  • Publication number: 20120165786
    Abstract: The present invention relates compositions for delivering therapeutic agents from a medical device including an expandable and collapsible structure and methods employing them. A lipid coating including one or more fatty acids increases the amount of therapeutic agent released from the device at the delivery site. The therapeutic agent can be in a matrix including a hydrophilic polymer or an amphiphilic polymer. Release and adhesion coatings can also facilitate delivery of therapeutic agent.

  • Publication number: 20120114589
    Abstract: The invention provides biodegradable polymeric hydrogel matrices having excellent durability and swellability. The matrices are formed from a combination of poly-?(1?4)glucopyranose macromer and a biocompatible biostable hydrophilic macromer. The matrices can be used in association with a medical device or alone. In some methods the polymeric matrix is placed or formed at a target site in which the matrix swells and occludes the target area, and is able to be degraded at the target site after period of time.

  • Publication number: 20120082713
    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: 8103015
    Abstract: There are proposed wireless headphones which have at least one electroacoustic transducer for the reproduction of audio signals, a receiver for receiving wirelessly transmitted audio data, an intermediate memory for putting the received audio data into intermediate storage, an audio decoding unit and a control unit. The audio data wirelessly received by the receiver are firstly buffered or put into intermediate storage in the intermediate memory. The control unit controls reading of the compressed audio data stored in the intermediate memory so that said data are passed to the audio decoding unit where the compressed audio data are decoded and then outputted by means of the electroacoustic transducers. Wireless transmission is effected at a higher speed than the reproduction of the stored audio signals.

  • Publication number: 20110318575
    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: 20110094599
    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.

  • Publication number: 20100316687
    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.

  • Publication number: 20090240257
    Abstract: An injector having a hollow cylindrical body having a first, discharge end and a second, plunger end, and a plunger which is axially slidable within the body. A first end of the plunger is adapted to contact either an IOL or a cartridge containing an IOL and to force the IOL out of the injector or cartridge into the eye. A second end of the plunger has a knob or stop proximate the pushing end, used to grip the plunger and move it into the housing. Located on the housing proximate the second end is a micrometer barrel rotatably and threadedly mounted to the injector housing. When the plunger is fully pushed into the injector housing, the knob contacts the micrometer collar thus halting the inward movement of the plunger. The micrometer collar is rotatably adjustable with respect to the housing thereby altering the position at which the plunger knob contacts the micrometer dial and, thereby, adjusting the distance to which the the plunger extends toward or past the discharge end of the injector.

  • Patent number: 7574011
    Abstract: The invention is based on the idea of providing a detection device which is capable of distinguishing whether a microphone or audio signal processing arrangement connected thereto operates on an analog or digital basis. An analog or digital connection is selected in accordance with that determination procedure. Consequently there is provided a detection device which has a sensing device, a determining device and a selecting device. The sensing device senses an external signal fed to the detection device and forwards that signal to the determining device. The determining device determines whether the sensed external signal was transmitted by an analog or digital signal processing apparatus and transmits a corresponding determination signal to the selecting device. The selecting device then selects either an analog or a digital connection, in dependence on the determination signal.

  • Patent number: 7335209
    Abstract: A plunger needle (3) for an intraocular lens injector has a plunger tip (4) with a contact area for making contact with a lens (L), the contact area being arranged in a front face (40) of the plunger tip (4), which is curved cylindrically. The plunger needle (3) according to the invention, with its specially configured plunger tip (3), permits reliable guiding of the lens (L) upon injection into an eye and prevents the lens (L) becoming stuck in the injector.
