  • Publication number: 20150112278
    Abstract: Systems and methods for placement of an introducer needle into the subclavian vein. A needle for subclavian vein penetration includes a straight needle portion, a bent needle portion, and a hub. The bent portion allows for needle placement with minimized chance of complications. The needle and hub form a lumen through which a guide wire can be placed. The bent needle portion has an inner diameter substantially similar to the inner diameter of the straight needle portion to reduce resistance due to movement of the guide wire.

  • Publication number: 20100331812
    Abstract: The present invention describes pharmaceutical formulations and methods suitable for iontophoretic delivery of the formulations to a subject. The formulations comprise an immunomodulator, such as imiquimod, and optionally include various agents and excipients. The formulations can be used as a treatment for skin diseases and conditions such as actinic keratosis, basal cell carcinoma and genital warts. The short term iontophoretic delivery of the formulations results in the creation of a depot effect in the skin of the subject, allowing for a sustained delivery. The shortened delivery time minimizes local side effects at the application site.

  • Publication number: 20080319371
    Abstract: A method to electrokinetically deliver a medicament to a nail of a mammalian user including: forming a cast of the nail of the user wherein the cast is a reverse impression of the nail; applying a medicament matrix to the nail; sandwiching the medicament matrix between the cast and the nail; pressing the medicament matrix to the nail using the cast; applying electrical current to an electrical current path extending through the medicament matrix and the nail, and delivering medicament from the matrix into the nail by electrokinetic transporting the medicament along the current path.
