System and method for detecting perforations in a body cavity

A method of treating a body cavity, comprising the steps of:

• (a) inserting a medical device into a body cavity;
• (b) using a pressure sensor fluidly coupled to the medical device, monitoring for the presence of a perforation in the body cavity;
• and
• (c) using the medical device, treating the interior of the body cavity.

A system for detecting the presence of a perforation in a body cavity, the system including:

• a source of inflation medium;
• a medical device insertable into a body cavity, the medical device fluidly coupled to the source of inflation medium for delivery of inflation medium into the body cavity;
• a pressure sensor positioned to detect a pressure of the body cavity;
• and
• feedback means coupled to the pressure sensor to provide feedback to a user if the pressure monitored by the pressure sensor fails to rise and remain above a predetermined level during a predetermined amount of time.

A system for detecting the presence of a perforation in a body cavity and for treating the interior of the body cavity, the system including:

• a souci of inflation medium;
• a medical device insertable into a body cavity, the medical device fluidly coupled to the source of inflation medium for delivery of inflation medium into the body cavity, the medical device including a treatment element for treating the interior of a body organ;
• a pressure sensor positioned to detect a pressure of the body cavity;
• determining means coupled to the pressure sensor to determine whether pressure monitored by the pressure sensor fails to rise and remain above a predetermined level during a predetermined amount of time.
