Abstract
An anchoring device for use within a vascular structure includes a head having a first surface and a second surface meeting at a common plane, and an anchor including a shaft having a longitudinal axis, a first end connected at a junction to the first surface of the head, and a free end. A harbor space is bounded by the shaft of the anchor, the first surface of the head, a first theoretical plane perpendicular to the longitudinal axis at a spaced distance from the junction and a second theoretical plane tangential to the head at a point in the common plane. The harbor space has an are sufficient to receive a portion of a stented device therein.
Claims10
A valvular prosthesis for use within a cardiovascular structure, comprising:
- a prosthesis having an outer portion for engagement with the cardiovascular structure and an inner portion disposed opposite the outer portion;
- and
- an anchoring device having a plurality of disc-shaped members and a plurality of nodules, the disc-shaped members each having first and second end surfaces and a side surface spanning therebetween, each of the disc-shaped members being connected to an adjacent disc-shaped member via a connector arm that extends from the side surfaces thereof, the plurality of nodules each projecting from the first end surface of a respective one of the disc-shaped members, and the second end surfaces of the disc-shaped members being engaged with the inner portion of the prosthesis.
A method of anchoring a stented device, comprising:
- guiding a catheter to a deployment location within the cardiovascular system of a patient, the catheter having contained therein, in a contracted configuration, an expandable stented device including a plurality of cells, the deployment location including at least one anchoring device with a head projecting radially inwardly within the deployment location, the head having a rounded body with at least two surfaces that meet each other at a common plane;
- removing the stented device from the catheter at the deployment location;
- expanding the stented device such that the head of the anchoring device extends through one of the cells of the stented device;
- at least partially contracting the stented device after the expanding step;
- adjusting the stented device along the deployment location after the step of at least partially contracting the stented device to reposition the stented device relative to the head;
- and
- re-expanding the stented device after the adjusting step so that the head extends through another one of the cells of the stented device.
