Abstract

The disclosed system improves urine flow by increasing the inside diameter of the urethra going through the prostate by eroding the urethral wall, rather than by reducing the prostate volume. This is done by a specially designed IRE electrode, which limits the penetration depth of the electric field to the urethral wall.

Claims

1. A system for improving the flow of urine by enlarging the inside diameter of the urethra, said enlarging done by a shallow penetration IRE system.

5. A system as in claim 1 wherein said enlarging is done by inserting a catheter into the urethra, said catheter having electrodes limiting the penetration of the electric field to less than 2 mm.

6. A system as in claim 1 wherein said shallow penetration is done by limiting the distance between the IRE electrodes to less than 2 mm.

11. A system as in claim 1 wherein said shallow penetration is limited to the urethral wall.

2. A system for treating BPH by using shallow penetration IRE system to erode the inside wall of the urethra.

3. A catheter for treating BPH by eroding the inside wall of the urethra, said catheter being inserted inside the urethra and causing a shallow layer of cells inside the urethra to die.

4. A catheter as in claim 3 wherein the cells inside the urethra are made to die by the effect of a shallow electric field.

7. A system as in claim 3 wherein said shallow layer is less than 2 mm deep.

8. A system as in claim 3 wherein said catheter has electrodes in the form of two spirals.

9. A system as in claim 3 wherein said catheter has electrodes in the form of longitudinal lines.

10. A system as in claim 3 wherein said catheter has a lumen for providing irrigation during said erosion.
