Surgical access assembly having a button inflator

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

• actuating a button disposed on a collar of the surgical access assembly between a first check valve and a second check valve;
• supplying air to the balloon anchor;
• and
• maintaining air pressure in the balloon anchor.

A surgical access assembly, comprising:

• a balloon cannula including:
• an elongated cannula member having proximal and distal end portions;
• a cannula housing having an outer sleeve, the cannula housing coupled to the proximal end portion of the elongated cannula member;
• a balloon anchor formed with the outer sleeve and 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 outwardly from the elongated cannula member, the port configured having a first end portion and a second end portion;
• a first check valve disposed between the first end portion of the port and the second end portion of the port, wherein the first check valve and the port define a first chamber;
• a second check valve coupled to the second end portion of the port, wherein the second check valve and the port define a second chamber between the second check valve and the first check valve;
• an actuatable button configured to control flow of air into the balloon anchor;
• and
• a release valve configured to control flow of air out of the balloon anchor.
