  • Publication number: 20150314035
    Abstract: The disclosure provides compositions, systems, and methods for the treatment of pelvic tissue conditions that include use of a silk fibroin-containing hydrogel composition. The composition includes water-soluble fibroin and a water-soluble crosslinkable polymer. The composition can be used as a pre-formed hydrogel or can be delivered to a pelvic tissue site and crosslinked in situ to form a hydrogel. The composition can be used to promote tissue closure, such as vaginal wound or fistula closure. The composition can also be used to enhance attachment or anchoring of a pelvic implant to a pelvic tissue. A hydrogel delivered to a pelvic tissue site, or formed at the site in situ, is associated with a portion of the implant (e.g., a mesh implant) via a tether or implant extension portion, thereby providing improved immobilization of the implant. Systems or kits that include the composition and a delivery needle or insertion tool are also described.

  • Patent number: 9095425
    Abstract: An injector for inserting an intraocular lens into an eye, comprising a main body (10) and a plunger (50). A guide element (30) is connected to the distal end of the plunger to laterally guide the plunger during movement along a longitudinal axis (L). The distal end of the guide element has a structure for fastening a plunger needle to the guide element. A radial guide pin (40) is in aligned radial bores of the guide element and plunger and extends into a longitudinal slot (17) of the main body to prevent twisting and to secure the guide element to the plunger. A retaining element (24) interacts with a running surface on the perimeter of the plunger, the running surface having a variable radial distance from the longitudinal axis so as to cause an axial resistance force which depends on the axial position of the plunger.

  • Patent number: 9060804
    Abstract: A cleaning apparatus for microsurgical instruments of the type having screw-type mechanisms used to advance or retract a plunger has a hollow sleeve into which the injector is liquid-tightly inserted, the sleeve being configured to hold the plunger in a fixed position when the plunger is disengaged from the injector body. A cap having an inlet port is liquid-tightly attached to the sleeve and cleaning liquid is forced from a syringe into and through the inlet port, flushing detritus from the injector. Various sizes and shapes of sleeves are used to accommodate different injectors.

  • Patent number: 8932694
    Abstract: The invention provides fluorinated polymeric articles formed a composition including a fluoropolymer. The fluoropolymer is formed using a fluorinated monomer that provides the fluoropolymer with most or all of the fluorine atoms not directly covalently attached to an atom of the fluoropolymer backbone. The fluoropolymer can also include a non-fluorinated hydrophilic monomer in a weight amount greater than the fluorinated monomer. The fluoropolymer composition also includes an ultraviolet light (UV)-reactive group capable of covalent bonding to promotes formation of the fluorinated polymeric article. The fluorinated polymeric article can be in the form of a durable lubricious coating on the surface of an implantable medical device. Coatings of the invention exhibit excellent wet/dry lubricity, durability, and controlled swelling.

  • Publication number: 20140246057
    Abstract: A cleaning apparatus for microsurgical instruments has a flush chamber closed off at one end by a first plug adapted to liquid-tightly grip one end of the instrument, allowing a portion of the instrument to extend past the first plug and out of the flush chamber. The other end of the flush chamber is closed off by a second plug having an inlet port. Liquid injected through the inlet port on the second plug passes through an internal passageway formed in the instrument and exits the instrument through the portion that extends past the first plug. In another embodiment the instrument has an internal passageway and an end cap through which flushing ports are formed which communicate with the passageway. A first plug having an inlet port is liquid-tightly attached to the end cap and liquid injected into the first plug passes through the plug, through the flushing ports and through the passageway to clean detritus from the instrument.

  • Patent number: 8722076
    Abstract: The invention provides polymers comprising pendent photochrome or near IR dye groups, as well as polymeric matrices made from these polymers, which can be used as or in association with a medical article. The polymers can be synthesized using methods that facilitate the preparation of medical articles having good biocompatibility. Exemplary polymeric matrices are in the form of lubricious coatings on medical devices, such as catheters. Visualization by irradiation of the photochrome or near IR dye can improve detection of the polymeric matrix on a device or in the body. This, in turn can improve aspects of a medical procedure, such as device insertion or matrix formation, as well as being useful for assessing the quality of the matrix.

  • Patent number: 8586731
    Abstract: Hydrophobic ?(1?4)glucopyranose polymers with enhanced degradation properties are described. Between the ?(1?4)glucopyranose polymeric portion and the hydrophobic portion exists a linker portion having a chemistry that facilitates degradation of the polymer. Diester and carbonate ester linker chemistries are exemplified. Biodegradable matrices can be formed from these polymers, and the matrices can be used for the preparation of implantable and injectable medical devices wherein the matrix is capable of degrading in vivo at an increased rate. Matrices including and capable of releasing a bioactive agent in vivo are also described.
