8. A surgical device, comprising:
a housing including a first predefined elongate path formed therein and including a second predefined elongate path formed therein, and the housing being configured to have first and second surgical instruments extending therethrough such that a distal portion of each of the first and second surgical instruments is located in a body of a patient and a proximal portion of each of the first and second surgical instruments is located outside of the body of the patient;
a first support that seats a first sealing element, the first sealing element being configured to receive the first surgical instrument therethrough and form a seal therearound, and the first sealing element being configured to move, with the first surgical instrument received therethrough, within the first predefined elongate path relative to the housing;
a second support that seats a second sealing element, the second sealing element being configured to receive the second surgical instrument therethrough and form a seal therearound, and the second sealing element being configured to move, with the second surgical instrument received therethrough, within the second predefined elongate path relative to the housing; and
a deformable membrane coupled to the housing, the deformable membrane being configured to deform in response to the movement of the first sealing element within the first predefined elongate path;
wherein the first predefined elongate path extends radially, includes a first terminal end at a position adjacent to an outer diameter of the housing, and includes a second terminal end radially inward of the first terminal end; and
the second predefined elongate path extends radially, includes a third terminal end at a position adjacent to the outer diameter of the housing, and includes a fourth terminal end radially inward of the third terminal end.
