20100004591 | MULTI-PLANE MOTION CONTROL MECHANISM - A hand-holdable steering mechanism is used as part of a medical device such as a catheter or an endoscope to allow movement of a steerable distal portion of the catheter or endoscope. The mechanism can include a housing and an actuation system. The actuation system is adapted for one-handed operation by a user, and it allows the user to achieve 360 degree articulation of the steerable distal portion. The actuation system can include a first actuator and a second actuator where the first and second actuators are movable with respect to each other. The first actuator can be at least partially disposed within the second actuator. | 01-07-2010 |
20100121147 | STEERING MECHANISM - A steering mechanism is used as part of a medical device such as a catheter or an endoscope to allow movement of a steerable distal portion of the catheter or endoscope. The mechanism can include a elongate housing and an actuation system. The elongate housing is adapted to be coupled to the steerable portion of the medical device. The actuation system includes an actuator, a first cam, and a second cam. The actuator can move the first cam between a first position and a second position as the actuator is moved along a first axis (or about a second axis different than the first axis). Movement of the first cam between its first and second positions moves the steerable portion of the medical device along a first plane. The actuator can move the second cam between a first position and a second position as the actuator is moved along the second axis (or about the first axis). Movement of the second cam between its first and second positions moves the steerable portion of the medical device along a second plane different than the first plane. | 05-13-2010 |
20110176772 | METHODS AND APPARATUS RELATED TO A DISTAL END OF A SIDE-FIRE OPTICAL FIBER HAVING MULTIPLE CAPILLARY COMPONENTS - In one embodiment, an apparatus may include a first capillary component. A second capillary component may be disposed outside of the first capillary component and may have an inner surface, wherein a portion of the inner surface may be heat-fused to an outer surface of the first capillary component. The apparatus may also include a portion of an optical fiber disposed inside of the first capillary component and the portion of the optical fiber can have an outer surface. A portion of the outer surface of the optical fiber may be heat-fused to an inner surface of the first capillary component. The optical fiber may have a distal surface configured to reflect electromagnetic radiation propagated along a longitudinal axis of a distal end portion of the optical fiber in a lateral direction through the inner surface of the first capillary component and the inner surface of the second capillary component. | 07-21-2011 |
