A lead implanted in a body to apply electrical stimulation to body organs includes an electrode wire having one end provided as an insertion portion to be inserted into a body and another end provided as an interface portion for connection with an external device; a first electrode in the insertion portion to transmit electrical stimulation to body organs; a second electrode on the interface portion to receive electrical stimulation applied from outside; a signal line that interconnects the first electrode and second electrode to transmit electrical stimulation received by the second electrode to the first electrode; and a ring member that covers the first electrode and has an opening for exposing the first electrode in a portion of a circumferential direction, and is mounted to be movable in a longitudinal or circumferential direction with respect to the electrode wire by an external force to adjust an exposure position of the first electrode.

Lead for applying electrical stimulation to body organ, and electrode system using same

The lead implanted in a body to apply electrical stimulation to body organs may include: an electrode wire having one end provided as an insertion portion to be inserted into a body and the other end provided as an interface portion for connection with an external device to transmit a stimulation signal: a plurality of first electrodes in the insertion portion; a plurality of second electrodes on the interface portion; and a plurality of signal lines interconnecting the first electrodes and the second electrodes, wherein the insertion portion of the electrode wire includes a plurality of support portions on which the first electrodes are respectively disposed and a plurality of stretchable portions between the support portions and expandable and contractible, and further includes an operation unit for pushing or pulling each support portion in a longitudinal direction of the electrode wire to adjust a position of the support portion.

Electrode wire for applying electrical stimulation to body organs, and electrode system using same

An implantable lead having adjustable electrode locations and a system for controlling the same. The implantable lead may include a plurality of first electrodes exposed and formed at an upper part of a main body at given intervals, a plurality of second electrodes coupled to a stepped lower part of the main body and configured to deliver a stimulus signal to a core area into which the lead is inserted, and a plurality of signal lines embedded in the main body and configured to connect the first electrodes and the second electrodes in a one-to-one manner. In this case, a slot for coupling and up and down movement of the second electrodes may be formed in the lower part. As the second electrodes are individually moved along the slot by an external force acting on the signal lines, locations of the second electrodes in the lower part may be adjusted.

Implantable lead with adjustable electrode position and control system thereof

A system and method which dynamically and interactively displays information, such as advertising messages, in an intelligent artificial form by responding to a user's pointing device movement or activity. The pointing device activity by the user is analyzed in real-time and displays intended information and/or images near the pointer in real-time by employing layer technology. Other effects provided in response the pointing device movement or activity include disappearance, reappearance, dropping to the corner of the screen, etc of the information and/or image as the pointer is shook or moved in a certain shape by the user. These effects attract potential customers or clients by providing the various features disclosed in the invention under the Internet environment through web-sites.
