Abstract: Provided are in vivo imaging agents comprising muteins of hTLc having detectable binding affinity for c-Met or a domain thereof, coupled to a signal generator, and the mutein coupled to a signal generator is disposed in a pharmaceutically acceptable carrier. Also provided are diagnostic methods using in vivo imaging agents comprising muteins of hTLc having detectable binding affinity for c-Met or a domain thereof.

Abstract: A variable length ureteral stent assembly. A central catheter tube forms a ureter stent with a retention structure for anchoring the stent in the ureter particularly within the bladder and kidney. The catheter tube is formed of a shape memory material and at least one of the retention structures includes a end portion of the catheter wrapped spirally into a multiple-turn planar coil having an axis that is transverse to the plane of the structure. The retention structure can then be partially unwound while still providing an anchoring function. Partially unwinding increases the length of an intermediate section of the ureteral stent.

Abstract: A snap action electrical switch is disclosed which includes an actuating plunger slidably mounted within a switch housing, which carries two pairs of circumferentially spaced terminals. The plunger carries two sets of contacts which correspond to respective pairs of the terminals. Each set of the contacts includes a pair of spheres slidingly mounted within a transverse bore provided within the plunger and a spring which yieldably urges the spheres toward opposite ends of the transverse bore. An insulating member is disposed between the terminals and the plungers. One pair of apertures, provided in the insulating member, register with one of the transverse bores when the plunger is in one position and another pair of apertures register with the other transverse bore when the plunger is moved to another position.
