Apparatus and method for prostatic tissue removal
First Claim
Patent Images
1. A method of removing a tissue of a prostate proximate a urethra having an inner lining, comprising:
- positioning a catheter in the urethra;
inserting a mechanical debrider through the catheter;
positioning the mechanical debrider in the prostate proximate the tissue to be removed;
rotating the mechanical debrider against the tissue;
removing the prostatic tissue, thereby forming a first cavity adjacent the inner lining of the urethra; and
re-positioning the mechanical debrider and forming a second cavity adjacent the urethra, wherein the first cavity and the second cavity are in direct fluid communication such that fluid can flow from the first cavity to the second cavity without entering the urethra.

23. A method of removing a tissue of a prostate proximate a urethra having an inner lining, comprising:
-
positioning a catheter in the urethra; inserting a mechanical debrider through the catheter; positioning the mechanical debrider in the prostate proximate the prostatic tissue to be removed; rotating the mechanical debrider against the prostatic tissue; urging the prostatic tissue into a path of the rotating mechanical debrider by expanding an expandable member in the urethra during rotation of the mechanical debrider; and removing the prostatic tissue, thereby forming a cavity adjacent the inner lining of the urethra. - View Dependent Claims (24, 25, 26, 27)

28. A method of removing a tissue of a prostate proximate a urethra having an inner lining, comprising:
-
positioning a catheter in the urethra;
inserting a mechanical debrider through the catheter;advancing the mechanical debrider through a sidewall of the catheter at an angle to the catheter; positioning the mechanical debrider in the prostate proximate the tissue to be removed; adjusting the angle of the mechanical debrider, within the prostate, to an angle substantially parallel to the urethra; rotating the mechanical debrider against the tissue; removing the prostatic tissue, thereby forming a cavity adjacent the inner lining of the urethra; and re-positioning the mechanical debrider and forming a second cavity adjacent the urethra, wherein the first cavity and the second cavity are in direct fluid communication.
