Patent number: 8951274Abstract: Disclosed are methods and devices for removing tissue from a site in a hollow organ, where the device has a low crossing profile and is capable of removing tissue at a high rate of speed. The device includes an elongate outer tube with a side opening and an inner tube moveably coaxially positioned within the outer tube. Tissue drawn into the side opening can be severed by moving the inner tube across the opening. Tissue may be removed through the device at a rate of at least about 1.4 cc per minute, through a lumen having a cross-sectional area of no greater than about 12.02 mm. Cutting may be accomplished by rotating the inner tube at a speed of at least about 4000 rpm, and axially reciprocating the inner tube at a rate of at least about 1.5 cycles per second. The window may have a rho value of no more than about 1, and the outside diameter of the device may be no more than about 3 mm.Type: GrantFiled: April 29, 2009Date of Patent: February 10, 2015Assignee: Hologic, Inc.Inventors: Ronald David Adams, Albert Chun-Chi Chin, Roy Hewitt Sullivan, Eric Karl Litscher, William Lucas Churchill, William Harwick Gruber

Patent number: 8574253Abstract: A method and device for tissue removal. The device may be used to remove uterine fibroids and other abnormal gynecological tissue. According to one embodiment, the device includes a housing, an outer tube, and an inner tube. The outer tube is fixed to the housing and includes a side window proximate to its distal end. The side window may have sloped proximal and distal ends. The inner tube has a distal end positioned within the outer tube, the distal end being adapted to rotate and, at the same time, to move back and forth past the side window, with the rotational and translational movement of the inner tube being independently controllable. The distal end of the inner tube may have an external bevel. Suction is applied to the proximal end of the inner tube to draw tissue into the side window and to remove resected tissue through the inner tube.Type: GrantFiled: April 4, 2008Date of Patent: November 5, 2013Assignee: Hologic, Inc.Inventors: William Harwick Gruber, Ronald David Adams, Albert Chun-Chi Chin, Eric Karl Litscher, Roy Hewitt Sullivan, Paul DiCesare, Jeffrey Radziunas, Daniel Vigliotti, Bryan Dale Knodel, Chris Scott Daniels, Kevin J.

Publication number: 20120172889Abstract: A tissue removal system includes an inner tubular member configured to rotate and oscillate axially relative to an outer tubular member, and a reversible motor comprising a rotatable output shaft operatively coupled to the inner tubular member. A proximal end of the inner tubular member is disposed within, and configured to rotate and oscillate axially relative to, a housing. A first control switch disposed within the housing is actuated when the inner tubular member is in a distal position relative to the housing, and a second control switch disposed external to the housing is actuated by a user. The system further includes motor control circuitry configured such that when the second control switch is actuated, actuation of the first control switch causes the motor output shaft to change direction, and when the second control switch is not actuated, actuation of the first control switch causes the motor to turn off.Type: ApplicationFiled: January 5, 2012Publication date: July 5, 2012Applicant: HOLOGIC, INC.Inventors: Albert Chun-Chi Chin, Matthew John Whitney, Roy Hewitt Sullivan

Publication number: 20090270895Abstract: Disclosed is a tissue removal device having an outer tube with a resection window and an inner tube disposed within the outer tube. The inner tube is slidable and rotatable relative to the outer tube so that the distal end of the inner tube moves back and forth across the resection window to sever tissue extending therethrough. The inner tube may be driven to rotate at a speed of at least about 1100 rpm, to axially translate at a rate of at least about 1.5 cps, and with an advance ratio of no more than about 0.25. The drive system for controlling axial reciprocation and rotation of the inner tube may be totally mechanical.Type: ApplicationFiled: April 29, 2009Publication date: October 29, 2009Applicant: Interlace Medical, Inc.Inventors: William Lucas Churchill, Roy Hewitt Sullivan, Albert Chun-Chi Chin, Eric Karl Litscher, William Harwick Gruber, Ronald David Adams

Publication number: 20090270898Abstract: Disclosed is a tissue removal device. The device includes an outer tubular body, an inner tubular body and a cutting edge on the inner tubular body. The outer tubular body includes a window, which may be opened or closed by moving the cutting edge. The cutting edge has a hardness that exceeds the hardness of the material of the inner tube. The cutting edge may have a Rockwell C hardness of at least about 50, while the inner tube has a Rockwell C hardness of no more than about 40. The cutting edge may be formed by a milling step, and the inner tube may be formed by a drawing step. Tissue severed by the cutting edge may be removed at a rate of at least about 1.8 grams per minute through the inner tube, and the outer tubular body may have an outside diameter of no more than about 3.5 mm.Type: ApplicationFiled: April 29, 2009Publication date: October 29, 2009Applicant: Interlace Medical, Inc.Inventors: Albert Chun-Chi Chin, Roy Hewitt Sullivan, Eric Karl Litscher, William Lucas Churchill, Ronald David Adams, William Harwick Gruber, David Jacobs
