Abstract
An illustrative stent includes an elongated tubular member comprising at least one strut forming a tubular wall having a plurality of cells extending through a thickness of the tubular wall. The elongated tubular member may be configured to move between a radially collapsed configuration and a radially expanded configuration. A coating may be disposed on the elongated tubular member and spanning at least some of the plurality of cells. One or more magnetic components may be disposed on or within the coating.
Claims20
A stent, the stent comprising:
- an elongated tubular member comprising at least one strut forming a tubular wall having a plurality of cells extending through a thickness of the tubular wall, the elongated tubular member configured to move between a radially collapsed configuration and a radially expanded configuration;
- a coating disposed on the elongated tubular member and spanning at least some of the plurality of cells;
- and
- one or more magnetic components disposed on or within the coating.
A stent, the stent comprising:
- an elongated tubular member comprising at least one strut forming a tubular wall having a plurality of cells extending through a thickness of the tubular wall, the elongated tubular member configured to move between a radially collapsed configuration and a radially expanded configuration;
- a coating disposed on the elongated tubular member and spanning at least some of the plurality of cells;
- and
- a plurality of magnetic components embedded within the coating, the plurality of magnetic components including a silicone base and carbonyl iron;
- wherein in response to an applied magnetic field, the one or more magnetic components are configured to move radially inward and/or radially outward relative to the at least one strut.
A method for preventing occlusion of a stent, the method comprising:
- delivering a stent to a target location within a body, the stent comprising:
- an elongated tubular member comprising at least one strut forming a tubular wall having a plurality of cells extending through a thickness of the tubular wall, the elongated tubular member configured to move between a radially collapsed configuration and a radially expanded configuration;
- a coating disposed on the elongated tubular member and spanning at least some of the plurality of cells;
- and
- one or more magnetic components disposed on or within the coating;
- positioning a console configured to supply a magnetic field exterior to the body and adjacent to the target location;
- and
- periodically activating the magnetic field;
- wherein in response to the magnetic field being applied, the one or more magnetic components are configured to move radially inward and/or radially outward relative to the at least one strut.
