  • Patent number: 7008377
    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.

  • Patent number: 6234958
    Abstract: A medical device introduction system, a medical introducer, and related methods are provided. The medical device introduction system preferably includes a medical introducer having an introducer body and a plurality of lumen formed therein, an imaging device positioned in a predetermined one of the plurality of lumen of the medical introducer so that the imaging device is separately controllable independent of the medical introducer, and a separate steerable working channel device positioned in at least one other of the plurality of lumen of the medical introducer so that the separate steerable working channel device and the imaging device are separately controllable by a user thereof independent of each other. The separate steerable working channel device preferably includes an elongate tube portion having at least one lumen formed therein which defines the working channel and steering means associated with the elongate tube portion for steering the elongate tube portion.
