1. A system, comprising a microwave ablation device comprising a proximal region, a central region and a distal region, the distal region comprising an antenna configured to deliver microwave 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 microwave ablation device in a desired position with respect to a tissue region during microwave ablation;a seal positioned between the stick region and the distal region thereby preventing exposure of the stick region to the distal region;a processor comprising processor software configured for operating the microwave ablation device; andsoftware configured to interact with the processor, wherein the software is configured to provide a drawn desired ablation zone based upon inputted information associated with a tissue region. 2. The system of claim 1, wherein the ablation device further comprises one or more coolant tubes or channels configured to deliver coolant to the stick region and/or the antenna. 3. The system of claim 2, wherein the processor is configured to circulate coolant through the one or more coolant tubes or channels. 4. The system of claim 1, wherein the antenna comprises a coaxial transmission line. 5. The system of claim 1, wherein the antenna comprises a tri-axial antenna transmission line. 6. The system of claim 1, wherein the distal region and central region are separated by a plug region. 7. The system of claim 6, wherein the plug region is configured to prevent cooling of the distal region resulting from cooling of the central region. 8. The system of claim 1, wherein the inputted information is one or more of the following types of information: type of the tissue region, location of the tissue region, location of vascular vessels associated with the tissue region, location of vulnerable structures associated with the tissue region, blood flow information associated with the tissue region. 9. The system of claim 1, wherein the software is configured to adjust the drawn desired ablation zone in real time during a procedure based upon additional inputted information, wherein the additional inputted information is one or more of changes in temperature of the microwave ablation device, changes in temperature of the tissue region, changes in size of the tissue region, and changes in vascularity associated with the tissue region. 10. The system of claim 1, wherein the processor is configured to operate the microwave ablation device such that the microwave ablation device ablates a tissue region consistent with the drawn desired ablation zone. 11. The system of claim 1, wherein the processor is configured to deliver coolant to the stick region for purposes of freezing the tissue to facilitate adhering of the tissue to the stick region. 12. The system of claim 1, wherein the processor is configured to circulate coolant to the central and/or distal region of the microwave ablation device upon user activation of the microwave ablation device. 13. A system, comprising a microwave ablation device comprising a proximal region, a central region and a distal region, the distal region comprising an antenna configured to deliver microwave 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 microwave ablation device in a desired position with respect to a tissue region during microwave ablation; anda processor comprising processor software configured for operating the microwave ablation device, wherein the processor is configured to regulate the amount of microwave energy provided to a tissue region through the microwave ablation device, wherein the regulation of the amount of microwave energy provided to a tissue region is accomplished through monitoring one or more of the following: changes in temperature of the microwave ablation device, changes in temperature of the tissue region, changes in size of the tissue region, changes in shape of the tissue region, and changes in vascularity associated with the tissue region. 14. The system of claim 13, wherein the monitoring is in real time.
