion-like portion of the device. In some embodiments, a pre-formed tube with an accordion-like structure over a portion of its length is inserted in a relaxed (collapsed) configuration, giving the tube a minimum possible diameter. This tube has a cable running through it that is fixed to a distal end portion of the tube and extends past the proximal end portion of the tube to the outside of the patient. Once the tube is positioned on the rim of the endplate, the proximal end of the cable is pulled, thereby tensioning the cable and causing the accordion portion of the tube to become shorter in length but larger in diameter.

Bellows-like expandable interbody fusion cage

This invention includes surgical retractors that comprise an expandable frame that includes at least two base components, a connector, and at least two retractor blades attached to the expandable frame. Also included are surgical retractors that comprise a housing component that includes a cylindrical portion and a contiguous blade portion, assemblies comprising a surgical retractor assembled to at least one obtruator, illuminated surgical cannulas, and methods of using the same during a surgical procedure.

Surgical retractor systems and illuminated cannulae

A blade extending tower is provided for setting blade depth on retractors having telescoping or extending blades. The blade extending tower features a base, a column extending from the base, and mating features on the column configured to engage the blades of a retractor to extend the blades to a desired blade depth. Blade depth of the retractor is set buy sliding the retractor onto the blade extending tower such that the mating features of the blade extending tower engage the blades or the retractor, stopping the blades progression while the rest of the retractor continues along the length of the column. Thus the blades of the retractor are extended from the retractor to a depth determined by the configuration of the blade extending tower.

Retractor blade extender tower

The present invention provides a non-rigid retractor for providing access to a surgical site, such as a patient's spine, during a surgical process. When used in spinal surgery, the non-rigid retractor allows a surgeon to operate on one or more spinal levels. The non-rigid retractor includes at least one flexible strap anchored at a first end to the spine or other internal body part at the surgical site. The body of the at least one flexible strap extends from a skin incision and is anchored at a second location external to the body to retract skin and muscle from the surgical site, allowing adequate visualization of the surgical site and providing access for implants and surgical instruments to pass through the retractor and into the surgical site.

Surgical methods and surgical kits

A surgical access device includes a proximal frame of fixed construction and a plurality of tissue engaging blades connected to the frame. The plurality of tissue engaging blades may include a first blade that is rotatable, independent of other blades, about an axis that is oriented approximately parallel to a plane defined by the proximal frame.

Surgical access devices and methods of minimally invasive surgery

A surgical retractor includes a plurality of blade assemblies interconnected by a plurality of racks. One or more of the blade assemblies is movable along a rack to selectively expand the retractor. At least one of the blade assemblies includes a blade that is rotatably connected to the blade assembly and that is rotatable independent of other blades of the retractor.

Surgical retractors and methods of minimally invasive surgery

A surgical retractor for use with a spinal stabilization system including a plurality of bone anchors and a plurality of anchor extensions. The surgical retractor includes a frame positionable between a first anchor extension connected to a first bone anchor implanted in a first vertebra and a second anchor extension connected to a second bone anchor implanted in a second vertebra and a first retractor blade connectable to the frame for retracting tissue between the first anchor extension and the second anchor extension.
