  • Patent number: 6623469
    Abstract: The invention is a refastenable mechanical fastening system, made of free formed prongs joined to a substrate. The prongs taper and are nonperpendicularly oriented relative to the plane of the substrate. Each prong has an engaging means projecting laterally from the periphery of the prong. The free formed prongs are manufactured by the process of depositing liquid material onto a moving substrate, stretching the liquid material in a direction parallel to the plane of the substrate and severing the stretched material to form the distal end and engaging means of the prong. The advantageous usage of the fastening system in an article of manufacture, such as a disposable absorbent garment, specifically a diaper, is also disclosed.

  • Patent number: 5735815
    Abstract: A pulsed fluid jet surgical instrument includes a cannula extending from a handpiece, the cannula emitting a pulsed fluid jet for cutting and emulsification purposes, and also providing suction for aspiration and evacuation of the fluid and tissue. A pressure intensifier piston arrangement receives fluid at relatively low pressure, and operates reciprocally and reiteratively to pump the fluid through the jet needle in a series of high pressure pulses, each having a nearly rectangular pressure waveform. The pressure intensifier piston is T-shaped, including a broad end which divides a drive bore into a driving chamber and a retracting chamber. A bistable valve is connected to admit high pressure gas into the actuating chamber, driving the piston to translate. The narrow end of the piston is disposed in a fluid pumping chamber connected to a supply of fluid.

  • Patent number: 5624411
    Abstract: A method for making an intravascular stent by applying to the body of a stent a therapeutic substance and then overcoating the therapeutic substance with a porous polymer. The inclusion of a porous polymer in intimate contact with a drug on the stent allows the drug to be retained on the stent during expansion of the stent and also controls the administration of drug following implantation. The adhesion of the coating and the rate at which the drug is delivered can be controlled by the selection of an appropriate bioabsorbable or biostable polymer.

  • Patent number: 5622530
    Abstract: Methods for conducting controlled environment electrotransport are described. The methods generally concern control of the ionic environment of the active electrode reservoir, in an electrotransport system. This control may be utilized, for example, to maintain a constant extraneous ion presence, such as pH. It may also be applied in a preferred manner to maintain selected control over the delivery rate of a target species, in time, in the presence of extraneous ions. Apparatus usable to provide for controlled environment electrotransport are also described. In general the apparatus comprises an electrotransport system including an active electrode reservoir having therein both a primary electrode arrangement and a secondary electrode arrangement, with a control arrangement for selected operation of both.

  • Patent number: 5618266
    Abstract: An apparatus for treating an occlusion or constriction, such as a stenosis in a blood vessel or other conduit in the body, as well as an apparatus for treating bodily diseases (e.g. a tumor or cancerous area) occurring around a conduit or duct in the body. The apparatus includes a catheter which is correctly positioned within a conduit of the body utilizing a guide wire. The guide wire would pass through the entire length of the catheter, or a portion of the length of the catheter, and would exit the catheter through a constriction plug affixed to the end of the catheter. A radioactive treatment source wire is then introduced into the catheter and is maneuvered to the site of treatment. The constriction plug is provided with an internal diameter which is less than the diameter of the radioactive source wire, but greater than the diameter of the guide wire. This construction would prevent the radioactive source wire from remaining in the body after the catheter has been removed.

  • Patent number: 5616124
    Abstract: An infusion system with an air-in-line sensor is provided with improved apparatus and method for quickly and easily clearing small quantities of undissolved gas such as air from the sensor detection field. The infusion system includes an infusion pump having control components responsive to the air-in-line sensor to activate an alarm and/or to cease pump operation when undissolved gas is detected. A "clear air" key or switch is provided on the pump for actuation by medical personnel to operate the pump in a manner delivering a small pulse of the infusion liquid to move a small detected quantity of gas past the air-in-line sensor. The system can be adapted for actuation of the "clear air" key up to a selected number of times, while monitoring and accumulating the total fluid quantity delivered to a patient.

  • Patent number: 5611777
    Abstract: A steerable catheter includes control handle having a generally tubular housing with a longitudinal slot therein in which an axially or longitudinally movable two-part slideblock resides, and a generally cylindrical, rotatably mounted thumbwheel surrounding a distal portion of the tubular housing, for controlling the axial translation of the slideblock. The pullwire passes into the distal end of the control handle and is only secured to the proximal part of the two-part slideblock so as to prevent the user from placing the pullwire under compression. A tip radius adjusting wire is attached to and extends distally from a slide actuator in the control handle into and through the main catheter shaft portion. The free distal end of the tip radius adjusting wire is selectably Iocatable at different positions. The radius of curvature of the tip portion, when deflected, depends upon how far distally into the deflectable tip portion the radius adjusting wire has been advanced by the user.

  • Patent number: 5609590
    Abstract: An osmotic bursting device for dispensing a beneficial agent to an aqueous environment. The device comprises a beneficial agent and osmagent surrounded at least in part by a semipermeable membrane. Alternatively the beneficial agent may also function as the osmagent. The semipermeable membrane is permeable to water and substantially impermeable to the beneficial agent and osmagent. A trigger means is attached to the semipermeable membrane (e.g., joins two capsule halves). The trigger means is activated by a pH of from 3 to 9 and triggers the eventual, but sudden, delivery of the beneficial agent. These devices enable the pH-triggered release of the beneficial agent core as a bolus by osmotic bursting.

  • Patent number: 5607408
    Abstract: Skin treatment solutions are applied to the face, for example, by use of a flexible opaque mask 10. On a timed basis, one or more treatment solutions from vials 24-26 are provided to various facial areas via flexible tubes 20. In order to enable use of active treatment solutions including vitamin formulations subject to oxidation degradation in the presence of air, for example, a neutral atmosphere is provided. This is accomplished by supplying a neutral gas, such as nitrogen, from a cylinder 50 to mask 10 via flexible tubes 48. The neutral gas is infused between the mask 10 and the underlying skin at a low over pressure sufficient to drive air out from under the mask. Single treatment quantities of treatment solutions can be intermittently applied on a timed basis by the action of pump 36 operating under the control of programmable timers 30 and 40.
