A seal comprises a first sealing member and a second sealing member. The sealing members each have an accessway to facilitate access from one side of the sealing member to the other side of the sealing member. The accessways are offset to facilitate sealed access of an object through the sealing members.

The Robotic Double Cannulation Cannula is a laparoscopic cannula that will be docked to the Si, X or Xi da Vinci Surgical Systems® (Intuitive, Sunnyvale Calif.) and then placed through an EndoWrist 12 mm & Stapler Cannula® (Intuitive, Sunnyvale Calif.). This provides ease of insertion and extraction of surgical materials, such as suture and mesh, along with specimen extraction, without having to undock the robotic arm. Once inserted, the Robotic Double Cannulation Cannula remote center of movement will match the remote center of movement of the EndoWrist 12 mm & Stapler Cannula® (Intuitive, Sunnyvale Calif.) to prevent injury to the abdominal wall musculature. An electrical contact on the intern tip of the Robotic Double Cannulation Cannula will provide electrical grounding to the outer cannula to prevent electrical injury.

A pad is provided having a body for providing a gas seal over a surgical site, a port extending between a first surface of the body and a second surface of the body and sized accept a surgical instrument, and a lumen situated along the body and having a first opening and a second opening, the second opening aligned with the surgical site for communicating a fluid flow to the surgical site.

A cannula mounting fixture may include a base, a first arm with a first cannula mounting bracket and a second arm with a second cannula mounting bracket. The first arm may be coupled to the base so that a first cannula mounted at the first mounting bracket is positioned within an opening in a patient's body. The second arm may be coupled to the base and includes a joint that allows a second cannula mounted at the second mounting bracket to be inserted through the opening. A cannula stabilizing fixture may include a base and a repositionable arm. The base may be configured to be securely and removably coupled to a first cannula that extends into an opening in a patient's body. The repositionable arm may include a first cannula holder coupled to the base and is configured to support a second cannula that extends into the opening.

Methods and devices described herein facilitate improved treatment of body organs. More specifically, devices and methods described herein are for minimally invasive surgery permit improved diaphragmatic access to a body cavity to perform a surgical procedure, for example ablation and/or coagulation of cardiac tissue during minimally invasive surgical access to the heart. The diaphragmatic access described provides direct visualization of anatomic structures within the thoracic cavity such as the posterior left atrium, the posterior side of pulmonary veins, or any other such anatomic structure.

A system for performing an endoscopic surgical procedure in a surgical cavity of a patient that includes a gas delivery device configured to deliver a flow of pressurized gas to a gas delivery lumen extending therefrom, a gaseous sealing module communicating with a distal end of the gas delivery lumen and configured to generate a gaseous seal within a gas sealed lumen extending therefrom, and an access port communicating with a distal end of the gas sealed lumen so as to provide sealed instrument access to the surgical cavity and maintain a stable pressure within the surgical cavity.

An anti-reverse apparatus includes a latch capable of stopping an end sealing piece from moving reversely, and a loose switch capable of relieving a stop action by the latch on the reverse movement of the end sealing piece. Limitation of the latch on the reverse movement of the end sealing piece can be relieved by pressing the loose switch down. When the end sealing piece is detachably mounted at a near end of a sleeve in a rotating manner, the latch can stop reverse movement causing loosening of the end sealing piece and prevent air leakage or the end sealing piece from loosening from the near end of the sleeve. When the loose switch is pressed down, limitation of the latch on the reverse movement of the end sealing piece can be relieved, and the end sealing piece can be detached from the near end of the sleeve.

A vessel harvesting apparatus for removing a blood vessel from a patient includes collection and conditioning (i.e., treatment) of expelled insufflation gas prior to releasing the gas into the air of the operating room. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. An insufflation channel is configured to convey an insufflation gas subcutaneously into a dissected space within the patient. A removal channel is configured to evacuate fluidic contents from the dissected space, wherein the fluidic contents include insufflation gas and biological impurities. A processor/separator is coupled to the removal channel to process the fluidic contents to retain at least some of the biological impurities and to exhaust the insufflation gas.

A device, system, kit, and method for managing the passage of fluid through an opening in the body of a patient that includes a fluid-containment receptacle including a collapsible sidewall, the fluid-containment receptacle having a first receptacle opening and a second receptacle opening positioned at opposite ends of the sidewall, the fluid-containment receptacle. The device also including a first flange extending radially outward from the sidewall and positioned at or adjacent to the first receptacle opening and a second flange extending radially outward from the sidewall at or adjacent to the second receptacle opening. The device is configured to be applied to the opening in the body of the patient such that the first opening and the first flange contact the body of the patient and form a fluid barrier around the opening.

Disclosed herein are multiple cannulas defining a lumen sized and dimensioned to receive one or more medical instruments, an inflatable outer membrane attached to an outer surface of the cannula, and at least one activator that reversibly pressurizes a fluid contained in the outer membrane to fill or pressurize the outer membrane.
