Abstract
An electrocautery probe for penetrating through tissue. The probe comprises a tissue-compatible, flexible sleeve; an exposed electrode carried at one end of the sleeve; a wire connected at one end to the electrode and extending through the sleeve; and an electrical connector attached to the other end of the wire. The connector is suitable for attachment to a source of electrocautery power. The wire is separate from the sleeve, to be removable by pulling from the sleeve when the electrode is cut away or otherwise removed from the sleeve. Thus, the probe can penetrate tissue by electrocautery action to form a tissue tunnel, and the electrode and wire can then be removed, leaving at least a portion of the sleeve in the tissue tunnel to serve as a drainage catheter.
