1. A constraining sheath comprising:
an inverted sheath having an inner layer and an outer layer, the layers at least partially defining a chamber;
a restraining member fitted between the inner layer and the outer layer of the inverted sheath; and
a medical device covered by or contained in the inverted sheath in a first profile;
wherein the chamber of the inverted sheath is pressurizable via introduction of fluid into the chamber, the inverted sheath is evertable and retractable along the medical device by foreshortening of the inverted sheath to assume a second profile in response to pressurizing the chamber, and the restraining member is movable in a proximal direction in response to everting the inverted sheath.
