Publication number: 20130041214Abstract: Methods and apparatus for off-axis visualization are described herein. An endoluminal tissue manipulation assembly is disclosed which provides for a stable endoluminal platform and which also provides for effective triangulation of tools. Such an apparatus may comprise an optionally shape-lockable elongate body defining a longitudinal axis and adapted for endoluminal advancement in a patient body, at least one articulatable visualization lumen disposed near or at a distal region of the elongate body, the at least one articulating visualization lumen being adapted to articulate off-axis relative to a longitudinal axis of the elongate body, and at least one articulatable tool arm member disposed near or at the distal region of the elongate body, the at least one articulatable tool arm member being adapted to articulate off-axis and manipulate a tissue region of interest.Type: ApplicationFiled: August 28, 2012Publication date: February 14, 2013Applicant: USGI MEDICAL, INC.Inventors: Tracy D. Maahs, Richard C. Ewers, Arvin T. Chang, Chris Rothe, Eugene C. Chen, Marvin C. Elmer, Gilbert Madrid, Kabir Gambhir

Patent number: 8147535Abstract: Disclosed is a deployment catheter for deploying a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The deployment catheter includes a proximal tubular section and a distal tubular section which are axially movable in opposite directions to deploy a prosthesis. A central core extends throughout the proximal tubular section and into the distal tubular section. A reinforcing structure is carried by the central core, spanning the junction between the proximal tubular section and distal tubular section, to improve flexibility characteristics of the catheter. In one embodiment, the proximal tubular section and/or distal tubular section are rotationally linked to the central core.Type: GrantFiled: July 25, 2005Date of Patent: April 3, 2012Assignee: Endologix, Inc.Inventors: Samuel M. Shaolian, Gilbert Madrid, Thanh Van Nguyen, Trinh Van Pham

Patent number: 8034100Abstract: A graft deployment system, comprises an elongate, flexible catheter body, having a proximal end and a distal end and comprising an outer sheath and an inner core that is axially moveable with respect to the outer sheath. A main vessel graft restraint comprising a first peelable cover for restrains a main vessel portion of a graft. In a bifurcated graft, a first branch vessel graft restraint restrains a first branch vessel portion of the graft. A second branch vessel graft restraint restrains a second branch vessel portion of the graft. The first peelable cover is coupled to a main branch release element and wherein each of the main vessel graft restraint, first branch vessel graft restraint, and the second branch vessel graft restraint are positioned within the catheter body in a graft loaded condition.Type: GrantFiled: November 25, 2003Date of Patent: October 11, 2011Assignee: Endologix, Inc.Inventors: Samuel M. Shaolian, Gilbert Madrid, To Van Pham, Trinh Van Pham
