Abstract: The present invention is directed to a cap for a medicine bottle for monitoring a patient's medicine compliance. It involves weighing a container of medicine with cap which includes scale means located therein which is connected to a computer chip with a display unit also located in or on the cap. The chip may store the starting weight or tare weight, plus total weight and when the container or medicine is picked up by the cap at any time, actual weight is fed to the chip. The computer chip may then determine the difference between the starting weight and/or display actual amount of medicine remaining or consumed. The container of medicine is reweighed from time to time with the cap and the chip may compare actual weight with compliance required weight to determine compliance and the cap may visually display the compliance results on the display unit to inform the patient. An optional audio assist may direct the patient to "call the doctor" if a significant compliance deviation is recognized.

Abstract: The present invention is directed to a ureteral catheter stent which includes an elongated, relatively flexible, hollow tubular member having a plurality of drainage openings extending through a wall thereof and having two end portions each end portion being in the form of a hook and having at least one male and/or female interlocking unit formed into the end of at least one hook. The ureteral catheter stent of the present invention is used in conjunction with a follower which is interlocked therewith during insertion so that rotation or movement of the follower will create exact rotation of the stent on the guide wire during insertion so as to accurately and easily enable the user to place the hook of the stent in the direction desired. Additionally, the ureteral catheter stent of the present invention may have other sources for inserting other devices, rods, tubes of the like into the stent at a future date, without having to locate the lower end of a hook and without having to straighten the hook itself.
