Publication number: 20100063510Abstract: A method and device for the insertion of a vertebral cage that may be done through a posterior approach that is minimally traumatic and does not require retraction of the spinal cord, dural sac or spinal nerves. The insertion of the cage may therefore be parallel to the spinal cord and the cage will be rotated ninety degrees (or as desired or required) in the vertebral body defect or as applicable to achieve its proper positioning before expansion.Type: ApplicationFiled: January 7, 2008Publication date: March 11, 2010Applicants: UNIVERSITY OF VIRGINIA PATENT FOUNDATION, KYPHON, INC.Inventors: Vincent Arlet, Christopher U.

Publication number: 20080312546Abstract: A catheter with a balloon anchor may be sized to fit through an inner needle and introduced into the patient through the needle. The inner needle may comprise an atraumatic needle with a side port and/or a blunt tip. The catheter may include a radiopaque coil disposed over the distal portion of the catheter body to assist with catheter placement when viewed with fluoroscopy and/or x-ray. The distal portion of the catheter can be very flexible. A balloon inflation tube may terminate proximal to a proximal end of the expandable balloon anchor such that the distal portion of catheter can be flexible. This termination of the inflation tube may also position the inflation tube away from the annulus and nerve roots, so as to avoid irritation of the annulus and rubbing of the nerve roots that may potentially obscure FAD test results.Type: ApplicationFiled: June 15, 2007Publication date: December 18, 2008Applicant: Kyphon Inc.Inventors: David Miller, Michael Smith, Steve Mouw, Erika Palmer

Publication number: 20080312637Abstract: A system includes components that allow the user to select how to perform disc diagnosis with the components of the system. The system components include a FAD catheter, a guidewire and stylet, in which both the guidewire and stylet are compatible with the catheter. The user may select to insert the catheter into the disc with a stylet included in the system. The user may also select to insert the catheter into the disc with the guidewire included in the system, for example after the guidewire has been placed with a rigid needle.Type: ApplicationFiled: June 15, 2007Publication date: December 18, 2008Applicant: Kyphon Inc.Inventors: David Miller, Michael Smith

Publication number: 20080215033Abstract: Methods, devices and systems facilitate diagnosis, and in some cases treatment, of back pain originating in intervertebral discs. Methods generally involve introducing one or more substances into one or more discs using a catheter device. In one embodiment, a patient assumes a position that causes back pain, and a substance such as an anesthetic or analgesic is introduced into the disc to determine whether the substance relieves the pain. Injections into multiple discs may optionally be performed, to help pinpoint a disc as a source of the patient's pain. In some embodiments, the catheter device is left in place, and possibly coupled with another implantable device, to provide treatment of one or more discs. A catheter device includes at least one anchoring member for maintaining a distal portion of the catheter within a disc.Type: ApplicationFiled: December 26, 2006Publication date: September 4, 2008Applicant: Kyphon, Inc.Inventors: David R.

Patent number: 7335203Abstract: A system and method for immobilizing adjacent spinous processes in accordance with the present invention can supplement primary fusion devices and methods by immobilizing spinous processes while bone from adjacent vertebral bodies grows together. The system requires less extensive surgical procedures than other common supplemental devices, and preferably does not require bone or ligament removal. One such system comprises three spacers positioned between spinous processes and adjustably connected with a plate positioned on either side of the spinous processes. Each plate includes grips, with each grip positioned adjacent to the spinous process, forming a clamp with a grip connected with the opposing plate.Type: GrantFiled: February 9, 2004Date of Patent: February 26, 2008Assignee: Kyphon Inc.Inventors: Charles J.
