Abstract
A stent delivery system is provided that comprises an inner member and an expandable balloon mounted on the inner member. A stent, which is mounted around at least a portion of the expandable balloon, comprises a plurality of alternating, hingedly-coupled crown sections and strut sections. Each adjacent crown section and strut section is coupled together via a hinge comprising a region having a thickness substantially less than that of the adjacent crown section and strut section.
Claims20
A stent delivery system, comprising:
- an inner member;
- an expandable balloon mounted on said inner member;
- and
- a stent mounted around at least a portion of said expandable balloon, said stent comprising a plurality of alternating, hingedly-coupled crown sections and strut sections.
A stent delivery system, comprising:
- a tubing;
- an expandable balloon mounted on said tubing;
- and
- a stent mounted around at least a portion of said expandable balloon, said stent including at least one stent section comprising:
- a plurality of successive crown sections each having first and second leg members;
- a plurality of elongated strut sections each coupled between a first leg of a first one of said plurality of crown sections and a second leg of a second one of said plurality of said crown sections;
- a first plurality of hinge regions each disposed between one of said strut sections and one of said first legs;
- and
- a second plurality of hinge regions each disposed between one of said strut sections and one of said second legs.
An endovascular support device for mounting on a balloon catheter and configured to be expandably deployed in a patient's vasculature, the device comprising a plurality of J-shaped stent section units successively coupled together to form a serpentine-like mesh, each J-shaped section comprising:
- a crown having a first leg member, a second leg member, and a curved portion;
- and
- an elongated strut having a first end coupled to said first leg member and separated therefrom by a first region having a thickness substantially less than that of said first leg member proximate said first end to facilitate bending said strut relative to said crown when the support device is expanded.
A method for producing a stent configured for radial expansion, comprising:
- forming a generally tubular stent body comprising a plurality of alternatively coupled crown sections and strut sections;
- and
- reducing the thickness of the stent body proximate selected crown/strut junctions to facilitate the bending of said strut sections relative to said crown sections.
