20090105621 | Protective and Cosmetic Covering for External Fixators - A removable protective covering is provided that can be secured about an external fixation device on the upper or lower extremity of a patient. The covering includes a fabric form that is sized and configured to accommodate varying sizes of external fixation devices and uses readily engageable/releasable closure elements or fasteners to securely engage the covering about the fixator and the extremity. A drawstring closure may be provided at the open ends of the covering to tighten the end about the patient's limb. Ventilation features may be provided including vents with and without additional devices to generate air flow through the covering. The covering for a lower extremity fixation device may be configured for removably attachment to a foot plate and the foot plate itself may be configured to support or attach to the fixation device. | 04-23-2009 |
20090105836 | Devices and techniques for a posterior lateral disc space approach - This invention relates to devices and instruments for implant insertion through a posterior lateral opening to the disc space. The instruments include an implant inserter, and the devices include a spinal fusion implant engageable by the implant inserter. The implant provides bilateral support of the adjacent vertebrae when inserted into the disc space from a postero-lateral approach. | 04-23-2009 |
20090131946 | Devices and Methods for the Restoration of a Spinal Disc - A system and method is provided for maintaining a proper intervertebral disc height during the replacement or augmentation of the spinal disc. In one embodiment, a cannulated distractor is used to distract the adjacent vertebrae and maintain a proper disc space height. The cannulated distractor is fluidly connected to a source of fluent material for injection into the disc space. The distraction includes a distraction tip resident within the disc space that includes a central lumen and a number of openings communicating with the lumen to dispense the fluent material within the disc space. | 05-21-2009 |
20090254123 | Dynamic Spinal Stabilization System - A dynamic stabilization system includes a stabilization element, such as a spinal rod, a plurality of bone anchors, such as bone bolts, and a like plurality of connectors for connecting the bolts to the spinal rod. At least some of the connectors include a flexible element between the bone anchor and the rod and an adjustment element for adjusting the flexibility of the flexible element, to thereby adjust the dynamic flexibility between the rod and the bone anchor. In one embodiment, the flexible element is a flexible bearing element of a rod end bearing. | 10-08-2009 |
20090254181 | Intervertebral spacers with side wall accessible interior cavity - Intervertebral spacers and methods of promoting fusion bone growth in the space between adjacent vertebrae are provided. The spacers include an elongated body having a first end, a second end and an outer surface. Side walls connect the first and second ends. The elongated body also defines an interior cavity. The side wall defines an opening to the interior cavity in a side of the elongated body. At least one of the first and second ends has a discontinuity, such as a concave surface, for nesting with an adjacent spacer. The methods of promoting fusion bone growth include utilizing the inventive spacers described herein. | 10-08-2009 |
20100130959 | DEVICE AND METHOD FOR DELIVERY OF THERAPEUTIC AGENTS VIA ARTIFICIAL INTERNAL IMPLANTS - A device is provided for use with a medical implant for delivering an agent to a designated site of action in a body of a patient. The agent-delivery device comprises a body member adapted to be secured to the medical implant and an agent-delivery component associated with the body member. The agent-delivery component includes a therapeutic agent for treating the body of the patient. The agent-delivery component is configured to release the therapeutic agent after implantation in the body of the patient. | 05-27-2010 |
20110178465 | DEVICE AND METHOD FOR DELIVERY OF THERAPEUTIC AGENTS VIA INTERNAL IMPLANTS - A device is provided for use with a medical implant for delivering an agent to a designated site of action in a body of a patient. The agent-delivery device comprises a body member having an inner surface and a projection on the inner surface of the body member. An agent-delivery medium is associated with the body member. The agent-delivery medium includes a therapeutic agent for treating the body of the patient. The body member is adapted to be secured to the medical implant such that the projection operatively engages the medical implant for spacing the inner surface of the body member from the implant, and the agent-delivery medium is configured to release the therapeutic agent after implantation in the body of the patient. In alternative embodiments, the agent-delivery device comprises a first body member having an inner surface and a second body member having an inner surface. When connected, the inner surfaces of the first body member and the second body member define a cavity adapted to receive the medical implant. The body member may also define an opening therethrough, the opening configured to receive an anchor member for fixing the body member in a body of a patient. | 07-21-2011 |
20110288587 | ANTERIOR LUMBAR PLATE AND METHOD - A plate of biocompatible material is provided having curvature in two planes such that it conforms to the curvature of the L5 vertebral body and to the patient's lordotic curve. Holes are provided receiving screws for anchorage in the vertebral body and sacrum. A flange or foot portion on the plate provides a wider base end area for support in the L5-S1 interspace. The foot portion is also arranged for appropriate entry angle of screws into the sacrum such as to improve anchorage in the sacrum. Anti-backout and low profile features are incorporated. The anterior lumbar plate is situated to maintain the anterior interbody bone graft in compression by resisting tensile forces during extension. | 11-24-2011 |
