  • Patent number: 5869096
    Abstract: An osmotic device (10) for delivering a beneficial drug, such as an anti-fungal, into the mouth of a human patient is disclosed. The device (10) has a size and shape adapting it to be comfortably retained in the mouth for extended periods of time. The device (10) comprises a wall (12) surrounding a compartment (13) housing a layer of an agent (14) that is insoluble to very soluble in aqueous biological fluids, e.g., saliva, and a layer (16) of a fluid swellable, hydrophilic polymer. A passageway (17) in the wall (12) connects the agent (14) with the exterior of the device (10). The wall (12) is permeable to the passage of aqueous biological fluid but substantially impermeable to the passage of the hydrophilic polymer (16). In one embodiment the beneficial agent (14) has a different color than the hydrophilic polymer (16). The wall (12) is sufficiently translucent to permit the patient to see the amount of drug/beneficial agent (14) remaining to be delivered.

  • Patent number: 5820587
    Abstract: A method is provided for preventing erectile dysfunction, particularly vasculogenic impotence, in a male individual. The method involves periodic administration of a vasoactive agent throughout a 24-hour period. The agent and dosage regimen are selected such that regularly increased blood flow to the penis is achieved, in turn preventing arterial occlusion and vascular deterioration of the muscular fibers of the vessels and collagen fibers of the cavernosal tissue.

  • Patent number: 5147654
    Abstract: An osmotic device (10) for the controlled systemic delivery of nicotine through an oral mucosal membrane of a human patient is disclosed. The device (10) has a size and shape adapting it to be comfortably retained in the mouth for extended periods of time. The device (10) comprises a semipermeable wall (12) surrounding a compartment (13) containing a nicotine salt (14) and optionally an alkaline salt which is capable of reacting with the nicotine salt in the presence of water to form nicotine base. The conversion of nicotine salt to nicotine base may take place within the device (10) and/or outside the device and in the patient's mouth. Nicotine base and/or salt is delivered from the compartment (13) through a passageway (17) in the wall (12). The nicotine salt exhibits good stability and shelf life while the nicotine base exhibits excellent absorption through oral mucosal membranes.

  • Patent number: 4867982
    Abstract: A medical device for the transdermal delivery of an active agent through sensitive intact skin is provided. The device comprises a matrix containing the drug having reinforcing means, preferably in the form of a fabric, embedded in the upper surface of the matrix. The matrix is formed of an agent permeable material which is tacky but does not adhesively bond to the skin. The device is sufficiently flexible and deformable that the combination of tackiness, flexibility, and deformation permits the device to be maintained in agent transmitting relationship upon skin at such sensitive areas as the scrotum, labia, breast, or penis, for example. In certain embodiments, the skin distal surface is provided with a layer of an agent impermeable material to reduce transfer of the agent from the patient to others.

  • Patent number: 4631060
    Abstract: A vaginal spermicide distributing membrane comprises a relatively thin flexible membrane having a plurality of integral rings of thicker dimension on one or both sides thereof. Each ring can have a depression along its surface that functions as a receptacle for spermicide. The rings provide sufficient resistance to deformation so that when the membrane is flexed for insertion in the vagina, it will tend to assume a planar shape and be held in contact with the vaginal mucosa. The rings keep the device properly positioned and function as successive barriers to sperm migration. Loops provided along the periphery of the membrane assist in its insertion and removal.

  • Patent number: 4539004
    Abstract: A pump assembly particularly useful as an infusor for parenteral administration of a small amount of a therapeutically active substance for a prolonged period of time at a substantially constant rate comprising a fluid imbibing pump mounted within a receptacle into which actuating fluid may be charged. The active agent is dispensed from the pump after the pump is exposed to the fluid. Means to vary or stop the pump by obdurating all or a portion of the exterior surface of the pump can also be provided. Variation in flow rates can also be obtained by changing the composition of the actuating fluid.
