  • Publication number: 20140276968
    Abstract: An applicator system for surgical fasteners includes an insertion tool having a shaft with a proximal end, a distal end, and an insertion fork connected to the distal end of the shaft, and at least one cartridge containing a plurality of surgical fasteners used for securing an implant to tissue. The surgical fasteners are removed one at a time from the cartridge by engaging one of the surgical fasteners with the insertion fork and removing the engaged surgical fastener from the cartridge. The insertion fork with the loaded surgical fastener is manually inserted through an implant and into tissue for securing the implant to the tissue.

  • Publication number: 20140275467
    Abstract: The present invention is directed to a novel polymerization process for making novel absorbable, linear polylactone polymers prepared using novel polymerization initiators to achieve rates of mechanical property loss or of absorption of articles made from the polymers that are at least about 1.2 times faster than the rates of mechanical property loss of polymers made by similar processes utilizing conventional initiators. The novel polymerization initiators include monols or diols possessing at least one primary alcohol group and two or more carboxylic acid groups. The invention also is directed to absorbable polylactone polymers prepared by processes of the present invention and to medical devices made from such polymers.

  • Publication number: 20140031788
    Abstract: Exoskeletal devices or sleeves that can be used with the delivery tube of an applicator device to help dispense fluids, typically flowable biocompatible materials such as hemostatic agents, adhesives, or sealants, onto specific sites in the human body for a medical reason are disclosed. The exoskeletal devices or sleeves are rigid, pre-shaped, and snappably or slidably affixed to the delivery tube. The exoskeletal devices or sleeves do not come into contact with the flowable biocompatible fluid being dispensed, and they can be placed at any position along the delivery tube to address different application situations. Once the exoskeletal device or sleeve is in place, it can optionally be locked onto the delivery tube to prevent further sliding under stresses when pushed against tissue. Multiple exoskeletal devices or sleeves can also be used to achieve more complicated shapes for hard-to-reach anatomical sites.
