摘要:
The computer system is capable of acquiring and displaying images of the prostate of a patient for assisting a surgeon in placing ablative elements in the prostate of the patient. The computer system is programmed with software capable of: 1) determining the dimensions of the prostate; and, 2) determining the dimensions and location of a treatment zone. The treatment zone is determined to include only one neurovascular bundle of the prostate and exclude the other neurovascular bundle of the prostate. The system utilizes the determined dimensions of the prostate and treatment zone for computing the number and location of ablative elements needed to treat the treatment zone while minimizing any adverse effect on the patient's sexual function.
摘要:
The system for providing computer guided ablation of tissue of a patient includes an imaging device, an ablative surgical computer system, and a set of surgical devices. The imaging device receives imaging data from a treatment region of a patient, processes the imaging data and provides imaging output data and imaging signals. The imaging output data is available to an operator. The ablative surgical computer system includes a guidance module for processing the imaging signals and providing a treatment guidance plan to the operator; and, a treatment module for acquiring and processing surgical device output data, for optimally controlling treatment parameters and providing feedback information to the operator based on the treatment guidance plan. The set of surgical devices includes at least one integrated ablative/temperature sensing device including at least one ablative device for providing ablation of the treatment region based on the treatment parameters and operator input; and, at least one temperature sensing device for acquiring temperature data from the treatment region and providing a temperature sensing device output signal. The temperature sensing device output signal is a portion of the surgical device output data. The treatment guidance plan is utilized for placing the integrated ablative/temperature sensing device into the treatment region.

摘要:
A stent delivery system for use in placing a stent within the prostatic urethra and ensuring that the stent does not interfere with the closure of the bladder neck sphincter. The delivery system includes a catheter with an anchor which anchors the catheter within the urethra and ensures placement of the stent at a predetermined distance from the bladder neck sphincter. For use with shape memory stents, the catheter includes a warming fluid system in which the endoscope used in the procedure can act as a fluid supply line and as valve spool to control the flow or warming fluid to the stent.
摘要:
A system for assisting surgeons in performing cryosurgery of the prostate by calculating optimal positions for cryoprobes and providing display based templates for overlay over an ultrasound image display, and displaying actual cryoprobe ultrasound images together with template images so that the surgeon may compare suggested and actual placement of the cryoprobes, and adjust placement accordingly.
摘要:
The present invention is a system for placing cryoprobes in a treatment area of a human patient. The system includes a computer system for displaying an image of a treatment area, a template of suggested cryoprobe palcements in the treatment area and images of actual cryoprobes placed within treatment area. The computer system is programmed to perform the steps of: acquiring the image of the treatment area, determining desired dimensions of the treatment area based on the image of the treatment area, determining the optimal cryoprobe placements in the treatment area based on the determined desired dimensions to provide the template of suggested cryoprobe placement, acquiring the images of actual cryoprobes placed within the treatment area, and overlaying the template of suggested cyroprobe placements on the acquired images of actual cryoprobes. The resulting overlaying is provided on a display of the computer system, thereby allowing the surgeon to compare the actual cryoprobe palcements with the optimal cryoprobe placements as determined by the computer system.
