CHRONICALLY-IMPLANTABLE ACTIVE FIXATION MEDICAL ELECTRICAL LEADS AND RELATED METHODS FOR NON-FLUOROSCOPIC IMPLANTATION |
摘要 |
Bio-impedance may be used for navigation systems to chronically implant pacing and defibrillation leads in the heart using a non-fluoroscopic position sensing unit (PSU). Such a system requires that a conductive material, such as a retractable helical tip-electrode, be exposed during implantation. Since the tip is retracted during implantation, this disclosure provides a modified distal portion employing at least one aperture (or “window”) for fluid exposure of the helix-electrode and a deployable internal sleeve for covering the aperture(s) when the helix-electrode is extended. |
