摘要:
An apparatus for monitoring the characteristics of tissue adjacent a surgical site and communicating that information to a health care provider includes a retractor, a sensor, and a processing system. The sensor is disposed on the retractor and is configured to measure a parameter indicative of at least one characteristic of the tissue adjacent the first or the second blade. The processing system is in communication with the sensor and configured and arranged to receive information from the sensor indicative of the measured parameter. It includes a threshold stored therein indicative of excessive trauma to the tissue and it is configured in a manner such that it compares the received information to the stored threshold and communicates information to the health care provider regarding the comparison.

Medical devices for the treatment of spinal conditions are described herein. Such a medical device may include a pair of plates with spikes adapted to be embedded in a superior spinous process and an adjacent inferior spinous process. The device may also allow relative motion between adjacent spinous processes.

Various embodiments of a vertebral tension band assembly and associated connection structure are provided. The tension band assemblies may be attached to vertebral bodies to, for example, connect one vertebrae to another, retain the band in approximately a preferred position by application of tension to the band during insertion and/or limit, impede, inhibit, reduce or interfere with the separation from one vertebra to another and may further block, impede, interfere with, inhibit, reduce or present an obstacle to dislodgement of a spinal implant from between the vertebrae to which it is attached. Flexible band portions of the assemblies may be treated and/or configured to promote bony integration between the band and the associated vertebrae, limit tissue adhesion to the band, and/or to elute a therapeutic substance from the installed band to the surgical site.
摘要:
Embodiments of the invention include instruments, implants, and methods for surgically treating facet joints of vertebrae. An instrument may be advanced into one or more facet joints to one or both separate vertebrae and remove tissue from one or more articular processes. A stop on the instrument may be used to terminate advancement of the instrument by contacting a vertebra, and one or more implants may be placed into one or more facet joints.

摘要:
A spinal implant including an interbody device and an anchor device. The interbody device is sized and shaped to be positioned within an intervertebral disc space between adjacent upper and lower vertebrae. The anchor device is at least partially formed of a resorbable material and is coupled to the interbody device and anchored to the upper and lower vertebrae. The anchor device is configured to temporarily secure the interbody device to the upper and lower vertebrae for a period of time sufficient to facilitate bone growth onto and/or through the interbody device and is thereafter resorbed into the body.

摘要:
In one form, a method for stabilization of a facet joint of the spinal column includes forming a cavity between adjacent bones defining the facet joint and positioning an implant in the cavity between the adjacent bones. In one aspect of this form, the method also includes positioning a bone anchor across the facet joint and engaging the bone anchor with each of the adjacent bones to force the bones toward one another and clamp the implant therebetween. In a further aspect of this form, the implant is a cancellous bone dowel and becomes fractured into a plurality of fragments upon being clamped between the adjacent bones and/or otherwise interacting with the bone anchor. In another form, systems and devices for performing percutaneous facet joint stabilization and/or fusion are provided. However, different forms and applications are also envisioned.
摘要:
A diagnostic system is provided that occupies a small area, provides sensing and transmitting of various diagnostic indicia, and with the aid of a healthcare professional, diagnoses and responds to such measurements. In the context of the spine, the diagnostic system comprises a spinal implant situated between two adjacent vertebrae, an antenna for sending and/or receiving signals to and/or from a remote location, a sensor for measuring at least one diagnostic condition, an activating element that has the ability to affect the at least one diagnostic condition, a power source to provide power to the diagnostic system, and a network that electrically connects the antenna, sensor, activating element and battery source.
