Electrode assembly for a percutaneous electrical therapy system
First Claim
1. A percutaneous electrode assembly comprising:
- a housing configured to be mounted on a patient, an electrode disposed in the housing, the electrode comprising a sharp point at a distal end configured to be inserted into a patients tissue;
an electrode actuator disposed in the housing and configured to move the sharp point of the electrode out of the housing;
an electrode electrical connector configured to electrically connect the electrode to a control unit to deliver electrical therapy to a patient; and
a limit stop limiting movement of the electrode out of the housing.

Abstract
The invention is a percutaneous electrode assembly. In a preferred embodiment, the assembly includes a housing adapted to be mounted on a patient; an electrode disposed in the housing, the electrode having an sharp point at a distal end adapted to be inserted into a patient'"'"'s tissue; an electrode actuator disposed in the housing and adapted to move the sharp point of the electrode out of the housing; and an electrode electrical connector adapted to electrically connect the electrode to a control unit to deliver electrical therapy to a patient.
The invention is also a method of inserting a percutaneous electrode into a patient. In a preferred embodiment, the method includes the following steps: placing a housing on a patient; and moving at least part of an electrode out of the housing and into the patient and connecting the electrode electrically with a control unit cable, the moving and connecting steps being performed with a single user motion.
