Patent number: 9078695Abstract: Methods and devices are provided for providing access through tissue to a surgical site. In one embodiment, a surgical access device can include a hollow tubular member and a modular seal member. The modular seal member can be configured to radially span a lumen of the tubular member and can be removably and replaceably matable to a portion of the tubular member. The access device can also include a plurality of access ports, each of which can be configured to mate with the modular seal member at a respective desired location.Type: GrantFiled: June 5, 2009Date of Patent: July 14, 2015Assignee: Ethicon Endo-Surgery, Inc.Inventors: Christopher J.

Patent number: 8419766Abstract: The present invention provides a flexible actuator, and methods for manufacturing and using a flexible actuator, for transmitting high loads from a user to an end effector. In one exemplary embodiment, the flexible actuator can extend from a handle of a medical device to an end effector located on a distal end of the device. The actuator can include a head formed on a terminal end thereof with at least one planar surface that is approximately coplanar with an outer surface of the flexible actuator. In use, the actuator can be coupled to a medical device having an end effector located on a distal end thereof. Tension applied to the actuator can be effective to actuate the end effector.Type: GrantFiled: December 15, 2009Date of Patent: April 16, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: Dean Bruewer, Jose L. Francese, Carlos M. Rivera, Jeffrey David Messerly

Patent number: 8216255Abstract: A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.Type: GrantFiled: June 14, 2004Date of Patent: July 10, 2012Assignee: Ethicon Endo-Surgery, Inc.Inventors: Kevin W. Smith, Jeffrey David Messerly, Barry Thomas Jamison, Peter K. Kratsch, Carlos Rivera, Jose Luis Francese, Kristin Nicole Werner Dawson, Chester O. Baxter, III, Juergen A. Kortenbach

Patent number: 8179074Abstract: Methods and devices are provided for rotating an end effector on a long, flexible medical device. The methods and devices utilize an actuator mechanism that is effective to rotate an end effector on the distal end of an elongate flexible shaft. The actuator mechanism is movable between a freely rotatable position and a rotationally resistant position. When the actuator mechanism is in a freely rotatable position, the actuator mechanism can be rotated to impart torque to the end effector, and thus at least a distal portion of the elongate shaft, to cause the end effector to rotate. In order to prevent the actuator mechanism from “freewheeling,” wherein the actuator mechanism freely rotates in an opposite direction upon release rather than the end effector rotating in the desired direction, the actuator mechanism can be moved to the rotationally resistant position.Type: GrantFiled: October 19, 2009Date of Patent: May 15, 2012Assignee: Ethicon Endo-Surgery, Inc.Inventors: Jeffrey David Messerly, Gary W. Knight, Barry Thomas Jamison, William Douglas Shaw, Jr.

Patent number: 7815652Abstract: A surgical fastener including a filament formed into a generally helical shape around a fastener axis and having a plurality of coils. The proximal end of the filament has an engagement member and the distal end of the filament has a penetrating tip. The engagement member may be driven to rotate the penetrating tip about the fastener axis such that the coils screw into tissue held in the path of the penetrating tip.Type: GrantFiled: March 21, 2006Date of Patent: October 19, 2010Assignee: Ethicon Endo-Surgery, Inc.Inventors: Jeffrey David Messerly, Chester O.

Patent number: 6923806Abstract: A method and apparatus for transmural ablation using an instrument containing two electrodes or cryogenic probes. A clamping force is exerted on the two electrodes or probes such that the tissue of the hollow organ is clamped therebetween. Bipolar RF energy is then applied between the two electrodes, or the probes are cryogenically cooled, thus ablating the tissue therebetween. A monitoring device measures a suitable parameter, such as impedance or temperature, and indicates when the tissue between the electrodes has been fully ablated.Type: GrantFiled: December 12, 2001Date of Patent: August 2, 2005Assignee: Atricure Inc.Inventors: Michael D.

Publication number: 20020165577Abstract: An ultrasonic surgical instrument which incorporates a thumb and finger ring-actuated structure for the ultrasonic clamping device which is finger-operated in a scissor-like mode. Provided is either a fixed or removable blade tip and clamp assembly for ultrasonic treatments, so as to impart to the surgical instrument the ability of providing a variety of essentially exchangeable tips while reducing operationally engendered vibrations and stresses at the point of the coupling thereof to the clamp arm. The assembly is actuatable by relative movements between a blade extender and an outer tubular sheath extending to a handle end connected to the thumb and finger ring-actuated structure.Type: ApplicationFiled: May 4, 2001Publication date: November 7, 2002Applicant: Ethicon Endo-Surgery, Inc.Inventors: David Alan Witt, Craig N.
