Abstract
Embodiments of the invention include a medical device for accessing a patient's body portion and used for diagnosis and treatment of medical conditions. Embodiments of the invention may include a particular endoscopic positioning mechanism for placing an endoscope and an additional treatment device within desired body portions in order to assist in diagnosis and treatment of anatomical diseases and disorders. In particular, a medical device according to an embodiment of the invention may include an outer flexible tube and a positioning mechanism configured for rotating one portion of the flexible tube relative to another portion of the flexible tube.
Claims21
1-52. (canceled)
A medical device, comprising:
- an elongate insertion portion, including:
- a proximal portion including a first engagement member,
- a distal portion rotatably coupled to the proximal portion, the distal portion including:
- a laterally-facing window,
- an opening in the laterally-facing window, and
- a second engagement member, the second engagement member engaging the first engagement member, wherein engagement between the first and second engagement members allows rotation of the distal portion relative to the proximal portion through an angle up to at least 360 degrees as one of a proximal force and a distal force is exerted on the distal portion.
An endoscope, comprising:
- an elongate insertion portion, including:
- a working channel,
- a proximal sheath including a first engagement member,
- a distal housing rotatably coupled to the proximal portion, the distal housing including:
- a laterally-facing window,
- a port in the laterally-facing window, the port opening into the working channel, and
- a second engagement member, the second engagement member engaging the first engagement member, wherein engagement between the first and second engagement members allows rotation of the distal housing relative to the proximal sheath through an angle up to at least 360 degrees as one of a proximal force and a distal force is exerted on the distal housing.
A medical device, comprising:
- an elongate insertion portion, including:
- a proximal portion including a first engagement member,
- a distal portion rotatably coupled to the proximal portion, the distal portion including:
- a laterally-facing window,
- an opening in the laterally-facing window, and
- a second engagement member, the second engagement member engaging the first engagement member, wherein engagement between the first and second engagement members sets a limit on the ability of the distal portion to rotate relative to the proximal portion, and allows rotation of the distal portion relative to the proximal portion through an angle up to the limit as at least one of a proximal force and distal force is exerted on the distal portion.
