  • Patent number: 10410534
    Abstract: Disclosed are various embodiments for assisting students in a development of critical thinking skills pertinent to solving problems. An educational system may access predefined education modules from memory that facilitate an interaction between a student and a user interface. The user input provided by the student is measured in real-time such that an analysis platform may conduct a real-time evaluation of the user input. A heat map that visually depicts skills of the student is generated and may be rendered in an administrative user interface that may be accessed by a teacher or similar personnel.

  • Publication number: 20170231475
    Abstract: Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and resuable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.

  • Patent number: 9521942
    Abstract: An apparatus according to one embodiment includes an endoscope tip including a housing that is monolithically formed of a transparent material. At least one optical component is at least partially encased within the housing. The optical component can be, for example, a light source, a fiber optic, an imaging sensor, a lens, a reflector or a light shield. In another embodiment, an apparatus includes an endoscope having a distal end portion that includes a housing. The housing is monolithically formed with a transparent material and a light source is at least partially encased within the housing.

  • Patent number: 9380930
    Abstract: 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).

  • Patent number: 8926636
    Abstract: In some embodiments, an apparatus includes a handle and an elongate member coupled to the handle. The elongate member has a first portion, a second portion and a third portion. The first portion of the elongate member extends from the handle and defines a first longitudinal axis. The second portion of the elongate member extends from the first portion and defines a second longitudinal axis. The first longitudinal axis and the second longitudinal axis define a first angle and a first plane. The third portion of the elongate member extends from the second portion of the elongate member and defines a third longitudinal axis. The third longitudinal axis and the second longitudinal axis define a second angle and a second plane. The second plane is non-parallel with the first plane.
