Abstract
A vapor delivery system is provided that may include any of a number of features. One feature of the vapor delivery system is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, or denature the prostate. In some embodiments, the vapor delivery system can include safety features including needle tracking and treatment tracking. Biopsy systems for obtaining biopsy tissue samples from the prostate are also provided. Methods for safe and effective treatment of prostate tissues and obtaining prostate biopsy samples are also presented.
Claims21
A method, comprising:
- obtaining a first medical image of a prostate including target tissue region and an anatomical landmark;
- measuring a separation distance and clock angle between the target tissue region and the anatomical landmark;
- imaging the anatomical landmark under real-time ultrasound imaging;
- advancing a needle position of a vapor delivery device transurethrally to the anatomical landmark under the real-time ultrasound imaging;
- further advancing and rotating the needle position of the vapor delivery device transurethrally by the separation distance and clock angle;
- and
- deploying a needle of the vapor delivery device from the needle position through the urethra, into the prostate, and into the target tissue region.
A medical device gps tracking system, comprising:
- a trans-rectal ultrasound imaging system (TRUS) probe configured to obtain one or more ultrasound images of a target tissue in an imaging plane;
- a plurality of sensors disposed on or within the TRUS probe, the plurality of sensors being configured to receive signals from one or more transmitters positioned on a medical device and within the imaging field of view;
- and
- control electronics configured to determine a position of the one or more transmitters from the received signals and communicate position data of the medical device for real time display on the one or more ultrasound images.
A medical system, comprising:
- a therapy device configured for transurethral access to a patient's prostate, the therapy device having a deployable needle configured to be actuated from a delivery configuration to a deployed configuration and one or more transmitters disposed thereon;
- a trans-rectal ultrasound imaging system (TRUS) probe;
- a plurality of sensors disposed on or within the TRUS probe, the plurality of sensors being configured to receive signals from the one or more transmitters;
- control electronics configured to determine a position the one or more transmitters from the received signals and communicate position data to the TRUS probe;
- and
- a display configured to display real-time images of the prostate from the TRUS probe overlaid with the position of the one or more transmitters.
