A radiopaque identification marker is incorporated into a radiolucent prosthesis, such as a breast implant. The marker denotes data which is ascertainable prior or subsequent to implantation.

The infusion erectile system prosthesis includes a dispensing device implanted in a scrotal sac or subcutaneously in an area adjacent the scrotal sac. The dispensing device includes a reservoir for storing erection stimulating material and a pumping arrangement for actuating movement of the erection stimulating material from the reservoir through a flow tube that joins the penis. The flow tube penetrates a peripheral portion of the penis and communicates with the corpus cavernosum. Infusion of the erection stimulating material into the corpus cavernosum causes an erection to occur. The pump which actuates movement of the erection stimulating material is actuatable manually or electrically.

A ureteral stent kit for inserting a ureteral stent and bypassing obstructions in the ureter comprises an elongated, flexible tubular stent which has a lumen and at least one end set in the form of a hook, a removable tubular guide member sized to fit in the lumen in the stent and having a flexible forgiving tip and a relatively stiff, removable core which is sized to fit within the lumen of guide member and to support the forgiving tip.

A method and apparatus for measuring a dynamic flow rate of a bodily fluid in which the rate of flow is constantly changing includes an inlet to a chamber where flow accumulates. The accumulating fluid is in communication with the base of a sealed vertical column of air. An air pressure transducer in the upper portion of the column of air measures the pressure exerted upon the air by the accumulated fluid. The air pressure corresponds to the volume of accumulated fluid and is manipulated to yield a running indication of the flow rate. The chamber is automatically drained by a drainage conduit when the fluid reaches an upper operating level to reset the apparatus to a lower operating level to be ready to resume taking meaurements.

Method and apparatus for measuring dynamic fluid flow rate

An improved fluid flow meter for measuring a liquid flow rate is disclosed. It comprises a container having an interior cavity, an inlet opening, a vent opening, a first passageway and a second passageway. The first passageway has an upper opening which is sealed by a pressure transducer and has a lower opening which opens into the interior cavity below the inlet and vent openings. A pressure signal produced in the first passageway by liquid in the cavity is converted into a flow rate by a processor which is connected to the pressure transducer. The second passageway has a lower opening in communication with the interior cavity above the lower opening of the first passageway and an upper opening below the upper opening of the first passageway which is connected to a downwardly depending drain tube to drain the level of liquid in the cavity down by siphon action. In one embodiment the vent opening and the second passageway are in communication with the upper portion of a second cavity which is provided below the first cavity and has a lower outlet opening.

Fluid flow meter utilizing pressure sensing

A urine flow meter including a toilet mounted collector is disclosed. The collector has a mouth portion which is dimensioned to fit within a toilet bowl and which has walls which slope downwardly and inwardly to a neck portion. The neck portion extends downwardly from the lower end of the mouth portion to receive urine directed into it from the mouth portion. An aperture is formed in the neck portion and a pressure sender has a lower end in communication with the neck portion. An upper end of the pressure sender is above the neck portion and is connected to a pressure transducer. Urine accumulates in the neck portion until the flow rate into the collector equals the flow rate out through the aperture. The accumulated volume of urine in the neck portion produces an air pressure within the pressure sender which is converted into an electrical signal by the pressure transducer. The pressure transducer output signal is suitable to be processed to provide critical urine flow data.
