Patent number: 10342703Abstract: The invention relates to an ocular implant for treating glaucoma. The problem addressed by the invention is to make it possible to drain aqueous humor from the anterior chamber of the eye into the subconjunctival or suprachoroidal space in order to lower the intraocular pressure in glaucoma cases. The device is to do away with the drawbacks of known valve mechanisms and should be economical to produce. In order to solve said problem, the glaucoma drainage implant is composed of an elongate, hollow main member in which a flow-limiting membrane is arranged in the inflow region.Type: GrantFiled: February 23, 2015Date of Patent: July 9, 2019Assignee: Universitaet RostockInventors: Stefan Siewert, Frank Luderer, Wolfram Schmidt, Marian Loebler, Rudolf Guthoff, Katrin Sternberg, Klaus-Peter Schmitz

Patent number: 9592325Abstract: 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.Type: GrantFiled: August 7, 2008Date of Patent: March 14, 2017Assignee: Tepha, Inc.Inventors: Klaus-Peter Schmitz, Detlef Behrend, Katrin Sternberg, Niels Grabow, David Martin, Simon Williams

Patent number: 9162010Abstract: 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.Type: GrantFiled: October 28, 2011Date of Patent: October 20, 2015Assignee: Tepha, Inc.Inventors: Thomas Lenarz, Klaus-Peter Schmitz, Detlef Behrend, Katrin Sternberg, Simon Williams, David Martin

Patent number: 8206333Abstract: The present invention relates to an ocular implant, particularly a glaucoma stent. It is the object of the present invention to devise an ocular implant which allows the ocular eye pressure to be regulated, i.e., to be maintained at a desired level, while preventing the flow resistance from increasing over time, for example due to fibrosis. In order to achieve this object, the ocular implant according to the invention comprises a small tube (5), the wall surface (3) of which encloses a hollow duct that is open on both sides in the longitudinal direction of the hollow duct, wherein a first opening (1) allowing ocular humor to flow in and a second opening (2) allowing the ocular humor to be discharged is provided, and wherein the wall surface (3) is formed by a liquid-tight material, and wherein at least one pressure-controlled valve (4) is disposed in the area of the wall surface (3).Type: GrantFiled: January 25, 2008Date of Patent: June 26, 2012Assignee: Universitaet RostockInventors: Wolfram Schmidt, Katrin Sternberg, Detlef Behrend, Rudolf Guthoff, Klaus-Peter Schmitz
