  • Patent number: 6955819
    Abstract: The present invention is directed toward an apparatus to rapidly deliver a drug to a patient The invention comprises a drug beneath a patient's skin in a drug depot site. A heating component is placed near the drug depot site and generates heat in and near the drug depot site. A control component connected to the heating component is used to control the magnitude and duration of heat generated by the heating component.
    Type: Grant

  • Patent number: 6756053
    Abstract: The present invention is directed to a method and system for delivering a drug into the systemic circulation. The method comprises establishing a drug depot in a patient's skin and/or sub-skin tissues by applying a transdermal drug delivery system on the patients skin, for a predetermined time so that a drug depot is formed in said user's skin and/or sub-skin tissues. A heating source is placed proximate to the skin area to rapidly release a bolus of the drug from the depot into the systemic circulation when there is a need to rapidly increase the drug's concentrations in the systemic circulation.

  • Patent number: 6726673
    Abstract: The present invention relates to a method and apparatus for increasing the delivery rate of an androgen transdermal therapeutic system through the skin. An androgen transdermal therapeutic system can be applied to a patient's skin for delivery of the androgen. A temperature modification apparatus which is capable of generating controlled heat is applied approximate to the androgen transdermal therapeutic system. The heating from the temperature modification apparatus raises the temperature of the androgen transdermal therapeutic system and raises the temperature of the patient's skin to achieve an increased rate of delivery of androgen through the skin. The controlled heat can also be used to adjust dosage rates of the androgen transdermal therapeutic system and to mimic natural circadian patterns. The controlled heating may also be used to improve or regulate the release of androgen from injected/implanted extended/controlled release systems.

  • Patent number: 6546281
    Abstract: An integrated apparatus for controlled heat aided dermal drug delivery is disclosed. The apparatus has a temperature control component and a drug delivery component. The temperature control component may and dermal drug delivery component are an integrated unit. The apparatus also comprises means to prevent exchange of substance(s) among the heat generating component, the drug delivery component and the outside environment. The apparatus is designed to be easy to use.

  • Patent number: 6488959
    Abstract: The present invention relates to a transdermal drug delivery system comprising a dermal drug delivery patch and a heating element compartment securable to the dermal drug delivery patch. A freely transferrable heating element is securable within the heating element compartment. A drug can be administered transdermally using the present invention by placing the dermal drug delivery patch upon a patient's skin at an administration site. A heating element compartment is secured to the dermal drug delivery patch and a freely transferrable heating element is placed within the heating element compartment. The heating element provides controlled heat to the dermal drug patch and the patient's skin and thereby improves dermal drug administration.

  • Patent number: 6453648
    Abstract: The present invention relates to a method for manufacturing a heating device which is capable of generating heat when exposed to oxygen. The heat generating element comprises activated carbon and iron is used to generate an exothermic oxidation reaction within the heating device. Introducing an oxidation inhibitor during the manufacturing process allows the manufacturing of the device to take place in ambient atmospheric conditions. The present invention also includes a loading facilitator which allows the heat generating medium to be more easily and efficiently loaded into the heat generating device. When appropriate, the oxidation inhibitor and loading facilitator can be removed.
