1. A dilator access sheath, comprising:
a body extending between a proximal end and a distal end, the body having:
a lumen extending between the proximal end and the distal end;
an expandable element; and
a flexible membrane;
wherein the body is biased, absent the application of any force, towards a non-expanded configuration, and wherein the body is configured to move to an expanded configuration via insertion of a device within the lumen of the body.
