System and method for detecting perforations in a body cavity
DC CAFCFirst Claim
1. A method of ablating a uterus, comprising the steps of:
- inserting an ablation device into a uterus;
flowing an inflation medium into the uterus;
monitoring for the presence of a perforation in the uterus using a pressure sensor; and
treating the interior of the uterus using the ablation device.

Abstract
A system and method for detecting perforations in a body cavity. In accordance with the method of the invention, a fluid (liquid or gas) is delivered into a body cavity to slightly pressurize the cavity. A pressure sensing system monitors the pressure within the cavity for a predetermined test period. If cavity pressure is not substantially sustained during the test period, the physician is alerted to further assess the cavity for perforations before initiating treatment within the cavity. In a preferred form of the system, a medical treatment system such as an RF ablation system is provided with perforation detection functionality. The system preferably includes a pre-test and post-test lockout system. The lockout system prevents RF power delivery unless, during a predetermined test period, the pressure sensing system determines that no perforation exists, or unless a previously performed perforation detection procedure determined a perforation was present but the lockout system was subsequently overridden by the physician.

9. A method of detecting a perforation in a uterus, comprising the steps of:
-
passing an inflation medium into the uterus;
monitoring for the presence of a perforation in the uterus using a pressure sensor;
if no perforation is detected during the monitoring step, permitting ablation of the uterus using an ablation device; and
if a perforation is detected during the monitoring step, preventing ablation of the uterus. - View Dependent Claims (10, 11, 12, 13, 14, 15)
