    摘要: 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.

    摘要: An apparatus and method for use in performing ablation of organs and other tissues includes a radio frequency generator which provides a radio frequency signal to ablation electrodes. The power level of the radio frequency signal is determined based on the subject area of ablation. The radio frequency signal is coupled with the ablation electrodes through a transformation circuit. The transformation circuit includes a high impedance transformation circuit and a low impedance transformation circuit. The high or low impedance transformation circuit is selected based on the impedance of the ablation electrodes in contact with the subject tissue. Vacuum level, impedance level, resistance level, and time are measured during ablation. If these parameters exceed determinable limits the ablation procedure is terminated.

    摘要: A uterine length measurement device includes a first elongate member having a distal end, a proximal end, and a lumen, the elongate member configured for insertion into an endocervical canal where the distal end is configured for insertion to approximately an internal cervical os of the endocervical canal. A second elongate member is provided having a distal end and a proximal end, the second elongate member configured to move within the lumen of the first elongate member, where the distal end can protrude from the distal end of the first elongate member and is configured for insertion to approximately the fundus of a uterine cavity. Moving the second elongate member relative to the first elongate member to position the distal end of the second elongate member at approximately the fundus of the uterus provides a direct measurement of a length of the uterine cavity.

    摘要: A medical device and procedure for delivering a drug into a uterus are described. In one implementation, the medical device includes a first elongate member, a second elongate member and a stopper device. The first elongate member is configured for transcervical insertion into the uterus and includes a lumen extending therethrough. The second elongate member is positioned within said lumen and also includes a lumen therethrough. The second elongate member is positionable in a retracted or an extended position. A distal end of the second elongate member is configured to extend beyond a distal end of the first elongate member and penetrate uterine tissue when in the extended position. A proximal end of the second elongate member is configured to receive a drug for delivery through the lumen of the second elongate member. The stopper device controls movement of the second elongate member within the first elongate member.
