  • Tissue resectors with cutting wires, hand operated tissue resecting systems and associated methods
    Patent number: 11446050
    Abstract: A tissue resector includes an outer cannula with a cutting element disposed therein. The outer cannula includes an opening that is configured to be associated with a cutting element of the cutting element in such a way that when tissue is drawn into the opening of the cannula, a cutting element of the cutting element can be rotated past the opening to engage and cut into and through the tissue. The outer cannula and the cutting element may also be configured to enable aspiration of the tissue. A tissue resector according to this disclosure may be used with a hand-held, hand-operated rooter.
