Patent number: 10219904Abstract: Medical devices, systems, and methods reduce the distance between two locations in tissue, often for treatment of congestive heart failure. In one embodiment an anchor of an implant system may reside within the right ventricle in engagement with the ventricular septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along an epicardial surface. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a catheter. An anchor force may be applied within a desired range to secure the anchors about the septum and epicardial surface. The anchor force may inhibit migration of the anchors relative to the septum and epicardial surface.Type: GrantFiled: November 2, 2015Date of Patent: March 5, 2019Assignee: BioVentrix, Inc.Inventors: William Butler, Kevin Van Bladel, Ernie Heflin, Lon Annest, Rovil Arcia, John Bower

Patent number: 9889008Abstract: Medical devices, systems, and methods reduce the distance between two points in tissue, often for treatment of congestive heart failure and often in a minimally invasive manner. An anchor is inserted along an insertion path through a first wall of the heart. An arm of the anchor is deployed and rotationally positioned according to a desired alignment. Application of tension to the anchor may draw the first and second walls of the heart into contact along a desired contour so as to effect a desired change in the geometry of the heart. Additional anchors may be inserted and aligned with the first anchor to close off a portion of a ventricle such that the ventricle is geometrically remodeled and disease progression is reversed, halted, and/or slowed.Type: GrantFiled: November 2, 2016Date of Patent: February 13, 2018Assignee: BioVentrix, Inc.Inventors: Lon S. Annest, Claudio Argento, William Butler, Ernest Heflin

Publication number: 20170348044Abstract: An end effector assembly of a forceps includes a first jaw with a tissue sealing surface and an electrode on the sealing surface, and a second jaw with a tissue sealing surface and an electrode on the sealing surface. The first jaw and the second jaw move between an open position and a closed position. The sealing surface of at least one of the first jaw and the second jaw has a rigid medial section and flexible lateral sections.Type: ApplicationFiled: May 23, 2017Publication date: December 7, 2017Inventors: Huisun Wang, Kester J.

Publication number: 20170196579Abstract: An instrument that includes an outer member, an inner member, and a jaw assembly. The inner member includes a first arm and a second arm. The jaw assembly includes a first jaw and a second jaw. The first jaw is connected to the first arm at a first pivot joint and to the outer member at a second pivot joint. The second jaw is connected to the second arm at a third pivot joint and to the outer member at a fourth pivot joint. The inner member is adapted to be moved distally relative to the outer member so that the first jaw pivots about the second pivot joint towards the second jaw and the second jaw pivots about the fourth pivot joint towards the first jaw thus moving the jaw assembly from the open position towards the closed position.Type: ApplicationFiled: January 10, 2017Publication date: July 13, 2017Inventors: Kester J. Batchelor, Eric J. Boone, Christian J. Fiksen, Hanam Sota Pham, Zane Ward, Jeffrey J. Nelson, John R. Mensch, William Butler, William F. Kratoska, Riyad E. Moe

Patent number: 9593057Abstract: The invention generally relates to a hydrocarbon process for reducing condensation in a vapor-liquid amine or caustic acid gas scrubber. A first mixture is provided, the first mixture being superheated and comprising C2+ mono-olefin, acid gases, and diolefin molecules. The first mixture is divided into a first stream and a second stream, the first and second streams having substantially the same composition. The first stream is cooled to produce a gas phase and a liquid phase, the gas phase comprising less C6+, the liquid phase containing more C6+. The gas phase is separated to create a third stream. The third stream and the second stream are combined to form a second substantially superheated mixture. The second mixture is conducted to an acid gas scrubbing tower. The invention also relates to an apparatus for carrying out this process.Type: GrantFiled: October 17, 2014Date of Patent: March 14, 2017Assignee: ExxonMobil Chemical Patents Inc.Inventors: Thomas W.

Publication number: 20160095600Abstract: Medical devices, systems, and methods reduce the distance between two locations in tissue in a minimally invasive manner, often for treatment of congestive heart failure. In one embodiment, an anchor of an implant system may, when the implant system is fully deployed, reside within the right ventricle in engagement with the ventricular septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along an epicardial surface of the heart. Deployment of the anchor within the right ventricle may be performed by inserting a guidewire through the septal wall into the right ventricle. The anchor may be inserted into the right ventricle over the guidewire and through a lumen of a delivery catheter. Delivering the anchor over the guidewire may provide improved control in the delivery and placement of the anchor within the right ventricle.Type: ApplicationFiled: November 2, 2015Publication date: April 7, 2016Inventors: Lon Annest, Murray Sheldon, Kevin Van Bladel, Ernie Heflin, William Butler, Andrew Wechsler, John Bower, Rovil Arcia

Patent number: 8650009Abstract: A continuous emissions model system is described that employs an emissions model that can determine emissions values from a plant for use in place of sensed emission data in the event of failure or lack of communication from a sensor. The emissions model itself receives inputs that may be based upon sensed data. Each emissions model input may be substituted with a modeled input. The modeled inputs, as well as the emissions model outputs maybe biased to render them more accurate. If any one of the emissions model inputs fails (e.g., becomes unavailable or is clearly erroneous), the corresponding modeled input may be utilized so long as the modeled input passes an acceptability test.Type: GrantFiled: August 31, 2010Date of Patent: February 11, 2014Assignee: Rockwell Automation Technologies, Inc.Inventors: William Butler Forbes, Michael Eugene Sugars, Walter Edgar Hayes, IV, Eugene Boe, Scott Lawrence Jost, Richard Andrew Hovan, Keith Alex Smith
