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.

Embodiments of the disclosure may include a method for providing access within a patient that may include inserting a medical device through an opening of the patient. The medical device may include an overtube having a lumen and a slot and an elongate member disposed within the lumen of the overtube, wherein the elongate member may include an expandable member configured to expand and collapse. The method may further include positioning the medical device proximate a site in the patient, positioning the overtube relative to the elongate member such that a portion of the expandable member faces the slot, and the slot faces the site, and expanding the portion of the expandable member out of the slot and toward the site.

An apparatus includes a flexible elongate member that defines a lumen and is configured to be inserted within a body passageway of a patient. The flexible elongate member includes a proximal portion, a distal portion, and a medial portion disposed between the proximal portion and the distal portion. The distal portion is movable between a substantially linear configuration and a curved configuration. A stiffening member is coupled to the flexible elongate member. The stiffening member is movable to a selected location along a length of the flexible elongate member to provide modified flexibility to the selected location of the flexible elongate member. The stiffening member may include a first portion and a second portion, the first portion having a first stiffness and the second portion having a second stiffness different than the first stiffness. The stiffening member may be disposed within a lumen or at an exterior portion of the flexible elongate member.

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. The housing also includes a micro-defects portion within the transparent material of the housing. The micro-defects portion is configured to provide a selected output shape of a beam of light produced by the light source.

In one embodiment, an endoscope includes an elongate member having a proximal end portion and a distal end portion. The distal end portion is configured to be inserted into a body lumen. An electrical component is disposed within the distal end portion of the elongate member and configured to produce a signal. An elongate conductive mechanical component has a proximal end portion and a distal and portion. The distal end portion of the elongate conductive mechanical component is electrically coupled to the electrical component and configured to conduct the signal or electrical power from/to the electrical component to/from the proximal end portion of the elongate conductive mechanical component.
摘要:
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.
摘要:
An apparatus includes an optical fiber extending from a proximal end to a distal end. The optical fiber may include a cladding layer circumferentially disposed about a core layer and a substantially spherically shaped portion at the distal end. The apparatus may also include a first coating circumferentially disposed on a first length of the cladding layer, and a second coating circumferentially disposed on a second length of the cladding layer. The second length may extend distally from a region proximate the distal end of the first coating.
摘要:
Embodiments of the invention include a device to provide working access to a surgical site in a patient. The device may include a port component including an elongate member configured to pass through an opening in the patient. The elongate member may include a bore extending between a distal end and a proximal end of the elongate member. The port component may also include an expandable member disposed on the elongate member that may perform dissection and may form a seal to maintain insufflation pressure in a working space. The device may also include an insert component configured to be removably received inside the bore in the elongate member of the port component. The insert component may include at least one lumen that may removably receive at least one working instrument.
