Device, system and method for pericardial access

A device for accessing a pericardial space of a subject in need thereof, the device comprising:

• a tubular member having an open ended atraumatic distal end, a proximal end, and a wall having an outer surface and an inner surface forming a lumen, wherein the tubular member and the atraumatic distal end are not movable with respect to each other;
• a thread formed on, and at least partially around, said outer surface, proximal to said atraumatic distal end, wherein said thread ends at a sharp distal tip spaced at a constant distance of between 2 and 10 mm, inclusive, from the atraumatic distal end,
• a first bio-impedance sensor positioned on the atraumatic distal end;
• and
• a second bio-impedance sensor positioned on a distal end of the thread;
• wherein said thread is configured to cut, puncture and/or penetrate a pericardium, when in use, at an essentially perpendicular and/or tangential angle relative to said longitudinal axis of said tubular member, and
• wherein the atraumatic distal end is configured to protect said subject's heart and/or myocardium from being damaged.
