Abstract:
1. A surgical access device comprising a visual insufflation obturator comprising: an elongate body having an open proximal end, an open distal end and a body lumen extending from the proximal end of the elongate body to the distal end of the elongate body along a longitudinal axis of the elongate body; a handle connected to the proximal end of the elongate body; a transparent bladeless tip without cutting edges, the tip connected to and closing the open distal end of the elongate body and having an enclosed distal end and a tip cavity and a tissue separating outer surface with a fixed aperture extending through the outer surface into the tip cavity; and a micro-seal located proximal the enclosed distal end and within the aperture of the tip between the outer surface of the tip and the tip cavity, wherein the micro-seal is normally closed preventing flow through the aperture and opens under pressure of insufflation gas to allow flow through the aperture; wherein the aperture and the micro-seal are positioned close to a most distal portion of the tip to prevent interference with a viewing path of a laparoscope inserted inside the body lumen.
