Publication number: 20220387789Abstract: 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.Type: ApplicationFiled: August 15, 2022Publication date: December 8, 2022Inventors: Eric J. Grigsby, Daniel M. Brounstein, Fred I. Linker

Publication number: 20170312499Abstract: 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.Type: ApplicationFiled: November 16, 2015Publication date: November 2, 2017Inventors: Fred I. Linker, Daniel M. Brounstein, Albert G. Burdulis, Eric T. Johnson, Phillip C. Burke, Evan S. VandenBrink, Eric J. Grigsby, Henry L.S. Tan

Publication number: 20170239463Abstract: 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.Type: ApplicationFiled: October 13, 2015Publication date: August 24, 2017Inventors: Eric J. Grigsby, Albert G. Burdulis, Fred I. Linker, Evan S. Vandenbrink, Jeffrey J. Lee

Publication number: 20150251004Abstract: A system includes a lead having a lead body and at least one electrode; and a retention feature disposed along the lead body proximal to the at least one electrode and configured to assist in atraumatically anchoring the lead to nearby tissue when the lead is positioned in the body. Alternatively, a system includes a lead, a lead body, at least one electrode; with a coiled retention feature disposed along the lead body proximal to the at least one electrode and configured to assist in anchoring the lead to nearby tissue. A lead for stimulating a target neural tissue includes an elongate body; at least one electrode disposed along the elongate body; and a passive retention feature disposed along the lead body proximal to the at least one electrode and configured to assist in anchoring the elongate body to tissue near the target neural tissue.Type: ApplicationFiled: May 21, 2015Publication date: September 10, 2015Inventors: Mir A.

Publication number: 20150099936Abstract: Devices, systems and methods are provided for accessing a target location in the body of a patient, particularly within the epidural space. A system includes a sheath and a sheath support supporting the sheath to reduce or avoid kinking. The sheath support closely fits within the sheath while maintaining free sliding therein. The sheath support has a non-compliant outer diameter maintaining the inner diameter of the sheath and preventing the sheath walls from collapsing into a kink, particularly during low radius bends that may occur during delivery. The sheath support may include a distal tip configured to resist retraction into the sheath until a threshold force is reached which causes the distal tip to at least partially retract into the lumen of the sheath. Likewise, the distal tip may be fully retractable through the sheath so that the sheath support is removable from the proximal end of the sheath.Type: ApplicationFiled: October 9, 2014Publication date: April 9, 2015Inventors: Albert G.
