Apparatus for treating a target site of a body
Apparatus for performing a procedure at a target site of a patient's body, the apparatus comprising: a continuous positive airway pressure (CPAP) apparatus that provides CPAP to the patient's lungs; a medical device for performing the procedure at the target site; and a controller that controls the CPAP apparatus to provide CPAP to the patient's lungs during performance of the procedure.
1. Apparatus for performing a procedure at a target site of a patient's body, the apparatus comprising:
a continuous positive airway pressure (CPAP) apparatus adapted to provide CPAP to the patient's lungs;
a medical device adapted to perform the procedure at the target site; and
a controller configured to control the CPAP apparatus based on images provided by a medical imager to provide CPAP to the patient's lungs at a pressure and flow rate that maintains the lungs substantially fully expanded to moderate motion of the target site during performance of the procedure and determining a desired internal target volume (ITV);
wherein the procedure and maintenance of the lungs substantially fully expanded lasts for a period of time equal to or greater than about a complete breathing cycle of the patient and during the period of time provision of CPAP to the lungs is not synchronized with the patient's breathing cycle.
2. The apparatus according to claim 1 wherein the medical device comprises a radiation beam generator that generates a radiation beam for irradiating tissue at the target site.
3. The apparatus according to claim 2 wherein the radiation beam generator configures the radiation beam to irradiate the internal target volume (ITV) in the patient's body that comprises the target site.
4. The apparatus according to claim 3 and comprising the medical imager operable to provide the images of the target site.
5. The apparatus according to claim 4 wherein the controller comprises an executable instruction set that the controller executes to process the images to determine the ITV.
6. The apparatus according to claim 1 wherein the medical device comprises a tissue ablator adapted to deliver energy to tissue in the target site to ablate the tissue.
7. The apparatus according to claim 1 wherein the medical device comprises a biopsy sampler that is adapted to acquire a sample of tissue in the target site.
8. The apparatus according to claim 1 wherein the medical device comprises a catheter for cardiac catheterization.
9. The apparatus according to claim 1 wherein the medical device comprises a stent.
10. The apparatus according to claim 1 wherein the medical device comprises the medical imager operable to provide the images of the target site on which the controller bases control of the CPAP apparatus.
11. The apparatus according to claim 1 wherein the medical device comprises a robotic device controlled by the controller.
12. The apparatus according to claim 1 wherein the medical device comprises a manually operated medical device.
