Publication number: 20120059453Abstract: Endoprosthesis including a plurality of annular elements, each annular element connected to an adjacent annular element at least one connection location, is provided. Each annular element includes an interconnected series of strut members, at least one strut member connected to a first circumferentially adjacent strut member at a first longitudinal apex and to a second circumferentially adjacent strut member at a second longitudinal apex. The at least one strut member includes a first end portion at a first end of the strut member, the first end extending to the first apex, an intermediate portion hingedly connected to the first end portion, and a second end portion hingedly connected to the intermediate portion and extending to the second apex. The endoprosthesis has a delivery diameter when in a delivery condition and a deployed diameter when in a deployed condition.Type: ApplicationFiled: November 14, 2011Publication date: March 8, 2012Inventors: Jeff Pappas, Anton G. Clifford, Brett Cryer

Patent number: 8109991Abstract: Endoprosthesis, such as a stent, includes at least one annular element defined by a first set of strut members interconnected to define apices proximate opposite sides of the annular element. The annular element further includes a foot extension extending between at least one pair of circumferentially-adjacent strut members. The foot extension has first and second foot portions extending circumferentially from corresponding ends of the circumferentially-adjacent strut members, and are contoured to provide at least two areas of flexure. The first and second foot portions are joined at a toe portion of the foot extension, and define a circumferentially-directed apex between the pair of circumferentially-adjacent strut members. Preferably, at least one or more additional annular elements, each defined by interconnected strut members, are provided. The annular elements are generally expandable between a delivery configuration and a deployed configuration.Type: GrantFiled: October 16, 2009Date of Patent: February 7, 2012Assignee: Abbot LaboratoriesInventors: Anton Clifford, Jeff Pappas, Erik Eli

Publication number: 20100063581Abstract: An endoprosthesis that has a plurality of annular elements, each connected to an adjacent annular element at least one connection location. Each annular element includes an interconnected series of struts, selected strut members of which are each connected to adjacent strut members at a longitudinal apex. The selected strut members extend to a strut end portion at a location on the longitudinally opposite site of the annular element from the apex. At least one of the strut members includes a first end portion at a first end of the strut member, which is located at the strut end portion, an intermediate portion hingedly connected to the first end portion, and a second end portion hingedly connected to the intermediate portion and extending to the apex. The endoprosthesis has a delivery diameter when in a delivery condition and a deployed diameter when in a deployed condition.Type: ApplicationFiled: November 13, 2009Publication date: March 11, 2010Inventors: Jeff Pappas, Anton G.

Patent number: 7637935Abstract: An endoprosthesis that has an interconnected series of struts, selected strut members connected to adjacent strut members at a longitudinal apex. Strut members include a first end portion, an intermediate portion hingedly connected to the first end portion, and a second end portion hingedly connected to the intermediate portion and extending to the apex. Some of the strut members can have a nesting feature configured for nestingly receiving another strut member when the endoprosthesis is in the delivery condition. A scaffolding body of the endoprosthesis can have an inner and outer component, each having a set of interconnected strut members which overlap those of the other to define a cooperating cell pattern. Also, the endoprosthesis can be configured to naturally tend to contract when the body is smaller than a predetermined diameter and expand when the body is larger than a predetermined diameter.Type: GrantFiled: May 6, 2003Date of Patent: December 29, 2009Assignee: Abbott LaboratoriesInventors: Jeff Pappas, Anton G.
