  • Patent number: 6537566
    Abstract: The proliferation of uterine fibroid leiomyoma cells is inhibited by certain Fibroid Cell Growth Inhibitor (FGI) agents. The pharmacological doses of these FGI agents in the milieu of uterine fibroid cells can be made high enough to not only inhibit proliferation, but to also causes cell death. Non-invasive or minimally invasive, non-systemic delivery methods are used to deliver the FGI agent to the milieu of the target fibroid leiomyoma cell population, thereby avoiding the disadvantages and side effects of surgical and systemic hormonal therapy interventions in the treatment of uterine fibroids. The FGI agents are substrates that are normally present or are well tolerated in the human body. The efficacy of the FGI agents appears to be related to their ability to moderate the Protein Kinase C and Mitogen Activated Protein Kinase pathways. Specific FGI agents shown to be useful to inhibit growth or proliferation of uterine fibroid cells include: &agr;-tocopherol, &agr;-tocopherol succinate, and troglitazone.

  • Publication number: 20020114824
    Abstract: In a method of producing an iron core by punching and laminating stator core pieces and rotor core pieces from the same metal sheet, it is an object of the invention that magnetic pole teeth of the roughly punched stator core pieces are caused to stably develop by pressing toward space sides made by previously punching the rotor core pieces so as to sufficiently secure punching margins for pressing out the front tips of the magnetic pole teeth of the internal forms of the stator core pieces and the punching can be performed without obstacles even if a gap with the rotor core pieces is small, and further ruggedness formed on a surface of the metal sheet by pressing does not cause disturbances in a flow of magnetic flux.

  • Patent number: 6436428
    Abstract: Provided herein is a novel and useful device and method for locally delivering and controllably releasing oxybutynin in the cervical region of a female. A device of the invention comprises a ring comprising trifluoropropylmethyl/dimethyl siloxane elastomer. A pharmaceutical composition comprising oxybutynin and an excipient is placed within a bore located in the ring, wherein the bore runs from the surface of the ring into the ring. The ring has a sufficient size such that it can be inserted into the vaginal canal of a female. A cap comprising is placed over the bore at the surface of the ring in order to contain the pharmaceutical composition within the bore. When the ring is inserted into the vaginal canal, the trifluoropropylmethyl/dimethyl siloxane elastomer controllably releases and locally delivers a therapeutically effective amount of oxybutynin to the detrusor muscle to treat the female's urinary incontinence.

  • Patent number: 6361780
    Abstract: A drug delivery device is described comprising a porous biocompatible solid having at least one therapeutic drug within its pores, the therapeutic drug being removable from the pores by immersion in an aqueous solution. This may also be described as a drug delivery device comprising a porous annulus comprising a biocompatible solid having at least one therapeutic drug within its pores, the therapeutic drug being removable from the pores by immersion in an aqueous solution, the annulus having a top outer surface with an outside diameter, an inner surface with an inside diameter, and a side surface, at least one of the side surface and the top outer surface having openings of the pores exposed on that surface. The device may comprise pores having an average size of the greatest dimensions within the pores of between about 10−6 and 10−1 mm. The device may have a medical device or component of a medical device pass through an opening in the annulus.
