  • Patent number: 7175741
    Abstract: Hydrogen sulfide is removed or reduced in absorbent products by the use of a particulate material attached to pulp fiber by a retention aid. The particulate material can remove or reduce the hydrogen sulfide in the environment surrounding the fiber. Suitable materials are zinc oxide, calcium oxide, cupric oxide, magnesium oxide, manganese dioxide, manganese oxide and aluminum oxide. Zeolites are also suitable. The particulate material may be combined with a filler prior to attachment to the fiber.

  • Patent number: 7054031
    Abstract: A method of color printing is described in which only two transparent inks are used to reproduce a source image The original digitally encoded image in red, green and blue colors may be initially adjusted for contrast, brightness, color balance, and tonal value. This is then converted to cyan, magenta and yellow encoding. The two of these channels which best represent the dominant colors of original image are then selected. The critical colors of the original image to be reproduced with reasonable accuracy are determined and spot colors that best represent these are selected from an ink palette The spot colors are assigned to the selected channels to which they have the closest color relationship. These two channels are next superimposed to form a composite image and their greyscale values are adjusted to produce an image most closely resembling the desired final image. New positive separations are then made and inverted to negative images from which printing plates can be prepared.

  • Publication number: 20060100630
    Abstract: Bone anchors are provided having three suture attachment sites disposed within a bore. The bone anchors are suitable for use in rotator cuff repair procedures. The bone anchors comprise an anchor body having a bore that opens at a proximal end of the anchor body. At least three attachment sites are positioned within the bore. Each attachment site is capable of slidably receiving a respective suture thereon. The three attachment sites are spaced apart and configured such that the portions of the respective sutures that are in contact with the three attachment sites are maintained separated during use. In one embodiment, the three suture attachment sites are provided by two transverse pins placed within the bore. In another embodiment, the bore opens at a distal end and a longitudinal pin is inserted into the opening at the distal end. The at least three attachment sites are provided by the longitudinal pin disposed within the bore.

  • Publication number: 20050283158
    Abstract: Improved bone anchors are disclosed for anchoring one or more sutures attached to soft tissue to a bone. The bone anchor has an anchor body that extends between a distal and a proximal end. A bore is formed axially in the anchor body and opens at the proximal end. One or more pins are fixed within the bore of the anchor body. One or more sutures can be looped on the pins for anchoring soft tissue to bone. The anchor body has a socket within the bore for receiving a driver tool. The distal end of the anchor body forms a non-threaded extension, which stabilizes the bone anchor, and helps prevent lateral movement during use. In one embodiment, the anchor body has coarse threads for engaging soft bone tissue and fine threads for engaging hard bone tissue.

  • Publication number: 20050277915
    Abstract: Electrosurgical devices for ablating tissue and methods of making the same are disclosed. The electrosurgical devices include an electrode with a lumen for aspirating gasses and debris produced during surgery. The electrode also includes a plurality of upper active edges for ablating tissue in an electrosurgical procedure. The upper active electrodes are spaced apart to form a filter that filters out large tissue particles from being aspirated into the lumen. The upper active edges ablate the large particles to form particles that can pass into the lumen. A lower active edge is formed at the terminal end of the lumen for ablating tissue being aspirated into the lumen. The lower active edge prevent tissue particles from occluding the opening to the lumen.

  • Publication number: 20050277916
    Abstract: An electrosurgical device having an electrode and an insulating piece such as a ceramic insulator is disclosed. The electrode includes an active surface for ablating and/or coagulating tissue in an electrosurgical procedure. The insulating piece surrounds the active surface and provides a barrier for the intense heat created during ablation. The insulating piece is also electrically nonconductive to prevent unwanted discharge of energy. Electrode has a retaining ledge configured to engage a lip formed on the insulating ring. The insulating ring is secured to the electrosurgical device by connecting the electrode to an electrode seat and capturing the insulating piece in between. The electrode can be connected to the electrode seat by projection welding. The insulating piece is connected to the electrode without the use of an adhesive.

  • Publication number: 20050133180
    Abstract: Densification agent and oil treated cellulose fibers exhibit densification properties that are superior to oil treated fibers that have not been treated with a densification agent and cellulose fibers that have not been treated with oil or a densification agent. The densification agent and oil treated cellulose fibers are useful in absorbent articles that may contain superabsorbent materials.

  • Publication number: 20050107777
    Abstract: An electrode configuration for use with a standard electrosurgical generator suitable for performing tissue ablation at relatively low power levels. The electrode has at least one curved wire member at its distal tip, the exposed conductive area of the curved wire member being minimized to create high power densities sufficient for tissue ablation. The exposed conductive area of the wire member is partially surrounded by a ceramic insulating support member to enable ablation laterally of the electrode tip as well as proximally and distally. An insulating layer is applied to portions of the outer surfaces of the electrode and the ceramic insulating support member.

  • Publication number: 20050049598
    Abstract: A suture pulley assembly includes a pulley wheel that is rotatably attached to an adjustable tension applicator used in joint repair surgery (e.g., to repair an ACL) so as to equalize the tensile load that is applied to each side of a looped suture by the adjustable tension applicator. The pulley wheel includes a pair of pulley plates that define a pulley space therebetween into which a looped suture is placed and that are oppositely-biased in order to spread apart and contract in response to differences in size of the looped suture as a result of, e.g., the existence of a knot or half knot. The pulley wheel is rotatably attached to the tension applicator by a post. A spring biases one of the suture pulley plates toward the other in a manner that allows for the aforementioned expansion of the pulley space.

  • Publication number: 20050049597
    Abstract: Suture separation and organization devices for use in a tissue graft tensioning system. The inventive devices help to separate and organize a plurality of suture strands that extend away from a bone tunnel of a patient's leg during joint repair surgery (e.g., while repairing or replacing the anterior cruciate ligament (“ACL”)). The suture separation and organization device may comprise one or more elongate bodies, or a one-piece body, comprising a plurality of suture retention recesses or protrusions disposed on a perimeter of a body. The suture separation and organization device also includes recesses or passages adapted to receive corresponding posts of a graft tensioning device. In this way, the suture separation and organization device can be removably attached to the graft tensioning device.

  • Publication number: 20050031841
    Abstract: Oil is used in absorbent structures to promote the retention of superabsorbent materials within the absorbent structures that are formed from fibers and the superabsorbent material. The oil is applied to either the fibers or the superabsorbent material or both prior to or during the formation of the components into an absorbent structure. Acquisition rates and fluid retention levels of the absorbent structures are described.
