Patent number: 8343211Abstract: A stent assembly comprises a second stent body and a substantially tubular first stent body defining a first lumen and containing a side branch opening. In an undeployed state, the second stent body is at least partially comprised of rings having peaks and valleys at least some of the valleys of adjacent rings being interconnected by bridges. In an expanded state, the rings of the second stent body define a second lumen opening in fluid communication with the first lumen. The second lumen has superior body vessel coverage and is flexible enough to form an oblique angle relative to the longitudinal axis of the first stent body.Type: GrantFiled: December 14, 2005Date of Patent: January 1, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: Daniel Gregorich, Michael P.

Patent number: 8038706Abstract: A stent assembly comprises a proximal stent and a distal stent. Each stent has a tubular body defining a stent lumen and a circumference. A proximal flap extends from the distal end of the proximal stent and a distal flap extends from the proximal end of the distal stent. Each flap defines only a portion of the circumference. In an expanded state the proximal flap and the distal flap form a side branch support having a side branch support lumen. The side branch support lumen is in fluid communication with the stent lumen and has a longitudinal axis different from that of the stent lumen.Type: GrantFiled: September 8, 2005Date of Patent: October 18, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Tracee Eidenschink, Matt Heidner, Michael P.

Patent number: 8016878Abstract: A stent may comprise a plurality of serpentine bands connected by connector struts. The stent may further comprise a side branch cell having a plurality of outwardly deployable petals. Each serpentine band may have an approximate longitudinal axis. A portion of the serpentine bands may be flared in the unexpanded state, wherein a portion of the axis of each flared band is oriented helically about a portion of the stent. The bands may reorient during stent expansion, whereafter the axis of each band is oriented in a circumferential direction.Type: GrantFiled: June 1, 2009Date of Patent: September 13, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Michael P. Meyer, Daniel Gregorich, Shawn Sorenson, Richard C. Tooley

Patent number: 7938855Abstract: An endoprosthesis includes a brittle layer, e.g. a ceramic and an underlayer to accommodate dimensional changes as the endoprosthesis is flexed.Type: GrantFiled: November 2, 2007Date of Patent: May 10, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Daniel J. Gregorich, Shawn Sorenson

Patent number: 7922758Abstract: A bifurcated stent that uses turning segments to reduce the strain at regions which bend at extreme angles. The turning segments can be placed on side branch petals or on connectors connecting the petals to the stent body. Combining the turning segments with connectors of different length and tethers provides for a stent with high flexibility that can accommodate various shaped body vessels. This design allows the bifurcation branch to extend easily, to a useful distance, and to be deployed along oblique angles. Best of all, this design avoids the problems of angularly strained side branch.Type: GrantFiled: June 20, 2007Date of Patent: April 12, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Daniel Gregorich, Kevin Grotheim, Michael P. Meyer, Shawn Sorenson, Samuel Robaina
