  • Publication number: 20060161049
    Abstract: A device for retracting edges of an incision in a surface to form an opening including: a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween; a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel; and an inflatable collar connected to the skirt and surrounding the upper end. The ring is designed to fit through the incision and remain under the surface when it is oriented parallel to surface. The collar, when inflated, maintains the upper end in an open configuration and defines an entry opening to the channel. During use, the ring is inserted through the incision and the collar is inflated while remaining outside of the incision, thereby drawing the skirt against the edges of the incision and retracting the edges of the incision to form the opening.

  • Publication number: 20040034357
    Abstract: Implantable devices that deliver a drug to a target location are disclosed. In general, the devices include a portion that engages tissue near the target location and a section with an internal cavity that houses the drug. The drug can be incorporated into a controlled release agent, such as drug-polymer microspheres, which steadily or intermittently release the drug. Alternatively, instead of defining an internal cavity, the section can be formed from a material that includes the controlled release agent. The devices can be used, e.g., to deliver down-regulatory cytokines to a site of inflammation.
