Surgical scissors with bipolar coagulation feature
A bipolar electrosurgical scissors for use in open or endoscopic surgery has a pair of opposed blade members pivotally joined to one another and to the distal end of the scissors itself by a rivet which extends through a insulated bushing member. Each of the blade members comprises a blade support and a blade itself, each fabricated from metal, such as stainless steel. The blades are affixed to their associated supports by means of a suitable adhesive or adhesive composite material such as a fiberglass reinforced epoxy exhibiting dielectric properties. Cutting is performed, steel-on-steel, without causing a short circuit between the two blade supports which themselves function as the bipolar electrodes.

Interfacial stent and method of maintaining patency of surgical fenestrations
InactiveUS20070179426A1Keep openImprovement endStentsHeart valvesThird ventriculostomyInsertion stent
A method according to one embodiment for maintaining patency of an opening inside the human body comprises introducing a radially self-expanding hollow stent into the opening through an endoscope that radially compresses the stent, wherein the stent has enlarged ends and a reduced intermediate portion. The stent is introduced into the opening such that its intermediate portion extends through the opening and the enlarged ends are positioned outside of the opening. Once deployed, the stent expands such that the enlarged ends of the stent abut against opposing faces of the opening to resist dislodgement of the stent from the opening after expansion. The stent is preferably biodegradable, such that it is eliminated from the surgical site over a period of weeks to months, by which time the patency of the opening is more assured. The method can be used in combination with, for example, an endoscopic surgical method such as endoscopic third ventriculostomy for treating hydrocephalus of a brain.

Robotic module for natural orifice transluminal endoscopic surgery (NOTES)
ActiveUS20130012821A1Little strengthSufficient forceSurgical manipulatorsSurgical robotsIn vivoActuator
A miniature in-vivo robotic module to be used for conducting dexterous manipulations on organs and other target entities in a patient's abdominal or peritoneal cavity as part of Natural Orifice Transluminal Endoscopic Surgery (NOTES) is disclosed in this invention. The robotic module is a serial manipulator consisting of seven cylindrical links and six actively controllable rotational degrees of freedom, thereby enabling an end effector equipped with a laparoscopic type instrument to assume a commanded position and orientation within the robot's workspace. After overtube navigation starting from a natural orifice or preexisting wound, the module must be anchored and guided to a designated location along the inner abdominal cavity wall. This is accomplished via magnetic coupling forces between internal embedded magnets and magnets fixed to the end of a different robotic manipulator located external to the patient.

Laparoscopic Cholecystectomy With Fluorescence Cholangiography
Use of near-infrared fluorescence imaging in performing an endoscopic surgery, such as laparoscopic cholecystectomy. A composite video image of the surgical field (e.g. the biliary anatomy) is shown on a display screen. The composite video image combines a visible color image and a fluorescence image of the surgical field. Using various techniques, selective fluorescence imaging of a particular area of interest in the surgical field is made possible. For example, in a cholecystectomy procedure, the biliary ducts may be the particular area of interest for the selective fluorescence imaging.
