ABSTRACT:
The present invention provides a resectoscope and a method for lasing, coagulating, resecting, removing and retrieving prostate tissue. The resectoscope of the invention includes an interstitial laser fiber as a laser directing system and a unique configuration of an extensible and retractable plurality of thin blades which are capable of forming a plurality of elliptical shapes. Laser radiation sources are to be used with the device. This combination provides a more efficient and safer surgical method and provides the additional benefit without impairing the cellular integrity of the tissue. Thus, the retrieved tissue is preserved for histological analysis.
