Implant magnet insertion and removal tools
A magnet positioning tool is described for use with an implantable device. The device has a pair of opposing positioning surfaces, at least one of which has a magnet cradle for mechanically engaging an implant magnet associated with a magnet position in the implantable device. The tool also includes a position engagement surface for engaging the implantable device when the magnet cradle is adjacent to the magnet position.
1. A magnet positioning tool for use with an implantable device, the tool comprising:
a pair of opposing positioning surfaces, at least one of the positioning surfaces having a magnet cradle for mechanically engaging an implant magnet in the implantable device, the magnet cradle configured to magnetically engage the implant magnet; and
a stopper mechanism having a position engagement surface, the stopper mechanism projecting from one of the opposing positioning surfaces toward the other opposing positioning surface and configured to prevent the opposing surfaces from approaching each other beyond an insertion distance, the position engagement surface configured to laterally engage the implantable device and to align the implantable device relative to the magnet cradle.
2. A magnet positioning tool according to claim 1 , further comprising:
a magnet ejector projection on a positioning surface opposite to the magnet cradle, the magnet ejector projection protruding from the positioning surface and configured to displace the implant magnet from the implantable device into the magnet cradle when the position engagement surface is engaged with the implantable device.
3. A magnet positioning tool according to claim 1 , further comprising:
a flushing ring on a positioning surface opposite to the magnet cradle for providing flushing fluid to cleanse a magnet position in the implantable device before inserting the implant magnet.
4. A magnet positioning tool according to claim 3 , further comprising:
a flushing channel for providing the flushing fluid to the flushing ring.
5. A magnet positioning tool according to claim 1 , wherein the magnet cradle includes a concave spherical section for mechanically engaging a corresponding convex spherical section portion of the implant magnet.
6. A magnet positioning tool according to claim 1 , further comprising:
a protective layer covering at least a portion of the tool to protect the implant magnet from being damaged by the tool.
7. A magnet positioning tool according to claim 1 , wherein the magnet cradle mechanically engages the implant magnet from beneath the implantable device.
8. A magnet positioning tool according to claim 1 , wherein the magnet cradle mechanically engages the implant magnet from above the implantable device.
9. A magnet positioning tool for use with an implantable device, the tool comprising:
a pair of opposing positioning surfaces, at least one of the positioning surfaces having a magnet cradle for mechanically engaging an implant magnet in the implantable device, the positioning surface opposite to the magnet cradle having a magnetic button configured to magnetically engage the implant magnet; and
a stopper mechanism having a position engagement surface, the stopper mechanism projecting from one of the opposing positioning surfaces toward the other opposing positioning surface and configured to prevent the opposing surfaces from approaching each other beyond an insertion distance, the position engagement surface configured to laterally engage the implantable device and to align the implantable device relative to the magnet cradle.
10. A magnet positioning tool according to claim 9 , wherein the magnet cradle further includes a magnet ejector projection that protrudes from its bottom surface and is configured to displace the implant magnet from the implantable device to the magnetic button when the position engagement surface is engaged with the implantable device.
11. A magnet positioning tool according to claim 9 , further comprising:
a flushing ring on a positioning surface opposite to the magnet cradle for providing flushing fluid to cleanse a magnet position in the implantable device before inserting the implant magnet.
12. A magnet positioning tool according to claim 11 further comprising:
a flushing channel for providing the flushing fluid to the flushing ring.
13. A magnet positioning tool according to claim 9 , wherein the magnet cradle includes a concave spherical section for mechanically engaging a corresponding convex spherical section portion of the implant magnet.
14. A magnet positioning tool according to claim 9 , further comprising:
a protective layer covering at least a portion of the tool to protect the implant magnet from being damaged by the tool.
15. A magnet positioning tool according to claim 9 , wherein the magnet cradle mechanically engages the implant magnet from beneath the implantable device.
16. A magnet positioning tool according to claim 9 , wherein the magnet cradle mechanically engages the implant magnet from above the implantable device.
17. A magnet positioning tool according to claim 1 , wherein the magnet cradle includes a magnetic button on its bottom surface configured to magnetically engage the implant magnet.
