Transurethral needle ablation system with needle position indicator
First Claim
17. A transurethral ablation system comprising:
- a transurethral catheter;
an ablation needle extendable from the catheter to penetrate a prostate of a patient;
an ablation energy generator to deliver ablation energy to the prostate via the ablation needle; and
a needle position indicator to present an advisory when the needle is not fully retracted within the catheter.

Abstract
In general, the invention provides a transurethral ablation device for indicating whether the ablation needle or needles are deployed or retracted during transurethral prostate treatment. The device includes a needle position sensor and a needle position indicator. The needle position sensor can directly or indirectly determine the position of the needle. The needle position indicator can be located at the distal end of the catheter from which the needle is extended, or within the handle. The needle position indicator can be located on the handle, on the ablation energy generator or on an associated user interface. The needle position indicators can be audible indicators such as audible advisories, warnings, or alarms, or visual indicators such as lights, colored lights, flashing lights, graphical images or text messages.

43-1. The transurethral ablation system of claim 42, further comprising:
-
means for repositioning the ablation means within the prostrate such that the ablation means is aligned with a second target tissue site within the prostrate; and
wherein the ablation means is further for delivering the ablation energy to the second target tissue site.

50. A computer-readable medium containing instructions for causing a processor to:
-
control delivery of ablation energy to a target tissue site within a prostate of a patient via an ablation needle extended from a transurethral catheter deployed within the target tissue site;
receive an ablation needle position signal indicative of a position of the ablation needle within the catheter;
activate an advisory if the ablation needle position signal indicates that the position of the ablation needle is not fully retracted within the catheter after delivery of the ablation energy; and
continuously activate the advisory until the ablation needle position signal indicates that the position of the ablation needle is fully retracted within the catheter.
