Magnetic targeting system and method of using the same
The present invention describes a magnetic targeting system suitable for guiding a biocompatible device to a target area within the body (in vivo) and method of using the same. The system includes a targeting member having a steering material and is attached to the biocompatible device. The system also includes at least one anchoring member constructed and arranged for the inclusion of a magnetic material effective for influencing the traversal of the steering material, in vivo. The magnetically influenced anchoring member interacts with the targeting member such that the biocompatible device is positionable relative to the target area.
1. A magnetic targeting system suitable for facilitating navigation to a target area located in vivo, said system comprising: a targeting member having a first end and a second end, said second end attached to a biocompatible device by a tether and at least said first end includes a steering material influenced by a magnetic field, said first end is constructed and arranged to readily pass through tissue and create a pathway for said targeting member to a target area located in vivo; and at least two anchoring members, each said anchoring member having a proximal end and a distal end, said distal end constructed and arranged to secure to said target area located in vivo, an extender coupled to each said anchoring member, said extender having an open top and a aperture juxtaposed to a bottom end of said extender, wherein said proximal end includes a magnetic material that influences the traversal of said steering material in vivo; said targeting member is of a size which enables said targeting member to pass into first extender through said top of said first extender, through said first extender and out of said first extender through said aperture of said first extender, said targeting member is also of a size which enables said targeting member to pass into second extender through said aperture, through said second extender and out of said second extender through said open top, whereby, the magnetically influenced proximal end of said anchoring member interacts with said first end of said targeting member guiding said targeting member through tissue such that said connected biocompatible device is positioned relative to said target area.
2. The magnetic targeting system of claim 1 , wherein said system includes a real-time feedback mechanism to verify location in vivo of said biocompatible device.
3. The magnetic targeting system of claim 2 , wherein said real-time feedback mechanism includes tactile feedback to verify location in vivo of said biocompatible device.
4. The magnetic targeting system of claim 1 , wherein said magnetic material is an electromagnet.
5. The magnetic targeting system of claim 1 , wherein said magnetic material is a permanent magnet.
6. The magnetic targeting system of claim 1 , wherein said biocompatible device is an implant or surgical instrument.
7. The magnetic targeting system of claim 1 wherein said biocompatible device is formed from a material selected from the group consisting of rigid, semi-rigid, or flexible.
8. The magnetic targeting system of claim 1 , wherein each of said at least two anchor members is a fastening means for attaching to a bony structure and said biocompatible device is an interconnecting means.
9. The magnetic targeting system of claim 1 , wherein said targeting member is formed from a rigid material.
