The retrieval probe includes an elongated member (106) that extends between a proximal end (102) and a distal end (104), an inner core (107) disposed within the lumen of the elongated member (106), and a magnetic tip (110) disposed at the distal end (104) of the elongated member (106). The elongated member (106) includes a hollow section (142) disposed between the distal end of the elongated member and a distal end of the stiff inner core. The hollow section may be flexible and can be configured to bend at an angle of about 180 degrees. The system for securing a nasal tube includes a bridle (202) having a magnetic connection portion (204); and a retrieval probe (100) as described above. The magnetic connection portion of the bridle and the magnetic tip (110) of the retrieval probe can be configured to magnetically couple during a procedure for inserting the bridle in a nasal passageway of a patient.

摘要： A method of treating tissue of a patient's body includes providing a power source coupled to at least one probe assembly. The probe assembly includes an elongate member with a distal region and a proximal region. The distal region has an electrically and thermally-conductive energy delivery device for delivering one of electrical and radiofrequency energy to the patient's body. The electrically and thermally-conductive energy delivery device has one or more internal lumens for circulating a cooling fluid therethrough and an electrically and thermally-conductive protrusion having a temperature sensing element. The temperature sensing element extends from a distal end of the energy delivery device. The method includes inserting the energy delivery device of the at least one probe assembly into the patient's body. Further, the method includes routing the energy delivery device of the at least one probe assembly to the tissue of the patient's body. The method also includes simultaneously circulating the cooling fluid through the one or more internal lumens via at least one pump assembly and delivering energy from the power source to the tissue through the energy delivery device. Further, the method includes monitoring one or more procedure parameters while delivering the energy from the power source to the tissue through the energy delivery device. Moreover, the method includes determining, in real-time, whether a rising impedance event is likely to occur in a predetermined time period based on the one or more procedure parameters and determining a command for the pump assembly based on whether the rising impedance event is likely to occur in the predetermined time period.
