Abstract
Systems, methods, apparatuses, and medical devices configured for transmural and/or transdermal magnetic actuation of a tool of a medical device (e.g., without translation of the medical device and/or relative to a platform of the medical device).
Claims25
A medical device comprising:
- a platform;
- a first element comprising at least one of a magnetically-attractive material and a magnetically-chargeable material coupled to the platform;
- and
- a second element comprising at least one of a magnetically-attractive material and a magnetically-chargeable material coupled to the platform;
- and
- a tool coupled to the platform;
- where the tool is configured to be moved substantially without translating the platform by moving an apparatus that is magnetically coupled to the second element but not in physical contact with the tool.
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:
- a first element comprising at least one of a magnet and magnetically-chargeable material;
- and
- a second element comprising at least one of a magnet and magnetically-chargeable material;
- where the first element is movable relative to the second element to move a tool of the medical device without contacting the medical device.
The apparatus of claim 16, where the actuator includes a lever arm coupled to the first element such that moving a portion of the lever arm in a first direction causes the first element to move relative to the second element.
A system comprising:
- a medical device configured to be inserted within a body cavity of a patient, the medical device comprising:
- a platform;
- a first element comprising at least one of a magnetically-attractive material and a magnetically-chargeable material coupled to the platform;
- and
- a second element comprising at least one of a magnetically-attractive material and a magnetically-chargeable material coupled to the platform;
- and
- a tool coupled to the platform;
- where the tool is configured to be moved without translating the platform by moving an apparatus that is magnetically coupled to the second element but not in physical contact with the tool;
- and
- a second platform configured to be magnetically coupled to the first platform through a tissue, the second platform comprising:
- a first element comprising at least one of a magnet and magnetically-chargeable material;
- and
- a second element comprising at least one of a magnet and magnetically-chargeable material;
- where the first element is movable relative to the second element to move a tool of the medical device without contacting the medical device.
A method comprising:
- magnetically coupling an element outside the body cavity of a patient to a tool of a platform disposed in the body cavity of the patient, the tool coupled to the platform;
- moving the tool relative to the platform inside the body cavity by moving the element outside the body cavity.
