Abstract
Embodiments of apparatuses, and methods and systems including apparatuses, configured to be magnetically coupled to a medical device within a body cavity of a patient. Some embodiments include one or more elements comprising at least one of a magnetically-attractive and magnetically-chargeable material; and a bumper extending around the one or more elements and configured to reduce the strength of a magnetic field of the one or more elements.
Claims21
An apparatus comprising:
- a platform configured to be magnetically coupled to a medical device disposed within a body cavity of a patient through a tissue, the platform comprising:
- one or more elements comprising at least one of a magnetically-attractive material and a magnetically-chargeable material;
- and
- a bumper extending around the one or more elements, the bumper comprising:
- a magnetically-permeable material spaced apart from the one or more elements, the magnetically-permeable material configured to reduce the strength of a magnetic field of the one or more elements in at least one direction outside the bumper;
- and
- a magnetically-inert material surrounding at least a portion of the magnetically permeable material.
An apparatus comprising:
- a platform configured to be magnetically coupled to a medical device disposed within a body cavity of a patient through a tissue, the platform comprising:
- one or more elements comprising at least one of a magnetically-attractive material and a magnetically-chargeable material;
- and
- a bumper extending around the one or more elements, the bumper comprising:
- a magnetically-permeable material spaced apart from the one or more elements, the magnetically-permeable material configured to reduce the strength of a magnetic field of the one or more elements in at least one direction outside the bumper.
An apparatus comprising:
- a platform configured to be magnetically coupled to a medical device disposed within a body cavity of a patient through a tissue, the platform comprising:
- two or more elements each comprising at least one of a magnetically-attractive material and a magnetically-chargeable material;
- and
- a bumper extending around the two or more elements, the bumper comprising:
- a magnetically-permeable material spaced apart from the two or more elements, the magnetically-permeable material configured to reduce the strength of a magnetic field of the one or more elements in at least one direction outside the bumper.
A system comprising:
- a first platform configured to be inserted within a body cavity of a patient, the first platform comprising:
- one or more elements comprising at least one of a magnetically-attractive material and a magnetically-chargeable material;
- and
- a second platform configured to be magnetically coupled to the first platform through a tissue, the second platform comprising:
- one or more elements comprising at least one of a magnetically-attractive material and a magnetically-chargeable material;
- and
- a bumper extending around the one or more elements, the bumper comprising a magnetically-permeable material spaced apart from the one or more elements, the magnetically-permeable material configured to reduce the strength of a magnetic field of the one or more elements in at least one direction outside the bumper.
