Abstract: A tip element for a lithotripter is provided. The tip element includes a proximal end configured for attachment to a waveguide of the lithotripter and a distal end configured for placement against at least one urinary tract stone. The lithotripter transmits energy from the tip element to the at least one urinary tract stone to break up the at least one urinary tract stone into fragments. The tip element may further include a tip element passage that extends between the proximal end and the distal end. The tip element passage communicates with a lumen of the waveguide for at least one of suctioning and irrigating a urinary tract. The distal end has one or more sharp edges to maintain contact between the at least one urinary tract stone and the distal end during suctioning. The distal end may be configured to limit the size of fragments from the at least one urinary tract stone drawn into the tip element passage during suctioning.

Abstract: A medical instrument having a lighting system for illuminating a target area, the system comprising a light source and associated power controller, the system being configured to move from a first illumination mode to a second illumination mode based on a sensed or determined changed condition, such as predetermined temperature and/or change in a scene or brightness signal, or lack of change, from an image sensor that may be associated with the instrument.

Abstract: An apparatus is presented comprising an endoscope including a flexible shaft which has an active deflection section at a distal tip, a handle connected to a proximal end of the flexible shaft, a platform mounted to a top portion of the handle and oriented substantially in line with the longitudinal axis of the proximal end of a straight portion of the flexible shaft to provide a substantially straight entry into a working channel of the flexible shaft for an output accessory, a stone retrieval device insertable into the proximal end of the working channel of the endoscope, a lithotripsy shaft including one or more guide features at a distal end of the lithotripsy shaft to facilitate passage of wires or filaments of the stone retrieval device there through, and a lithotripsy shaft driver attached to the platform for driving the lithotripsy shaft under power.

Abstract: An apparatus and method are presented comprising a stone retrieval device insertable through a proximal end of a working channel of an endoscope to retrieve a stone at a distal end of an endoscope shaft, and a lithotripsy shaft with a distal tip including one or more guide features to accommodate passage there through of the stone retrieval device and insertable through the proximal end of the working channel of the endoscope, wherein the stone retrieval device extends from the distal end of the endoscope shaft through the lithotripsy shaft.

Abstract: An oval or ovoid electrode is used in a resectoscope. A longer dimension of the electrode preferably extends in a direction that is perpendicular to the direction in which the electrode is moved during tissue resection.

Abstract: An improved bipolar resection device provides an intuitive finger grip control in a smaller sheath package. Bipolar electrode wires occupy less space by extending in a closely abutting relationship along the sheath and exiting in a one above the other orientation that provides a reduced profile, allowing for better visualization during resection. In various embodiments, resection motion is provided through a rotational sweep transverse to the longitudinal axis of the resection device and may include push/pull motion. The sheath may be oval in shape and the bipolar electrode connected to the bipolar electrode wires having a narrow cross-section to improve resection site visualization.
