    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 edges. 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 edges are configured to cooperate to shear tissue therebetween. The first rotatable member is configured to engage tissue from the target tissue site, rotate towards the second tissue shearing edge. A first axis of the first rotatable member is offset from the longitudinal axis of the elongate member, lies in a common plane and forms an angle therewith of between 0 and 90 degrees. Methods are also disclosed.

    摘要： Catheter control systems which facilitate the tracking of an angle of deflection of a catheter distal end can be used for any number of procedures where catheter orientation relative to the body is desirable, e.g., in transseptal access procedures where an accurate angle of puncture of the septal wall is desirable. Such control systems may comprise a steerable handle which is oriented relative to the catheter steerable section to provide for consistent catheter articulation upon corresponding manipulation of the steering ring. Another variation may utilize an orientation indicator to track the deflectable distal end. For instance, an orientation marker as visualized through an imaging hood on the distal end may correspond to identical orientation markers on the control handle such that articulation of a steering mechanism in a direction relative to the orientation markers deflects the catheter distal end in a corresponding direction relative to the visualized orientation markers.
