Publication number: 20190076144Abstract: A staple reload includes a body having spaced side walls, an upper surface that extends between the upper ends of the spaced side walls, and tissue stops that extend upwardly from the side walls to a position above the upper surface of the body. A portion of the upper surface of the body positioned distally of the tissue stops defines a tissue contact surface of the body. The tissue contact surface defines rows of staple receiving slots. The tissue stops are positioned adjacent a proximal-most staple receiving slot(s) and have a distal surface that defines the proximal end of the tissue contact surface.Type: ApplicationFiled: August 21, 2018Publication date: March 14, 2019Inventors: Sachin P.

Patent number: 9016545Abstract: An end effector includes a first jaw member, a second jaw member, a drive beam, and a drive screw. The second jaw member is pivotally movable relative to the first jaw member between an open position and a closed position. The drive beam is positioned to engage the second jaw member and is longitudinally movable through the first and second jaw members. The drive screw is supported within the first jaw member and includes a threaded portion coupled to the drive beam such that rotation of the drive screw imparts longitudinal movement of the drive beam along the second jaw member to move the first and second jaw members from the open position to the closed position.Type: GrantFiled: August 21, 2014Date of Patent: April 28, 2015Assignee: Covidien LPInventors: Ernest Aranyi, Dwight Bronson, David Racenet

Patent number: 8899462Abstract: An electromechanical surgical system comprises a hand-held surgical instrument including an instrument housing defining a connecting portion for selectively connecting with a shaft assembly, the surgical instrument having at least one rotatable drive member, and an end effector configured to perform at least one function. The shaft assembly selectively interconnects the end effector and the surgical device. The shaft assembly includes a transmission housing and a force transmitting assembly for interconnecting the rotatable drive member and a rotation receiving member supported in the end effector.Type: GrantFiled: October 25, 2011Date of Patent: December 2, 2014Assignee: Covidien LPInventors: Stanislaw Kostrzewski, Paul A. Scirica, Ernest Aranyi, David Racenet, Frank Marini, Dwight Bronson, William Powers

Patent number: 8851355Abstract: A surgical system has a jaw assembly including a plurality of fasteners, an anvil and a drive beam for pushing an actuation sled. A drive screw imparts motion to the drive beam. An elongated body is configured to connect with the jaw assembly. A drive link connects a flexible drive shaft to the drive screw, the drive link being disposed off-axis. The jaw assembly and elongated body are separable from each other.Type: GrantFiled: January 31, 2014Date of Patent: October 7, 2014Assignee: Covidien LPInventors: Ernest Aranyi, Dwight Bronson, David Racenet

Publication number: 20130098970Abstract: The present disclosure is directed to an endoscopic surgical instrument and methods for performing a diverticulum treatment. The surgical instrument includes a handle assembly, an elongated member and a jaw assembly. The elongated member is operably coupled to the distal end of the handle assembly, while the jaw assembly is operably coupled to a distal end of the elongated member. The jaw assembly includes a knife slot that is defined therewithin and is adapted to receive a knife blade to thereby cut tissue that is disposed between the jaw assembly. The jaw assembly is configured to approximate an esophageal tract and a diverticulum.Type: ApplicationFiled: October 25, 2011Publication date: April 25, 2013Inventors: David Racenet, Dwight Bronson, Ernest Aranyi

Patent number: 8398687Abstract: Disclosed embodiments describe a volar plate generally for use treating distal volar fractures. The volar plate is designed in accordance with anatomical features and is generally Y-shaped, having a wider distal head portion that tapers to a narrower proximal body portion. A plurality of holes in the distal head of the volar plate allow for fixation means to fix the position of bone fragments with respect to the volar plate. The plurality of holes in the distal head basically form two substantially non-linear rows, with the distal row generally curving inward proximally and the proximal row generally curving outward distally such that the fixation means inserted through the holes generally converge. A central cavity may be located in the proximal body of the volar plate to promote bone growth, and mounting screws may border the central cavity on either side to provide secure support. Additionally, K-wire holes may be included which are visually linked to corresponding holes in the distal head.Type: GrantFiled: December 6, 2006Date of Patent: March 19, 2013Assignee: AMEI Technologies, Inc.Inventors: Paul J. Vasta, Michael G. Thomas, David Ruch, David Nelson, Dwight Bronson
