Abstract: A medical probe apparatus comprising a catheter having a stylet guide housing with one or more stylet ports therein and stylet guides for directing one or more flexible stylets outward through respective stylet ports and through intervening tissue to target tissue. The active stylets emit radio frequency RF energy which establishes an RF current in the patient. The current, being densest at the stylet tips, causes heating of the surrounding tissue to initiate ablation of the target tissue. One aspect of the invention includes temperature sensing stylets at the location of the RF emitting stylets to monitor the temperature of the tissue being ablated. This allows the surgeon to have increased knowledge about the abating action under way in order to control the intensity of the applied RF current, or to adjust the amount of time the current is applied, or both. Further included herein is a plurality of temperature sensors mounted on an ultrasound probe to be used to monitor tissue temperature at the ultrasound probe while allowing the ultrasound device to monitor the position and orientation of the medical probe apparatus of the present invention.

Abstract: A medical probe device including a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radio frequency electrode. During the ablation operation, the tissue immediately adjacent the stylet can become desiccated, thereby necessitating an increase of current flow and a loss of ablation efficiency. A forward and reverse movement of the non-conductive sleeve on the stylet during an operation frees the stylet from sticking tissue and creates a space around the electrode to allow the tissue to rehydrate.

Abstract: A medical probe apparatus comprising a catheter having a stylet guide housing with one or more stylet ports therein and stylet guides for directing one or more flexible stylets outward through respective stylet ports and through intervening tissue to target tissue. The active stylets emit radio frequency RF energy which establishes an RF current in the patient. The current, being densest at the stylet tips, causes heating of the surrounding tissue to initiate ablation of the target tissue. One aspect of the invention includes temperature sensing stylets at the location of the RF emitting stylets to monitor the temperature of the tissue being ablated. This allows the surgeon to have increased knowledge about the abating action under way in order to control the intensity of the applied RF current, or to adjust the amount of time the current is applied, or both. Further included herein is a plurality of temperature sensors mounted on an ultrasound probe to be used to monitor tissue temperature at the ultrasound probe while allowing the ultrasound device to monitor the position and orientation of the medical probe apparatus of the present invention.

Abstract: A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a stylet guide for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue. It can also include a fiber optic cable for laser treatment. The catheter can include one or more inflatable balloons located adjacent to the stylet port for anchoring the catheter or dilation. Ultrasound transponders and temperature sensors can be attached to the probe end and/or stylet. The stylet guide can define a stylet path from an axial orientation in the catheter through a curved portion to a lateral orientation at the stylet port.

Abstract: A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a stylet guide for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue. It can also include a fiber optic cable for laser treatment. The catheter can include one or more inflatable balloons located adjacent to the stylet port for anchoring the catheter or dilation. Ultrasound transponders and temperature sensors can be attached to the probe end and/or stylet. The stylet guide can define a stylet path from an axial orientation in the catheter through a curved portion to a lateral orientation at the stylet port.
