20090012604 | POLYMERIC, DEGRADABLE DRUG-ELUTING STENTS AND COATINGS - Absorbable stents and absorbable stent coatings have been developed with improved properties. These devices preferably comprise biocompatible copolymers or homopolymers of 4-hydroxybutyrate, and optionally poly-L-lactic acid and other absorbable polymers and additives. Compositions of these materials can be used to make absorbable stents that provide advantageous radial strengths, resistance to recoil and creep, can be plastically expanded on a balloon catheter, and can be deployed rapidly in vivo. Stent coatings derived from these materials provide biocompatible, uniform coatings that are ductile, and can be expanded without the coating cracking and/or delaminating and can be used as a coating matrix for drug incorporation. | 01-08-2009 |

20100268054 | Electrode Configuration and Measuring Device for Measuring the Electrical Activity in Electrically Active Tissue - An electrode arrangement for sensing electrical activity in target tissue is described. A support electrode has an elongate electrode body with a base end and a penetrating end for insertion into the target tissue. A fixation electrode has an elongate electrode body with a base end and a penetrating end at an angle to the electrode body. The electrodes are joined together with their electrode bodies in parallel so that the penetrating end of the fixation electrode penetrates a fixed distance into the target tissue so that at least one of the electrodes senses electrical activity in the target tissue. | 10-21-2010 |

20110282177 | Electrode Arrangement and Measuring Device for Measuring the Electrical Activity in an Electrically Active Tissue - The invention relates to an electrode arrangement and a measuring device for measuring the action flow and/or the action potential of an electrically active tissue. The aim of the invention is to provide a simple and economically producible electrode for measuring action flows and/or action potentials in electrically active tissues (preferably the stapedius muscle tissue), ensuring that the electrode is fixed securely, but reversibly, in the muscle tissue and that the muscle tissue is disturbed as little as possible. The electrode arrangement according to the invention comprises a first electrode ( | 11-17-2011 |
20120157815 | Evoked Stapedius Reflex Threshold (ESRT) Tile Electrode - An electrode arrangement is described for sensing electrical activity in target tissue. An inner electrode has an elongate electrode body formed as a cylindrical section with an inner penetrating end for insertion into the stapedius muscle target tissue. An outer electrode fits over the inner electrode and an outer penetrating end for insertion into the target tissue. The two electrodes are joined together with their electrode bodies in parallel so that the penetrating ends of the electrodes penetrate in the same direction into the target tissue to sense electrical activity in the target tissue. | 06-21-2012 |
20120283666 | DRUG ELUTING COCHLEAR IMPLANTS - Drug delivery systems and biocompatible coatings for use with implantable stimulation devices such as cochlear implants have been developed. These drug delivery systems and coatings comprise polyhydroxyalkanoate (PHA) polymers and copolymers. The drug delivery systems may be used to deliver pharmacologically active substances, for example, directly from a cochlear implant to the inner ear. The coatings can impart lubricity to cochlear devices for ease of insertion of the electrodes. In the preferred embodiment, the drug delivery system comprises a polyhydroxyalkanoate polymer, and in the most preferred embodiment, the PHA polymer comprises poly(4-hydroxybutyrate) (P(4HB)) or copolymer thereof. A particularly preferred embodiment is where the silicone sheath of the cochlear implant electrodes has been surface modified, and coated with P(4HB), and the P(4HB) either contains a pharmacologically active substance or has been coated with such a substance. | 11-08-2012 |

20140100471 | Electromechanical Measurement of Stapedius Muscle/Tendon Activity - A device for measuring stapedius tissue activity uses a mechanoelectrical transducer having two ends. A static end is configured for attachment to the bony pyramid in the middle ear, and a dynamic end is configured for attachment to stapedius tissue in the middle ear. The transducer generates a corresponding electrical sensing signal output when the stapedius tissue moves the dynamic end relative to the static end. | 04-10-2014 |
