  • Magnetic anatomical marker and method of use
    Patent number: 6173715
    Abstract: An anatomical marker uses a permanent magnet to indicate a selected location within a patient. The magnet is enclosed within a non-degradable envelope and is coupled to a retention member that is preferably manufactured from a biodegradable material, such as a polyglucuronic acid based material. The retention member may include one or more barbs to retain the anatomical marker in the selected location. An insertion tool, usable with an endoscope, can insert the anatomical marker. A retention magnet is fixedly attached to the insertion tool and holds the anatomical marker in place due to the attractive magnetic forces between the retention magnet and the marker magnet in the non-biodegradable envelope.
