1. A method of ablating a tissue region using an ablation device, comprising:

  • a) providing an ablation device comprisinga proximal region, a central region and a distal region, the distal region comprising an antenna configured to delivery ablation energy,at least one stick region positioned within said central region and/or the proximal region and configured to attain and maintain a temperature causing freezing of tissue to facilitate adhering of the tissue to the stick region in order to stabilize the ablation device in a desired position with respect to a tissue region during ablation, anda seal positioned between the stick region and the distal region thereby preventing exposure of the stick region to the distal region,b) positioning the ablation device in the vicinity of a tissue region,c) adhering the ablation device to the tissue by reducing temperature of the stick region, andd) delivering energy to the tissue region while the ablation device is adhered to the tissue.
