Patent number: 10492822Abstract: Various embodiments of a tissue cutting device are described, such as a device with an elongate tube having a proximal end and a distal end and a central axis extending from the proximal end to the distal end; a first annular element at the distal end of the elongate tube, the first annular element having a flat portion at its distal end perpendicular to the central axis; and a second annular element at the distal end of the elongate tube and concentric with the first annular element, the second annular element having a flat portion at its distal end perpendicular to the central axis, at least one of the first or second annular elements rotatable about the central axis, the rotation causing the first annular element and the second annular element to pass each other to shear tissue.Type: GrantFiled: February 14, 2014Date of Patent: December 3, 2019Assignee: Microfabrica Inc.Inventors: Richard T. Chen, Ming-Ting Wu, Arun Veeramani, Vacit Arat, Gregory P. Schmitz

Publication number: 20170014148Abstract: Medical devices for shearing tissue into small pieces are provided. One exemplary device includes oppositely rotating first and second rotatable members, each located at least partially within a distal housing. The device also includes first and second circular axle portions, and first and second blades that are directly adjacent to one another and positioned to partially overlap such that tissue may be sheared between the first and second blades, between the first blade and the second axle portion and between the second blade and the first axle portion. The rotatable members are configured to engage tissue from a target tissue site with teeth of the first and second blades, rotate towards one another and inwardly to direct tissue from the target tissue site through a tissue engaging opening and into an interior portion of the distal housing. Methods of fabricating and using the above device are also disclosed.Type: ApplicationFiled: September 27, 2016Publication date: January 19, 2017Inventors: Gregory P. SCHMITZ, Ming-Ting WU, Richard T. CHEN, Arun VEERAMANI

Publication number: 20160135831Abstract: 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.Type: ApplicationFiled: January 25, 2016Publication date: May 19, 2016Inventors: Gregory P. SCHMITZ, Juan Diego PEREA, Ming-Ting WU, Richard T. CHEN, Arun VEERAMANI

Publication number: 20140114336Abstract: 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.Type: ApplicationFiled: October 24, 2012Publication date: April 24, 2014Inventors: Gregory P.
