Abstract

Disclosed is a delivery system for a component, for example, a splitting lead. A splitting lead can have a proximal portion to engage a controller and a distal portion to split apart into sub-portions that travel in multiple directions during implantation into a patient. The delivery system can include a handle and a component advancer to advance and removably engage a portion of the component. The component advancer can be coupled to the handle and advance the component into the patient by applying a force to the portion in response to actuation of the handle by the operator. Also, the delivery system can include an insertion tip with first and second ramps to facilitate advancement of first and second sub-portions into the patient in first and second directions. The leads may have various electrode configurations including, for example, wrapped or embedded electrodes, helical or elliptical coils, thin metallic plates, etc.
