1. A method of penetrating a body tissue of a living body, comprising:

  • advancing a distal end of an elongated tubular member into a living body, the member configured to slideably receive an inner core, wherein a distal end of the inner core is disposed within the tubular member;

    rotating the inner core of the elongated member radially around a longitudinal axis;

    advancing the distal end of the inner core past the distal end of the member such that an imager located at the distal end of the inner core is placed into contact with a body tissue, wherein the body tissue comprises skin or cerebral ventricle membrane; and

    penetrating the body tissue skin or cerebral ventricle membrane with the imager by rotating the inner core and the imager at the distal end of the inner core wherein penetration is effected by rotation and axial force and wherein the imager is configured to penetrate by a process consisting of applying axial force while rotating the imager.
