Abstract
A vapor delivery needle is provided that may include any of a number of features. One feature of the energy delivery probe is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, or denature tissues of the prostate. Methods associated with use of the energy delivery probe are also covered.
Claims17
A medical device comprising:
- a needle;
- a first electrode disposed at a distal tip of the needle, wherein the first electrode is configured to measure a first electrical impedance of a first tissue contacting the first electrode, and wherein the distal tip of the needle is the first electrode;
- a second electrode disposed on the needle, proximally of the first electrode, wherein the second electrode is configured to measure a second electrical impedance of a second tissue contacting the second electrode;
- and
- an electrically insulative material disposed between the first electrode and the second electrode;
- and
- an electronic controller configured to use the first electrical impedance and the second electrical impedance in order to determine whether the first electrode and the second electrode are disposed within a prostate.

A medical device comprising:
- a needle terminating in a distal tip, wherein the distal tip is a first electrode configured to measure a first electrical impedance of a first tissue contacting the first electrode, the needle including:
- a second, ring electrode, proximal of the first electrode, configured to measure a second electrical impedance of a second tissue contacting the second electrode;
- and
- an electrically insulative material disposed between the first electrode and the second electrode;
- and
- an electronic controller configured to use the first electrical impedance and the second electrical impedance in order to determine whether the first electrode and the second electrode are disposed within a prostate.
3 more elements
A medical device comprising:
- a needle terminating in a distal tip, wherein the distal tip is a first electrode configured to measure a first electrical impedance and a first phase shift of a first tissue contacting the first electrode, the needle including:
- a second electrode, proximal of the first electrode, configured to measure a second electrical impedance and a second phase shift of a second tissue contacting the second electrode;
- and
- an electrically insulative material disposed between the first electrode and the second electrode;
- and
- an electronic controller configured to use the first electrical impedance, the first phase shift, the second electrical impedance, and the second phase shift, in order to determine whether the first electrode and the second electrode are disposed within a prostate.
