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.

Medical device used to cause hemostasis of blood vessels using a clip arrangement delivered to a target region through an endoscope. Method for using the device to cause hemostasis of a blood vessel through an endoscope. Medical device including a reversibly closeable clip, a locking arrangement, a control wire, a sheath, and a handle with an actuating trigger. Through the endoscope, hemostatic clipping device that is fully reversible and lockable. Hemostatic clip that reversibly targets and clips bleeding ulcers.

Device and method for through the scope endoscopic hemostatic clipping

The invention in certain aspects relates to a surgical fastener for fastening tissue segments having tissue surfaces. The fastener includes a first fastener member having a base and a piercing element connected to the base for piercing the tissue segments to be fastened, a second fastener member having an opening for receiving and retaining the piercing element of the first fastener member such that the tissue segments to be fastened are retained between the first and second fastening members, and means for promoting adhesion between the tissue surfaces. The invention also relates to related methods and devices for promoting adhesion of tissue segments and preventing fastener migration, especially in an endoscopic procedure for the treatment of GERD.

Tissue fastening devices and processes that promote tissue adhesion

A clipping device includes (a) a shaft defining a lumen therethrough from a proximal end which, during a procedure remains outside the body accessible to a user and a distal end including a distal opening which, during a procedure is inserted into the body to a position adjacent to target tissue; (b) a flexible clip deployable from the distal opening, when in an unconstrained state, the clip assuming a shape selected to clip tissue and prevent a flow of fluid therethrough wherein, while residing within the lumen the clip is held substantially straight by an inner diameter of the lumen; (c) a control wire extending through the lumen from the proximal end to the distal end thereof; and (d) a release mechanism connecting the control wire to the clip during deployment of the clip and disconnecting the control wire from the clip after deployment thereof.

Hemostatic clip and delivery system

A system and method for delivering a surgical clip to a surgical site within a patient's body to compress body, tissue is disclosed. In one embodiment for the system of the present invention, the system includes an endoscopic device that has an endoscope cap disposed on a distal end of the endoscopic device. A surgical clip is removably disposed on an outside surface of the endoscope cap. A deployment device is associated with the surgical clip for deploying the surgical clip from the endoscope cap to the body tissue that is to be compressed. The surgical clip can be a deformable clip that is deployed in a non deformed configuration, and is then deformed so as to apply compression on selected tissue. The surgical clip can be a multi-legged clip, having a plurality of legs that can be locked in a closed position to apply compression to body tissue.

Apparatus and method for compressing body tissue

The present invention provides an apparatus for, and a method of, accurate positioning of endoscopic instruments. Accurate positioning of the instruments is accomplished through the inclusion of a steering ability within the device. After the endoscopic instrument is properly positioned, the present invention may use rapid exchange technology, soft locks, and mechanical locks to maintain the position of the endoscopic instrument. Rapid exchange technology is used to minimize displacement forces present on the guidewire or catheters. Soft locks and mechanical locks resist movements caused by displacement forces.

Method of and apparatus for positioning and maintaining the position of endoscopic instruments

A catheter shaft including a metallic tubular member including a plurality of apertures formed in the tubular wall of the metallic tubular member to provide a desired degree of flexibility to the metallic tubular member. The metallic tubular member includes a tapered region intermediate a region and a second, reduced diameter region relative to the first region.
