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.

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.

A steerable imaging catheter is provided, including an elongated catheter tube, at least one steering cable extending along the catheter tube to control the movement of the distal end thereof, and a fiber optic cable extending along the catheter tube. The fiber optic cable transmits illumination light from its proximal end to its distal end and transmits an image from its distal end to its proximal end. In one embodiment, two or more steering cables are used, and the catheter tube is configured to have greater flexibility near its distal end than its proximal end so as to concentrate the movement (flexing) of the catheter tube at its distal end. The use of two or more steering cables, together with the catheter tube having varying flexibility, permit better control of the distal end of the catheter tube while reducing undue twisting of the remainder of the catheter tube.

Embodiments of the invention include a medical device with one or more of a variety of features. More particularly, embodiments of the invention relate to endoscopic devices that include one or more features that improve the use of the device. Examples of such features include chamfered edges and corners on, for example, the end effectors, a surface with a controlled finish also on, for example, the end effectors, a jaw with teeth and/or a tang having various configurations, a handle having soft-grip features, and/or an elongate member with varied rigidity. Other examples of such features include a folded portion on, for example, the end effectors and/or a snap-fit clevis assembly.

Endoscopic instruments and methods of manufacture

Embodiments of the invention include a medical instrument with a sealing device. In embodiments, the medical instrument is endoscopic device having a seal between an elongate shaft member and/or on a portion of a handle to, for example, prevent flow communication between a lumen of the elongate member and the external environment.

Instrument with sealing device and methods of advancing fluid therethrough

A device for sealing a cervical opening includes a support structure, and a seal coupled to the support structure, the seal having a surface for abutting against tissue next to the cervical opening, wherein the seal is tiltable relative to the support structure. A device for sealing a cervical opening includes a support structure, and a member coupled to the support structure, wherein the member is inflatable to create a seal for abutting against cervical tissue. A device for sealing a cervical opening includes a seal having a surface for contacting tissue next to the cervical opening, an opening formed on the surface of the seal, and a vacuum port, wherein the opening is in fluid communication with the vacuum port.

Embodiments of the invention include a medical device with one or more of a variety of features. More particularly, embodiments of the invention relate to endoscopic devices that include one or more features that improve the use of the device. Examples of such features include chamfered edges and corners on, for example, the end effectors, a surface with a controlled finish also on, for example, the end effectors, a jaw with teeth and/or a tang having various configurations, a handle having soft-grip features, and/or an elongate member with varied rigidity.

Endoscopic instruments

A handle for controlling a steerable catheter can be aligned so that the direction of movement of the catheter is aligned with the orientation of an image on a monitor. In one embodiment, the handle is axially symmetric, allowing a physician to grasp it such that the movement of the catheter is aligned with an image displayed. In another embodiment, the handle is a grip that is rotatable with respect to the controls of a steerable catheter in order to align the movement with the image displayed.

Handle for steerable catheter

Embodiments of the invention include a medical instrument with a sealing device. In embodiments, the medical instrument is an endoscopic device having a seal between an elongate shaft member and/or on a portion of a handle to, for example, prevent flow communication between a lumen of the elongate member and the external environment.

Various embodiments of a surgical device that combines tissue cutting and spraying in a single device and related methods of use are disclosed. The device may include an elongated member having a proximal end and a distal end, an end effector proximate the distal end of the elongated member, and a nozzle member configured to substantially seal the distal end of the elongated member. The nozzle member may define a flow path in fluid communication between inside and outside of the elongated member when the distal end of the elongated member is sealed with the nozzle member.
