System and method for sensing tissue characteristics
A medical device for treating and analyzing tissue is disclosed. The device includes a plasma applicator having a housing. The housing includes a substantially tubular shape and defining a lumen therethrough. The lumen is in fluid communication with an ionizable media source configured to supply ionizable media thereto. The applicator also includes one or more electrodes coupled to the housing. The electrodes are adapted to couple to a power source configured to that energizes electrodes to ignite the ionizable media to form a plasma plume for treating tissue. The device also includes an effluent-collection attachment coupled to the plasma applicator, the effluent-collection attachment configured to collect at least a portion of a plasma effluent.
1. A medical device for treating and analyzing tissue, the device comprising:
a plasma applicator including:
a housing having a substantially tubular shape and defining a lumen therethrough, the lumen in fluid communication with an ionizable media source configured to supply ionizable media thereto;
at least one electrode coupled to the housing, the at least one electrode adapted to couple to a power source that energizes the at least one electrode to ignite the ionizable media to form a plasma plume for treating tissue; and
an effluent-collection attachment coupled to the plasma applicator, the effluent-collection attachment configured to collect at least a portion of a plasma effluent, wherein the effluent-collection attachment includes a plurality of filters disposed therein.
2. A medical device according to claim 1 , wherein the effluent-collection attachment is in fluid communication with a negative pressure source to provide for a flow of the plasma effluent through the effluent-collection attachment.
3. A medical device according to claim 2 , wherein the effluent-collection attachment includes a housing having a substantially tubular shape and defining a lumen therethrough, the plurality of filters being disposed in the lumen of the effluent-collection attachment.
4. A medical device according to claim 3 , wherein the housing of the effluent-collection attachment is disposed concentrically relative to the housing of the plasma applicator.
5. A medical device according to claim 4 , wherein the housing of the plasma applicator includes at least one opening that provides fluid communication between the lumen of the plasma applicator and the lumen of the effluent-collection attachment allowing for the plasma plume to flow through both lumens.
