  • Publication number: 20050277802
    Abstract: A method for performing intraocular brachytherapy and an apparatus for performing the same is disclosed. The apparatus preferably comprises a hand-held delivery device that advances a radiation source into an associated cannula or probe that is positioned adjacent the target tissue. The handpiece provides for shielded storage of the radiation source when retracted from the cannula and includes a slider mechanism for advancing and retracting the radiation source. The radiation source is mounted to a wire that has a flexible distal end and a relatively stiffer proximal end. A positioning system for the cannula is also disclosed.

  • Publication number: 20050218393
    Abstract: A fencing system has a pair of fence posts that are vertically oriented. A pair of horizontally oriented rails connects the fence posts. A fence panel has several vertical wires and several pairs of vertically spaced horizontal wires. An upper portion of the fence panel is held within one of the rails and a lower portion of the fence panel is within the other rail. A retainer can be used to hold the fence panel within the rails. The retainer has a slot for surrounding a wire of the panel so that a horizontal wire of the panel is captured between the retainer and the rail.

  • Publication number: 20050071983
    Abstract: A picket fence and rail mounting system that is easily transformable by the consumer into a variety of aesthetic styles is provided. The system comprises at least an upper and a lower elongate rail. Each rail has a hollow interior defining a substantially I-shaped cross-section including at least a first slot and a second slot. A plurality of pickets are transversely slidable through openings in an upper surface of the rails and a channel in a lower surface. The pickets each have at least a first notch or indentation near a first end and a second notch or indentation near a second end. The distance from the first end to the first notch or indentation is preferably shorter than the distance from the second end to the second notch or indentation. An elongate retaining rod slidable within at least one rail cooperates with a notch or indentation on each picket to secure the picket to the rail.

  • Patent number: 5221259
    Abstract: A wound clotting device is disclosed comprising a clotting device for dispensing a clotting agent onto a selected location in a patient while being retained adjacent to that location, comprising a tube having a proximal end portion and a distal end portion; means defining an inflation lumen in said tube extending between said proximal and distal end portions; inflatable retention means carried by said tube at said distal end portion for retaining said distal end at a selected location within the body of a living patient, said retention means being in fluid communication with said inflation lumen; means defining a second lumen in said tube extending between said proximal and distal end portions; means for receiving a quantity of clotting agent located within said second lumen; and means disposed within said second lumen for dispensing said clotting agent from said distal end of said second lumen to deposit said clotting agent at said selected location within a patient.
