Publication number: 20140276591Abstract: A regeneration device and method for sealing annular tears between the nucleus pulposus and the annulus fibrosus of an intervertebral disc. The regeneration device includes a trocar having a sharp tip at a distal end, an inner cavity, and a handle portion attached to a proximal end of the trocar. The device further includes a plunger coupled to a catheter that extends through the inner cavity. The regeneration method includes inserting the trocar into an intervertebral disc via Kambin's triangle, and once the trocar reaches the nucleus pulposus, the catheter is extended alongside the annulus fibrosus wall to surround the nucleus pulposus. A syringe is mounted to the plunger and injects a biochemical, biological and/or synthetic material through multiple ports in the catheter to form a collagen barrier that prevents the nucleus pulposus from protruding through the annulus fibrosus.Type: ApplicationFiled: March 14, 2014Publication date: September 18, 2014Applicant: MI4SPINE, LLCInventors: Miguelangelo J.

Patent number: 8690920Abstract: An interspinous process spacer insertion device that positions an interspinous process spacer between the spinous process of adjacent vertebrae in a minimally invasive percutaneous surgical procedure. The device includes a trocar rod that extends through a cannulated sleeve. The spacer is attached to the end of the cannulated sleeve, where a trocar tip of the trocar rod extends through the spacer. The trocar rod is moved through the cannulated sleeve and an incision in the patient, and is positioned between the spinous process of the vertebra to align the device. The cannulated sleeve is then moved down the trocar rod so that the spacer slides between the spinous process, and the trocar rod is then withdrawn from the patient. The spacer is then rotated so that it locks behind the spinous process, and the cannulated sleeve is detached from the spacer and removed from the patient.Type: GrantFiled: December 22, 2010Date of Patent: April 8, 2014Assignee: Mi4Spine, LLCInventors: Miquelangelo J.
