  • Patent number: 6004290
    Abstract: An anchoring system for a urethral catheter (14, 36), and a method of its use, involve a resilient anchor-interval portion (40) of a catheter drainage shaft (42, 42'), positioned between a bladder balloon (26) and a urethral anchoring cuff balloon (44). The anchor-interval portion has a sinusoidal configuration lengthwise thereof which provide a proper linear elastic resilience for allowing the bladder balloon and the urethral anchoring cuff balloon to be separated a substantial distance for impinging against what remains of a prostate gland (20, 28, 32).

  • Patent number: 5976469
    Abstract: A removable lid (10) for an analytical specimen cup (12) of a type for defining a test space (26) with a chemical strip (24) mounted therein includes a selectively-removable protective cover (16) for selectively covering and uncovering an outer surface of a transparent portion of an outer partition (18) forming the test space. The protective cover is formed as one piece with an inner partition to be attached thereto by a dual living hinge (28a and b). The lid is rectangular in shape and includes an elongated magnifying lens (20) which has protrusions extending into blind holes (62) of the inner partition. The magnifying lens extends across the transparent portion of the outer partition. When the protective cover is in a closed position it impinges on the magnifying lens. A peel-off color analysis chart (22) is mounted on an inside surface of the protective cover.

  • Patent number: 5785641
    Abstract: An indwelling urethral catheter sizing system comprises sets of substantially equal length indwelling urethral catheters (14) having various balloon spacings (a, b, c), from bladder balloons (2) to urethral anchoring cuff balloons (36). A method of implanting an indwelling urethral catheter from the sets involves first determining a patient's interballoon urethral segment length, from his bladder to his bulbous urethra immediately downstream of what remains of his prostate gland. A urethral sizing catheter having a balloon spacing corresponding to the interballoon urethral segment length is inserted in the patient to determine the clinical length of the patient's urethral tract from his bladder to his penile meatus. A male indwelling urethral catheter is then chosen from the sets having a balloon spacing corresponding to the patient's interballoon urethral segment length and the clinical length determined with the urethral sizing catheter.

  • Patent number: 5713877
    Abstract: An indwelling magnetically actuable urinary catheter (35) involves the molding of a valve housing (32) to a catheter drainage shaft (16) by using a drainage-valve-cavity mandrel (22) and two inflation-valve-cavity mandrels (24). The drainage-valve-cavity mandrel (22) forms a spring seat having a built in integral bypass and a valve seat. An elongated one-piece valve popper (50) of Ferro-magnetic material has an enlarged, rounded, bulbous head facing the valve seat and an elongated smaller diameter portion directed toward the spring seat for engaging the tapered spring supported by the spring seat.

  • Patent number: 5595187
    Abstract: An analytical specimen cup system (10) includes a lid (14) comprising outer and inner partitions (42, 40) for defining a test space (44) having a chemical test strip (30) mounted therein. The inner partition defines a raised test-strip shelf (61) on which the chemical test strip is mounted, a sump (64) with a floor (62) positioned substantially below the raised shelf, and an opening-defining member (48) for defining an opening (50) to allow test fluid to be transferred from an analytical specimen cup (12) to the test space. A mouth (60) of the opening is vertically positioned intermediate the raised test-strip shelf and the sump floor. In one embodiment the analytical specimen cup has a membrane (24) covering its mouth (18) and is sterilized separate from the lid. The inner partition includes a specimen-release device (52) for uncovering the opening of the opening-defining member as well as for piercing the membrane.
