Abstract
A guide for controlling the orientation of a medical device includes a cannula having a lumen therein for the medical device, and a guide member having a passage therein for receiving and directing the medical device, the guide member being movably mounted in the cannula for movement. The guide member can be magnetically responsive to an externally applied magnetic field, or can be magnetically responsive to an externally applied magnetic field when a magnetic medical device is in the passage, and/or it can be mechanically responsive.
Claims16
A magnetically operated guide for controlling the orientation of a medical device, the guide comprising:
- a cannula having a lumen therein for the medical device;
- a magnetic guide member having a passage therein for receiving and directing the medical device, the guide member being movably mounted in the cannula for movement in response to an applied magnetic field, to selectively change the orientation of the passage, and a medical device passing therethrough.
In combination with an elongate magnetic medical device, a guide for controlling the orientation of a medical device, the guide comprising:
- cannula having a lumen therein through which the medical device extends;
- a guide member having a passage therein for receiving and directing an magnetic device,
- the guide being movably mounted in the cannula to move in response to a magnetic field applied to the magnetic medical device in the passage, to selective change the orientation of the passage,
- and a medical device passing therethrough.
A guide for controlling the orientation of a medical device, the guide comprising:
- a cannula having a lumen therein for the medical device;
- a guide member having a passage therein for receiving and directing the medical device, the guide member being movably mounted in the cannula for movement;
- and a mechanism for selectively moving the guide member to selectively change the orientation of the passage, and a medical device passing therethrough.
A guide for controlling the orientation of medical device, the guide comprising:
- a cannula having a lumen therein for the medical device;
- a guide member having a passage therein for receiving and directing the medical device, the guide member having a passage therein for receiving and directing the medical device, the guide member being movably mounted in the cannula for movement;
- and means for selectively moving the guide member to selectively change the orientation of the passage.
A method of reorienting a medical device in the body, the method comprising:
- introducing a guide member at least partially into the subject's body, the guide member comprising a cannula having a lumen therein for the medical device, and a guide member having a passage therein for receiving and directing the medical device, the guide member being movably mounted in the cannula for movement in response to an applied magnetic field, to selectively change the orientation of the passage, and a medical device passing therethrough, so that the guide member is disposed inside the subject's body;
- moving the guide member inside the subject's body to reorient the passage and thus the medical device extending therethrough.
