Abstract

Stents and methods of inserting and removing a stent from an orifice within a body of a patient are disclosed. The stent includes an elongated shaft and a first end portion that includes a first magnet member. The first end position of the stent is disposed within an opening of the orifice. The position of the stent may be manipulated via the use of a second magnet member for generating a magnetic field between the first magnet member and the second magnet member.
