Patent ID: 8715251

Claim:
A surgical access port comprising: a longitudinal axis; an instrument access channel extending from a proximal and to a distal end thereof and substantially aligned with the longitudinal axis; an elongate tubular body comprising a lumen through which the instrument access channel extends, the tubular body dimensioned for traversing a body wall into a body cavity; a seal housing disposed at a proximal end of the tubular body; a blunt, tissue penetrating tip; and a retention member extending from the elongate tubular body into the tip and pivotably connecting the tip to a distal end of the tubular body, and wherein the access port has a first configuration in which the tissue penetrating tip is substantially aligned with the longitudinal axis and substantially blocks the instrument access channel, the access port has a second configuration in which the tissue penetrating tip is not aligned with the longitudinal axis and does not block the instrument access channel, advancing the access port through tissue maintains the access port in the first configuration, and the retention member biases the tip in the second configuration when no axial load is on the tip.
