Patent number: 9545299Abstract: A prosthesis delivery and deployment device includes an elongate and flexible outer catheter. The outer catheter has a tubular wall of layered construction, including translucent layers, opaque layers, and a braid composed of helically wound metal filaments. The outer catheter has a translucent distal adapted to constrain a radially self-expanding prosthesis in a radially reduced, axially elongated state. Because the stent constraining region is translucent, an endoscope can be used to visually monitor the stent when so constrained. Radiopaque markers can be mounted to the outer catheter and to an inner catheter used to deploy the prosthesis, to afford a combined visual and fluoroscopic monitoring for enhanced accuracy in positioning the prosthesis, both before and during its deployment.Type: GrantFiled: September 16, 2013Date of Patent: January 17, 2017Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Jennifer E. Raeder-Devens, Susan I. Shelso, James F. Hemerick, Eric Schneider, Heather Getty, Doreen Borgmann, Kakao Sisombath, Jeffrey A. Helgerson

Publication number: 20120239128Abstract: Techniques are disclosed that allow a stent to be folded within a balloon of a stent delivery system. In one example, a stent has first and second columns that extend from a proximal end to a distal end along a longitudinal axis. Each of the first columns extend substantially parallel to the longitudinal axis and comprise a plurality of elements that each have a substantially polygonal shape. Each of the second columns extend substantially parallel to the longitudinal axis and are between adjacent first columns. Each of the respective second columns include a plurality of first connectors that have a curvilinear shape and that extend in a substantially circumferential direction to connect adjacent first columns. The stent also has a plurality of second connectors, wherein at least one of the second connectors extends between a first element and a second element.Type: ApplicationFiled: September 22, 2011Publication date: September 20, 2012Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Brian Tischler, James F.

Patent number: 8226702Abstract: A prosthesis delivery and deployment device includes an elongate and flexible outer catheter. The outer catheter has a tubular wall of layered construction, including a translucent inner liner running the complete catheter length, and three outer layers including a translucent distal layer, an opaque medial layer and an opaque proximal outer layer. The outer layers are adjacent one another and are bonded to the liner. A braid composed of helically wound metal filaments is disposed between the liner and the proximal and medial outer layers, and includes a distal portion between the liner and a proximal portion of the distal outer layer. The liner and distal outer layer provide a translucent distal region of the catheter that is adapted to constrain a radially self-expanding prosthesis in a radially reduced, axially elongated state. Because the stent constraining region is translucent, an endoscope can be used to visually monitor the stent when so constrained.Type: GrantFiled: May 18, 2009Date of Patent: July 24, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Jennifer E Raeder-Devens, Susan I Shelso, James F Hemerick, Eric M Schneider, Heather L Getty, Doreen M Borgmann, Kakao Sisombath, Jeffrey A Helgerson
