  • TISSUE REMOVAL SYSTEM
    Publication number: 20210186472
    Abstract: A tissue removal device includes a housing, an outer tube having a distal portion configured for transcervical insertion into a uterus, an inner tube slidably disposed within the outer tube lumen, a vacuum generation chamber disposed within the housing, a movable piston slidably disposed in the vacuum generation chamber, a collection chamber, a manual actuator moveably coupled to the housing and operatively coupled to the piston, and proximal and distal one-way valves. The outer tube has an outer tube lumen, a tissue in-take opening proximate a distal end thereof, and a proximal end coupled to the housing. The inner tube has an inner tube lumen extending from an open inner tube distal end to an open inner tube proximal end, the open inner tube distal end comprising a cutting edge configured to sever intrauterine tissue extending through the tissue in-take opening in the outer tube.
