1. An apparatus for providing electroporation therapy for benign prostatic hyperplasia, said apparatus comprising:
- a urethral applicator configured for insertion into a urethra, said applicator including;
a substantially hollow probe, said probe portion including first, second and third probe portions, said first probe portion being configured for insertion into the penile urethral segment and said third probe portion being configured for insertion into the prostatic urethral segment, said first and third probe portions defining first and second probe portion longitudinal axes, wherein said axes are not collinear with each other and wherein said second probe portion lies between said first and third probe portion;
a handle, said handle being attached to said probe;
a plurality of needle electrodes, said electrodes being mounted within said first probe portion for reciprocal movement into and out of said first probe portion substantially parallel to the urethra, said electrodes being provided for connection to an electric pulse generator;
wherein when said applicator is disposed in operating position, said needle electrodes may be advanced into benign prostatic hyperplasia tissue for electroporation therapy.

15. A method of providing electroporation therapy for benign prostatic hyperplasia comprising:
-
providing an applicator including a probe having a proximal probe portion and a distal probe electrode portion, said portions each defining non-collinear longitudinal axes, said probe including at least one electrode for electroporation therapy;
inserting the applicator into a patient'"'"'s urethra to dispose the distal probe portion in the prostatic urethral segment and the proximal probe portion in the penile urethral segment and to displace the patient'"'"'s prostate gland sideways relative to the proximal probe portion;
advancing at least a first electrode into the benign prostatic hyperplasia tissue; and
applying electric pulses to the distal probe electrode portion and the at least first electrode to generate electroporating electric fields. - View Dependent Claims (16)
