Publication number: 20200121280Abstract: A catheter assembly for an ultrasound system can include an integrated pullback arrangement. For example, the catheter assembly can include a telescoping pullback section having a first telescope, a second telescope, a distal grip coupling one of the first or second telescope to the distal sheath of the distal section, and a proximal grip coupled to another of the first or second telescope so that the first telescope can be retracted into the second telescope and a sensor to determine a position of the first telescope. Another example includes the sensor and a pullback slider arrangement having a housing defining a slit, a coupler disposed within the housing, and a slider handle extending through the slit and coupled to the coupler. In another example, the coupler and housing can be gripped and slid relative to each other.Type: ApplicationFiled: December 17, 2019Publication date: April 23, 2020Inventors: John D. Marshall, Peter Thornton, JR., Lewis J. Thomas, III, Isaac J. Zacharias, Gaylin Mildred Yee

Patent number: 9713523Abstract: The invention provides a stent-graft system comprising a graft member and a stent having a connection end interconnected with the graft member and a free end opposed thereto. A belt retaining structure is provided at the stent free end. A belt is releasably retained in the belt retaining structure and is configured to constrain the stent free end independent of the stent connection end. A method of securing at least one end of a stent-graft within a vessel is also provided.Type: GrantFiled: August 5, 2014Date of Patent: July 25, 2017Assignee: TRIVASCULAR, INC.Inventors: Isaac J. Zacharias, Diego Aristizabal, Michael Mohn, Michael V. Chobotov

Patent number: 8328861Abstract: A delivery system and method for delivering a bifurcated intracorporeal device. The delivery system comprises a shaft having a distal section supporting a primary support member positioned to be disposed within at least a primary portion of the bifurcated intracorporeal device and a secondary support member extending within a secondary portion of the bifurcated intracorporeal device. At least one belt is configured to be circumferentially disposed about a portion of the secondary support member so to at least partially constrain the secondary portion of the bifurcated intracorporeal device. A tube defining a lumen is secured relative to the secondary support member. A release member is configured to engage and releasably secure the belt in a constraining configuration. The release member extends through at least a portion of the tube lumen such that the release member is accessible adjacent a proximal end of the tube.Type: GrantFiled: November 16, 2007Date of Patent: December 11, 2012Assignee: Trivascular, Inc.Inventors: Gerald Ray Martin, James R. Watson, Isaac J. Zacharias

Publication number: 20090082841Abstract: A stent system comprising a stent body. At least one barb extends from the stent body and is configured such that a free end thereof is biased to extend radially outward from the stent body. A retaining mechanism is positioned to engage the at least one barb when the stent body is in a compressed state and retain the at least one barb in a tucked position relative to the stent body.Type: ApplicationFiled: September 26, 2007Publication date: March 26, 2009Applicant: BOSTON SCIENTIFIC CORPORATIONInventors: Isaac J. Zacharias, Maurice Marthaler

Patent number: 7147660Abstract: This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs.Type: GrantFiled: December 20, 2002Date of Patent: December 12, 2006Assignee: Boston Scientific Santa Rosa Corp.Inventors: Michael V. Chobotov, Brian A. Glynn, Stuart E. Kari, John M. Marthaler, Robert G. Whirley, Isaac J. Zacharias, W. Patrick Stephens
