The present invention relates to methods and devices for performing endoscopic cannulation, papillotomy and sphincterotomy and similar procedures. According to the present state of the art, endoscopic cannulation of the common bile duct and papillotomy and similar procedures are accomplished by advancing the device into an endoscope / duodenoscope so that the distal tip of the device exits the endoscope adjacent the sphincter muscles at the Papilla of Vater. The endoscope mechanisms are then manipulated to orient the distal tip of the device to the desired position for proper cannulation of the duct. Due to inconsistencies in, for example, the sphincterotome, anatomy, and endoscope manipulation, it is difficult to accurately and consistently position the sphincterotome for proper cannulation. The steerable sphincterotome of the present invention allows the physician to control the position of the distal tip of the device independently of the endoscope and adjust for inconsistencies in the device and the anatomy. According to the present invention, the handle to which the cutting wire is attached is freely rotatable relative to the catheter. The handle, secured to the cutting wire but rotatable relative to the shaft of the catheter, provides a mechanism to rotate the wire, transmitting the force to rotate the device tip. With the handle rotating independently of the shaft at the proximal end, the force can be applied directly to the distal tip without twisting the entire shaft. Also a rotation lock to maintain the orientation of the tip and / or a rotation marking, to indicate the amount of rotation may be included.

Methods and apparatus provide continuous guidance of endoscopy during a live procedure. A data-set based on 3D image data is pre-computed including reference information representative of a predefined route through a body organ to a final destination. A plurality of live real endoscopic (RE) images are displayed as an operator maneuvers an endoscope within the body organ. A registration and tracking algorithm registers the data-set to one or more of the RE images and continuously maintains the registration as the endoscope is locally maneuvered. Additional information related to the final destination is then presented enabling the endoscope operator to decide on a final maneuver for the procedure. The reference information may include 3D organ surfaces, 3D routes through an organ system, or 3D regions of interest (ROIs), as well as a virtual endoscopic (VE) image generated from the precomputed data-set. The preferred method includes the step of superimposing one or both of the 3D routes and ROIs on one or both of the RE and VE images. The 3D organ surfaces and routes may correspond to the surfaces and paths of a tracheobronchial airway tree extracted, for example, from 3D MDCT images of the chest.

A casing of an endoscopic manipulating head assembly is largely constituted by and dividable into a main cover section adapted to support an operating means of an angulation control mechanism and a grip cover section provided between the main cover section and an insertion tube of the endoscope. Both of the main cover section and the grip cover section are formed of a synthetic resin material. A support plate of a rigid metal is provided internally of the manipulating head assembly to support the angulation control mechanism. A plural number of passage-forming tubular structural members are successively connected within the grip cover section for passing internal components to and from the insertion tube of the endoscope. The support plate is connected to one of the tubular structural members which is located at the proximal end of the grip cover section. A first anti-twist lock portion is formed between the support plate and joined end portions of the main and grip cover sections, while a second anti-twist lock portion is formed between the grip cover section and joined end portions of the tubular structural members.

A device for creating endoscopic operating space includes an external cannula, an internal cannula disposed in the external cannula, and an expandable retractor disposed at a distal end of the device and cooperable with the external cannula and the internal cannula. The expandable retractor is displaceable between an unexpanded position and an expanded position. An actuator is cooperable with the expandable retractor to displace the expandable retractor between the unexpanded position and the expanded position.

Systems and methods for tracking shape and orientation of an endoscope employ motion tracking sensors to track locations on the endoscope for use in determining real time shape and distal end orientation for display during navigation of the endoscope. An example system includes sensor units distributed along the endoscope and a control unit. The sensor units track motion of the endoscope locations and transmit resulting tracking data to a control unit. The control unit processes the tracking data to determine shape of the endoscope and orientation of the distal end of the endoscope. The control unit generates output to a display unit that causes the display unit to display one or more representations indicative of the shape of the endoscope and orientation of the distal end of the endoscope for reference by an endoscope operator during an endoscopic procedure.
