Percutaneous tools for minimally invasive access to the carotid sheath for vagus nerve stimulation

Various aspects describe a lead delivery system for percutaneous introduction of a lead to a stimulation site near a neural target, such as the vagus nerve for nerve stimulation. The lead delivery system may include a needle assembly having a needle adapted to cut through tissue and provide initial access into the carotid sheath. The needle may be retracted into the lead delivery system to prevent cutting structures in the carotid sheath. The lead delivery system may also include a dilator assembly having one or more dilators to dilate a path to the stimulation site. The lead delivery system may further comprise a dilator assembly including a retractable needle adapted to cut through tissue. One or more locating elements, alternatively or in addition to one or more imaging elements, may be used on individual components of the lead delivery system for enhanced trackability and locatability within the body.

Systems And Methods For Off-Axis Treatment Of A Vertebral Body

Systems and methods for augmenting a vertebral body. An introducer device includes a shaft having a flexible distal portion with a pre-set curve in an unconstrained state. An input provided to an actuator to tension a pulling element to move the pre-set curve to a constrained state in which the distal portion and a flexible sheath conforming to the shaft at least partially straighten. The introducer device is removable from the sheath remaining offset from a longitudinal axis. A spacer hub facilitates proximal movement of the sheath relative to an access cannula expose a balloon through a syringe-style input. A hub of the access cannula may be adjustable to selectively adjust an interference surface relative to a datum. At least two radiopaque markers may be disposed on the sheath with relative positions between the markers viewable on lateral and A-P radiography to determine the location and/or curvature of the sheath.
