SYSTEM AND METHOD FOR SENSING TISSUE CHARACTERISTICS Abstract 5 A medical device (200) for treating and analyzing tissue is disclosed. The device (200) includes a plasma applicator (202) having a housing (206). The housing (206) includes a substantially tubular shape and defining a lumen (208) therethrough. The lumen (208) is in fluid communication with an ionizable media source (16) configured to supply ionizable media thereto. The applicator (202) also includes one or more electrodes 10 (1 10a, IOb) coupled to the housing (206). The electrodes (1 Oa, 100b) are adapted to couple to a power source (14) configured to that energizes electrodes (1 10a, I 10b) to ignite the ionizable media to form a plasma plume for treating tissue. The device (200) also includes an effluent-collection attachment (204) coupled to the plasma applicator (202), the effluent-collection attachment (204) configured to collect at least a portion of a is plasma effluent (31). 20--- 14-", 22--- 24-- SIGNAL MATCHING 2 w" GENERATOR -NETWORK 1NIZABLE M EDIA AP L ..CA T SOURCE -50 31 16- COMPUTING -- SPECTROMETER -- NEGATIVE PRESSURE DEVICE SOURCE 19 -, 15-- 17- 108a 108b 110b 110a
