  • Patent number: 8509916
    Abstract: Bilumen catheters and methods of using same for facilitating implantation of cardiac leads for applying electrical stimulation to and/or sensing electrical activity of the heart through one or more electrode positioned at an implantation site within a heart chamber or cardiac vessel adjacent a heart chamber, and more particularly to a method and apparatus for introducing such a cardiac lead having low torqueability and pushability through a tortuous pathway to enable attachment of the cardiac lead at the implantation site employing a bilumen guide catheter are disclosed. The bilumen catheter body includes a relatively large diameter delivery lumen to introduce a small diameter cardiac lead and a small diameter guide lumen to receive a stylet or guidewire to locate the guide catheter body distal end at the implantation site. The small diameter lumen within a small diameter guide tube extends distally from the delivery exit port of the delivery lumen.

  • Patent number: 5385281
    Abstract: A painter's utility belt provides for the carriage of at least one paint can and a variety of additional tools and equipment likely to be needed by a painter. The belt includes a first loop which may be secured about a paint can below the bail lugs on the sides of the can to support the can from the belt, and a second loop which may be secured about a section of PVC pipe or the like to provide for the storage of a caulking gun or the like therein. The loops are openable and adjustably closeable for different sizes of containers or the like, and are offset from the center of the belt to preclude interference with a ladder or other structure directly to the front of a wearer of the belt. An apron portion is also provided, with the apron having a plurality of open pockets of different sizes therein for the storage of various tools and articles.
