摘要：
A medical device for removing tissue from a subject is provided with a distal housing, an elongate member, a first rotatable member and first and second tissue shearing surfaces. The distal housing is configured with at least one tissue engaging opening. The elongate member is coupled to the distal housing and configured to introduce the distal housing to a target tissue site. The first rotatable member is located at least partially within the distal housing. The first and second tissue shearing surfaces are located and configured to cooperate with first and second sides of a first blade to shear tissue therebetween. The first rotatable member is configured to engage tissue from the target tissue site, rotate towards the first and second tissue shearing surfaces and inwardly to direct tissue from the target tissue site through the tissue engaging opening and into an interior portion of the distal housing.
