Patents by Inventor Eric J. Grigsby

Eric J. Grigsby has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220387789
    Abstract: Devices, systems and methods for reducing migration of leads, catheters and similar devices are provided. In particular, devices, systems and methods are provided for creating a slack anchor which assists in maintaining the lead or catheter in a desired position. In some embodiments, the slack anchor is created within the epidural space. When targeting nerve anatomy within the spinal column or in the vicinity of the epidural space, anchoring within the epidural space allows the associated lead or catheter to be anchored as close to the target therapy site as desired or possible. By anchoring close to the target therapy site, the risk of movement or migration is significantly reduced or eliminated.

  • Publication number: 20170312499
    Abstract: Devices, systems and methods are provided for accessing and treating anatomies associated with a variety of conditions while minimizing possible complications and side effects. This is achieved by directly neuromodulating a target anatomy associated with the condition while minimizing or excluding undesired neuromodulation of other anatomies. Typically, this involves stimulating portions of neural tissue of the central nervous system, wherein the central nervous system includes the spinal cord and the pairs of nerves along the spinal cord which are known as spinal nerves. In particular, some embodiments of the present invention are used to selectively stimulate portions of the spinal nerves, particularly one or more dorsal root ganglions (DRGs), to treat chronic pain while causing minimal deleterious side effects such as undesired motor responses.

  • Publication number: 20170239463
    Abstract: Devices, systems and methods are provided for anchoring implantable medical devices to maintain an implanted position. In some embodiments, the medical devices are stimulation leads which are implanted near a portion of the neural anatomy for providing stimulation thereto. To maintain position of the lead, the lead is anchored with the use of a tissue-captured anchor which is attached to the lead at a desired point of anchoring. The anchor maintains position of the lead by resisting movement of the anchor between tissue layers at the point of anchoring.
