This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,243.

Summary of the Inventive Concept

The present inventive concept discloses improved systems and methods for treating prostate cancer using heated condensable vapor, incorporating real-time temperature control and feedback mechanisms to ensure more precise and efficient ablation of cancerous tissue.

Background and Problem Solved

The original patent for systems and methods for treating prostate cancer using heated condensable vapor has limitations in terms of temperature control and monitoring, which can lead to inconsistent ablation results and potential damage to surrounding tissue. The present inventive concept addresses these limitations by introducing real-time temperature control and feedback mechanisms to ensure more precise and efficient ablation of cancerous tissue.

Detailed Description of the Inventive Concept

The inventive concept comprises a vapor delivery device with a temperature control mechanism for adjusting the temperature of the vapor delivered to the prostate tissue, a sensor for monitoring the temperature of the prostate tissue during treatment, and a feedback loop for adjusting the temperature of the vapor based on the monitored temperature. This allows for real-time adjustments to ensure optimal ablation conditions. Additionally, the system can include a pressure sensor to monitor the pressure of the vapor during delivery and a cooling system to cool the vapor delivery device during treatment. The inventive concept also encompasses methods for ablating prostate tissue, including delivering heated vapor through a trans-urethral vapor delivery device and monitoring the impedance of the prostate tissue during treatment to adjust the delivery of vapor.

Novelty and Inventive Step

The present inventive concept introduces the novelty of real-time temperature control and feedback mechanisms, which are not present in the original patent. This allows for more precise and efficient ablation of cancerous tissue, reducing the risk of damage to surrounding tissue. The inventive step lies in the integration of temperature control, sensing, and feedback mechanisms to create a more sophisticated and effective system for treating prostate cancer.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of sensors or temperature control mechanisms, or incorporating additional features such as simultaneous cooling treatment to the urethra to reduce discomfort during treatment. Variations of the system could also be designed for treating other types of cancer or tissue.

Potential Commercial Applications and Market

The present inventive concept has significant commercial potential in the medical device industry, particularly in the field of prostate cancer treatment. The improved systems and methods could be marketed to hospitals, clinics, and medical professionals, offering a more effective and efficient solution for treating prostate cancer.
