摘要：
A magnetic delivery system for delivering a magnetizable particle to a location in a body, the device includes a magnetizable object implanted in the body, wherein the magnetizable object includes a plurality of segments distributed throughout the magnetizable object and wherein the segments are configured to provide a magnetic gradient for attracting the magnetizable particle and an external source of a magnetic field capable of (i) magnetizing the magnetizable particle and (ii) increasing a degree of magnetization of the magnetizable object and thereby creating the magnetic gradient. A drug delivery system including the magnetic delivery system and a magnetizable particle associated with a therapeutic agent and/or a cell. A cell delivery system based on the magnetic delivery system and a magnetizable particle associated with a cell. A method of using the magnetic delivery system for delivery of a therapeutic agent and/or a cell to a targeted location in a body.
