Patent number: 8945151Abstract: Apparatus and methods for delivering a surgical clip to a patient during a minimally invasive surgical procedure are disclosed herein. An exemplary apparatus for isolating an atrial appendage of a patient includes a surgical clip that locks onto the atrial appendage of the patient, and a surgical clip applicator that releasably engages the surgical clip. The surgical clip can include a top portion and a bottom portion. The surgical clip applicator can include a first flexible flap and a second flexible flap. The first and second flexible flaps can be sufficiently rigid to prevent the surgical clip from falling off of the surgical clip applicator when the surgical clip is engaged to the surgical applicator and the surgical clip applicator is in a relaxed state, and sufficiently flexible to facilitate separation of the surgical clip from the surgical clip applicator when the surgical clip is locked onto the atrial appendage.Type: GrantFiled: July 13, 2005Date of Patent: February 3, 2015Assignee: AtriCure, Inc.Inventor: Allan Salas

Patent number: 8940014Abstract: An elongated member and a method of manufacturing an elongated member may include first, second, and third elongated rod mandrels. The first, second, and third elongated rod mandrels may be fixed together at predetermined proximal and distal locations and at a ball tip. The first, second, and third rod mandrels may be disposed within a tubular coupling element and fixed to the tubular coupling element at the ball tip. The tubular coupling element may be placed into abutment with and fixed to the distal end of an elongated shaft.Type: GrantFiled: November 14, 2012Date of Patent: January 27, 2015Assignee: Boston Scientific Scimed, Inc.Inventors: Randy S. Gamarra, David S. Tung, Benjamin Sutton, Takashi Ino, Joshua Wallin, Brian D. Brandt

Patent number: 8936614Abstract: A surgical instrument includes a housing supporting first and second actuators thereon, and an elongated shaft extending distally from the housing. First and second drive members extend through the elongated shaft to operatively couple respective actuators to respective jaw members such that independent manipulation of one of the actuators may induce pivotal movement of an individual jaw member. A locking member is operatively associated with the first and second drive members, and is selectively movable between locked and unlocked positions. When the locking member is in the locked position, the first and second drive members are coupled to one another and move concurrently to drive the jaw members in a bilateral manner. When the locking member is in the unlocked position, the drive members are decoupled from one another and move independently to permit operation of the instrument in a unilateral manner.Type: GrantFiled: December 30, 2010Date of Patent: January 20, 2015Assignee: Covidien LPInventor: James D. Allen, IV

Patent number: 8936615Abstract: A bone fixation system includes a bone plate, bone anchors, temporary fixation members, and forceps. The temporary fixation members are configured to be inserted through apertures in the bone plate and into underlying bone segments that are separated by a bone gap. The forceps are configured to apply a force to the temporary fixation members that causes at least one of the underlying bone segments to translate with respect to the other bone segment, thereby reducing or distracting the bone segments without interfering with final fixation by screws of bone segments.Type: GrantFiled: April 27, 2011Date of Patent: January 20, 2015Assignee: DePuy Synthes Products, LLCInventors: Dana Pappalardo, Sherri Wykosky, Kenneth Kobayashi, Dipan Patel, William Kolb, Colleen Flesher

Publication number: 20150018827Abstract: A forceps is provided. The forceps includes a housing having a shaft that extends therefrom. The bipolar forceps also includes a hydraulic mechanism that includes a fluid line and a plunger operatively coupled to the fluid line. The plunger is translatable within at least a portion of the shaft from a proximal position to a distal position. An end effector assembly is operatively connected to a distal end of the shaft and includes a pair of first and second jaw members biased in an open configuration. Each of the first and second jaw members configured to receive at least a portion of the plunger when a fluid is caused to flow within the fluid line such that the first and second jaw members move from an open position for positioning to a closed position for grasping tissue.Type: ApplicationFiled: October 1, 2014Publication date: January 15, 2015Inventor: WILLIAM H. NAU, JR.

Patent number: 8920461Abstract: A forceps includes an end effector assembly having first and second jaw members. Each jaw member includes a bifurcated proximal flange extending therefrom defining first and second spaced-apart flange components. The first flange components are pivotably engaged to one another via a first engagement portion and the second flange components are pivotably engaged to one another via a second engagement portion. One or both of the jaw members is pivotable relative to the other about the first and second engagement portions between an open position and a closed position for grasping tissue therebetween. A guide member is configured for positioning between the proximal flanges of the jaw members. The guide member includes a tab extending transversely therefrom that is configured to operably engaged one of the first and second engagement portions to retain the jaw members in engagement with one another.Type: GrantFiled: May 1, 2012Date of Patent: December 30, 2014Assignee: Covidien LPInventors: Jeffrey R. Unger, James D. Allen, IV, Daniel A. Joseph

Patent number: 8920436Abstract: An endoscopic tissue anchor deployment device includes a handle, an elongated shaft defining an internal lumen, and an end effector attached to the distal end of the elongated shaft. A tissue anchor catheter is removably inserted through the lumen of the elongated shaft, the catheter having a tissue anchor assembly that is deployable from its distal end. The handle may include a pin and track assembly that define a series of handle actuation steps corresponding to deployment steps for the deployment device end effector and the tissue anchor catheter. In some embodiments, the handle includes a catheter stop member that prevents movement of the tissue anchor catheter under certain circumstances, and a handle stop member that prevents actuation of the handle under certain circumstances.Type: GrantFiled: January 11, 2012Date of Patent: December 30, 2014Assignee: USGI Medical, Inc.Inventors: Cang Lam, Richard C. Ewers, Christopher James Earley

Patent number: 8920433Abstract: A manipulator includes a control unit (1), with handle (4) and control buttons (4a-4d), and a connecting arm (2) which, at its proximal end (2a), carries the control unit (1) and, at its distal end (2b), carries a work unit (3). The control buttons (4a-4d) control at least a first inclination motor, which causes a movement of inclination of a tool support (5) of the work unit (3) about a transverse inclination axis (11), and they control the actual rotation of the tool support (5) about its direction of inclination (II) and control the orientation of the direction of inclination (II) about the longitudinal axis (I-I) of the connecting arm (2). A particularly ergonomic manipulator is thus obtained which is easy to learn to use and which efficiently separates the stresses arising from movements of the tool support (5) and the stresses arising from holding and moving the manipulator itself.Type: GrantFiled: July 30, 2010Date of Patent: December 30, 2014Assignee: Dexterite SurgicalInventors: Pascal Barrier, Jérémy Ollagnier, Rémi Rosset-Lanchet, Christine Melennec épouse Barthod, Max Giordano
