Patent number: 9017389Abstract: A method of treating a facet joint of a patient. The facet joint includes a superior facet having superior articular face and an inferior facet having an inferior articular face. A distal end of an implant delivery cannula is extended between the superior and inferior articular faces. The implant delivery cannula has a channel extending therethrough. An implant is moved through the channel until the implant is between the superior and inferior articular faces while at least a portion of the implant is within the channel. The implant includes a first surface and a second surface.

Patent number: 8394125Abstract: A system for treating a facet joint of a patient including superior and inferior resurfacing devices. The superior device includes a resurfacing body configured to conform to a shape of a superior facet articular face, and the inferior device includes a resurfacing body configured to conform to a shape of an inferior facet articular face. Each resurfacing body exhibits sufficient flexibility to transition from a relatively flat state to an inserted state in which the resurfacing body substantially matches any multi-planar concavities of the corresponding facet articular face in the presence of compressive forces. With this construction, the system is capable of establishing a new sliding interface within the facet joint, and can be inserted on a minimally-invasive basis. The resurfacing bodies can be formed of PEEK, and can include teeth that engage the corresponding facet articular face.Type: GrantFiled: July 24, 2009Date of Patent: March 12, 2013Assignee: Zyga Technology, Inc.Inventors: Robert Assell, Brian P.
