Abstract

A method of dissecting tissue includes inserting a magnetized catheter into a urethra; magnetically pushing a tool away from the urethra with the magnetized catheter; and dissecting tissue posterior of the urethra with the tool.

First claim

What is claimed is:

1 . A method of dissecting tissue, the method comprising:
inserting a catheter into a urethra with a portion of the catheter magnetized to a first polarity; providing a tool with a tissue dissection area, where the tissue dissection area of the tool is magnetized to a same polarity as the first polarity; and repelling the tissue dissection area of the tool away from the catheter in the urethra and dissecting tissue posterior of the urethra with the tissue dissection area of the tool.

2 . The method of claim 1 , further comprising:
forming an access path posterior of the urethra with the tool.

3 . The method of claim 1 comprising locating the portion of the catheter magnetized to the first polarity at a bulbar portion of the urethra.

4 . The method of claim 1 comprising inflating a balloon of the catheter and locating the portion of the catheter magnetized to the first polarity at a bulbar portion of the urethra.

5 . The method of claim 1 comprising moving a scissors portion of the tool and opening a pathway in the tissue posterior of the urethra.

6 . The method of claim 1 comprising dissecting tissue away from an entire circumference around the urethra.

7 . The method of claim 1 comprising inserting the catheter into the urethra with the portion of the catheter magnetized to the first polarity located in an arc around a portion of a circumference of the catheter.

8 . The method of claim 1 comprising inserting the catheter into the urethra with the portion of the catheter magnetized to the first polarity located in an approximate 180 degree arc around a portion of a circumference of the catheter.

9 . The method of claim 1 comprising inserting the catheter into the urethra with the portion of the catheter magnetized to the first polarity located in an approximate 360 degree arc around a portion of a circumference of the catheter.

10 . The method of claim 1 comprising inserting the catheter into the urethra with the portion of the catheter magnetized to the first polarity located along less than half of a length of the catheter.

11 . The method of claim 1 comprising inserting a proximal portion of the catheter into the urethra and retaining a distal portion of the catheter outside of the urethra; and
providing the distal portion of the catheter with a visual indicator indicating an orientation of the portion of the catheter magnetized to the first polarity.

12 . A method of dissecting tissue, the method comprising:
inserting a catheter into a urethra with a portion of the catheter magnetized; providing a tool with at least a portion of the tool magnetized; and pushing the at least the portion of the tool that is magnetized away from the urethra and dissecting tissue posterior of the urethra with the tool.

13 . A method of dissecting tissue, the method comprising:
inserting a magnetized catheter into a urethra; magnetically pushing a tool away from the urethra with the magnetized catheter; and dissecting tissue posterior of the urethra with the tool.
