  • Systems and methods for dynamic optical imaging
    Patent number: 7376455
    Abstract: A medical system includes a catheter having an elongated tubular member and an inner core slideably received within the elongated member. The inner core includes an imager on a distal end and is coupled with a control system and an imaging system. The inner core is configured to scan the interior of a lumen by radially rotating around a center axis and axially translating along the center axis while within the elongated member. The medical system is configured to dynamically image a body lumen at a high speed in order to allow for optical imaging in a safe manner without long durations of blood sequestration and displacement. The medical system is configured to obtain three dimensional images of the body lumen with as little as one dimensional scanning of the lumen. Images of the lumen can be stored and viewed at a desired rate after scanning.

  • Steerable sphincterotome and methods for cannulation, papillotomy and sphincterotomy
    Patent number: 7371237
    Abstract: 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.
