Medical devices for use in the creation of a temporary pneumoperitoneum

A method, comprising:

• placing a rigid dome at a surgical site with a patient interface of the rigid dome surrounding the surgical site;
• coupling a vacuum source to a vacuum port of the rigid dome;
• engaging a vacuum pressure regulator to provide a first vacuum pressure at an interior of the rigid dome to provide a first level of lift of the surgical site within the interior of the rigid dome;
• engaging the vacuum pressure regulator to provide a second vacuum pressure at the interior of the rigid dome to provide a second level of lift of the surgical site to draw the surgical site more fully into the interior of the rigid dome;
• inserting a medical apparatus into the interior of the rigid dome from an exterior of the rigid dome through a septum disposed in an aperture of the rigid dome;
• inserting the medical apparatus into the surgical site to deliver a gas below a surface of the surgical site to form a temporary pneumoperitoneum;
• normalizing pressure within the rigid dome;
• removing the rigid dome from the surgical site;
• forming, by a vacuum bypass compatible with the vacuum port, a barrier at the vacuum port to resist plugging of the vacuum port by the surgical site, wherein the vacuum bypass is disposed within the vacuum port and interacts with the surgical site at the vacuum port to maintain fluid flow from the rigid dome and through the vacuum port without occupying space within the rigid dome;
• and
• accepting, by a regulator port formed in the rigid dome separate from the vacuum port, the vacuum pressure regulator.

A system, comprising:

• a medical apparatus configured to be inserted at a surgical site;
• a rigid dome configured to admit the medical apparatus through a septum into an interior of the rigid dome to allow the medical apparatus to be inserted at the surgical site, wherein the rigid dome comprises:
• a viewing window disposed in the rigid dome, wherein the viewing window is optically and/or acoustically transparent;
• and
• a vacuum source configured to connect to a vacuum port of the rigid dome to reduce a pressure within the rigid dome and lift the surgical site into the interior of the rigid dome for insertion of the medical apparatus at the surgical site;
• a vacuum bypass compatible with the vacuum port to form a barrier at the vacuum port to resist plugging of the vacuum port by the surgical site, wherein the vacuum bypass is disposed within the vacuum port and interacts with the surgical site at the vacuum port to maintain fluid flow from the rigid dome and through the vacuum port without occupying space within the rigid dome;
• and
• a regulator port formed in the rigid dome separate from the vacuum port, wherein the regulator port is configured to accept a vacuum pressure regulator coupled to the rigid dome.
