Patent number: 11160677Abstract: A method is used to reduce a volume of a stomach of a patient. The method includes inverting a portion of a stomach wall to thereby create an inverted portion. An expandable member is positioned adjacent to the outer surface of the inverted portion. The expandable member is expanded to thereby expand the inverted portion. The expanded expandable member has a first outer diameter. A base region of the inverted portion is cinched to thereby capture the expanded expandable member in the expanded inverted portion. The expanded expandable member has a first outer diameter. Expanding and cinching provide a cinch diameter to first outer diameter ratio from approximately 0.5:1 to approximately 0.9:1.Type: GrantFiled: September 5, 2018Date of Patent: November 2, 2021Assignee: Ethicon, Inc.Inventors: Bethany F.

Patent number: 7037305Abstract: A medical instrument for positioning an internal organ during surgical and diagnostic procedures is provided. In one embodiment, the medical instrument includes a body having a tissue grasping element and an actuating member effective to move the tissue grasping element between an open position and a closed position. The body also includes a flexible member which has a portion secured to the body and at least one free end. In use, the tissue grasping element grasps or penetrates a portion of the tissue on or near the body organ. Tension can then be applied to the flexible member to reposition and secure the body organ.Type: GrantFiled: April 30, 2001Date of Patent: May 2, 2006Assignee: Ethicon, Inc.Inventors: Ronald J. Kolata, Michael F. Clem, Christopher J. Hess, Gary W. Knight, Kristin L. Jambor, David L. Hamann

Publication number: 20040162505Abstract: An automated fine needle biopsy device is described for extracting tissue from the body predominantly in suspected cases of breast cancer. However, it can be used in other parts of the body accessible to needle biopsy. The device causes a fine needle, which is attached to the device, to reciprocate and/or rotate at the same time causing tissue to enter the needle. The depth and number of the thrusts can be pre-programmed, and the force behind each thrust is constant. Suction may or may not be used. The tissue extracted is subsequently expelled onto glass slides for microscopic interpretation. This device and method offer a vast improvement over the present method for fine needle biopsy wherein it is performed manually and in a very haphazard way. The prime deficiency of the manual method currently used is insufficient tissue extraction. This device will correct that situation enabling accurate diagnosis to be made on adequate tissue samples obtained.Type: ApplicationFiled: February 10, 2004Publication date: August 19, 2004Inventors: Leopold S. Kaplan, Lawrence J. Kelly, David L. Hamann

Patent number: 6193652Abstract: In accordance with the present invention there is provided a device for stabilizing and/or manipulating moving tissue, such as a beating heart, so as to facilitate surgical procedures on such tissues. The device includes a tube having a proximal end, a distal end and a lumen extending therebetween. The tube is operatively connected to a suction source so as to draw air through the tube from the distal end to the proximal end. The device further includes at least one foot operatively connected to the distal end of the tube. The foot extends laterally from the tube. In a preferred embodiment the device includes a pair of feet which are spaced apart laterally from each other. Each foot has a proximal surface, and a distal surface for making contact with the tissue. The distal surface of each foot has an outer perimeter having a substantially spherical profile. This spherical profile helps the device make better contact with the tissue, so the tissue can be more effectively manipulated.Type: GrantFiled: October 7, 1997Date of Patent: February 27, 2001Assignee: Ethicon Endo-Surgery, Inc.Inventors: Craig B.

Patent number: 6187019Abstract: In accordance with the present invention, there is provided a surgical device for attaching a first hollow organ to a second hollow organ and creating a passageway therebetween. The device includes a first member comprising a first prong for entering a wall of the first hollow organ and a second prong for entering a wall of the second hollow organ. The prongs each have a proximal end which attaches to the first member and a distal end extending therefrom. The device further includes a second member having a plow for incising at least one of the hollow organs so as to create a passageway between the hollow organs. The second member further includes a plurality of needle paths on either side of the plow for guiding a needle through the walls of the hollow organ on either side of the passageway. The device further includes a means for driving a needle, having a suture attached thereto, so as to attach the hollow organs together.Type: GrantFiled: October 5, 1999Date of Patent: February 13, 2001Assignee: Ethicon Endo-Surgery, Inc.Inventors: David Stefanchik, David L.
