摘要： Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and reusable 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： A retrieval device may have a contracted state and an expanded state. The retrieval device may include a sheath and at least three support members. Each of the support members may have a first portion with a first cross-sectional shape and a second portion with a second cross-sectional shape different from the first cross-sectional shape. A proximal end fixed of each of the support members may be coupled to the sheath, and a distal end may be movable relative to the sheath. The retrieval device may further include at least three movable members movable relative to the support members. Each movable member may extend through a lumen of one support member of the at least three support members and through a lumen of a different support member of the at least three support members.

摘要： A scope device includes a shaft, a deflectable portion, and a handle portion. The shaft is inserted through a body lumen to a target area within a body. The shaft defines first and second lumens extending along a proximal portion thereof. The first and second lumens are merged to form a common lumen along a distal portion thereof via a fitting having a structure which, when connected to the first and second lumens, converge the first and second lumens toward the common lumen. The deflectable portion is connected to the distal end of the shaft and includes a channel aligned with and in communication with the common lumen. The handle portion includes a connector having a first hub including a first channel open to and in communication with the first lumen and a second hub including a second channel open to and in communication with the second lumen.

摘要： A system includes a scope device, an adapter and an outer sheath. The device includes a scope cap and a shaft extending longitudinally from a proximal end to a distal end. The shaft includes a working channel. The cap is coupled to the distal end such that cap's inlet opening is in communication with and in alignment with the channel. The adapter has a substantially tubular body mountable over the cap such that a distal chamber defined via the adapter and the cap is open to and in communication with the opening thereof so that, when a negative pressure is applied through the channel, a suction force applied is applied through the distal chamber to draw the stone one of into and against the chamber from the area. The sheath delivers a fluid to the area via a space extending between sheath's interior and shaft's exterior.

摘要： A system includes an adapter and an insertion device. The device includes a shaft extending longitudinally from a proximal end to a distal end. The shaft includes first and second working channels extending therethrough. The adapter includes a proximal portion coupled to the distal end and a distal portion defining a chamber receiving a stone. The proximal portion includes an outlet extending through a portion thereof positioned so that, when the adapter is in desired alignment, a fluid supplied to the first channel is directed out of the adapter via the outlet to an area surrounding the adapter. The adapter further includes an inlet channel extending longitudinally through the proximal portion to a distal opening which is open to the chamber. The inlet channel is configured so that, when negative pressure is applied thereto, the fluid is drawn through the distal opening through the inlet channel to the second channel.

摘要： Guidance systems and associated methods are disclosed. One method comprises: receiving macroscan data prior to an operation; defining a body information model from the macroscan data; positioning a navigation component in the body during the operation; generating microscan data with the navigation component; correlating a location in the macroscan data with a location in the microscan data in the body information model; and/or modifying the body information model by combining an image in the microscan data with an image in the macroscan data.
