Abstract:
1. A method for thermally treating a target tissue volume within the body of a patient comprising the steps of: (a) determining temperature value and treatment interval therapy data for carrying out said treatment of said target tissue volume; (b) providing an untethered implant having a discernable response condition when at a select temperature corresponding with said therapy data temperature value; (c) providing an alternating current field based heating assembly having an on state and an off state and controllable for the generation of heat at said target tissue volume from an application component located externally of said body; (d) providing a detector assembly having a pick-up component positionable externally of said body and having, when enabled, a detector output in response to said implant discernable response condition; (e) locating said untethered implant at an intra-body location effective for response to temperatures at the location of said target tissue; (f) positioning said detector assembly pick-up at a location externally of said body effective for detecting said implant discernable response condition; (g) controlling said heating assembly to elevate the temperature of said target tissue; (h) monitoring said detector assembly for the presence of said detector output corresponding with said select temperature; (i) modulating the control of said heating assembly to substantially maintain said determined temperature value in correspondence with the occurrence of said detector output; and (j) controlling said heating assembly to terminate said generation of heat at said target tissue at the expiration of said determined treatment interval.
