Abstract
An embodiment of the invention provides a prosthesis for placement at an Os opening from a main body lumen to a branch body lumen. The prosthesis comprises a radially expansible support and a plurality of fronds extending axially from an end of the support. The support is configured to be deployed in at least a portion of the branch body lumen. At least one of the plurality of fronds is extendable into the main body lumen.
Claims20
A method for treating a bifurcation between a main lumen and a branch lumen, comprising the steps of:
- providing a radially expandable scaffold, having a proximal end, a distal end, a support structure on the distal end, and at least two fronds extending in a proximal direction therefrom;
- transluminally navigating the scaffold to a treatment site;
- and
- deploying the support completely within the branch lumen such that all of the at least two fronds extend across the ostium and proximally into the main lumen in a direction opposite to blood flow;
- wherein the fronds have an axial length that is at least 1.5 times the width of the support structure prior to radial expansion.
