Pharmaceutical removal of vascular and/or neuronal extensions form a degenerating disc

ActiveUS20070253930A1Suppression and reduction of sensitivitySuppression and reduction of and activityOrganic active ingredientsPeptide/protein ingredientsMedicineWhole body
The invention provides a method for alleviating discogenic pain by administering a therapeutic agent that disrupts neuronal and / or vascular elements in the disc, which is typically a degenerated disc. Disruption of neuronal elements in the disk includes destroying nerve endings without substantially affecting the central body of the nerve, suppressing activation of the nerve endings, and inhibiting the growth of nerve endings into the disk. Disruption of vascular elements includes causing the vascular extensions to retract from the disk, or suppressing the formation of such extensions. The therapeutic agent may be administered locally via an interbody pump, a bolus or a depot, or may be administered systemically.

Methods for diagnosing and treating pain in the spinal cord

The present invention provides methods, reagents and kits for the diagnosis and treatment of spinal-related pain, e.g., radiculopathic pain, facet pain and discogenic pain. Cytokine biomarkers, e.g., IFNγ can be used to diagnose spine-related injury. It is also a finding of the present invention that spinal-related pain can be alleviated by administering therapeutic agents to the site of diagnostic presence of the cytokine biomarker. This invention further provides methods for extraction of samples from the spine, e.g., disc space samples, epidural samples and facet joint samples.

Probe and device for detecting abnormality of intervertebral disc

The present invention relates to a probe and a device for detecting abnormality of an intervertebral disc. More particularly, the present invention relates to a probe and a device for detecting abnormality of an intervertebral disc that gives vibration stimulation to the inner part of the intervertebral disc and obtains an ultrasonic image in order to sense the abnormality of the intervertebral disc causing discogenic pains and inspects whether the intervertebral disc is abnormal by measuring impedance in the intervertebral disc.The present invention provides a probe for detecting abnormality of an intervertebral disc including: a shaft connector; a vibration generator connected to the shaft connector; and an inspector connected to the vibration generator, wherein the vibration generator vibrates the inspector by using a piezoelectric element and a device for detecting abnormality of an intervertebral disc.

System and method for electrical modulation of the posterior longitudinal ligament

A method for treating a patient having discogenic pain includes implanting a neurostimulation lead within an anterior portion of the epidural space adjacent to the posterior longitudinal ligament. A plurality of electrodes is attached to the lead and the lead is implanted with at least a portion of the electrodes facing the posterior longitudinal ligament. The lead may be implanted in the lumbar region of the patient's spine, posterior and parallel to the posterior longitudinal ligament. Electrical stimulation energy applied to the patient through the electrode lead implanted in this manner inhibits the pain signals traveling within the posterior longitudinal ligament. Thus, the applied electrical stimulation energy has an anesthetic effect on the pain fibers adjacent to the posterior longitudinal ligament.

Method for relieving pain and regenerating intervertebral disc

Disc degeneration and chronic back pain are caused by a transport hindrance of oxygen, nutrients and pH buffer from capillaries in endplates into mid-layer of the intervertebral disc. A fluid absorbing conduit is inserted into the intervertebral disc, drawing and delivering the oxygen, nutrients and pH buffer in fluid of body circulation from capillaries at endplates into the mid-layer of the disc. The disc undergoes thousands of relaxation and compression cycles each day from daily activity of the patient. During relaxation phase, the fluid of body circulation containing oxygen, nutrients, and pH buffer is infused into the fluid absorbing conduit. During compression phase, the oxygen, nutrients, and pH buffer in the fluid absorbing conduit is dispersed into the mid-layer of the disc. The pH buffer, bicarbonate, neutralizes the lactic acid to relieve the discogenic pain. Oxygen inhibits hypoxic inflammation and production of lactic acid to further reduce the discogenic pain. Nutrients nourish the disc cells to rebuild or regenerate the disc matrix.Therapeutic agents can be added into the fluid absorbing conduit or injected into the disc implanted with the fluid absorbing conduit to expedite pain relief and disc regeneration. The therapeutic agents can be pH buffering agent, antibiotic, anti-inflammatory drug, anesthetic, antacid, nutrient, sulfate, anti-depressant, calcium channel blocker, growth factor, cells or other.
