Abstract
A prosthesis includes a radially expansible scaffold in at least two circumferential anchors extending from the scaffold. The prosthesis is placed across an os between a main body lumen and a branch lumen. The scaffold is expanded within the branch lumen and the circumferential anchors deformed outwardly to conform to the wall of the main body lumen. Optionally, a second prosthesis may be placed within the main body lumen after the first prosthesis has been deployed.
Claims22
A prosthesis for placement at an os opening from a main body lumen to a branch body lumen;
- said prosthesis comprising:
- a radially expansible scaffold;
- and
- at least two circumferential anchors extending axially from an end of the scaffold, said anchors adapted to extend axially into and expandably circumscribe at least one-half of the main vessel wall when the scaffold is implanted in the branch lumen with said one end adjacent the os.
A method for deploying a prosthesis across an os opening from a main body lumen to a branch body lumen, said method comprising:
- positioning the prosthesis so that a scaffold lies within the branch body and at least two circumferential anchors extend into the main body lumen;
- radially expanding the scaffold to implant said scaffold in the branch body lumen;
- and
- circumferentially deforming the anchors to circumscribe at least a portion of the main vessel wall and open a passage through the anchors.
