A medical retrieval device includes a handle, two gear racks movably mounted to the handle for longitudinal movement, and a pinion rotatably mounted to the handle so as to engage the two gear racks. Rotation of the pinion moves the gear racks in opposite directions. A basket has at least three legs, an adjacent two of the legs being connected to one of the gear racks, and the remainder of the legs being connected to the other gear rack such that rotation of the pinion displaces the two legs in a first direction and displaces the remainder of the legs in a second direction. Thus rotation of the pinion articulates the basket.

A flexible ureteropyeloscope having a control section and a shaft extending from the control section. The shaft has a front end with a first active deflection section connected in series with a second active deflection section. The control section is adapted to independently deflect the first and second defection sections. The first and second active deflection sections are adapted to deflect such that a distal end of the ureteropyeloscope can be placed in a calyx of a lower pole of a kidney without the need to passively deflect the front end of the shaft against kidney tissue of a patient to reach the calyx of the lower pole.

The invention features a catheter having a catheter body of extended length for insertion within a body of a living being. The catheter also includes an ultrasound imaging device disposed within a distal portion of the catheter body. The ultrasound imaging device generates electrical signals used by an ultrasound imaging system to display a real-time image of tissue surrounding the distal portion of the catheter. The catheter further includes a cutting element, e. g. , an electrode wire or a laser fiber, having a proximal portion disposed within the catheter body. The catheter also includes a mechanism connected to the catheter body that causes the distal portion of the cutting element to extend from the catheter body. The distal portion of the cutting element generates energy in tissue with which it is brought in proximity to form a cut in the tissue. The ultrasound imaging device is positioned relative to the cutting element such that the real-time image produced by the ultrasound imaging system can include the cutting element in relation to the tissue.

An endoscope having a shaft with a semi-rigid tube and a malleable tube. The malleable tube is connected to and extends from a distal end of the semi-rigid tube. The connection of the two tubes includes dimples stamped into the semi-rigid tube that inwardly project into holes in the malleable tube.

A minimally invasive medical retrieval device 10 useful for the removal of objects such as stones, calculi, concretions, foreign bodies and the like from the urinary, biliary, vascular or other systems includes a sheath 12 containing at least three wires 14 adjacently disposed in the sheath 12. At least one of the wires 14, and preferably all of them, can be moved longitudinally with respect to the sheath 12. The wires 14 have distal portions 16 which are formed so as to allow the engaging and removal of the object or objects. The distal portions 16 of the wires 14 preferably form a helical basket 22 or 40 particularly adapted for engaging urinary stones, calculi and concretions. Other grasping and manipulating shapes are useful as well. The wires 14 are substantially wedge-shaped in cross-section and substantially fill the entire cross-sectional area of the interior 26 of the sheath 12. The wedge-shaped wires 14 can be partly contained within a stainless steel cannula 28 positioned in the sheath 12.
