LEAD INTRODUCER FOR AN IMPLANTABLE ELECTRICAL STIMULATION SYSTEM

摘要

A lead introducer includes an outer needle with an outer-needle body. T he outer needle body includes a bend of at least 5° permanently formed along a distal end portion outer-needle body. The bend facilitates insertion of the lead introducer into an epidural space of a patient. The outer-needle body defines an open channel extending along an entire length of the outer-needle body. An inner needle is slidable along the open channel of the outer needle. The inner needle includes an inner-needle body that defines a lumen extending along an entire length of the inner-needle body. A splittable member is disposable over the outer needle when the inner needle is disposed in the open channel of the outer needle. The splittable member is separatable from the inner and outer needles along at least one perforated region.
