A method of inflating and deflating a balloon anchor of a surgical access assembly comprising:

• actuating a pump coupled to a first check valve of the surgical access assembly;
• supplying air to the balloon anchor;
• and
• maintaining air pressure in the balloon anchor.

A surgical access assembly, comprising:

• a balloon trocar including:
• an elongated cannula member having proximal and distal end portions;
• a cannula housing having an outer sleeve, the cannula coupled to the proximal end portion of the elongated cannula member;
• a balloon anchor coupled to the distal end portion of the elongated cannula member;
• and
• a collar disposed along the elongated cannula member and in fluid communication with the balloon anchor, the collar including:
• a port extending outward from the elongated cannula member, the port configured to receive a first check valve configured to control flow of air into the balloon anchor;
• a manually actuatable pump coupled to the first check valve;
• and
• a release valve coupled to the port and configured to control flow of air out of the balloon anchor.
