Publication number: 20170138150Abstract: Systems and methods are provided for moving a well casing plug to desired locations in a well. The well plug system can be located at a desired position, generate a reversible seal at the location, remove the seal, and relocate. Features of the plug system, such as translocating devices, actuating devices, sensors, and casing penetration tools can allow work to be done at various well hole locations, e.g., without requiring continuous physical connections or communications with the surface. The methods include sealing the well casing plug in a casing, opening ports through the casing, facilitating passage of fluids at hydraulic fracturing pressures to formations outside the casing, reversing the seal, and translocation of the plug system to a new location.Type: ApplicationFiled: November 16, 2015Publication date: May 18, 2017Inventor: Stephen A.

Patent number: 8182494Abstract: A minimally-invasive anastomosis system includes a base that is inserted through an incision is made in the chest of a patient between two adjacent ribs. An anastomosis tool and a sensor are attached to the base. The base is attached to the heart, such as by suction, while allowing substantially unrestricted motion of the heart. The sensor provides a view of a surgical field to a display, such that as the base moves along with the motion of the heart, the view of the surgical field remains substantially steady.Type: GrantFiled: April 21, 2003Date of Patent: May 22, 2012Assignee: Cardica, Inc.Inventors: Stephen A.

Patent number: 8012164Abstract: An auger is axially fixed to and positioned within a cutter. The auger and cutter advance at the same time relative to a contact structure placed against a vessel, penetrating the wall of the vessel and cutting a tissue plug. When the auger and the cutter are retracted from the vessel wall, the tissue plug is retained by the auger and cutter and removed from the vessel wall. The auger and the cutter thus create an opening in the vessel wall, without the need for a prior incision in that wall.Type: GrantFiled: January 22, 2002Date of Patent: September 6, 2011Assignee: Cardica, Inc.Inventors: Brendan M. Donohoe, Theodore M. Bender, Brian R. DuBois, Scott O. Chamness, Stephen A. Yencho, Jaime S. Vargas, Nathan H. White, Gregory B. Arcenio, Heather L. Klaubert, Russell C. Mead, Jr.

Patent number: 7862728Abstract: An Ultraviolet-C (UVC) based portable water purification system employing a novel array of baffles increases the efficiency per unit energy of irradiating UVC light in the eradication of pathogens in the water. Closed loop feedback allows monitoring the application of UVC light power to ensure high levels of pathogen eradication. This system is capable of eradicating a wide range of waterborne bacteria, viruses, protozoa, helminthes, yeast, and mold found in natural freshwater sources worldwide. By adding pre- or post-filters, the system can remove harmful organic compounds, pesticides, inorganic compounds and heavy metals from the water. The system can also be used to eradicate pathogens in fluids other than water. As a feature of this invention, a communications systems that can reach geographically dispersed populations at low cost without the need to install costly wired communications infrastructure is combined with and powered by the water purification system.Type: GrantFiled: September 27, 2007Date of Patent: January 4, 2011Assignee: Water of Life, LLC.Inventor: Stephen A.

Patent number: 7766924Abstract: An anastomosis tool includes a handle connected to a tissue effector that may be capable of being oriented in two or more positions relative to the handle. The tissue effector holds a graft vessel having at least one flap defined in at least one end thereof against the side of a target vessel. Actuation of a trigger or other mechanism on the handle causes the tissue effector to deploy one or more connectors into the flaps of the graft vessel and the side of the target vessel, thereby connecting the graft vessel to the target vessel.Type: GrantFiled: March 19, 2003Date of Patent: August 3, 2010Assignee: Cardica, Inc.Inventors: David L.

Patent number: 7611523Abstract: An anastomosis device is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes an expandable tube configured to have a graft vessel secured to the tube. The device has an expandable linkage positioned at one end of the device and expansion of this linkage causes a first radially extending flange to fold outward. This first flange abuts an interior wall of a target vessel and a second flange is formed which abuts an exterior wall of the target vessel trapping the target vessel between the two flanges and secures the end of the graft vessel into an opening in the wall of the target vessel. The device greatly increases the speed with which anastomosis can be performed over known suturing methods and allows anastomosis to be performed in tight spaces.Type: GrantFiled: September 18, 2003Date of Patent: November 3, 2009Assignee: Cardica, Inc.Inventors: Jaime Vargas, Stephen A.
