Abstract
A device useful for accessing the left atrium is provided. The device comprises an elongated tubular body and a dilating tip. The tubular body has an axis, a proximal end, a distal end and a lumen longitudinally extending therethrough. The dilating tip is slidably mounted on the distal end of the tubular body. The dilating tip comprises a segmented surface that is generally transverse to the axis of the tubular body, and a generally rigid tube extending distally from the segmented surface and having a sharp distal end. Distal movement of the tubular body relative to the dilating tip exerts a force on the segmented surface to thereby open the segmented surface.
