Abstract: The present invention provides devices, systems and methods for anchoring medical devices to hard tissues, such as bones or bony structures, particularly vertebrae. By anchoring these medical devices directly to the surrounding hard tissue, the devices are anchored closer to the source of treatment. This provides additional stability and reduces migration of the device at the treatment site. Also, by attaching to hard tissue rather than soft tissue, a stronger attachment is often able to be made.

Abstract: Devices, systems and methods for treating pain or other conditions while minimizing possible complications and side effects. Treatment typically includes electrical stimulation and/or delivery of pharmacological or other agents with the use of a lead or catheter. The devices, systems and methods provide improved anchoring which reduces migration of the lead yet allows for easy repositioning or removal of the lead if desired. The devices, systems and methods also provide for simultaneous treatment of multiple targeted anatomies. This shortens procedure time and allows for less access points, such as needle sticks to the epidural space, which in turn reduces complications, such as cerebral spinal fluid leaks, patient soreness and recovery time. Other possible complications related to the placement of multiple devices are also reduced.

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.

Abstract: 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. A system includes a lead having a lead body and at least one electrode; and 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 when the lead is positioned in a body. 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.

Abstract: Devices, systems and methods are provided for stimulation of tissues and structures within a body of a patient. In particular, implantable leads are provided which are comprised of a flexible circuit. Typically, the flexible circuit includes an array of conductors bonded to a thin dielectric film. Example dielectric films include polyimide, polyvinylidene fluoride (PVDF) or other biocompatible materials to name a few. Such leads are particularly suitable for stimulation of the spinal anatomy, more particularly suitable for stimulation of specific nerve anatomies, such as the dorsal root (optionally including the dorsal root ganglion).

Abstract: Devices, systems and methods are provided for stimulating a target tissue, particularly a dorsal root ganglion. The devices and systems have one or more electrodes, wherein the electrodes are positionable in disperse locations within the specific target area. In some embodiments, the position of at least some of the electrodes is adjustable and optionally independently positionable. Some or all of the electrodes may be used to stimulate the desired tissue, such as to stimulate a specific portion of the target area. Or, the one or more electrodes that fall near the target tissue may be used to stimulate the tissue while the other electrodes are not used. When stimulating the dorsal root ganglion, sensory pain signals are blocked providing relief to the patient.

Abstract: A suturing device suitable for anastomosis procedures. The suturing device includes a suture guid and a needle holder.

Abstract: A method and apparatus for performing an upper tibia osteotomy comprising cutting a wedge from the bone using a first guide assembly to cut a first slot partially through a bone and a second guide assembly to cut a second intersecting slot to define a wedge shaped bone segment. An external compressor device draws the osteotomy closed by plastic deformation of the unsevered portion of the bone. The bone is secured by a plate and screws.
