Abstract
Methods and systems are provided for maintaining alignment of an articulated medical device which allows a reference element or reference trajectory to be set at a location within a subject. A medical tool can be guided through the device and facilitating medical procedures, including endoscopes, cameras, and biopsy tools, to a target when the articulated medical device is subjected to external forces that cause a deviation in the trajectory towards the target.
Claims22
A medical apparatus comprising:
- a bendable body;
- at least one control wire slideably situated in the bendable body;
- one or more sensor;
- and
- a controller for causing movement of the medical apparatus;
- wherein the controller:
- determines a reference element to a region of interest;
- determines an acceptable deviation from the reference element;
- and,
- causes the medical apparatus to bend, rotate, and/or translate in order to maintain a trajectory toward the region of interest that stays within the acceptable deviation.
7 more elements
A method for targeting a region of interest in a subject, comprising:
- providing a medical apparatus comprising:
- a bendable body;
- at least one control wire slideably situated in the bendable body;
- and
- one or more sensor;
- advancing the medical apparatus to a first location in the subject;
- determining a reference element, the reference element associated with the bendable body location;
- defining an acceptable deviation between the first location and the reference element;
- and
- countering external forces on the bendable body to maintain a location or position within the acceptable deviation.

A method of treating a subject comprising:
- providing a medical apparatus comprising:
- a bendable body;
- at least one control wire slideably situated in the bendable body;
- and
- one or more sensor;
- advancing the medical apparatus to a first location in the subject;
- determining a reference element, the reference element associated with the bendable body location;
- defining an acceptable deviation between the first location and the reference element;
- countering external forces on the bendable body to maintain a location or position within the acceptable deviation;
- inserting a treating tool into the medical apparatus to a location within the acceptable deviation from the reference element;
- and
- treating the subject.
